Problem building emacs from bzr

Problem building emacs from bzr

[Nordlöw]

Hi!

I get a build error concerning the files crt1.o, crti.o and crtn.o in /usr/lib when trying to build emacs dev (bzr) on Ubuntu 11.04. The follow lines fixes things but this is ugly:

pushd /usr/lib
sudo ln -s i386-linux-gnu/crt1.o .
sudo ln -s i386-linux-gnu/crti.o .
sudo ln -s i386-linux-gnu/crtn.o .
popd

Is there another way to instruct the build system to find these files in i386-linux-gnu. Is this a bug in structure of the gcc-installation on Ubuntu 11.04? Maybe I should ask gnu.gcc.help aswell...

Any feedback appreciated...

Thanks in advance,
Nordlöw

./configure --help | grep -A1 crt

    --with-crt-dir=DIR      directory containing crtn.o etc. The default is
                            /usr/lib, or /usr/lib64 on some platforms.

Note that the bzr build process has recently changed. You now need to
run ./autogen.sh to generate a new configure script rather than running
autoconf directly. 

I built emacs from bzr sources earlier this week with no problems on two
ubuntu 10.10 boxes.
