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 . > > 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. > > 2.

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 . -- Michael Eager eager@xxxxxxxxxxxx 1960 Park Blvd., Palo Alto, CA 94306 650-325-8077
