--- Comment #2 from karl at freefriends dot org 2011-03-28 21:51:03 UTC --- For both gcc 4.5.2 and 4.6.0, I configured it from the original source on ftp.gnu.org, using --prefix=/usr/local/gnu --enable-languages=c,c++, no other arguments. "make install" to install. Here is the gcc -v output. I note that cpp is not even being executed. $ gcc -v hello.c Using built-in specs. COLLECT_GCC=gcc Target: i686-pc-linux-gnu Configured with: ../gcc-4.6.0/configure --prefix=/usr/local/gnu --enable-langua\ ges=c,c++ Thread model: posix gcc version 4.6.0 (GCC) COLLECT_GCC_OPTIONS='-v' '-mtune=generic' '-march=pentiumpro' cc1 -quiet -v -iprefix /tmp/../lib/gcc/i686-pc-linux-gnu/4.6.0/ hello.c -quiet\ -dumpbase hello.c -mtune=generic -march=pentiumpro -auxbase hello -version -o \ /dev/shm/cc34H39x.s gcc: error trying to exec 'cc1': execvp: No such file or directory The /tmp/../lib seems like a clear indication it is finding the empty /tmp/gcc directory. I thought it might be something in my environment causing the failure, but even running with env -i, I get the same error. It is puzzling that you do not see it. I can't think of what else would be specific to my installation. $ mkdir /tmp/gcc $ env -i PATH=/tmp:/usr/local/gnu/bin gcc hello.c gcc: error trying to exec 'cc1': execvp: No such file or directory (the gcc -v output from this env -i run is the same as above.) Thanks, karl
