Hi Guix, with the release of Emacs 28.1, there has been some demand to enable native-compilation. While trying to set that up, I've come to realize that no matter how I slice it, I can't make libgccjit usable.
My test: $ cd /tmp $ # fetch the "Hello World" [1] and insert it into gccjit-test.c $ guix shell --pure gcc-toolchain@9 libgccjit@9 -- \ gcc gccjit-test.c -o gccjit-test -lgccjit $ ./gccjit-test x86_64-unknown-linux-gnu-gcc-9.4.0: fatal error: cannot execute 'as': execvp: No such file or directory compilation terminated. Welp, okay, so maybe testing gccjit outside of its installation does not work. What if we try it inside the shell (we can always propagate libgccjit, no?) guix shell gcc-toolchain@9 libgccjit@9 -- ./gccjit-test ld: cannot find crtbeginS.o: Datei oder Verzeichnis nicht gefunden ld: cannot find -lgcc ld: cannot find -lgcc collect2: Fehler: ld gab 1 als Ende-Status zurück libgccjit.so: error: error invoking gcc driver NULL result For the record, Emacs 28 fails with a different error during configuration, though interestingly they use a smaller program and appear to omit -lgccjit. ./conftest: error while loading shared libraries: libgccjit.so.0: cannot open shared object file: No such file or directory I'm at a loss. Is there any way to make libgccjit actually usable? [1] https://gcc.gnu.org/onlinedocs/jit/intro/tutorial01.html
