What do you recommend in that case?
If this is a compiler for normal use rather than for bootstrapping only, it's broken if it doesn't have these functions in some form of libgcc. > (If you don't build gcc with --disable-shared, you need a libc.so to link > libgcc_s.so against before you've built a compiler with which to build that > libc.so. Chicken and egg problem.) If it's a bootstrapping issue, use the --disable-shared compiler only to build crt*.o, install those and the uClibc headers, build a dummy libc.so with -nostdlib -nostartfiles, and that suffices for the second compiler to build libgcc_s.so that suffices to build uClibc. -- Joseph S.
