I'm writing some C code using the X11 API, and want to use the function XTestFakeButtonEvent.
According to the docs I'd need to include <X11/extensions/XTest.h>.
I had to install libXtst-devel to be able to include it.
However, when I compile I still get this error:
/usr/lib64/gcc/x86_64-suse-linux/13/../../../../x86_64-suse-linux/bin/ld: /tmp/cc4pbNhk.o: in function `main':
mouse-chording.c:(.text+0x7bf): undefined reference to `XTestFakeButtonEvent'
collect2: error: ld returned 1 exit status
Is libXtst-devel not the right package?
I compile with the following command:
gcc mouse-chording.c -o mouse-chording.exe -lX11
#include "X11/Xlib.h" was not enough, appearently, I also needed to add -lX11 to the compilation command.
Do I have to do something similar for XTest?
Using OpenSUSE Tumbleweed with XFCE.
Checked what xdotool does, since it is using the same library.
The Makefile has -lXtst so I added this to the make command and it works.
The inconsistency in naming is kind of confusing though; XTest, libXtst, and lXtst
