The PKGBUILD keeps being broken for me, and fails with

make: Entering directory '/home/krnlpk/.cache/paru/clone/cling/src/build/tools/clang'
make: *** No targets specified and no makefile found.  Stop.
make: Leaving directory '/home/krnlpk/.cache/paru/clone/cling/src/build/tools/clang'

If I edit the PKGBUILD to use Ninja instead of Make, not only the build is noticeably speedier, but it doesn't suffer from this problem (I simply build the right targets instead of doing -C):

I added the suggested patch. Can you give it another try please?

It seems necessary to patch ClingTargets.cmake after installing it.

sed -i 's/IMPORTED_LOCATION_RELEASE\ \".*\/\([^\/]*\)/IMPORTED_LOCATION_RELEASE\ \"\/opt\/cling\/lib\/\1/g' "$pkgdir/opt/cling/lib/cmake/cling/ClingTargets.cmake"

Otherwise, other packages (such as xeus-cling) will try to find libraries in $srcdir other than /opt. If build cache of cling have been removed. xeus-cling will build failed.

The only error is make complaining about that there is no Makefile in build/tools/clang. I tried replacing make everywhere with ninja, adding -G Ninja to the cmake invocation and do

ninja clang ninja cling ... env DESTDIR="$pkgdir" ninja install

and it seems like it built without an hitch.

@krnlpk build on my PC success, maybe you could check whether there is any error or warning in the output?

krnlpk commented on 2021-10-01 08:14

cling 0.9-2 doesn't build for me; in build() the PKGBUILD calls

make -C tools/clang
make -C tools/cling

but no Makefiles are generated inside those directories, so the build fails almost immediately.

archibald869 commented on 2021-09-29 19:07

Thanks for the hint! I updated the PKGBUILD as suggested. Can you please check if it works now?

chn commented on 2021-09-14 16:59

Using the current PKGBUILD, ClingTargets.cmake will not be packaged, which makes other packages failed to build if they have find_package(Cling REQUIRED) in their cmake file (such as xeus-cling).

Simply add install lib/cmake/cling/ClingTargets.cmake "$pkgdir/opt/cling/lib/cmake/cling" to the end of package() will resolve the problem.

I am not familiar with cmake and I could not figure out why cling does not install this file automatically. Maybe it is just a little bug?

I just tried to build and install it in a fresh Arch environment and it succeeded without any problems. How do you build the package?

DarioP commented on 2021-08-11 13:40

With the unmodified PKGBBUILD, I am getting an error about some missing doc file. I do not really care about local documentation. Is anyone getting the same?
