编译gcc

#export LD_LIBRARY_PATH=/u02/digoal/cloog/lib:/u02/digoal/gmp/lib:/u02/digoal/isl/lib:/u02/digoal/mpc/lib:/u02/digoal/mpfr/lib:$LD_LIBRARY_PATH  
  
#./configure --prefix=/u02/digoal/gcc4.9.3 --with-mpc=/u02/digoal/mpc --with-mpfr=/u02/digoal/mpfr --with-gmp=/u02/digoal/gmp --with-cloog=/u02/digoal/cloog --with-isl=/u02/digoal/isl --disable-isl-version-check --disable-multilib --disable-libatomic  
  
make -j 32  
make install -j 32  

将环境变量加入/etc/profile

export LD_LIBRARY_PATH=/u02/digoal/gcc4.9.3/lib:/u02/digoal/cloog/lib:/u02/digoal/gmp/lib:/u02/digoal/isl/lib:/u02/digoal/mpc/lib:/u02/digoal/mpfr/lib:$LD_LIBRARY_PATH  
export PATH=/u02/digoal/gcc4.9.3/bin:$PATH  

修改ld.so.conf

# vi /etc/ld.so.conf  
/u02/digoal/gcc4.9.3/lib  
/u02/digoal/cloog/lib  
/u02/digoal/gmp/lib  
/u02/digoal/isl/lib  
/u02/digoal/mpc/lib  
u02/digoal/mpfr/lib  
  
# ldconfig
