Gcc compilation “cannot compute suffix of object files: cannot compile”

Question

I\'m actually reading the LFS book (version 7.1) and I\'m blocked at page 53. Trying to compile gcc, I tried the following command:

./configure --target=$LFS_TGT         


        

Answer 1

This issue is caused by dyanmic link library path issue when the test programs try to link against libmpc/libmpfr/libgmp.

Append below environment variable to allow ld link against the correct so file:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/mpc/lib/

Then try build gcc again.
