[Bug]: igraph cant be installed with pip
Problem description
If you download termux from fdroid, install pip, python-cmake, cmake etc and then run pip install igraph it fails due to -lgcc not being available to the linker. Maybe a gcc package should be added to Termux? Here is the full logs.

note: This error originates from a subprocess, and is likely not a problem with pip. ERROR: Failed to build 'igraph' when installing build dependencies for igraph
What steps will reproduce the bug?
pip install igraph But you have to have pip, python-cmake and cmake installed
What is the expected behavior?
No response
System information
Termux(fdroid version)
Try this
pip install --no-build-isolation --no-cache-dir igraph
and try again. that works for me
ld.lld: error: unable to find library -lgcc
There is a way to work around that error temporarily if it ever happens for you for something else, for some reason it's this:
echo 'INPUT(-lc)' > $PREFIX/lib/libgcc.so
however in this case, the above other commands worked instead, so that wasn't necessary for me. I don't know if that workaround is a good way or not for packaging in ndk-sysroot.
If you download termux from fdroid, install pip, python-cmake, cmake etc and then run pip install igraph it fails due to -lgcc not being available to the linker. Maybe a gcc package should be added to Termux?
You shouldn't need GCC specifically, Clang/LLVM should work just as well.
And clang++ is getting correctly picked up.

There is also a gcc package available from the TUR.
But you shouldn't need it for this.
Robert's suggestion might work though
To be specific with the explanation, this error occurs with some Python packages with no arguments to pip, because something attempts to build a CMake as a build dependency of other things, and this command avoids that for me and results in successful installation of igraph
pip install --no-build-isolation --no-cache-dir igraph
Robert's solution worked after first running pip install setuptools. You are right that GCC shoun't be needed with clang present but it looks like the linker specifically tried to link against gcc with -lgcc.
it looks like the linker specifically tried to link against gcc with -lgcc.
well, that error you see is a difference I am aware of between the cross-compiler and the non-cross-compiler because the cross-compiler does contain a 64-bit ARM Android Clang version of a libgcc.a without actually being GCC so during cross-compilation of any packages of software that uses that linker argument, nothing goes wrong, but for some reason the non-cross-compiler doesn't have any libgcc.a or libgcc.so, so if it happens to you in the future again and is annoying then you can try the other workaround I showed which worked for me for something else
I forgot, the cross-compiler's libgcc.a is actually this so it's an INPUT(-lunwind) not an INPUT(-lc),
builder@dc7513f1f83a:~/termux-packages$ cat /home/builder/.termux-build/_cache/android-r28c-api-24-v2/sysroot/usr/lib/aarch64-linux-android/libgcc.a
INPUT(-lunwind)
builder@dc7513f1f83a:~/termux-packages$
but to be honest I never really knew why it's not provided in ndk-sysroot in this area, and I thought there might be some reason why it's not, so I just didn't mess with it
