Re: failed building gcc 4.6 from sources on linux mint 2.6.35-28-generic, when doing Fortran build

See this FAQ:

As stated in the installation instructions at
gcc.gnu.org/install/configure.html you should not run ./configure, you
should build GCC in a different directory from the one containing the
sources.
humm... Ok, will revisit everything then. I am just following the
standard method of building any linux software: unpack tar, cd to the
folder created, type ./configure; make; make install.
You're looking in the wrong file.
As the FAQ says, the usual reason is that the runtime linker can't
find the prerequisite libraries (which is also stated in the
--with-gmp docs at http://gcc.gnu.org/install/configure.html - you
should read that too.)
Well, But I was following the instructions here:
http://gcc.gnu.org/wiki/FAQ
item 5, where it says:
"You have to check the file 'config.log' in the directory where the
error occurred (denoted by Entering/Leaving directory)."
And they gave an example. And in my case, such directory was:
" make[2]: Leaving directory
`/media/sf_nabbasi/data/Fortran_related/gcc_4_6/gcc-4.6.0'
"
And that is the config.log file I was looking at.
So, you see, I was just following the instructions, and did read it :)
You could try using the makefile linked to at
http://advogato.org/person/redi/diary/229.html which makes building
gcc much easier (especially if you don't read the documentation about
ensuring libgmp.so etc. can be found by the runtime linker)
Thanks, will try it.
I've uploaded the correct config.log file now here
http://12000.org/tmp/march_27_2011/
and called it libgcc_config.log
I see now the errors:
