After checking the posts:

Install gcc on linux with no root privilege

https://stackoverflow.com/questions/9316118/installing-gcc-as-non-root

My problem still cannot be solved so I post it here.

I am trying to install GCC 4.7 on Linux with gcc version 4.1.2 20080704 (Red Hat 4.1.2-52).

I run configure with prefix to be my home directory.

./configure \
    --with-gmp=/remote/home/gcc_4_7_2012_5_28/gmp505 \
    --with-mpfr=/remote/home/gcc_4_7_2012_5_28/mpfr242 \
    --with-mpc=/remote/home/gcc_4_7_2012_5_28/mpc081 \
    --disable-libjava

Then, make is ok. But, make check is not ok, I got error:

make[1]: Entering directory `/remote/home/gcc_4_7_2012_5_28/trunk'

make[2]: Entering directory `/remote/gcc_4_7_2012_5_28/trunk/host-x86_64-unknown-linux-gnu/fixincludes'

autogen -T ../.././fixincludes/check.tpl ../.././fixincludes/inclhack.def

make[2]: execvp: autogen: Permission denied

make install is not ok. 

make[1]: Entering directory `/remote/home/gcc_4_7_2012_5_28/trunk'
/bin/sh ./mkinstalldirs /usr/local /usr/local

make[2]: Entering directory `/remote/home/gcc_4_7_2012_5_28/trunk/host-x86_64-unknown-linux-gnu/fixincludes'

rm -rf /usr/local/libexec/gcc/x86_64-unknown-linux-gnu/4.8.0/install-tools
/bin/sh ../.././fixincludes/../mkinstalldirs /usr/local/libexec/gcc/x86_64-unknown-linux-gnu/4.8.0/install-tools

mkdir -p -- /usr/local/libexec/gcc/x86_64-unknown-linux-gnu/4.8.0/install-tools

mkdir: cannot create directory `/usr/local/libexec/gcc': Permission denied

I cannot get root privilege.

Any help is appreciated.

Thanks !

When compiling GCC, you should never build it in its source tree!

You forgot a prefix in your configure arguments, perhaps something like

mkdir $HOME/gcc-build
cd $HOME/gcc-build
/your/path/to-source-tree/gcc-4.7.0/configure --prefix $HOME/pref \
         --program-suffix -my4.7 \
# other configure arguments go here 

of course, you’ll find your compiler installed in $HOME/pref/bin/gcc-my4.7 so I recommend adding $HOME/pref/bin to your $PATH and $HOME/pref/lib to your $LD_LIBRARY_PATH

You might try to build the GCC MELT [meta-] plugin once you installed successfully your GCC 4.7
