--- Comment #2 from crivello <crivello at icmpe dot cnrs.fr> 2011-04-20 09:32:56 UTC --- What you need * the exact version of GCC; gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) <-- ubuntu 10.10 * the system type; Using built-in specs. Target: x86_64-linux-gnu * the options given when GCC was configured/built; Configured with: ../src/configure -v --with-pkgversion='Ubuntu 4.4.3-4ubuntu5' --with-bugurl=file:///usr/share/doc/gcc-4.4/README.Bugs --enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr --enable-shared --enable-multiarch --enable-linker-build-id --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --with-gxx-include-dir=/usr/include/c++/4.4 --program-suffix=-4.4 --enable-nls --enable-clocale=gnu --enable-libstdcxx-debug --enable-plugin --enable-objc-gc --disable-werror --with-arch-32=i486 --with-tune=generic --enable-checking=release --build=x86_64-linux-gnu --host=x86_64-linux-gnu --target=x86_64-linux-gnu Thread model: posix * the complete command line that triggers the bug; gcc file.F * the compiler output (error messages, warnings, etc.); and gcc: error trying to exec 'f951': execvp: No such file or directory * the preprocessed file (*.i*) that triggers the bug, generated by adding -save-temps to the complete compilation command, or, in the case of a bug report for the GNAT front end, a complete set of source files (see below). I don't have it. I hope that it is now clear enough.
