Undefined reference to timersub while compiling darknet #10

Closed Bosi1024 closed 2 years ago

Bosi1024 commented 2 years ago

Hi again,

I'm trying to compile darknet which gives an undefined reference to timersub while linking at the end.

mingw64/bin/../lib/gcc/x86_64-w64-mingw32/12.2.1/../../../../x86_64-w64-mingw32/bin/ld.exe: CMakeFiles\darknet.dir/objects.a(classifier.c.obj):classifier.c:(.text+0x572c): undefined reference to 'timersub'

If this is an upstream issue I will gladly report it upstream.

Kind regards

Where does timersub come from? I couldn't find this thing in mingw-w64 so I suspect it's defined by Darknet itself?

Looks like this is a function on Linux,. However mingw-w64 apparently doesn't provide it, so if code uses it then it's almost always due to misconfiguration.

That seems to be the case. I'll take this issue to the Darknet developers.
