libstdc++ 2.9.0

libstdc++ 2.9.0

[Gerald Gutierrez]

Hi all.

This may be a little off topic, but I thought the people in this list
will be most knowledgeable in this area. Please email me replies.

I've been trying to install libstdc++-2.9.0 on top of libstdc++-2.8.0
while I was upgrading to egcs 1.1. As it turns out, this is a problem
under RH5.1 because many packages do not have dependencies on libstdc++
as a package, but on libstdc++.so.2.8 as a file. Trying to upgrade
libstdc++, then, breaks a lot of dependencies :

# rpm -Uvh libstdc++-2.9.0-1.i386.rpm 
failed dependencies:
        libstdc++ = 2.8.0 is needed by libstdc++-devel-2.8.0-8
        libstdc++.so.2.8 is needed by groff-1.11a-6
        libstdc++.so.2.8 is needed by qt-1.40-1rh51
        libstdc++.so.2.8 is needed by qt-devel-1.40-1rh51
        libstdc++.so.2.8 is needed by lyx-0.12.0-3
        libstdc++.so.2.8 is needed by ical-2.2-7
        libstdc++.so.2.8 is needed by fvwm2-2.0.47-1

I don't want to force the installation because then the dependencies are
broken and I don't know what havoc may ensue. 

What am I supposed to do ?

1. % rpm -e libstdc-devel
2. % rpm -Uvh libstdc++-2.9.0-1.i386.* --nodeps
3. % rpm -Uvh groff-1.11a-6.src.rpm (!) ; vi /usr/src/rpm/SPECS/groff*
   (change Version 6 to Version 7); rpm -bb /usr/src/rpm/SPECS/groff*;
   rpm -Uvh /usr/src/rpm/RPMS/i386/groff*

or just: rpm --rebuild groff*.src.rpm; 
rpm -Uvh /usr/src/rpm/i386/groff* --force

4. rpm -e qt-devel
   (rpm -Uvh qt-1.40*.src.rpm ....  or just: rpm --rebuild qt-*.src.rpm;
    rpm -Uvh --force /usr/src/rpm/RPMS/i386/qt-*

5. etc, etc ...

Alternatively, you just install libstdc++-2.9 NEXT to libstdc++-2.8
They perfectly coexist.

The only important thing to do when installing egcs-1.1 as default
compiler is to make sure that the link libstdc++.so points to
libstdc++-2.9 :).

I have RedHat 5.0, and use egcs-1.1b without problems.
My links are as follows:
