* PROBLEM:

Portage tried to emerge sci-libs/vtk-9.2.2 and then stopped with this error:

-- Configuring done
-- Generating done
-- Build files have been written to: /mnt/Volume_3/Gentoo/temp/portage/sci-libs/vtk-9.2.2/work/VTK-9.2.2_build

ninja: error: '/usr/lib64/libblosc.so', needed by 'lib64/libvtkIONetCDF-9.2.so.9.2.2', missing and no known rule to make it
 * ERROR: sci-libs/vtk-9.2.2::gentoo failed (compile phase):
 *   ninja -v -j3 -l2 failed

* SOLUTION:

I used `e-file libblosc.so` and it pointed out dev-libs/c-blosc. After emerging this package the build continued past that point.

So, the ebuild needs c-blosc as a dependency.

Comment 2 Petross404(Petros S) 2022-12-15 19:10:38 UTC

I think these are needed too.

GENTOO_VM=  CLASSPATH="" JAVA_HOME="/etc/java-config-2/current-system-vm"
JAVACFLAGS="" COMPILER=""

Comment 3 Jesper Saxtorph 2023-06-04 17:53:41 UTC

I had the same problem on an upgrade where vtk needed a rebuild.
I can see I unmerged dev-libs/c-blosc in May, through an emerge depclean if I am not mistaken. So earlier it have been pulled in by another package and thus the problem have not shown it self before.

Comment 4 falsifiability 2023-06-09 00:13:47 UTC

I can confirm this buy. Had the same error when vtk needed a rebuild caused by app-emulation/libvirt.
