Issue installing a GNAT cross-compiler
 
Hello,
 
I am trying to build a GNAT cross-compiler for xilinx zynq zedboard (ARM Cortex-A9)
and I'm facing the well known issue "fatal error: sys/socket.h: No such file or directory"
I have read previous threads regarding this error and followed recommendations but the trouble persists
 
What I have done up to now:
 
- Installation of native gcc-4.8.2 and binutils-2.4
- Installation of cross-compiler (same versions) WITHOUT ada support
 
- Installation of rtems-4.11 WITHOUT ada support, to generate the missing <sys/socket.h> [1]
                ../rtems/configure --target=arm-rtems4.11 --enable-rtemsbsp="xilinx-zynq" --enable-networking --enable-posix --enable-cxx --enable-tests --enable-multilib --prefix=$RTEMS_INSTALL_DIR
 
- Trying to build GNAT cross-compiler WITH ada support but ran into issue "fatal error: sys/socket.h: No such file or directory"
                ../gcc-4.8.2/configure --enable-threads=rtems --with-gnu-as --with-gnu-ld --with-newlib --verbose --with-system-zlib --disable-nls --enable-version-specific-runtime-libs --enable-languages="c,c++,ada" --target=arm-rtems4.11 --prefix=$PREREQUISITES_INSTALL_DIR/gcc-cross-c-cpp-ada-4.8.2 --with-gmp=$PREREQUISITES_INSTALL_DIR --with-mpfr=$PREREQUISITES_INSTALL_DIR --with-mpc=$PREREQUISITES_INSTALL_DIR --with-isl=$PREREQUISITES_INSTALL_DIR
 
                
I think I missed a step after generating socket.h
I checked that rtems install directory is in $PATH
but I do not know if there are other tips to do for this header to be found during the GNAT cross compiler build
 
Can someone clarify that for me
                
Thank you for your help
Regards,
Gabriel Brusq

* RTEMS has these .h files but not until you have built and installed RTEMS.
* When building a C/C++ toolset, you also build the newlib C library, so the
* build procedure for an RTEMS GNAT toolset requires that you build a C/C++
* toolset, then build and install RTEMS with --enable-multilib, and finally
* build the Ada part of the toolset.
