Dup of #19200?

OneOfOne on 11 Jul 2017

See in-progress dup issue #19200.

You'll need to use gccgo. There are no plans for the gc compiler (the one from golang.org) to support AIX, but the gccgo compiler should work. Or it appears that it's increasingly working.

Closing as dup of #19200.

Thank you, Is there a tutorial on how to configure gccgo? I have gcc installed but it seems not as easy to use it with gccgo...

We (BullFreeware project) have ported gccgo on AIX.
It is a first release. Further release should fix some more issues (mainly in libgo).

You need to download and install GCC 7.1.0-7 (for AIX 7.1 and 7.2) or GCC 7.1.0-6 (for AIX 6.1).
It is delivered as RPMs.
Look at: http://www.bullfreeware.com/search.php?package=gcc&version=aix7.2
gcc-go-7.1.0-7 for aix7.2 is available at: http://www.bullfreeware.com/affichage.php?id=3733
You'll have to download and install all dependencies (and some more).

There are 3 RPMs:
gcc-go-7.1.0-7.aix7.2.ppc.rpm
libgo-7.1.0-7.aix7.2.ppc.rpm
libgo-devel-7.1.0-7.aix7.2.ppc.rpm
requiring other RPMs (from GCC 7.1.0, and more).

What you have to do:
Let say you have a path = /X/Y/Z/src where is your Go code.
Do:
export GOPATH=/X/Y/Z
cd $GOPATH/src/
go build

go version
go version go1.8.1 gccgo (GCC) 7.1.0 aix/ppc

Let me know if you succeed to use it.

Current test status:

go compiler tests : 4 failures out of 7358 tests
libgo tests (32bit) : failing tests:
fmt : TestCountMallocs
log : TestAll
net : TestConnAndListener : SIGILL: illegal instruction

(SIGILL failures deal with dereferencing function reference)
("out of memory" and "timed out" deal with issue in GccGo or limitation on AIX, for now)

Big thanks @trex58 ! I Will test it tomorrow.. I was close to stop the benchmark of golang for my project..

toussaiv on 12 Jul 2017

Thanks @trex58 , I finally managed to make it work on 7.1! But what I was expected became true => the binary produce with the go compiler on 7.1 is not working on AIX 6.2 : ( . So go language is not a wonderful cross platform tool as I thought ;(.

Last question => Do you know if some day AIX will be support officialy?

toussaiv on 13 Jul 2017

About Gcc Go for AIX 7.1, look at:
http://www.bullfreeware.com/search.php?package=gcc&version=aix7.1

Go & libgo for AIX 7.1 :
gcc go : http://www.bullfreeware.com/affichage.php?id=3722
libgo : http://www.bullfreeware.com/affichage.php?id=3723
libgo-devel : http://www.bullfreeware.com/affichage.php?id=3724

In general, all RPM packages built for AIX 6.1 can be used on AIX 7.1 and 7.2, except Gcc (and Gcc Go), and some more RPMs (PostgreSQL).

trex58 on 13 Jul 2017

Hummm A binary produced on AIX 7.1 does not work on AIX 6.1 ?
I never experimented this. I'll do.
What are the error messages ? Discuss with me at: tony dot reix at atos dot net .

About Gcc Go beeing officialy supported on AIX, there are 2 ways:

we are submitting our patches to FSF and Google in GCC v8: next year, when Gcc v8 is in GA, the code required for Gcc Go on AIX should be available in Gcc v8 code.
some day IBM should reuse our work and deliver an "official" version of Gcc Go 7.1.0 for AIX on their "AIX Toolbox" web-site: http://www-03.ibm.com/systems/power/software/aix/linux/toolbox/alpha.html

Moreover, we still are working on solving issues in libgo, and there are bugs and limitations in Gcc Go that prevent some features to run correctly on AIX. (AIX/Power architecture is different from Linux/x86_64 and some Go code is provinding code that was not used on Linux/x86_64 but is used on AIX/Power).

