How to use already installed software

[Victor Eijkhout]

Dorsal insists on installing all sorts of stuff that I already have on the system. How can I tell it to use that?

Normally I wouldn't object to double installations, except that the petsc install crashes since it can't find a blas library.

What platform are you trying to install it on? Please provide some more details regarding your OS version, etc.

In general though, how you go about telling dorsal to use something you already have installed (say petsc) is to:
1. Open platforms/yourplatform.platform, where yourplatform corresponds to your platform.
2. Remove petsc from the list of packages for that platform.
3. Add a definition to PETSC_DIR somewhere on top that points to the petsc version you want it to use.

Just edit the appropriate file in platforms. Remove the packages you
don't want.

After helping Victor with this, I also found that if you just specify
PETSC_DIR and PETSC_ARCH in the platform file, dolfin does not build
with it. But after having dolfin build I went to the download
directory and called the scons commands myself and it built fine.

I haven't quite figured out why, perhaps its because of the way dorsal
tries to put PETSc in the build directory rather than leaving it as an
in source build.

I have not seen this before.

One thing I could suggest is to echo $PETSC_DIR and $PETSC_ARCH in dolfin.package's package_specific_setup. We can see something weird has happened to this variable before it reaches dolfin.package preventing it from seeing the right petsc.

I guess my "bug" is partly just insufficient documentation. A line or
two about how to deal with the platform files in the README would be
helpful.

I will clean up the documentation before the next major milestone, 0.6.0. Thanks for reporting the problem.
