I am trying to migrate from IRIX6.2 OS to Linux. However, I am having several problems with compiling the source codes. Some of the problems are with c++ stream as well as return a char* to the calling function. Therefore, I am trying to install gcc-4.3.2 with the upgrade gcc-g++ compiler, but I am still using the current and old gcc with make3.80-184.1 to build gcc-4.3.2. I cannot trust this compiler, and I am wondering if this is the problem I might be having building gcc-4.3.2.I have run out of options in building gcc-4.3.2. I cannot configure and build gcc-4.3.2, gmp-4.2.4, and mpfr-2.3.2 together. I have to configure and build gmp and mpfr separately to get the library and include files to be generated. Also, depending on where I build them, I might have to do a make distclean when it is time to build gcc-4.3.2. The attached is the configuration files and make ?j1. I have tried all the suggestions to build gcc-4.3.2 from gcc help as well as following the directions from <http://gcc.gnu.org/install>http://gcc.gnu.org/install Also just before make failed, there were several warning message: duplicate constDo you have any suggestions to help me?

I do not know how to go about solving then Please help. I am using gcc-g++3.3.3 compiler and SLES9 on hp pavilion a305w (i686-pc). I am going a native buildYour log tells that you aren't trying to build "only gcc-4.3.2" but to try some kind of "everything at the same time" : binutils, gmp, GCC,... and your build crashing during the 'gmp' build... Traditionally these things have been splitted into smaller pieces so the GNU binutils, the GCC, the 'gmp' etc. sources are 'stand-alone' with their own 'bfd', 'libiberty' etc. subdirs. But there can be those "combined GNU sources" like those GNUpro ones from Red Hat and in them builds like yours should work. But in them many people have worked in order to get things to work together. Ok, something is wrong in your 'gmp' source install : ----------- clip ------------- make[3]: Leaving directory `/usr/local/gcc-4.3.2/binutils' Configuring stage 1 in ./gmp configure: loading cache ./config.cache checking build system type... i686-pc-linux-gnu checking host system type... none-pc-linux-gnu checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for gawk... gawk checking whether make sets $(MAKE)... yes make[2]: Leaving directory `/usr/local/gcc-4.3.2' make[1]: Leaving directory `/usr/local/gcc-4.3.2' configure: error: source directory already configured; run "make distclean" there first make[2]: *** [configure-stage1-gmp] Error 1 ----------- clip ------------- The GCC's "Prerequisites" say that the 'gmp-*' and 'mpfr-*' sources could be installed as 'gmp' and 'mpfr' subdirs into the GCC sources. Did you really do this? Not for instance installing them being "parallel with the GCC sources" ? Building binutils then happens "parallel", totally separately from the GCC sources so one can have '$src/gcc-4.3.2' and '$src/binutils-2.19' but '$src/gcc-4.3.2/gmp' and '$src/gcc-4.3.2/mpfr' for the 'gmp-*' and 'mpfr-*' sources... The $build directory should be a separate one from the sources... Where are your GCC sources? They MUST NOT be in '/usr/local' ! Using that as your chosen '$build' directory sounds really weird. Something like : /usr/local/src for the unpacked srcs like '/usr/local/src/gcc-4.3.2', '/usr/local/src/gmp-4.2.1', '/usr/local/src/mpfr-2.3.2' etc. would be more "normal". After unpacking the srcs there a suitable $build directory could be the : /usr/local/build and configuring & building there... Just as the "Install" Prerequisites are telling, one could then have in '/usr/local/src/gcc-4.3.2' : gmp -> ../gmp-4.2.1 mpfr -> ../mpfr-2.3.2 and both 'gmp' and 'mpfr' being built during the GCC build.... The '/usr/local' is quite like '/usr' in a Linux system, aimed for local-made apps ('bin'), libraries ('lib'), headers ('include') etc. Anything might happen if one thinks that it is not used for anything in the system... I myself use '/home/src' as the install place for all kind of source distributions... I tried the "build 'gmp' and 'mpfr' during the gcc-4.3.2 build and things seemed to work even in a $build != $host case (cross-compiling also 'gmp' and 'mpfr' for the '$host' platform while producing GCC binaries for that...
