Can't compile

Hi, I am trying to compile touchcursor but I get the following error:

I am on azerty, debian and sway. Tell me if you need more info.

(note that this is not a duplicate of #35)

Hello @anakojm, from what I've read, you need to add -pthread to the gcc options in the Makefile.

diff --git a/Makefile b/Makefile

 # All .c files, excluding test.c

I'm not sure why it worked before for me and others, but it doesn't seem to hurt anything to have that flag present. I've updated the make file if you would like to simply git pull.

I pulled but I am still getting the same error, even with the pthread flag

I found a patch that work that I'll submit in a PR

Nice catch. #65 has been merged.
