Openblas: Building OpenBLAS with MinGW from msys2.org fails

[witignite]

I am trying to build OpenBLAS on Windows 10, strictly following the instruction in this link under the section "Build OpenBLAS on Windows OS". The environment I'm using is Windows 10, Intel core i5-6200u, MinGW64 from http://www.msys2.org. The following is the full message shown in the MSYS2 MinGW 64-bit shell after rerunning the command again after the first error.

What could be the source of this error?
<command-line>:0:4: error: expected identifier or '(' before numeric constant

[martin-frbg]

Sorry, I have no idea right now what could have happened here. gemm.c basically just includes other files and the error message makes it hard to determine which line could not be interpreted. Could you try building from a snapshot of the current develop branch rather than 0.2.20 to see if it is something that was incidentally fixed in the meantime ?

[witignite]

Still have the same error. Also, I haven't mentioned that it had 2 warnings during the compilation (if it matters).

I really have no idea, maybe the problem with the compiler? So basically, I installed MinGW from the above site and just installed mingw64, msys, gcc, and gfortran package using pacman -S command. Should I try with another compiler?

[martin-frbg]

Maybe try an older version of the mingw gcc.

[nikudyshko]

Had the same <command-line>:0:4: error: expected identifier or '(' before numeric constant error.

Following steps helped me:

1. Reinstall MSYS2, update it.
2. In MSYS2-shell:
   pacman -S make - installs make util.
   pacman -S gcc-fortran - installs gfortran together with gcc and all needed. By default provides older 6.4.0 version.
   pacman -S perl - installs Perl (required for build process).

After that I was able to build library, though got strange linking-error at the very begin and a bunch of warnings during build process

[martin-frbg]

Thank you very much for that feedback, I have updated the wiki page accordingly (I hope).

[Draino23]

Please correct me if I am wrong, but doesn't @nikudyshko instructions link in the MSYS2 library and not create a native windows binary? I believe the MinGW compiler must be used, in which case I am getting the same error that @wittgithub was getting.

[martin-frbg]

I do not understand your comment about "believe the MinGW compiler must be used" - msys2 alone (without the pacman -S gcc) does not provide a compiler, or does it ?

[Draino23]

The standard MSYS2 subsystem alone does not provide a compiler, but one can be added using pacman as you described. I believe the one added through pacman -S gcc is not the MinGW compiler, but one specific to the MSYS2 subsystem. For native windows programs the mingw32 or mingw64 subsystems should be used (pacman -S mingw-w64-i686-toolchain or pacman -S mingw-w64-x86_64-toolchain).

Here is a page I found with more info about the subsystems:
https://github.com/msys2/msys2/wiki/MSYS2-introduction

[martin-frbg]

So the instructions in the wiki should be for mingw-w64-gcc-fortran rather than gcc-fortran... and if that is expected to produce more windows-like binaries perhaps it pulls in a windows10 header that contains some confliction declaration of a variable or similar.
Unfortunately the error location of <command line>:0:4 is not likely to help track this down.

[martin-frbg]

I have reverted my wiki change now.

[nikudyshko]

Unfortunately, @Draino23 has right - dynamic library indeed links with some msys2 dll-s. I didn't realized it in time becouse I use static OpenBLAS lib, which works fine for me. But of course, it's better to find another way to build library. My apologies.

[martin-frbg]

The offending file (driver/level3/gemm.c) boils down to

#include <stdio.h>
#include "common.h"
#include "level3.c"

if the problem was with the actual header files, it should have occured earlier. So this seems to leave level3.c itself which starts with lots of macro definitions. The last change of that file removed a number of seemingly unnnecessary parentheses, but that happened months after 0.2.20 was released (which seems to be what at least wittgithub was building) so probably unrelated.
Perhaps if you tried to invoke the mingw-gcc on level3.c directly, it would be able to give a better location for the error ?
(Searching for the message brought up mingw bug 2183, where definitions from the gcc command line were applied case-insensitive. so could clash with lowercase variable names in the code. But that was supposedly fixed with their version of gcc 4.8.2)

[nikudyshko]

@martin-frbg So, I've tried to invoke mingw-gcc (7.3.0) on level3.c and got the following:
Desktop\OpenBLAS\driver\level3>gcc level3.c
level3.c:172:11: error: unknown type name 'blas_arg_t'

Update 1: got the same errors with command line gcc -m64 -I../.. -DCR ../../param.h gemm.c level3.c
Update 2: added #include "common.h to level3.c-file and run gcc -O2 -m64 -I../.. -c -DCR level3.c -o lev.obj and it has been successfully executed without any error. I have no idea what's wrong...

