libg++-980119 wouldn't build with egcs-980129 (patch)

Hi!

Some interfaces between configure scripts were changed in last
snapshot, in a way that libg++ was broken.  Here's a patch that
updates libg++'s configure files so that it builds with the latest
egcs snapshot.

Hi,

Manfred Hollstein already posted a patch for libg++ when he posted the
configure fixes. Look in the egcs-bugs archive.
But I wonder when the configure patch (minus the alpha part) mentioned in
README.libg++ will finally be integrated ;-). It's from August last year!

Bye,
Franz.

Can someone send a copy of this patch to the list?

Thank you.

egcs already has the patch to configure.in.

I don't understand why we need the second patch.  I've configured
and used egcs with absolute pathnames for a long time without
running into these kinds of problems.

That is because some systems use the system regex.h/rx.h instead of
the one included in librx. But configure.in doesn't know how to
make a symlink to /usr/include/foo.h since it assumes symlink pathname
is always relative.

libg++ 2.8.1 980201 is released.

Thanks. Manfred Hollstein sent me a similar patch earlier. Alexandre,
I didn't include your patch for libg++/src/configure.in which commented
out the rx.h dectection on linux.

I just made libg++ 2.8.1 980201. It seems to work with both egcs
980129 and libstdc++ 2.8.0.

Thanks.

This is a libg++ addon for libstdc++ 2.8.x and egcs. It is needed only
if your applications depend on libg++ and the dependency on libg++
cannot be removed easily. The standalone libg++ is not longer needed.

The libg++ and librx have been tested with

1. egcs 980129 on linux/x86/libc 5, linux/x86/glibc 2.0.5c,
   linux/x86/glibc 2.1 and linux/alpha/glibc 2.0.6.
2. gcc 2.8.0 971225 and libstdc++ 2.8.0 on linux/x86/libc 5.

It is available at

ftp://ftp.yggdrasil.com/private/hjl/libg++-2.8.1-980201.tar.gz

Patch for libg++ 2.8.1 980119 is also available at

ftp://ftp.yggdrasil.com/private/hjl/libg++-2.8.1-980119-980201.diff.gz

Just put libg++ and librx under the egcs or libstdc++ source directory,
i.e.,

# cd src/egcs
# gzip -dc xxxxxx/libg++-2.8.1-980201-tar.gz | tar xf -

Or

# cd src/libstdc++-2.8.x
# gzip -dc xxxxxx/libg++-2.8.1-980201-tar.gz | tar xf -

Potential problems with libstdc++ 2.8.x:

1. Since gcc 2.8.0 is installed under /usr on Linux/GNU, libstdc++
   should be modified to reflect it. Otherwise incorrect header files
   and libraries may be used. A patch is available upon request.
2. libstdc++ 2.8.0 may not support glibc 2.1. "make check" may fail
   on systems using glibc 2.1. A patch is available at

   ftp://ftp.yggdrasil.com/private/hjl/egcs-971201.io.diff.gz

3. When --disable-multilib is used to configure libstdc++ 2.8.0,
   "make check" may fail in libio due to a bug in dejagnu which
   cannot find the build directory for libio. You can either
   fix dejagnu or don't use dejagnu in libstdc++ 2.8.0. A patch for
   libstdc++ 2.8.0 is also available upon request.

You also need to check configure.in and configure to see if the
patch enclosed here is already applied. If not, please do

# patch -p0 < README.libg++

Then you can configure/build/check/install egcs normally. Now it
will include libg++.

But I still have this problems. I had to install this patch both in 1.0.1
and current CVS to avoid exactly the error mentioned in the archive. Either
this was reintroduced with Manfred's patches (I couldn't build CVS before
because of the jumptable problem) or is not solved under all circumstances.
H.J, what do you think?

My CVS tree was configured like this:
cd egcs-cvs
tar -xvzf libg++-980119.tar.gz
patch <(manfred's libg++ patch for current cvs)
mkdir objdir
cd objdir
../configure --prefix=/usr --enable-shared --with-gnu-as --with-gnu-ld
--disable-multilib
make bootstrap

Bye,
Franz.

configure doesn't know how to make a symlink from a absolute
pathname. My patch fixes it.
