gcc 4: no specs file

rconan · 07-07-2005, 03:39 PM

The first thing to say is that im not actually running LFS, hence GCC 4!

I have compiled and install GCC4 and have reached the equivalent to step 5.7 adjusting the toolchain.
However I cannot edit my specs file as I have read that GCC 4 does not install one.

Any alternative method for GCC 4 or way to make a spec file for GCC 4

You should dump specs into specs file (ex: /tools/lib/gcc/.../specs) first:

Code:

# gcc -dumpspecs > /path/to/file

will that then cause the compiler to use that file instead of the integrated specs.

You could try it yourself

when i do:
gcc --print-file specs
I get:
/mnt/LFS/tools/bin/../lib/gcc/i686-pc-linux-gnu/4.0.0/specs
so i presume it is now using that file as specs.

Yeah, congratulations and dont forget to tell me successful story of your gcc-4 base LFS installation when you done

Cheers,

OK so now im installing GCC for the system instead of the toolchain and need to prevent GCC from installing libiberty cos the binutils one is more recent (therefore i presume the one i want).

Will the same SED script work?
