Re: [Users] Editing .cfg file for a machine to use locally installed external libraries (Simfactory, optionlist)
by Dumsani Ndzinisa 23 Jul '14

Hi Frank and everyone, Yes, I eventually got past the error by leaving blanks on the spaces for the values of most of the libraries' details, in particular for the BLAS library. The system is indeed a Linux system (Linux Mint 17). Thanks for the correction on mixing package names and library names. You really have a point there, it makes a lot of sense to me. However, it has been quite a long while since I did this build. So with regard to the exact error message, I may need to re-do the build and try to replicate the error. Like you said, it was something about the linker not being able to find some library(-ies). I will get back and report on the results once I have re-done this, unless you believe it is not too necessary now.

Useful script?
by Steven R. Brandt 19 Jul '14

19 Jul '14

I created this small script to generate the mpi variables for a cactus cfg file, based on the presence of an mpicc in the user's path. I tested it on several machines. Do you think something like it might be useful in simfactory? Cheers, Steve
