Re: [Fish-users] `` vs ()
On Fedraa 25, this works fine: gcc (pkg-config --cflags gtk+-3.0 | string split ' ') (pkg-config --libs gtk+-3.0 | string split ' ') On RHEL 6.7 this was required: gcc (*pkg-config --cflags gtk+-2.0 |* string trim | string split ' ') (pkg-config --libs gtk+-2.0 | string trim | string split ' ') ---for whatever reason "pkg-config --cflags gtk+-2.0" adds space at the end?
