Installation Help

[Birchmier, Masaki]

I hope this is the proper place to send this message, for installation questions :-)

I am installing a cross compiler on a hp-ux 10.20 system for power pc,
the Make, ends with the following message...

_muldi3
/home/gnu/gcc/gcc-2.95.2/gcc/libgcc2.c:41: stdlib.h: No such file or directory
/home/gnu/gcc/gcc-2.95.2/gcc/libgcc2.c:42: unistd.h: No such file or directory

make[1]: *** [stmp-multilib] Error 1
make[1]: Leaving directory `/home/gnu/gcc/gcc-2.95.2_powerpc/gcc'
make: *** [all-gcc] Error 2

I was hoping you could help with the debug, thanks.

Read the Cross GCC FAQ.  Get newlib.

Hi,

sorry for bothering you, I got the very same error, that Masaki got.
I've been studing the Cross GCC for hours now. And tried and tried...

I've found out that even the suggested shell script 'one.tree-1.6.sh' is
doing strange things
as to say not correctly 'linking' directories. It does not use the
symlink-tree
script, so there are a lot of broken links after the script has been run.

In previous times there had been detailed descriptions about setting up
a cross compiler in the manual at 'gcc.gnu.org' They have disapeared almost
completely. Instead there is only a redirect to this FAQ.

Please could you give me any pointers of how to proceed?

I also tried to use the symlink-tree script to create one virtual source
directory,
first doing binutils-2.9.1 then gcc-2.95.2 and at last newlib-1.8.2.
configuring for target i386-something-linux and make ing all
stops with: include file _G_config.h not found somewhere in the build of
iogetline.c from
the libio subdir of gcc.

Thank you so much
Roland

Are you building for a *-linux* target?  In this case, you'll need
glibc, not newlib, since glibc is supposed to provide _G_config.h.

Yes this is true. I try to compile it for linux. Does this imply, that
newlib is
useless for a linux target?
What I triy to do is to get a library with a smaller footprint.

Thank you,
Roland

I heard someone was porting newlib to GNU/Linux.  But I don't know
whether it's finished, and it will probably have to provide
_G_config.h as glibc does.  Or you may force libio to build
_G_config.h itself (just run `make _G_config.h' in the libio build
dir).

But I foresee more problems.  Unless newlib provides the same crt
object files that glibc does, you'll have to modify GCC so as to use
those provided by newlib.

Re: Installation Help

[Roland Schwarz]

Sorry for bothering you again,

but I am completely lost now.
What did I:

under home/gcc I created:

home/rs/gcc/binutils-2.9.1
home/rs/gcc/gcc-2.95.2
home/rs/gcc/glibc-2.2

and untarred the respective source packages to them then I created

home/rs/gcc/src
home/rs/gcc/build

then I symlinked to one tree:

cd /home/rs/gcc/src
../gcc-2.95.2/symlink-tree ../glibc-2.2
../gcc-2.95.2/symlink-tree ../binutils-2.9.1
./gcc-2.95.2/symlink-tree ../gcc-2.94.2

after this I changed to build and configured for a native build (I am using
linux RedHat 7.0 on a 686)

cd ../build
../src/configure -v

then I tried to make

make all -v

BUT:

gcc -c -DHAVE_CONFIG_H -g -O2 -I. -I../../src/libiberty/../include
../../src/libibery/choose-temp.c
In file included from ../../src/libiberty/choose-temp:29:
../../src/include/stdio.h:32:28: stdio/stdio.h: File or directory not found
(original message in german)

other files not found follow

-------------------------
Some Background:

What I basically try to do is setting up a cross-compile environment where
the target is linux,
but beeing able to use different libraries. (Hopefully one with a smaller
footprint that has debug symbols
stripped or even an older version of the library, while still beeing able to
compile for the host too)

In the hope you can give me another hint.

Roland

Unfortunately, the unified tree doesn't support glibc builds.  This
makes the bootstrapping of a glibc-based target significantly more
difficult than that of a newlib-based target.  I don't recall the
exact details, but you have to point GCC at glibc headers using
--with-headers, build it up to the point of having libgcc, install it,
then build glibc, then go back and build libio and libstdc++.

This should rebuild the source RPM for your architecture.  You'll end up
with a binary RPM you can then install which resides (AFAIK) in
/usr/src/redhat/RPMS.  I'm a relative newbie when it comes to this area
(normally I just get a tar.gz source archive and be done with it).

installation help

[Osama Saad Khan]

Hello

My problem is that I want to install gcc-2.96 alongwith the already
installed gcc-3.2. While going through the GCC mail archives, I came across
your message on the topic. I admit that I have very little experience in
installing gcc or programs with complex configurations involved. I have
downloaded the source rpm for version 2.96 but am at a loss as to how to
continue. Can you please help me out?

Thank you.

Osama
