Now I encounter another puzzling problem:
>head config.status 
../../egcs-971127/configure --host=hppa1.1-hp-hpux9.05 --target=m68k-unknown-coff --prefix=/usr/local/m68k -v --with-newlib --norecursion 

My target is embedded 68k with no OS, and since I use newlib-1.8 I
added --with-newlib.

It builds a long way, then:

I'm not sure what's going on.  Is this vsprintf for the host or the
target?  The host (hpux) has vsprintf, and this was detected by
configure.  The target should have it in newlib.

Do you have newlib installed?  Where are your target include files?

Have you read the crossgcc FAQ?

Yes, I have newlib installed, and *other parts of the build process
noticed them correctly*.

For example:


gcc -I../../../egcs-971201/gcc/config ../../../egcs-971201/gcc/scan-decls.c
gcc -DCROSS_COMPILE -DIN_GCC    -g -O2  -DHAVE_CONFIG_H -DHAIFA    -I. -I../../../egcs-971201/gcc -I../../../egcs-971201/gcc/config \
  -DGCC_INCLUDE_DIR=\"/usr/local/m68k/lib/gcc-lib/m68k-unknown-coff/egcs-2.90.20/include\" \
  -DGPLUSPLUS_INCLUDE_DIR=\"/usr/local/m68k/include/g++\" \
  -DOLD_GPLUSPLUS_INCLUDE_DIR=\"/usr/local/m68k/lib/g++-include\" \
  -DLOCAL_INCLUDE_DIR=\"/usr/local/include\" \
  -DCROSS_INCLUDE_DIR=\"/usr/local/m68k/lib/gcc-lib/m68k-unknown-coff/egcs-2.90.20/sys-include\" \
  -DTOOL_INCLUDE_DIR=\"/usr/local/m68k/m68k-unknown-coff/include\" \


The newlib stuff is in /usr/local/m68k/m68k-unknown-coff/include.

>Have you read the crossgcc FAQ?

I think so.


I retried with 971201, same results.  I suppose I could try again
explicitly telling configure where to find the target includes, but as 
you see from TOOL_INCLUDE_DIR it seems to have found them without
help.

Well, as Mike Neuhauser noted in a previous message, there's an
inconsistency in where configure & Makefile expect to put/find the
target include files that we need to resolve.

See my recent post that hasn't been sent out to list yet.  I finally
got this working.

The problem was that libgloss.h was included in gcc build, in which we 
have:




/* Don't set the target flags, this is done by the linker script */
#undef LIB_SPEC
#define LIB_SPEC ""


That's why we always failed linking libiberty for the target.  I
simply edited the specs file in the build/gcc directory to say:

*lib:
%{!shared:%{g*:-lg} %{!p:%{!pg:-lc}}%{p:-lc_p}%{pg:-lc_p}}

It's also true that the correct includes were not used, but
fortunately this was harmless in this case.

After making this change to specs the build completed.  I have just
recompiled an example app for the target and loaded it into the
hardware, which is an mpeg2 satellite receiver, and it is working
normally.

You are trying to build the Fortran runtime which is not supported for
the cross-compiler situation.  You can avoid this by making just C and
C++ using:

    make LANGUAGES="c gcov c++" all install

The approved way is to use

    make cross

which does much the same thing. However, when you come to install the
cross-compiler, "make install" or "make cross install" will still try and
build the Fortran runtime, since target "install" depends on "all" (or
equivalent). So I just use the first method.

Jeff, maybe this minor problem (and a better fix, if there is one) could
be mentioned in the new ECGS install document/FAQ?

Yow.

I've made a note of this in the install instructions and the faq.

I've also checked in a change in the _mainline_ sources for install-cross.
