Hi, Only LD_LIBRARY_PATH=/home/user/gcc-4.2.0/lib:$LD_LIBRARY_PATH? What about include files? For example, if I want to compile a tipycal hello world program in C, what stdio.h use the compiler, the new 4.2.0 or the old 4.1.2? If I want to compile a program with gcc-4.1.2 instead of 4.2.0, what about the new LD_LIBRARY_PATH=/home/user/gcc-4.2.0/lib:$LD_LIBRARY_PATH order? Need add LD_LIBRARY_PATH=/home/user/gcc-4.2.0/lib:$LD_LIBRARY_PATH order if I compile, for example, gcc/g77 too? -----Original Message----- From: Jose Luis GarcÃa Pallero <ita-garpaljo@xxxxxxxxx> To: <gcc-help@xxxxxxxxxxx> Date: Fri, 23 Mar 2007 08:28:41 +0100 Subject: Installing gcc in a local directory Hello, First of all I should say that I'm a newbie GNU/Linux user. I need to install gcc/gfortran 4.2.0 in my computer. I would like to install it in a local directory, no the standard /usr/local. I configured the package with the options: ../configure --prefix=/home/user/gcc-4.2.0 --enable-languages=c,fortran --with-mpfr=/home/user/mpfr-2.2.1 --with-gmp=/home/user/gmp-4.2.1 and when it was compiled I put in .bash_profile the lines: PATH="/home/user/gcc- 4.2.0/bin:$PATH" export PATH I don't know if it is the only PATH that I should be defined. Should I define any other LIBPATH or INCLUDEPATH? Thanks ________________________________________- After completion of make and make install, to use the compiler you have made, you would also need LD_LIBRARY_PATH=/home/user/gcc-4.2.0/lib:$LD_LIBRARY_PATH (no spaces in either path) Tim Prince