trex58 on 13 Jul 2017

The executables produced by GCC Go depend on Go packages that are provided by libgo.a.
It also requires libgcc_s.a .
Bof of them are provided by GCC libraries:
rpm -q --whatprovides /opt/freeware/lib/libgo.a
libgo-7.1.0-7
rpm -q --whatprovides /opt/freeware/lib/libgcc_s.a
libgcc-7.1.0-7

Thus, you can compile on AIX 7.2 and run it on AIX 6.1, if same version of GCC Go is installed (libgo and libgcc RPMs) on the AIX 6.1 machine.

cat Hello.go
package main
import "fmt"
func main() {
fmt.Println("Hello World!")
}

go build Hello.go

./Hello
Hello World!

ldd ./Hello
./Hello needs:
/usr/lib/libc.a(shr.o)
/opt/freeware/lib/libgo.a(libgo.so.11)
/opt/freeware/lib/libgcc_s.a(shr.o)
/usr/lib/librtl.a(shr.o)
/unix
/usr/lib/libcrypt.a(shr.o)
/usr/lib/libpthread.a(shr_xpg5.o)
/usr/lib/libpthread.a(shr_comm.o)
/usr/lib/libpthreads.a(shr_comm.o)

One can compile with -static-go in order of no more be dependent on libgo.a . However, the a.out file will be big (>= 68MB).
gccgo Hello.go -static-libgo
./a.out

trex58 on 13 Jul 2017

@trex58 Interesting project. I'd like to know more about the current status (couldn't find the info on the BullFreeware site, but can see new versions). Would compiling Telegraf be feasible?

tw-bert on 10 Dec 2017

Hi, we are continuously improving the port on AIX, submitting changes to the Go and GCC projects. See: https://go-review.googlesource.com/q/reix (and old: https://go-review.googlesource.com/q/sarter) . I've recently produced a new snapshot of GCC 8 (20171205), which enables to build Filebeat 6.0, Kubernetes 1.8, and more. Take it at: http://www.bullfreeware.com/go/go8.0.0/aix7.2/ . And I know I'll have to teach AIX to golang.org/x asap.
About Telegraf, I have no idea. Let me know where I can download it and have a look at it.

trex58 on 11 Dec 2017

@trex58 Thanks for the info, great stuff. Telegraf: see here . It is a metrics collector, similar to collectd (which some people have succesfully compiled on AIX by the way - I will give it a go if Telegraf's a no-go).

tw-bert on 11 Dec 2017

@tw-bert I have issues on AIX. That probably deals (as usual) with AIX operating system not managed in some code. Not difficult to work it around.
However, on Linux/Power and Linux/x86_64, though the errors I see on AIX do not appear, there are error messages, like:
undefined reference to `github_com_influxdata_telegraf_plugins_inputs_couchdb.metaData$hash'
That's a deeper error.
I've warned the GCC Go team.

Version 7.2.0 is available on AIX: version for AIX 7.2 :
http://www.bullfreeware.com/search.php?package=gcc&version=aix7.2

A snapshot of GCC 8.0.0 for AIX made the 5th of December is available at:
http://www.bullfreeware.com/go/go8.0.0/aix7.2/ .
It enables to build Kubernetes and other Go applications. Even in 64bits (ppc64), though there are some issues with 32bit .gox files used instead of 64bit .gox files. Being fixed right now.

Today snapshot of GCC Go 8.0.0 now integrates Go v1.10 , making Go runtime on AIX to crash. We are working on fixing this.

trex58 on 10 Jan 2018

@trex58 With the latest changes, do you think it's worth trying to build Telegraf again?

tw-bert on 18 Feb 2018

Version 8.0.1, snapshot 20180206, for AIX 7.2, is available on BullFreeware:
http://www.bullfreeware.com/go/go8.0.1/aix7.2/

About Telegraf, the maintainer of GCC Go said to me, the 25th of January: "I believe this program is fixed now." Please give it a try with this version 8.0.1 .

@trex58 Thanks for keeping us posted. I have to find the time to give it the attention it deserves.
I ran into some package dependency problems, not related to your work, but since we don't have a spare AIX server I have to create a proper chroot jail on our shared dev machine first before I can properly test it.

We have improved the time needed for starting a Go a.out within last versions of GCC Go 8.0.1 .
About AIX 6.1, since it does not contains features required for cgo (and also recent DWARF), we plan to deliver GCC Go only/mainly on AIX 7.2 .

trex58 on 3 Apr 2018

@trex58 can we build static on AIX 7.2 than run on AIX 6.1 to solve this problem

better0332 on 3 Apr 2018

"Build Go static on AIX 7.2 that runs on AIX 6.1" ? Hummm AIX guarantees ascendent compatibility only. I fear that, in the reverse way, it will not work. I do not have GCC 8.0.1 installed on my AIX 6.1 machine. So I cannot test.
On AIX 7.1, GCC Go should work quite fine. However, for now, I haven't built/tested on AIX 7.1 . I'm still focused on AIX 7.2 where there are still tests failures (however, that does not prevent Kubernetes to compile and run).

trex58 on 3 Apr 2018

@tw-bert I test on AIX7.1, it same as before. Which version do you use？The GCC 8.0.1 rpm version can only install on AIX7.2

better0332 on 4 Apr 2018

Latest version on AIX 7.2 (which is my main Gcc Go development environment) is: gcc-8.0.1-20180305 .
I have a 8.0.1-20180206 version available for AIX 7.1 . Let me know if this version would help you. If yes, I'll push it on BullFreeware.
Meanwhile, I'll launch a build of 8.0.1-20180305 on AIX 7.1 .
And I plan to update 8.0.1 on AIX 7.2 with a recent snapshot.

Is there binary version of recent filebeat (6.2.4 or 6.2.3) compiled for AIX 7.2 ? Latest binary version on Bull Freeware http://www.bullfreeware.com/go/ is of version 6.0.0-alpha. Thanks, Luca

lucket on 11 May 2018

Hi Luca
Hummmm I do not remember why I provided this version of Filebeat one year ago...
Anyway, I'll soon publish GCC 8.1.0 (with Go v1.10) on the main pages of BullFreeware. And you should be able to build Filebeat by yourself. Let me know if you cannot.
Moreover, remember that the way GCC Go is architectured is probably not yet stable, meaning that objects or libraries built by means of a version A of GCC Go may not be compatible with other objects and libraries builds by means of a version B of GCC Go. An executable should be built by compiling all the source codes it depends by means of the SAME version of GCC Go.

Hey guys!
Any of you managed to workaround the "_kgrantpt" issue?

I'm on AIX7.1 and hit the same problem.

$ go build -gccgoflags '-v -static -lcrypt' main.go
.
. tons of output...
.
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.
ld: 0711-317 ERROR: Undefined symbol: _kgrantpt
collect2: error: ld returned 8 exit status

Hi
It is not a symbol in gcc-go & libgo RPMs of GCC v8.2 for AIX 7.2 nor AIX 7.1 .
It is a symbol appearing in AIX kernel.
Using -static implies that the libc.a will be included into the a.out .
_kgrantpt appears in a pty.exp that should appear in /usr/lib and a -bI instruction should fix the issue. However, it is not delivered by AIX... We guess that IBM does not want to make this part of AIX public. And probably also using -static on AIX is not recommended since libc.a may change between 2 sub-versions (TL) of a AIX version and that may result in weird issues.

I think that you should use: -static-libgo -static-libgcc instead.

trex58 on 1 Oct 2018

Hi @trex58, thanks for the in-depth response.

I managed to build using -static-libgo -static-libgcc as you suggested.

Another question: Would it be possible to build a "static" binary that could run on AIX 6.x?
And... there's no hope of running a Go binary on AIX 5.x, right?

