The julia language loads libraries at run time by using the .so filename. We
work around this in the julia package by symlinking the needed sonames into
%{_libdir}/julia/, e.g.:
for lib in arpack cholmod dSFMT git2 fftw3_threads gmp mprf openlibm
openspecfun pcr2-8 umfpack
do
soname=$(objdump -p %{_libdir}/lib${lib}.so | awk '$1 == "SONAME" { print $2}')
ln -s ../${soname} %{buildroot}%{_libdir}/julia/lib${lib}.so
done
Now we want to automatically generate the needed rpm requires, e.g.:
libarpack.so.2()(64bit)
What I came up with is a rpm-julia-hooks package that julia would BR that
would use rpm fileattrs to generate these. This feels a bit klunky having a
separate package just to do this task.
Does anyone else have any ideas?
Looks like you are trying to use a custom dependency generator in
addition to internal one. If it's for use in a single package then the
following solution should work:
%global _use_internal_dependency_generator 0
%global __find_requires %{SOURCE666} %{_rpmconfigdir}/find-requires
Source666: %{name}-find-requires.sh
Where julia-find-requires.sh should be a script that generates custom
requires (prints them to stdout) and then calls internal RPM dependency
generator (passed as $1).
Please dont. Disabling internal dependency generator is a trick from
last decade which has unwanted side-effects and basically should never
be needed or used these days.
Generally speaking putting the fileattrs into a package of their own is
the right thing to do, but can indeed be a bit klunky if its for a
single package only.
I wouldn't necessarily recommend this, but you *can* wrap just the ELF
dependency generator similarly to the above global find-requires trick, eg
Source111: julia-requires.sh
%global __elf_requires %{SOURCE111}
...and then in julia-requires.sh, call the normal elfdeps generator (for
added bonus, save the original %__elf_requires macro someplace and use
that) and in addition do your own thing for files in %{_libdir}/julia/.
