Compilation error

[ShevaDavid]

When I run make

rm -f xoop
cc -Wall -Wextra -pedantic -lxcb -lxcb-randr -lxcb-xinput -lxcb-xfixes xoop.c -o xoop
xoop.c:27:10: fatal error: xcb/randr.h: No such file or directory
27 | #include <xcb/randr.h>
| ^~~~~~~~~~~~~
compilation terminated.
make: *** [: xoop] Error 1

Hey, it looks like you don't have the XCB headers installed. You'll need the dev version of your distro's XCB library

…

Hi!

I installed the required libraries and still got compilation errors:

$ make

This is due to the Makefile itself: The libaries are included in CFLAGS, but they should be listed in LDLIBS. The order of the parameters for cc matters, and as you can see in the cc -Wall -Werror ... line above, the libraries are listed before xoop.c, but would need to be listed after xoop.c .

@m-col I'll send you a PR 🙂
Edit: Here it is: #4

And of course, thank you for this amazing tool!
