Detecting Fortran/C compiler

[yamen]

I am trying to install Scalapack through the installer 0.9.
I am facing this error since the morning : Detecting fortran compiler ..... unkown
Detecting C compiler ..... unkown
I said error because i am suspiscious that it is the origin of the errors when trying to use blas library. problem of linking

Yamen,
what compilers do you have? and what errors do you get when linking to BLAS? you should make sure, btw, that the compiler you provide to the installer is the same that you used for compiling the BLAS (if you compiled it).
Let us have more info in order to support your request.
Thanks

Thanks I have resolved this problem in fact my F77 compiler is g77 et my C compiler is gcc. So I disabled the test in the script of framework.py and set it manually to GNU.

But the problem now that I am facing a problem in the communication betwwen fortran and C when testing the libraries generated there is an error continuously "undefined reference to" and the name of functions. I think that there is a problem with underscoring done by fortran. how i can beat this? is it a matter of flags ? plz give me some hints

Obvious...
the framework.py script is there for a good reason and should not be disabled...
The F77 and C compilers should be set to mpif77 and mpicc respectively. If you have them in your PATH the installer can detect them automatically, otherwise you can provide them through the --mpicc=[CMD] and --mpif77=[CMD] flags.

Yes I konow that the framework.py if there for a good reason... which is testing and identifying your compilers and since the test wasnt efficient I dont know why ( result unkown) then I write it manually

Yamen,
the script also does other things.
As for the compiler, the script tries to detect which compiler you are using in order to set a few parameters that are essential for some compilers (e.g., the intel compilers). In the case where it says "unkown" it doesn't mean that it's not going to work.
However, if you want us to help you, please do what I asked you to do (either put mpicc and mpif77 in your PATH or provide them through the --mpicc and --mpif77 flags). Then, if you still have an error, please let us now what the error is (you should copy/paste it here). Otherwise, I can't do more than this.

thank you for your help but the mpicc and mpif77 exist in PATH and so i think the problem is another.
In fact I can use as fortran compiler f77 or ifort.
I tried with f77 but it adds underscore to the functions and so when testing routines of scalapack manu errors of undefined reference.
So I tried with ifort ( intel compiler ) since it doesnt add underscore but finally i got these errors ;

Yamen,
why do you want to provide such a complicated mpif77 command? the ifort compiler will automatically link to all thos libraries that you're passing. Your setup command should be as simple as this:

Code: Select all

./setup.py --mpicc=mpicc --mpif77=mpif77 --mpiincdir=/nfs/softs/TOOLS/Intel/compiler-9.1/em64t/mpich/include --downlapack --downblas --downblacs


If this does not work, please let me now what error message you get (again copy/paste of the setup.py log would be great).
Thanks
