Missing library in recent VCS checkouts

[diemmarkus]

hi,
thanks for the hint. could you check if webp is really turned off in your cmake? - we don't need webp anymore and stefan turned it off in 1a5a0c5.

[sfiel]

yes, webp is turned off ... the REMOVE_ITEM error was also removed last week when updating the cmake to our new structure. Please check out the newest version, I have updated the build system on linux last friday

The failure of cmake due to REMOVE_ITEM ceased in aeadc94. Btw. it could already be seen in 1949405 and 20e6f3a as well, didn't test the commits before. The failure to build due to WebP ceased in 1a5a0c5.
Both problems were mentioned only as I thought they may eventually have masked when the actual problem of this issue started.

This issue's actual problem is the failure to launch after compiling successfully as depicted in the first comment's first paragraph.
It started in 1a5a0c5. As of 4799891 (and still e. g. in 93bcf2a) the failure persists, the error message got replaced by nomacs: error while loading shared libraries: libnomacsCore.so: cannot open shared object file: No such file or directory.

I have just installed a archlinux on a virtual machine and i have no problem at all compiling and running the actual master branch on it ... have you already tried to delete the cmake cache?

[pmattern]

Apparently make target install didn't get adjusted to some code changes:

Running nomacs in-tree works here, too. Also, all needed libraries are in place

$ find . -iname '*libnomacs*' 
./libnomacsGui.so
./libnomacsLoader.so
./libnomacsCore.so

But after installing (make install) binary nomacs doesn't find the libraries any longer

$ ldd /usr/local/bin/nomacs | grep libnomacs 
        libnomacsGui.so => not found
        libnomacsLoader.so => not found
        libnomacsCore.so => not found

which indeed cannot be found where they are expected

# updatedb && locate libnomacs 
/usr/local/lib/libnomacsGui.so

(in-tree results omitted).

Thanks ... I forgot to change the install targets.

it is fixed now, altough you have to run ldconfig manually ... Haven't found a possibility to make cmake do this

[pmattern]

Problem is fixed as of 9e98278.

The need to run ldconfig depends, among other, on the selection of directories which are searched for shared libraries by default, AFAIK.
E. g. on Arch Linux it does not have to be run if switch -DCMAKE_INSTALL_PREFIX=/usr had been added to the cmake invocation of nomacs as /usr/lib is considered anyway. If on the other hand cmake was run without any optional switch running ldconfig won't do as /usr/local/lib still isn't considered. Rather, the latter needs to be added to the ld.so configuration files before running ldconfig.
But I do not think this has any real relevance as nomacs will be installed by distribution packages most of the time and packagers should make sure that shared libraries are taken into account during installation of binary packages if needed.

Issue can be closed, IMO.

thanks a lot
