Description tk+gentoo 2019-01-16 17:11:07 UTC

Since version 1.8.21 pkg-config files are generated by the hdf5 cmake build system:https://www.hdfgroup.org/2018/06/release-of-hdf5-1-8-21-newsletter-161/
I haven't found information regarding autotools, thus I suppose this build system does not generate those files.

Since the gentoo ebuild uses autotools, pkg-config files are neither generated nor installed. However theses are needed for platform independent projects and should thus be considered a bug.

Reproducible: Didn't try

Steps to Reproduce:
1. install sci-libs/hdf5
2. run "pkg-config hdf5 --libs"

Actual Results:  
pkg-config fails with the following error:
Package hdf5 was not found in the pkg-config search path.
Perhaps you should add the directory containing `hdf5.pc'
to the PKG_CONFIG_PATH environment variable
No package 'hdf5' found

Expected Results:  
pkg-conf returns the configuration of the hdf5-package

The attached ebuild ports the existing ebuild to use cmake and thus install *.pc files, fixing this bug.

Furthermore it has been tested with the newest version 1.10.4. However it probably still has some unused code in it.

Digging deeper, it seems that the tested versions 1.10.1, 1.10.2, 1.10.3, all are defect by themselves when it comes to *.pc files. Thus a change to cmake *and* an upgrade to 1.10.4 is necessary for *.pc files generation.

Based on your insight, I've created an ebuild for hdf5-1.10.5 (I call it -r1) with EAPI 7, which:

 0. generates the pkg-config files;
 1. makes it possible to use Fortran with CMake;
 2. fixes the location of libraries that .pc files point to (${prefix}/HDF5_INSTALL_LIB_DIR - which tranlsates to /usr/lib64 on amd64 - instead of ${exec_prefix}/lib , which translates to /usr/lib on amd64 );
 3. cleans up a little lint (not all of it).

These fixes work for me. Anything blocking getting this into the tree?
