See this FAQ: http://gcc.gnu.org/wiki/FAQ#configure As stated in the installation instructions at gcc.gnu.org/install/configure.html you should not run ./configure, you should build GCC in a different directory from the one containing the sources.
humm... Ok, will revisit everything then. I am just following the standard method of building any linux software: unpack tar, cd to the folder created, type ./configure; make; make install.
You're looking in the wrong file. As the FAQ says, the usual reason is that the runtime linker can't find the prerequisite libraries (which is also stated in the --with-gmp docs at http://gcc.gnu.org/install/configure.html - you should read that too.)
Well, But I was following the instructions here: http://gcc.gnu.org/wiki/FAQ item 5, where it says: "You have to check the file 'config.log' in the directory where the error occurred (denoted by Entering/Leaving directory)." And they gave an example. And in my case, such directory was: " make[2]: Leaving directory `/media/sf_nabbasi/data/Fortran_related/gcc_4_6/gcc-4.6.0' " And that is the config.log file I was looking at. So, you see, I was just following the instructions, and did read it :)
You could try using the makefile linked to at http://advogato.org/person/redi/diary/229.html which makes building gcc much easier (especially if you don't read the documentation about ensuring libgmp.so etc. can be found by the runtime linker)
Thanks, will try it. I've uploaded the correct config.log file now here http://12000.org/tmp/march_27_2011/ and called it libgcc_config.log I see now the errors: configure:3028: /media/sf_nabbasi/data/Fortran_related/gcc_4_6/gcc-4.6.0/host-i686-pc-linux-gnu/gcc/xgcc -B/media/sf_nabbasi/data/Fortran_related/gcc_4_6/gcc-4.6.0/host-i686-pc-linux-gnu/gcc/ -B/usr/local/i686-pc-linux-gnu/bin/ -B/usr/local/i686-pc-linux-gnu/lib/ -isystem /usr/local/i686-pc-linux-gnu/include -isystem /usr/local/i686-pc-linux-gnu/sys-include -V >&5 xgcc: error: unrecognized option '-V' xgcc: fatal error: no input files compilation terminated. configure:3039: $? = 1 configure:3028: /media/sf_nabbasi/data/Fortran_related/gcc_4_6/gcc-4.6.0/host-i686-pc-linux-gnu/gcc/xgcc -B/media/sf_nabbasi/data/Fortran_related/gcc_4_6/gcc-4.6.0/host-i686-pc-linux-gnu/gcc/ -B/usr/local/i686-pc-linux-gnu/bin/ -B/usr/local/i686-pc-linux-gnu/lib/ -isystem /usr/local/i686-pc-linux-gnu/include -isystem /usr/local/i686-pc-linux-gnu/sys-include -qversion >&5 xgcc: error: unrecognized option '-qversion' xgcc: fatal error: no input files compilation terminated. ... configure: failed program was: | /* confdefs.h */ | #define PACKAGE_NAME "GNU C Runtime Library" | #define PACKAGE_TARNAME "libgcc" | #define PACKAGE_VERSION "1.0" | #define PACKAGE_STRING "GNU C Runtime Library 1.0" | #define PACKAGE_BUGREPORT "" | #define PACKAGE_URL "http://www.gnu.org/software/libgcc/"; | /* end confdefs.h. */ | | int | main () | { | | ; | return 0; | } Thanks, --Nasser