After that I decided to try direct execution of this single line
gcc -O2 -DMS_ABI -DMAX_STACK_ALLOC=2048 -Wall -m64 -DF_INTERFACE_GFORT -DSMP_SERVER -DNO_WARMUP -DMAX_CPU_NUMBER=4 -DASMNAME=cgemm_cr -DASMFNAME=cgemm_cr_ -DNAME=cgemm_cr_ -DCNAME=cgemm_cr -DCHAR_NAME=\"cgemm_cr_\" -DCHAR_CNAME=\"cgemm_cr\" -DNO_AFFINITY -I../.. -UDOUBLE -DCOMPLEX -c -UDOUBLE -DCOMPLEX -DCR gemm.c -o cgemm_cr.obj
and it has been successfully executed without any error

[martin-frbg]

@rathaROG how did you build it ? If it is a pure VS build, performance will probably be not optimal as the Microsoft tools cannot handle the assembly kernels.

[rathaROG]

@martin-frbg yes it is pure VS an it does not include all like lapacke & cblas.. that's why I deleted my previous comment. My apology.

[Draino23]

So, I now have been able to build OpenBlas 2.20 using mingw-64 (x86_64-7.3.0-posix-seg-rt_v5-rev0) that I installed using the online installer from source forge (https://sourceforge.net/projects/mingw-w64/).

I am using the MSYS subsystem base (so no gcc in in PATH) with make and perl installed through pacman, and then add the new mingw-64 bin directory to PATH. Then I am able to make with no errors. I also had it work with the gcc 6.3 version from the sourceforge installer.

Perhaps something is wrong with the gcc installed through pacman in MSYS2?

[rathaROG]

By the way, I built with mingw & msys, and there was no problem so far.

I shared my* binary package here if anyone is interested in.

[kernhanda]

@rathaROG, could you detail the steps you used? Were they different from what's on the wiki?

[nikudyshko]

Finaly built this lib (with gcc 7.3.0). I used the way, similar to @Draino23 described. The main point is to install mingw64 with original installation file from sourceforge but not via pacman.

[rathaROG]

@kernhanda I just followed the wiki. It's simple like that.

This is how I did it:

• download these two packages: mingw & msys.
• extract to anywhere and set 3 environment variables (\mingw\bin, \msys, \msys\bin).
• open cmd, run msys, and in msys terminal, navigate into your OpenBLAS folder and finally, run make.

[martin-frbg]

@ratharog so you used the msys and mingw from sourceforge (original mingw-w64 project I think), not the msys2 from msys2.org that is currently suggested in the wiki ? It seems the switch from one to the other was made in early january by xoviat so the implication is that it should have worked at that point. (Seems that account no longer exists unfortunately, so not possible to ask directly)

[rathaROG]

@martin-frbg there are many update revisions for the instruction lately... and yes, you're correct that I use the original mingw & msys. Since I'm happy with the original mingw & msys and they never bother me, I have never tried that msys2 from msys2.org.

[martin-frbg]

I know about the revisions (and I am guilty of some of them myself), that is where I found out when msys2.org was introduced. (I think this was also discussed in an issue or PR at the time, but cannot seem to find it).

[martin-frbg]

Reproducible with Win10, msys2 from msys2.org and pacman installation of mingw-w64-x86_64_gcc, the causal factor appears to be the -DCR (though -DNR, which maps to the same ifdefs in the .c file works fine)

[martin-frbg]

This indeed looks as if mingw bug 2183 (as I mentioned earlier) either was never fixed in the branch used by the msys2 folks, or it somehow reappeared: If I change all the "CR" to "CRX" both in the level3 Makefile and in the files that have "if defined(CR)", the build completes without further issues.

