I'm trying to build a debuggable cc1plus using "http://gcc.gnu.org/wiki/DebuggingGCC"/"Building a Debuggable Compiler" section. Should: [make STAGE1_CFLAGS="-g3 -O0 -save-temps" all-stage1] build cc1plus? or is this just for cc1? I don't see any errors at the bottom, but a search finds no cc1plus. (The -save-temps is added here because the page says "Assuming you've produced preprocessed source). I'm using: [configure --prefix=/make/gcc/ses/out --program-suffix=-ses] GCC = 4.3.2 host/build = x86-64-unknown-linux-gnu ubuntu = 8.04 (Hardy) Thanks for all assistance. Simon.
