Hi @ezadEzanee

this looks like a simple problem. The compiler can not link against X11

ld: library not found for -lX11

i do not have a mac os to test this on, but i'll try to get back to you as soon as possible. did you look on stackoverflow for -lX11 issue with osx? i found this thread that seems to solve the problem at least for one user

Hi @mherkazandjian ,

I have resolved the error above. After running the install command again, I'm faced with another error.

clang -bundle -undefined dynamic_lookup -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk -L/opt/X11/lib -I/usr/local/include build/temp.macosx-10.14-x86_64-3.7/fastgrab/linux_x11/screenshot.o -lX11 -lgomp -o build/lib.macosx-10.14-x86_64-3.7/fastgrab/_linux_x11.cpython-37m-darwin.so
ld: library not found for -lgomp
clang: error: linker command failed with exit code 1 (use -v to see invocation)
error: command 'clang' failed with exit status 1

I have libomp and llvm installed in my environment. Are you running openmp? I see some lines commented out in screenshot.c and setup.py. I tried removing gomp from the library and the installation managed to proceed however tox output shows the following

hi @ezadEzanee

i also had been having trouble with the venv thing with tox. i decided to ditch it.
I moved the CI to circle CI too and i updated the readme with the minimal testing instructions without
using tox. The python py36 seems to be related to tox and venvs, not to this repo or the tox config file. Please re-test with the instruction in this branch

[dylanzenner]

has this been fixed yet? I am having this issue when trying to install on:
MacOS 11.2.3
python 3.9
