Hi Thomas
Thank you! I got part of the way there after discovering that
download-prerequisites had to be download_prerequisites, but make -j12
had a fatal error. What I did was
$ cd
% mkdir Gcc
% cd ~/Gcc
$ tar xvjf ../Downloads/gmp-6.2.1.tar.bz2
$ tar -zxvf ../Downloads/mpc-1.2.1.tar.gz
$ tar xvjf ../Downloads/mpfr-4.1.0.tar.bz2
$ tar -x -f ../Downloads/gcc-14.2.0.tar
$ cd gcc-14.2.0
$ contrib/download_prerequisites
$ cd
$ mkdir Gcc-build
$ cd Gcc-build
$ ../Gcc/gcc-14.2.0/configure --prefix=$HOME --enable-multilib
--enable-languages=c,c++,fortran
$ make -j12
After several minutes of checking and compilation, that ended with
In file included from
../../../../Gcc/gcc-14.2.0/libgcc/../gcc/tsystem.h:95,
from ../../../../Gcc/gcc-14.2.0/libgcc/libgcov.h:42,
from
../../../../Gcc/gcc-14.2.0/libgcc/libgcov-merge.c:26:

That error message is puzzling because the offending file seems to exist:
(lf) john:~/Gcc-build$ ls -l /usr/*/*/bits/libc*
-rw-r--r-- 1 root root 4286 May 7 08:34
/usr/include/x86_64-linux-gnu/bits/libc-header-start.h
(I know Fortran much better than bash and make)

Hi John,
Thank you Damian. Tried the first suggestion. It said I already had
gfortran; it turned out to be version 13. Tried the second suggestion.
My system has not heard of git. Managed to find gcc-14.2.0.tar so I am
now struggling to do something with that.
Assuming you have the top level of the gcc sources (where the configure
script resides) in the ~/Gcc directory, you can do the following:
$ cd ~/Gcc
$ contrib/download-prerequisites
$ cd
$ mkdir Gcc-build
$ cd Gcc-build
$ ../Gcc/configure --prefix=$HOME --enable-languages=c,c++,fortran
$ make -j8
$ make -j4 install
The --prefix=$HOME option will install binaries, support libraries etc
under your home directory; if you want to put it somewhere else, specify
it as an alternative argument.
The build directory has to be separate from the source directory,
this is a frequent source of weird build errors. Adjust directory
names to taste.
The "-j8" option will use eight parallel compilations if possible;
adjust to approximately the number of CPUs on your system. Having
2GB memory per job is quite sufficient.
Hope this helps
Thomas