[martin-frbg]

I have now changed the wiki page to (again) recommend getting mingw-w64 from sourceforge.net, and have added a note about the problem with the version from msys2/pacman.

[econwang]

For those who use something like pacman -S mingw-w64-x86_64-toolchain to install gcc, please downgrade mingw-w64-x86_64-crt-git, mingw-w64-x86_64-headers-git, and mingw-w64-x86_64-tools-git by (assume x64):

pacman -U mingw-w64-x86_64-crt-git-6.0.0.5100.739199f8-1-any.pkg.tar.xz

pacman -U mingw-w64-x86_64-headers-git-6.0.0.5102.2f16a8c7-1-any.pkg.tar.xz

pacman -U mingw-w64-x86_64-tools-git-6.0.0.5079.3b7a42fd-1-any.pkg.tar.xz

All packages can be downloaded from http://repo.msys2.org/

[martin-frbg]

So is/was this a known problem in recent msys2 toolchains @econwang, or did you happen to know from experience that building with that particular version worked before ? In any case I have updated the wiki page with that information now, thank you very much.

[econwang]

This is the most recent version I have tested with gcc version 7.3.0 (Rev1, Built by MSYS2 project) @martin-frbg

[martin-frbg]

Just trying to gather some information that would allow the msys2 folks to fix the underlying problem, I must admit I do not know the mingw code layout (as compared to gcc on Linux). crt is probably the runtime library (equivalent of libc.so), headers sounds like just that, so that would leave only something in the "tools" package as the culprit if the core gcc 7.3.0 itself works ?

[martin-frbg]

From the msys2 issue ticket, this problem appears to have been introduced only very recently - probably at most four weeks before the start of this issue thread.

[hsntgm]

Sure first go /var/cache/pacman/pkg/ and download these packets from the http://repo.msys2.org/ to this folder.Then you can downgrade with pacman -U

For those who use something like pacman -S mingw-w64-x86_64-toolchain to install gcc, please downgrade mingw-w64-x86_64-crt-git, mingw-w64-x86_64-headers-git, and mingw-w64-x86_64-tools-git by (assume x64):

[Neiko2002]

Had the same problem with MinGW from msys2.org and can confirm the steps from @hsntgm and @econwang work.

[pingplug]

The same problem in Arch Linux with mingw-w64-headers-git.
This problem seems start from this commit in mingw-w64 https://sourceforge.net/p/mingw-w64/mingw-w64/ci/0f9569488ba7e48472183765a7ae6555ed990f4a

[martin-frbg]

Thank you for tracking down this commit, I admit I was not even sure which tree msys2 was pulling from.
struct _IMAGE_ARM64_RUNTIME_FUNCTION_ENTRY near the end of that commit at least defines a dword CR that appears to be clashing with OpenBLAS' -DCR. Now are these clashes between compiler-specific headers and user code expected on Windows (seems like everybody using latin alphabet would run out of identifiers fast if that were the case), or did the header change just precipitate a pre-existing problem in a parser ?

[martin-frbg]

That struct actually seems to originate from the Windows10 winnt.h, still not sure if it should legitimately clash with our #define (and if so, why this did not come up with VS or clang on Windows).

[pingplug]

workaround: use -DCR=CR to define CR and leave 'CR' in weinnt.h untouched

[martin-frbg]

Thanks. If this turns out to be a real OS header clash (even if forced on us by the OS vendor), it might make sense to rename the OpenBLAS parameters to something like OB_NN,...,OB_CR,...,OB_RR to reduce the risk of further conflicts.

[scarsty]

at winnt.h line 7241:
DWORD CR : 2;
but the macro -DCR in the commandline make this wrong .

Maybe you can edit Makefile in driver/level3, replace -DCR into -DCR=CR as pingplug suggested, then it work.
Clang can track it but gcc cannot.
