[cfe-dev] Clang on Ubuntu 11.04 (natty) 32 bits

[Fletcher, John P]

Some time ago I attempted to build conceptsGcc on Ubuntu 10.4 (64 bit).  I had done this before on various Fedora systems and this time it would not compile.  I found out with a bit of digging that the problem is that Debian and Ubuntu use a different arrangement of library locations compared to Fedora, when handling both 64 bit and 32 bit libraries.

Fedora: 32 bit: lib 64 bit lib64
Ubuntu 32 bit: lib32 64 bit lib with lib64 provided as a link.

I made some changes in the conceptGcc to get it to compile.

See here for more details: http://c2.com/cgi/wiki?UbuntuLinux

I hope this helps.

John

P.S.  I found the following comment about this:
The fact that Debian maintainers go out of their way to modify and Debianize many software packages sometimes does mean that occasionally patches are required to get upstream sources to work. This is a feature not a bug...

to avoid related problems on gentoo (i have an amd64 cross compiler installed on a i386
userland) i configure with these:

--with-cxx-include-root=/usr/lib/gcc/i686-pc-linux-gnu/4.5.2/include/g++-v4
--with-cxx-include-arch=i686-pc-linux-gnu
--with-binutils-include=/usr/lib/binutils/i686-pc-linux-gnu/2.21/include

and on an amd64 userland i use these:

--with-cxx-include-root=/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.2/include/g++-v4
--with-cxx-include-arch=x86_64-pc-linux-gnu
--with-cxx-include-32bit-dir=32


I do a similar setup for openSUSE FWIW.
