RE: issues with gcc 4.4.6

["GUPTA, GAURAV G (GAURAV)" <gaurav dot g dot gupta at alcatel-lucent dot com>]

I started with clean approach .But I am surely hitting the wall again .

This time around .

I have a script that does following things 

1. Install_binutils
2. install_gcc_cross_1 ( This is with configure option prefix , target and sysroot ) 
3. install_gcc_cross_2 ( This has many more options ) .

After install_gcc_cross1 .I see the first level gcc built fine in target/bin directory.but can not be used for anything .If I unable install_gcc_cross2.I am hitting the below error .



usr/bin/install -c -m 644 libgcc_eh.a /local/gagupta/gccfolder/cross-tools/lib/gcc/x86_64-redhat-linux-gnu/4.4.7/
/usr/bin/install: cannot stat `libgcc_eh.a': No such file or directory

I don't fully understand what your last option is for 
(http://gcc.gnu.org/install/configure.html), but
my guess is that one wants to build a custom native GCC which doesn't 
use the usual '/usr/include'.
Do you know why you are using this?  If you are creating a cross GCC 
then this may cause troubles.
A cross GCC should automatically search the '$sysroot/usr/include', 
nothing else than the
'--with-sysroot=$sysroot' is required.

What you did?  The stdc++ headers and libraries will be created and 
installed during the GCC
build and install. So there shouldn't be any C++ headers and libraries 
for the target when
starting, only the C ones which usually means (all or some) the 
'glibc-*.rpm's and the
'kernel-headers-*.rpm' being extracted into the sysroot.  In your case 
the should be both
the default 64-bit and the optional 32-bit glibc binaries extracted so 
the sysroot has both
the lib & lib64 and usr/lib & usr/lib64 binaries and the one usr/include.

It looks like the process stopped in the libstdc++-v3 install phase...  
Was the directory
'$BUILD/x86_64-redhat-linux-gnu/libstdc++-v3' (where $BUILD is your GCC 
build dir)
even created and filled during the build?  What about the 
'$BUILD/x86_64-redhat-linux-gnu/32/libstdc++-v3'
for the 32-bit libstdc++-v3?

Maybe you should start with a clean board what comes to the sysroot and 
leave the
' --with-native-system-header-dir=${CLFS}/usr' away from the GCC 
configure,  and
start with bare sources after a 'make distclean' or simply doing a 'rm 
-f -r' in the GCC
build directory...
