Installing Petsc

[antonio albiñana crespo]

Hi!

I'm new in this world, and I'm trying to install Petsc in order to develop
my final studies project. I have received a few error messages and I have
tried to study the configure.log file:

              Popping language C
*********************************************************************************
         UNABLE to CONFIGURE with GIVEN OPTIONS    (see configure.log for
details):

  File "./config/configure.py", line 190, in petsc_configure
    framework.configure(out = sys.stdout)

line 548, in configureLibrary
    config.package.Package.configureLibrary(self)
  File "/home/ubuntu/Escritorio/PETSc/petsc-2.3.3-p8/python/BuildSystem/config/package.py",
line 331, in configureLibrary
    for location, directory, lib, incl in self.generateGuesses():
  File "/home/ubuntu/Escritorio/PETSc/petsc-2.3.3-p8/python/BuildSystem/config/package.py",
line 160, in generateGuesses
    raise RuntimeError('Downloaded '+self.package+' could not be used.
Please check install in '+d+'\n')

I have seen many messages with:

Possible ERROR while running linker: gcc: opción '-PIC' no reconocida
gcc: opción '-PIC' no reconocida

What am I doing wrongly?

I thank you beforehand for your attention.
