Gfortran compile error
 

When I tried to compile gcc with fortran enable:

make[3]: Entering directory `/data/gcc-build/i686-pc-linux-gnu/libgfortran'

Why?:confused:

which chapter?
gcc is compiled 3 times per LFS-6.2 instructions!

No. I had compiled gcc before. Now I want to upgrade it (With gfortran) to the newest svn version.

Just like BLFS:
