Hi everyone, I am attempting to setup a development environment on my system, which uses the latest gcc and new libraries for my projects. I don't want my programming environment to interfere with my actual production system, and this approach has the advantage that I can easily try out different combinations of libraries. The environment will be entered by executing a shell script that allows me to just use the new libraries and binaries without much fuss. Since I have installed other libraries into this environment, I need to tell gcc where to find them. I set the LIBRARY_PATH variable, but it seems to be ignored. When I compile a program depending on libraries aside from those bundled with gcc, I get linker errors (with LIBRARY_PATH set as shown below), if I pass -L everything is okay. It looks as if LIBRARY_PATH is getting ignored. Here is the script I am running right now: # Where the new compiler is located DEVELOPMENT_ENV=/opt/development_env_2012_06 # Setup path export PATH=$DEVELOPMENT_ENV/gcc-compiler/bin:$PATH # Runtime access to libraries export LD_LIBRARY_PATH=$DEVELOPMENT_ENV/gcc-compiler/lib64:$DEVELOPMENT_ENV/lib:$LD_LIBRARY_PATH # LIBRARY PATHS export LIBRARY_PATH="$DEVELOPMENT_ENV/gcc-compiler/lib64:$DEVELOPMENT_ENV/lib" # INCLUDES export CPATH=$DEVELOPMENT_ENV/usr/include export CPPFLAGS="-L$DEVELOPMENT_ENV/lib -L$DEVELOPMENT_ENV/gcc-compiler/lib64" export CFLAGS="-L$DEVELOPMENT_ENV/lib -L$DEVELOPMENT_ENV/gcc-compiler/lib64"
