[deionizedoatmeal]

I've been struggling with this issue on my arch system. My workaround was to use Clang as the compiler instead of GCC and then everything built and installed fine.

I don't really know much C so I really have no idea why this would be the case. Maybe it has something to do with GCC not fully supporting the C99 standard, but don't quote me on that.

Anyways the way I did this just to install clang, then change my environment variables:

export CC=/usr/bin/clang
export CXX=/usr/bin/clang++

and then build from source as you would normally with i3.

Hope this helps.

[dunestorm333]

Same problem, can't build.

@deionizedoatmeal Unfortunately your suggestion doesn't work as I get:

configure: error: C compiler cannot create executables

[Syycorax]

Same problem :/ As @dunestorm333 The workaround don't work for me, get this export CXX=/usr/bin/clang++

[Nycz-lab]

same problem however when i use clang i get "linker command failed with exit code 1" if anyone has a solution pls msg me

[pellizzetti]

Setting GCC environment variables as such solved it for me:

export CPPFLAGS="-U_FORTIFY_SOURCE"
export CFLAGS=" -fcommon"

Works for me ^^
