Folks I really need some help on building gcc 4.4.6 .I have tried looking nearly all the gnu gcc material configure option.Nothing seems to be working out . If some one can point me to some worth while material /notes for building it on linux without referring anything on the host .Even that will be great . Here is the snapshot of the steps I am doing .I have my sysroot has /local/gagupta/gccfolder .I have extracted kernel and glibc-headers into sysroot .Now I am trying to build gcc in two step by a script .I keep hitting the wall now and then . 1.Some times it failes in stage2 not able to find some header files . where as the headers files are all good in sysroot . checking for suffix of object files... configure: error: in `/local/gagupta/gccfolder/crosscompileorig/gcc-build/x86_64-unknown-linux-gnu/libgcc': configure: error: cannot compute suffix of object files: cannot compile See `config.log' for more details. 2. Some time it failes trying to locate a directory /bin/sh /local/gagupta/gccfolder/crosscompileorig/gcc-4.4.6-20120305/mkinstalldirs /local/gagupta/gccfolder/crosstoolsv1 /local/gagupta/gccfolder/crosstoolsv1 /bin/sh: line 3: cd: ./fixincludes: No such file or directory make[1]: *** [install-fixincludes] Error 1 make[1]: Leaving directory `/local/gagupta/gccfolder/crosscompileorig/gcc-build' make: *** [install] Error 2 3. Some time I see hell lot of directories mentiond in the below list and some time only 2 .based on changing the configure options . The following languages will be built: c,c++,fortran,java,objc *** This configuration is not supported in the following subdirectories: target-libada gnattools (Any other directories should still work fine.)
