[CMake] FindBlas and header file blas.h

2013-03-01 Thread Nicholas Kinar 

Hello,

On Ubuntu 12.04, I am compiling some third-party program code that 
#includes the BLAS header file blas.h.  Although Cmake does find the 
BLAS and LAPACK libraries, I receive the following gcc compiler error:


fatal error: blas.h: No such file or directory

I've tried to change this include to  other files such as lapacke.h 
but the include file is still not found.  What I am doing wrong here?  
My Cmake file is reproduced below.

Thanks, Tim; yes, I can verify that I have installed the developer 
packages.  Here is my bash output when I try to use sudo to install 
libblas-dev.


nkinar@Betty:~$ sudo apt-get install libblas-dev

libblas-dev is already the newest version.

Moreover, running Cmake (via make compilation) tells me that the files 
are found; however, the blas.h header file is not found.

Re: [CMake] FindBlas and header file blas.h

2013-03-01 Thread Tim Gallagher 
And have you tried printing out the value of BLAS_INCLUDE_DIR? I'm not sure 
that actually exists, I don't see it set in my FindBLAS.cmake module. 

What is the path to blas.h? Have you verified it exists and is in one of the 
standard include locations such as /usr/include, /usr/local/include etc? 

It's possible it is in something like /usr/include/blas/blas.h and so it isn't 
found by default.

Re: [CMake] FindBlas and header file blas.h

2013-03-01 Thread Tim Gallagher 
Also worth noting:

I just checked on an Ubuntu machine and the header file is called cblas.h, not 
blas.h. 

If none of that helps, then I'm out of suggestions. I don't use Ubuntu and most 
of my code is in Fortran :)

The issue appears to be that on Ubuntu, blas.h is named cblas.h.  
This file was installed in the /usr/include directory. Changing blas.h 
to cblas.h fixes the problem, and allows the compile to continue properly.

On Ubuntu, blas.h is named cblas.h and is installed into the 
/usr/include directory.  Changing #include blas.h to #include 
cblas.h apparently fixes the problem.
