Error making a cross-compiler

Error making a cross-compiler

[David Fernandez]

	Hi there,

	I don't know if this is the right place for questions about the gcc
build/install process. Let me know the right place otherwise.

	I'm trying to compile a cross-compiler from gcc-4.0.2 sources.

	It is configured this way:

/usr/src/redhat/BUILD/gcc-4.0.2/configure --prefix=/usr/local/gcc-msdos
--with-local-prefix=/usr/local/gcc-msdos --enable-checking=release
--disable-threads --disable-libunwind-exceptions
--enable-target-optspace --with-system-zlib --enable-__cxa_atexit
--enable-languages=c,c++ --host=i386-redhat-linux
--target=i686-pc-msdosdjgpp

	But at a point during the make process I've got this:

make
...
make[2]: Entering directory `/root/gcc-build/i686-pc-msdosdjgpp/gcc'
for d in libgcc; do \
  if [ -d $d ]; then true;
else /bin/sh /usr/src/redhat/BUILD/gcc-4.0.2/gcc/../mkinstalldirs $d;

make[1]: *** [libgcc.a] Error 2
make[1]: Leaving directory `/root/gcc-build/i686-pc-msdosdjgpp/gcc'
make: *** [all-gcc] Error 2


	As far as I can see, both isystem directories don't exist in my system.

	What I'm doing wrong?. Where should I get the missing header files?.

	
	Thank you in advance.

David.

It would be better to start on the gcc-help mailing list.  Also,
consider looking into using crosstool to assist with building.

This is a header that comes with DJGPP's library.  Like most cross
compilers, you have to install part of the runtime package (usually at
least the headers) before you can build gcc's runtime library.

I have source RPMS of GCC-4.0.2 cross-compiler for DJGPP target 
togethere with ones of needed tools at
	http://ap1.pp.fi/djgpp/gcc/cross-compiler/index.html

Tested on Fedora Core 4, but all perhaps should be OK also for other 
versions
