Hello, Thank you for your answer Philip. I moved to mandriva 2009 and I try to install now gcc4.4.4 with the sample_fe frontend I installed the GMP 4.3.2, MPFR 2.4.2 and MPC 0.8.2 all in /usr/local when I call configre with ( --with-gmp=/usr/local --with-mpfr=/usr/local --with-mpc=/usr/local --enable-languages=sample_fe ) I get this error although sample_fe/config-lang.in contains: language="sample_fe" !!! and the last line of the generated error mention sample_fe in the list of supported langauges !!! checking for correct version of gmp.h... yes checking for correct version of mpfr.h... yes checking for version 0.10 of PPL... no checking for correct version of CLooG... no : command not found/Bureau/gcc-4.4.4/gcc/sample_fe/config-lang.in: line 7: : command not found/Bureau/gcc-4.4.4/gcc/sample_fe/config-lang.in: line 9: : command not found/Bureau/gcc-4.4.4/gcc/sample_fe/config-lang.in: line 11: : command not found/Bureau/gcc-4.4.4/gcc/sample_fe/config-lang.in: line 13: : command not found/Bureau/gcc-4.4.4/gcc/sample_fe/config-lang.in: line 7: : command not found/Bureau/gcc-4.4.4/gcc/sample_fe/config-lang.in: line 9: : command not found/Bureau/gcc-4.4.4/gcc/sample_fe/config-lang.in: line 11: : command not found/Bureau/gcc-4.4.4/gcc/sample_fe/config-lang.in: line 13: configure: error: The following requested languages could not be built: sample_fe Supported languages are: c,c++,fortran,java,objc,obj-c++,sample_fe Any Idea ?

I am not an expert in handling linux distribution and install directories :( > Hey You may want to simply move the latest source version and install libmpc (http://www.multiprecision.org/index.php?prog=mpc) aswell since the interfaces changed alot since then i based my old front-end code on a gcc 4.0 and i just ended up starting from scratch when working with trunk. But if you want to keep working with that version you can try: configure --enable-languages=c,c++,.... --with-gmp-include=/usr/local/include --with-gmp-lib=/usr/local/lib ... do the same with --with-mpfr-{include,lib} if you have problems. When you manually make install by default things generally go to /usr/local/include for the headers then lib for the actual library you link against unless you specify a prefix. If you want some reference on front-end code you can look a little at mine though mine focuses on working with trunk http://code.redbrain.co.uk/cgit.cgi/gcc-dev/tree/gcc/python?h=python Where pyspec.c is the compiler driver, then py-lang.c is the compiler proper then other files go along with it. Hope this helps in at least some way :) Its confusing but were working to make it simpler! Gcc rocks ;) --Phil
