I'm trying to install the magma 1.0 RC5 library on my Ubuntu 10.04 LTS x64 but i have this error while compiling :

CLAPACK compiled without errors, but i don't understand why functions are missing.
I used the makefile given in the archive.

CBLAS is not included in CLAPACK.
You have to get it from here
For other MAGMA related question, you can post your question on the MAGMA forum:
