GCC

GCC installation:

• download gcc-4.9.4.tar.gz from one of mirrors (for example http://mirrors.concertpass.com/gcc/releases/) and put it in /usr/downloads/

• download gmp-4.3.2.tar.bz2, mpfr-2.4.2.tar.bz2, mpc-0.8.1.tar.gz (similar place, for example http://mirrors.concertpass.com/gcc/infrastructure/) and put it in /usr/downloads/

• mkdir /apps/gcc if does not exist

• cd /apps/gcc and copy there downloaded packages:

#cp /usr/downloads/gcc-4.9.4.tar.gz .
#cp /usr/downloads/gmp-4.3.2.tar.bz2 .
#cp /usr/downloads/mpfr-2.4.2.tar.bz2 .
#cp /usr/downloads/mpc-0.8.1.tar.gz .
cp /usr/downloads/gcc-8.3.0.tar.gz .
cp /usr/downloads/gmp-6.1.0.tar.bz2 .
cp /usr/downloads/mpfr-3.1.4.tar.bz2 .
cp /usr/downloads/mpc-1.0.3.tar.gz .

• untar all (DO NOT COMPILE !)

#tar xvf gcc-4.9.4.tar.gz
#tar xvf gmp-4.3.2.tar.bz2
#tar xvf mpfr-2.4.2.tar.bz2
#tar xvf mpc-0.8.1.tar.gz
tar xvf gcc-8.3.0.tar.gz
tar xvf gmp-6.1.0.tar.bz2
tar xvf mpfr-3.1.4.tar.bz2
tar xvf mpc-1.0.3.tar.gz

• cd gcc-8.3.0 and create symbolic links:

#ln -s ../gmp-4.3.2 gmp
#ln -s ../mpfr-2.4.2 mpfr
#ln -s ../mpc-0.8.1 mpc
ln -s ../gmp-6.1.0 gmp
ln -s ../mpfr-3.1.4 mpfr
ln -s ../mpc-1.0.3 mpc

this way it will be compiled together with gcc

• ./configure --prefix=/apps/gcc/8.3.0 --enable-languages=c,c++,fortran

NOTE: possible options can be checked on https://gcc.gnu.org/install/configure.html

• make

• make install

ARM installation

ssh to any vtp board as root, go to /apps/gcc, copy gcc-8.3.0.tar.xz from /usr/downloads. Untar it and type following:

cd gcc-8.3.0/
export ALL_PROXY=http://jprox:8082
contrib/download_prerequisites
./configure --prefix=/apps/gcc/8.3.0 --enable-languages=c,c++,fortran --with-float=hard
make 
make install

info from Kelvin:

#
# Quick note on how I built gcc 4.9.2
#
0) ensure the environment variable CCC does *not* exist prior to configure
1) make sure /apps/(gmp, mpc, mpfr, isl) exist
2) foreach (gmp, mpc, mpfr, isl) create lib/shared and mv *.so* into it
   -- This is so that gcc links (statically) with the required libraries and,
   thus, does not need to have LD_LIBRARY_PATH set for compiling.
3) setup a separate build environment for gcc (gcc-4.9.2-obj)
3) do the configure (note that this only builds teh 64bit gcc compiler):
   ../gcc-4.9.2/configure --prefix=/apps/gcc/4.9.2 --with-gmp=/apps/gmp --with-mpfr=/apps/mpfr --with-mpc=/apps/mpc --with-isl=/apps/isl/0.12.2 --disable-multilib --enable-languages=c,c++,fortran
4) make
5) make install
6) make clean
7) go back and mv [gmp, mpc, mpfr, isl]/lib/shared/*.so* to appropriate lib area
8) Create /site/cuesw/gcc/4.9.2/use.conf
