Can anyone share fasm sources of Linux GUI based on different graphic *so (glut,xlib,..)? (maybe glut & xlib of them is enough, because others are appendix over xlib?)

or maybe so:

Can anyone compile examples from source and than share link to binaries?
I will disassemle them and than place here fasm sources

thanks in advance.

previously i replace display with displ in too many places. fixed. (in source & in archive)
now it looks like it should work. still not tested. I have only x64 Linux VM for now. Soon download x32, & will make fixies if they needed.
