[solved] mousepad 0.6.5. error loading shared libraries

after installing version 0.6.5 from tarball I am getting this error:
/usr/local/bin/mousepad: error while loading shared libraries: libmousepad.so.0: cannot open shared object file: No such file or directory.

The libraries are indeed in /usr/local/lib/

I did get these fatal errors during meson compile and install.  not sure if that is the cause or not.
meson compile -C build:
[15/94] Generating xfce-revision.h with a custom command
fatal: not a git repository (or any of the parent directories): .git
[94/94] Linking target mousepad/mousepad

meson install -C build:
ninja: Entering directory `/user/zBuilds/mousepad-mousepad-0.6.5/build'
[1/31] Generating xfce-revision.h with a custom command
fatal: not a git repository (or any of the parent directories): .git

i can launch mousepad if i use LD_LIBRARY_PATH="/usr/local/lib" mousepad
But shouldn't there be a way to link these during compile with meson? thanks

If you are intending to install this location, then you need to configure ldconfig to trust this library location. See: https://thelinuxcode.com/linux-ldconfig-command/ (sorry about the popups). If not, you can specify a different prefix with meson:

meson setup --prefix=/usr builddir

...so that it installs to /usr/lib instead.

I get these too when I install from tarballs using meson, because they are not from the git tree. I believe they are warnings and can be ignored.

i can launch mousepad if i use LD_LIBRARY_PATH="/usr/local/lib" mousepad

See my comment above regarding adding the library to your LD path or specify a prefix for a trusted location.

Re: [solved] mousepad 0.6.5. error loading shared libraries

thanks for the reply.  that ldconfig read was a good one. i never used that before.  worked great.

what i dont get is the meson compile -C build and meson install -C build commands installed mousepad to /usr/local/bin/ by default.  I assumed then the installation would link the shared libraries automatically.

I've installed an earlier version of mousepad from source before and didn't run into this.  oh well.
