RE: need help on 4.4.6

I started all fresh .

This is what I observe If I use the following configure everything works .
AR=ar LDFLAGS="-Wl,-rpath,/local/gagupta/gccfolder/cross-tools/lib" \
       ${SOURCES_GCC}/configure \
        --prefix=${CLFS_CROSS_TOOLS} \
        --target=${CLFS_TARGET} --without-headers


But I give gcc configure as below there are errors .

${SOURCES_GCC}/configure \
        --prefix=${CLFS_CROSS_TOOLS} --target=${CLFS_TARGET} --without-headers --enable-lanugages=c,c++ --enable-__cxa_atexit

make[3]: Leaving directory `/local/gagupta/gccfolder/crosscompileorig/gcc-build/libiberty/testsuite'
make[2]: Leaving directory `/local/gagupta/gccfolder/crosscompileorig/gcc-build/libiberty'
/bin/sh: line 3: cd: x86_64-redhat-linux-gnu/libstdc++-v3: No such file or directory
make[1]: *** [install-target-libstdc++-v3] Error 1
make[1]: Leaving directory `/local/gagupta/gccfolder/crosscompileorig/gcc-build'
make: *** [install] Error 2

This is what I think I need to build gcc with c,c++  lanuages and libc and kernel headers installed in sysroot . but this is not happening not sure what is impacting .
I tried setting Even the environment variable to make sure that gcc looks into the right path but appears nothing is happening .

PATH=$CLFS_CROSS_TOOLS/bin:$CLFS_CROSS_TOOLS/lib:$CLFS_CROSS_TOOLS/lib64:/local/gagupta/gccfolder:$PATH
C_INCLUDE_PATH=$CLFS:$CLFS_CROSS_TOOLS:$C_INCLUDE_PATH
CPLUS_INCLUDE_PATH=$CLFS:$CLFS_CROSS_TOOLS:$CPLUS_INCLUDE_PATH
CPATH=/local/gagupta/gccfolder/usr/include:/local/gagupta/gccfolder/crostoolsv1/include:$CPATH

Your configure does not specify --sysroot=.

Did you look at libgcc/config.log?

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.

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".
