I'm interested in working on the Rust front-end for GCC. So far I've cloned the repository <https://github.com/redbrain/gccrs.git> and tried to compile it as described in <https://gcc.gnu.org/wiki/RustFrontEnd>. I've compiled it outside of the gcc directory tree with
$ ../gccrs/configure --prefix=/opt/gccrs --enable-languages=rust --disable-multilib --disable-bootstrap $ make But this produces some linking errors for functions that were called but never defined: /usr/bin/ld: rust/rust-lang.o: in function `rust_langhook_handle_option(unsigned long, char const*, long, int, unsigned int, cl_option_handlers const*)': /home/baal/gccrs-build/gcc/../../gccrs/gcc/rust/rust-lang.c:185: undefined reference to `rust_add_search_path(char const*)' /usr/bin/ld: /home/baal/gccrs-build/gcc/../../gccrs/gcc/rust/rust-lang.c:213: undefined reference to `rust_add_search_path(char const*)' /usr/bin/ld: /home/baal/gccrs-build/gcc/../../gccrs/gcc/rust/rust-lang.c:217: undefined reference to `rust_add_search_path(char const*)' /usr/bin/ld: rust/rust-lang.o: in function `rust_langhook_post_options': /home/baal/gccrs-build/gcc/../../gccrs/gcc/rust/rust-lang.c:245: undefined reference to `rust_add_search_path(char const*)' /usr/bin/ld: rust/rust-lang.o: in function `rust_langhook_parse_file()': /home/baal/gccrs-build/gcc/../../gccrs/gcc/rust/rust-lang.c:282: undefined reference to `rust_parse_input_files(char const**, unsigned int, bool)' /usr/bin/ld: rust/rust-lang.o:/home/baal/gccrs-build/gcc/./gtype-rust.h:24: undefined reference to `rust_non_zero_struct' collect2: error: ld returned 1 exit status make[2]: *** [../../gccrs/gcc/rust/Make-lang.in:61: rust1] Error 1 make[2]: Leaving directory '/home/baal/gccrs-build/gcc' make[1]: *** [Makefile:4319: all-gcc] Error 2 It's doesn't really help that the latest commit message (3b1e76d808b9725e6ef439ae534011370e65fb85) says simply "x" and the previous one, only "more". Anyhow, I'm left with those questions: - Considering I'm new to gcc development, what should I read before getting into this? - Is there any developer in particular I should talk to? - Is there anything else I need to know before getting started?
