petsc: Build shared libraries

[jolivetinsar@…]

Hello,

I need to compile petsc with the option --with-shared-libraries=1. I modified the port on my machine, creating a new variant:

variant shared description {build with shared libraries} {
    configure.args-delete   --with-shared-libraries=0
    configure.args-delete   --with-pic=fPIC
    configure.args-append   --with-shared-libraries=1
}

I have to delete --with-pic=fPIC, otherwise it does not run. Then, it configures and builds fine, but when macports checks on the created files, it complains, and restarts the whole process (and does it over and over again):

It says:

--->  Updating database of binaries: 100.0%
--->  Scanning binaries for linking errors: 100.0%
--->  Found 3 broken file(s), matching files to ports
--->  Found 1 broken port(s), determining rebuild order

I did run

port install --no-rev-upgrade petsc +variant

so that it installs it and stops without checking what's wrong. Compiling goes fine.

I then did run

port -d -y rev-upgrade 

to see the problem, and I have this:

DEBUG: Marking /opt/local/lib/petsc/lib/libparmetis.dylib as broken

DEBUG: Marking /opt/local/lib/petsc/lib/libpetsc.dylib as broken

To further investigate the problem, I tried:

otools -L /opt/local/lib/petsc/libpetsc.dylib

that says this file does not exists:

/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_math_petsc/petsc/work/destroot/opt/local/lib/petsc/lib/libpetsc.dylib

There is no /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_math_petsc/ directory, indeed.

I am kind of stuck there. I am probably doing things wrong, but I guess also there is a linking problem somewhere.

Thank you for the help
Romain

Please remember to use WikiFormatting, to fill in the Port field, and to Cc the maintainer of that port.

The issue tracker is not for support questions. You ​already asked for support for this on the mailing list, so that's fine; that's the better place for that. The issue tracker is for bug reports and enhancement requests, so we can consider this the enhancement request to add shared libraries to the petsc port. That's reasonable; we do want ports to install both shared libraries and static libraries, if possible.

​Sean Farley provided a link to an updated petsc portfile that we could consider using.
