Radare2: Unable Detect Clang Compiler in MacOS

[SajjadPourali]

Hi,
When building librz.a clang has an error, I didn't yet check why it's happened.

It seems problem is related to build script, it can not detect compiler is clang.

[radare]

is this r2 from git? are you using sys/install.sh ? otherwise just make a clean clone and do that. you probably have a trashed builddir, you can also git clean -xdf

[radare]

Did you git clean -xdf. Sounds to me like you have upgraded xcode and the builddir have still object files created with the old one

[ZhangZhuoSJTU]

I think I have done git clean -xdf, but it failed. I also cloned the repo in a new directory, same error occurred.

[radare]

The real error here is in

[radare]

I have also seen warnings that are fixed in master.. and cant repro yet..

[SajjadPourali]

I have also seen warnings that are fixed in master.. and cant repro yet..

It can be fix by using libtool -static instead of ar q command.

[ZhangZhuoSJTU]

@SajjadPourali A quick question. May I know which place you have edited to make clang work? I tried but failed these days. :(

[radare]

I still cant reproduce this issue and i have tested in several machines and environmwnts

Could you please let me know which commit fixed these warnings? This might help me debug about why building failed on my machine. Thanks a lot.

[SajjadPourali]

@ZhangZhuoSJTU : I did attach my changes, it's dirty fix but it works.
my changes : radare-fixed.tar.gz

sorry, I didn't create patch file, because I'm sleepy and capstone needs patch too, it take a little bit time.

[sferrini]

@SajjadPourali and @ZhangZhuoSJTU are you using binutils from brew (_Check with brew list | grep binutils_)?

I solved uninstalling it and just using binutils from Xcode (default).

[SajjadPourali]

@sferrini : Thank you,I did unlink binutils and it works.
I think when I did update binutils to 2.31.1, this problem appears.
