Hello there, I'm new here, so excuse me if the solution is trivial: i have installed ATLAS and LAPACK on my ubuntu 7 dual core intel machine. now, when i try to install numpy, it tells me it doesn't find these libraries:

I have installed ATLAS and lapack with no errors. ATLAS is in usr/local/lib/ATLAS/: $ ls /usr/local/lib/ATLAS bin doc interfaces Make.Linux_UNKNOWNSSE2_2 README tune CONFIG include lib makes src config.c INSTALL.txt Makefile Make.top tst.o
so, what seems to be the problem?
You haven't actually installed ATLAS. You've just built it. Don't put
in /usr/local/lib/ATLAS/. Put that somewhere else, like ~/src/ATLAS/. Follow the installation instructions in INSTALL.txt. Note this section:
""" There are two mandatory steps to ATLAS installation (config & build), as well as three optional steps (test, time, install) and these steps are described in detail below. For the impatient, here is the basic outline: ************************************************** mkdir my_build_dir ; cd my_build_dir /path/to/ATLAS/configure [flags] make ! tune and compile library make check ! perform sanity tests make ptcheck ! checks of threaded code for multiprocessor systems make time ! provide performance summary as % of clock rate make install ! Copy library and include files to other

Alternatively, if you are not familiar with compiling softwares (and Atlas can be tricky to compile/install), just install the packages provided by ubuntu: sudo apt-get install atlas3-sse2-dev atlas3-base-dev, and it should be fine.
Maybe, maybe not. On 64bit Intel machines running 64bit linux the fedora package raises an illegal instruction error. Since the fedora package is based on the debian package this might be a problem on Ubuntu also. For recent hardware you are probably better off compiling your own from the latest ATLAS version out there. Chuck
