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 .
It helps to know how you configured GCC.
[Gaurav ] - This is how I configured my gcc
$ /local/gagupta/gccfolder/crosscompile/gcc-4.4.6-20120305/configure --prefix=/local/gagupta/gccfolder/cross-tools --target=x86_64-unknown-linux-gnu --without-headers --with-newlib --disable-decimal-float --enable-languages=c --disable-threads --disable-libgomp --disable-libmudflap --disable-libssp --disable-shared
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 .
Your configure does not specify --sysroot=.
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.
What does the config.log file in x86_64-unknown-linux-gnu/libgcc say?
There will be a command which failed and a listing of the program it
was executing. Sometimes it is clear why the command failed. Other
times it may be useful to run the program by hand to see all error messages.
Did you look at libgcc/config.log?
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

make[1]: *** [install-fixincludes] Error 1
make[1]: Leaving directory `/local/gagupta/gccfolder/crosscompileorig/gcc-build'
make: *** [install] Error 2
Is there an error before this? Something which prevents fixincludes from
being created?.
[Gaurav ] Error in current scenario:-

Is there an error before this, that prevents fixincludes from being created?
You have an error: "Bootstrap comparison failure!". Resolve that before
working on other problems.

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.)
Not every directory is used for every build. In this case, the libada
and gnattools directories are not needed unless you are building an
Ada compiler.
[Gaurav] - what configuration options are supported by all the libraries .it is enable static and enable shared .
Building static or dynamic libraries has nothing to do with
whether a gcc sub-directory is needed for your build.
In this build, you apparently have --languages=c,c++,fortran,java,objc.
Try working on one issue at a time. Post exactly what you are doing and
what the results are. Don't give "snapshots".
