building gcc trunk on ubuntu11.10

building gcc trunk on ubuntu11.10

[Dirk Moermans]

Hi,

I am trying to build the gcc svn-trunk, in order to play with the
latest C++0x-features.

Since upgrading from Ubuntu 11.04, I have trouble building gcc.

The configure command below used to work:
configure --prefix=/home/dirk/local --enable-languages=c,c++,lto

With the new release I get an error-message:
/usr/bin/ld: cannot find crti.o: No such file or directory

This is caused by the new multiarch system-layout within Ubuntu/Debian.

Can anyone send me the correct ./configure or environment variables to
build the gcc-trunk on a stock Ubuntu 11.10?

Regards
Dirk Moermans

export LIBRARY_PATH=/usr/lib/your_machines_triplet

or you can reuse the patches from the gcc-snapshot package (or even just 
use that package so you don't need to compile).

I highly recommend the latter -- it's a painless way to enjoy a very
recent gcc (it's updated once or twice a month).

I was unsuccessful with the configure command. I am now using the gcc-snapshot.
