i've tried to compile program with gpp version 2.24-1 but i've this answer at the and of compiling process : checking for g++... no checking for c++... no checking for gpp... gpp checking for C++ compiler default output... b.out checking whether the C++ compiler works... configure: error: cannot run C++ compiled programs. If you meant to cross compile, use `--host'. See `config.log' for more details. and my config.log is : It was created by configure, which was generated by GNU Autoconf 2.57.

I have the same problem using Xubuntu and 'make'ing Sage-1.7 (math software) from source. I had no problem a couple of days ago with Edgy and Sage 1.61. Need this linear algebra power.... any fixes would be appreciated.......
ssavelan, Make sure build-essential is installed.
hey, thanks man... that's another thing on the list... I like xubuntu because it doesn't have much that I don't want... but I need to add a whole lot of stuff... (just changed from ubuntu_edgy). I was just going to post that I had fixed the problem by installing (rather noobishly) all of available g++ versions.. but, hey, that's why I have cable... sage is now compiling away. build-essential is more of a module tool isn't it? We were using it a few hours ago (on another machine) to upgrade an ATI driver. One of the great things about sage is that it is completely free floating so you can put it anywhere.
ssavelan, build-essential is a "meta-package". It doesn't install anything itself, but it depends on stuff that, uhh, is essential to building.
