I am Using Ubuntu Karmic (9.10) which comes with GCC 4.4
I am trying to compile cuda sdk 2.3 and I am having these messages when I try to run make on the SDK, After I add
NVCCFLAGS += --compiler-options -fno-inline
To common/common.mk

Does anyone know how to use GCC 4.3 instead of GCC 4.4 in Ubuntu? I think that you should replace some symbolic links but I don’t know where.
Thanks

You could uninstall gcc 4.4 and install 4.3. It doesn’t take that long to do with synaptic.

You can open Synaptic from System → Administration → Synaptic Package Manager
Search for gcc and you’ll see an entry for gcc-4.3. Right click on it and select “Mark for instalation”. Click on the Apply button and it will be installed.
Next you should go to /usr/bin and remake the softlink to gcc with version 4.3:
sudo rm gcc
sudo ln -s gcc-4.3 gcc
Let me know if that works ;)

Hello everybody!
I managed to work with Ubuntu 9.10 (AMD64). As you did, I installed g+±4.3 and gcc-4.3 packages and created new symlinks (I think, that is not necessary. Editing CC and CXX variables in /SDKPATH/C/common/commom.mk should be sufficient).
Owing to the fact, that I used a fresh installation, some of you may have some additional problems.
You have to install Glut (I installed the developement-packages, too), libXi-dev and libXmu-dev to get a successful sdk-compilation.
Furthermore, I got errors like …
… after compiling.
To avoid this, add the line
to /etc/ld.so.conf and run sudo ldconfig
Hi all,
I tried changing the common.mk but no luck. Then I decided to properly use the update-alternatives and it worked!
The sequence of commands is:
[codebox]sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.4 44 --slave /usr/bin/g++ g++ /usr/bin/g+±4.4 --slave /usr/bin/gcov gcov /usr/bin/gcov-4.4
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.3 43 --slave /usr/bin/g++ g++ /usr/bin/g+±4.3 --slave /usr/bin/gcov gcov /usr/bin/gcov-4.3[/codebox]
Note that gcc 4.4 still has higher priority when in “auto” mode. You can then check the config by typing:
[codebox]sudo update-alternatives --display gcc[/codebox]
and swap between versions with
[codebox]sudo update-alternatives --config gcc[/codebox]

Here’s a blog post that explains how to do it in some detail:

You don’t have to run update-alternatives or in other ways “hide” your gcc 4.4 from the CUDA system.
