--- Begin Message ---Dear All, We are trying to build a cross gcc which will be hosted on cygwin and produce binaries for Linux/x86. our setup is as below : 1. We are building crossgcc tool chain for the following : host - cygwin build - cygwin target- Linux(x86) meaning, a crossgcc built on CYGWIN, hosted on CYGWIN, but to produce code that will run on Linux/x86 platform. 2. our environment is as below : Windows 98/ CYGWIN release 1.3.21 / i686 3. built and installed binutils .ok(with warnings)............. tar jxf source/binutils-2.12.tar.bz2 pushd binutils-2.12 mkdir build-${CHIP}-linux pushd build-${CHIP}-linux LDFLAGS='--static' CFLAGS='--static' ./configure \ --target=i686-pc-linux-gnu \ --host=i686-pc-cygwin \ --build=i686-pc-cygwin \ --prefix=${PRO_INSTALL_PREFIX} ${FP} make make install 4. we are trying to build and install glibc2.1.3 and we are getting error as below ========================================= > = > = Building glibc for gcc > = > ========================================= > /sys/build_tools /cygdrive/c/Documents and > Settings/Administrator/Desktop/base/rtlpro_altosys_baseline/private > /sys/build_tools/glibc-2.2.5 /sys/build_tools /cygdrive/c/Documents > and > Settings/Administrator/Desktop/base/rtlpro_altosys_baseline/private > /sys/build_tools/glibc-2.2.5/build-i386-linux /sys/build_tools/glibc- > 2.2.5 /sys/build_tools /cygdrive/c/Documents and > Settings/Administrator/Desktop/base/rtlpro_altosys_baseline/private > creating cache ./config.cache > checking host system type... i686-pc-cygwin > *** The GNU C library is currently not available for this platform. > *** So far nobody cared to port it and if there is no volunteer it > *** might never happen.

Please let us know, if you have come across this problem or we are doing something wrong. Regards, Babu K