Running the binary built with -static-libgo -static-libgcc on an AIX 6.1 throws the following errors:

The AIX version and gccgo version I'm using to build the binary:

bash-4.4# go version
go version go1.10.3 gccgo (GCC) 8.2.0 aix/ppc
bash-4.4#
bash-4.4# gccgo --version

bash-4.4#
bash-4.4# oslevel -s

bash-4.4#

I suspect it have something to do with the libc.a being different, as you already pointed out. There's some way of working around it?

Thanks in advance!

Hi Felipe,
No, sorry, it it impossible to have GCC Go on AIX 5.x .
About AIX 6.1, we have stopped to port Go on it because (as far as I can remember) this AIX version lacks some feature (DWARF ?) that are required for correctly implementing important Go features. For now, GCC Go v8 requires AIX >=7.1 . Only GCC Go v7.2 is available on AIX 6.1 . About golang v1.11 on AIX, it requires AIX >= 7.2 (TL2 is better than TL0) and Power >= 8 .
So, you say that you build Go HelloWorld on AIX 7.1 TL5 with GCC 8.2.0 and you execute it on AIX 6.1 . Wowww ! AIX provides upward compatibility only. As an example, the openat() routine is not provided by AIX 6.1 TL9 . Moreover, based on document http://public.dhe.ibm.com/systems/power/docs/aix/61/aixcmds4_pdf.pdf , it seems that no TL of AIX 6.1 provides the openat() routine (and some other routines of this family). I've studied this openat() routine already for the port of MariaDB, and openat() cannot be easily implemented.
So, unless I try again to build GCC Go 8.2 on AIX 6.1 in order to remind what exactly is missing (but I have plenty other things to do before), I think that you have to use AIX 7.1 for running Go programs.
Regards,

golang v1.11.1 has been delivered on BullFreeware.
Still for AIX 7.2 and Power >=8 only.
http://www.bullfreeware.com/search.php?package=golang
Next version v1.12 for AIX should be made available from golang web-site, in addition to BullFreeware. In February.

The openat() family (which comes from POSIX 2008) was introduced with AIX 7.1

golang 1.11.4 is available on BullFreeware.
Still for AIX 7.2 and Power >= 8 only.

Build of golang v1.12 on AIX starts to appear "ok" on the golang buildfarm:

Just to make sure I understand, cross compilation is not available as in the OP question? With gccgo we still need to build on AIX?

sfc-tbrown on 21 Dec 2018

@sfc-tbrown AFAIK, yes... you still need to build gcc-go for AIX, and then used it to build Go binaries for AIX

To run on AIX 6.x I needed to build gccgo for AIX 6, and the same for AIX 7

HI team
i am face an issue on export a C static library from Go via GCCGO compiler on AIX 7.2. my GO code below :
package main

//#include
//#include
import "C"
import "fmt"

//export printHello
func printHello() {
fmt.Println("hello nuts!")
}

func main() {
// for c build
}
the command i used to compile it is : go build -compiler gccgo -buildmode=c-archive -o caculator.a -gccgoflags '-lgo -static' wrapper.go
then i got a c static library caculator.a , then i use it in a c program as below :

include

include "caculator.h"

int main()
{
int a=12;
int b=13;
printf("Hello, let's test caculator!");
printHello();
printf("result:%d",12131231);
}
then i tried compile this c program with : gcc -o app main.c caculator.a -pthread
then i got a exec file: app
but when i tried to run it , it seems run into a deadlock , nothing print out \
, anyone have an idea on this ?

i have the gcc,gccgo installed and i ma able to compile and run go program without CGO correctly .

thanks a lot

Hello,
I'm able to run this code perfectly on Linux/Power with some old GCC Go (plus -lm for math).
It is an issue in AIX. It looks like "runtime_init_done" in libgo/runtime/go-cgo.c is not set, thus showing initialization has not been done.
Investigating.

Go: gccgo: Is there a way to build a binary which will be run on AIX? what GOARCH and GOOS should I choose?

What version of Go are you using (`go version`)?

What operating system and processor architecture are you using (`go env`)?
