Compilation problem

[c00kiemon5ter]

hmm, I cannot see any reason for these errors.
Are you sure the code is clean and not tampered?

The following should just work:

git clone https://github.com/c00kiemon5ter/iim.git iim-test
cd iim-test
make iim CFLAGS="-std=c99 -Os -Wall -Wextra -pedantic"

you can also check with clang using
(I made a small change today, to keep latest clang happy)

make iim CC="clang" CFLAGS="-std=c99 -Os -Wall -Wextra -pedantic"

If this works, you should have an executable named iim.
If this goes well, then I guess the (AUR) package is faulty.

Try this and tell me if I need to look into it further.

Thanks ;)

make: *** [<builtin>: iim] Error 1

[c00kiemon5ter]

The easy workaround is to #define _GNU_SOURCE instead of #define _POSIX_SOURCE
or try it in the command line with

make iim CFLAGS="-D_GNU_SOURCE -std=c99 -Os -Wall -Wextra -pedantic"

(notice the -D_GNU_SOURCE part)

That should fix it for now - I'll look into it further, later.

Thanks! Can confirm this resolves the issue.

Thank you for creating iim too. I really enjoy using it!
