FreeBSD incompatbility error during linking in libr/rules.mk to previously built libr/util/libr_util.so (xref: LINKFLAGS+=../../util/libr_util.a) during rax2 compilation.

Additional:

linux is unaffected, obviously.

Workaround:

Use previous build

Afair he said he already fixed it. @unixfreaxjp have you tried very latest version of the sources?

Thank you for the response, latest built 695d9a0..50a46a9 was used, please see: https://github.com/unixfreaxjp/dev/blob/master/r2freebsdi686.md

unixfreaxjp on 16 May 2016

@unixfreaxjp try with this one https://github.com/radare/radare2/commit/49912c0226ec37178934d0be7421a4849d4f02e3

XVilka on 16 May 2016

@unixfreaxjp try with this one 49912c0

Thank you. The built https://github.com/radare/radare2/commit/49912c0226ec37178934d0be7421a4849d4f02e3 was tested.
Build result: https://github.com/unixfreaxjp/dev/blob/master/r2freebsdi686-2.md OK.

Do not use backtrace if it's not available xref: https://github.com/radare/radare2/commit/49912c0226ec37178934d0be7421a4849d4f02e3

Question: So we can't backtrace in FreeBSD?

Thank you for the fix, the compilation is much more important than backtracefeature, since this issue is for build error, I am closing it.

unixfreaxjp on 16 May 2016

Well, we can, but we'll need to figure out right way. It requires libexecinfo, so r2 buildsystem should check its presence.

XVilka on 16 May 2016

It requires libexecinfo,

libexecinfo was installed from /usr/ports.

$ pkg info libexecinfo

Description    :
This is a quick-n-dirty BSD licensed clone of backtrace facility found
in the GNU libc, mainly intended for porting Linuxish code to BSD
platforms, however it can be used at any platform which has a gcc
compiler.

WWW: http://www.gnu.org/software/libc/manual/html_node/Backtraces.html

Yet, it still failed in the build with same error, could be more than just detecting libexecinfoexists? no? :

../rules.mk:73: recipe for target 'rax2' failed
gmake[2]: *** [rax2] Error 1
Makefile:14: recipe for target 'all' failed
gmake[1]: *** [all] Error 1
Makefile:47: recipe for target 'all' failed
gmake: *** [all] Error 2

in this build:

$ git describe --all --long
heads/master-0-g50a46a9

I am keeping old and new https://github.com/radare/radare2/commit/49912c0226ec37178934d0be7421a4849d4f02e3 fix ones for trouble shooting..

Dammit guys, i sent this PR and you ignored it :( #4899

@dequis lol, sorry, haven't noticed it. Will reuse your approach.

Hey, that #ifdef is a nice approach! https://github.com/radare/radare2/pull/4899/commits/0afe75258b6e59b1dff8f89b41972904fb71814e
So, which one to use? the https://github.com/radare/radare2/commit/49912c0226ec37178934d0be7421a4849d4f02e3 or https://github.com/radare/radare2/pull/4899/commits/0afe75258b6e59b1dff8f89b41972904fb71814e ?

@dequis @XVilka

unixfreaxjp on 16 May 2016

All in the tree. Should be fixed for now. As for backtrace support in FreeBSD - I've created another issue.

Explanation:
This bug in compilation was fixed by @dequis @XVilka and I was testing it and now using the build, here is fix explanation.
Not much usingbacktraceanyway. So I can patiently look forward for @XVilka backtrace on BSD systems issue #4910 follow ups. Just for the notes, even libexecinfo installed I received same error..
