Not "if"
"when" because we're gonna get this built buddy
Meant If you can host it on your Google drive like you did the picture and share the link as I have an arm device and would like to test it, but not able to compile like you are.
All that said your issue seems to be a complicated one, have a lot of ideas here and trying to sort out the correct one.
Honestly that function in the os_x11.cpp
file does not look that important and would just void it to null (x11 has to do with window management)
Also thinking it could be a change in the linker
Or the order in which the libraries are linked
Hmm.. ok first try building without multiple cores
scons platform=x11 target=release_debug
Should not take long with everything already built then if it still fails try as it says adding the -fPIC
flag instead of fpic
