Error when installing on windows: "cannot find -lpthread"

[andresantacruz]

I'm following this link ( https://radare.gitbooks.io/radare2book/content/introduction/windows_compilation.html#mingw32 ) and calling sys/mingw32.bat. After some time compiling, I get the error output bellow.

c:/mingw/bin/../lib/gcc/mingw32/6.3.0/../../../../mingw32/bin/ld.exe: cannot find -lpthread collect2.exe: error: ld returned 1 exit status make[2]: [libr2.dll] Error 1 make[2]: Leaving directory `/d/OSDefault/Documents/RCETools/radare2/binr/preload' make[1]: [preload] Error 2 make[1]: Leaving directory `/d/OSDefault/Documents/RCETools/radare2/binr' make: *** [all] Error 2

I don't know much about linux way of doing things so I'm probably messing something simple.

As I didn't find which specific binaries I should get from mingw, I installed some basic ones (gcc, zip, etc). Could it be some missing mingw executable?

Oh, as the compilation output goes frantically I can see a lot of warnings on code, is that expected in a right environment?

Thanks.

Additional info I found in the output that may be useful (I think it's the output from ./configure file):

I'm not very familiar with mingw, but you need pthread libraries. Make sure it is installed, it should be named pthread-win32 or something like this.

[xarkes]

Also please note that you can find precompiled binaries here: http://radare.mikelloc.com/get/2.0.1/ radare2-w are compiled with mingw, and radare2-msvc- are obvisouly compiled with msvc

[andresantacruz]

Thanks for the reply @xarkes I didnt know about this radare repository, will check it out soon.

I'll try and get the pthread-w32 to see if it fix the problem.

About the warning messages though, you know if it's expected?

[xarkes]

Yes it is hard to maintain code that do not generate any warning on every platform, so this is expected.

[andresantacruz]

I downloaded the pthread-w32 as you told and the compilation works. Thanks again.

Thanks guys from 2017 :D
