[Solved] Missing libmythxxx.so files

I've just compiled myth-29 (not the arch version) on manjaro and it was missing library files. I checked and they were all there (/usr/local/lib) so I assumed that for some reason mythfrontend was looking in the wrong place.
I copied all the files from /usr/local/lib to /usr/lib and myth now works perfectly.
Is there an easy way to point myth in the right direction? I've got it working, as I said, but it seems a bit over the top to copy all those files. Copying, of course, was easier than linking but I wonder why the configure/make/make install installs all the files in /usr/local but then looks elsewhere for the libmyths once running.

Hi,
Don't recall doing anything manually, but see if this gives you a start:
Code: Select all
$ cat /etc/ld.so.conf.d/libc.conf
# libc default configuration
/usr/local/lib
That's from my mythbuntu and Ubuntu hosts.

Thanks bill6502. I'll try that later and let you know.

All my main library files are in /usr/lib/ in manjaro. I've installed myth-29 from source on 3 systems now and all myth lib files are placed in /usr/local/lib but it's only manjaro that doesn't see them there.
bill6502, I think your code covers all lib files but it's only libmythxxx on manjaro that gets it wrong.
I don't know if you've tried manjaro but they have all lib files in /usr/lib/ and then symlink /lib, /lib64, /usr/lib64 to /usr/lib, so I think this anomaly is part of the manjaro system.
It seems my original solution is the correct one unless I symlink all the libmyth files - a rather laborious task.

I don't use manjaro. Wondering if this will help:
Code: Select all
$ ldconfig --print-cache|grep myth
libmythupnp-30.so.30 (libc6,x86-64) => /usr/local/lib/libmythupnp-30.so.30
libmythupnp-30.so (libc6,x86-64) => /usr/local/lib/libmythupnp-30.so
libmythui-30.so.30 (libc6,x86-64) => /usr/local/lib/libmythui-30.so.30
...
You may need to rebuild the cache after adding the .conf file above. Try
sudo ldconfig .

Don't know about manjaro, but assuming you built from source using ./configure it uses prefix of /usr/local unless you tell ./configure otherwise e.g. use ./configure --prefix=/usr
Note if using ccache you need to clear it (ccache -C) and fully clean you git tree.

I didn't change anything in the ./configure and all the libmythxxx files are installed correctly - ie /usr/local/lib. But what's happening, only in manjaro, is that mythfrontend looks in /usr/lib/. I've fixed it my way, it's just curious what causes it.
I've installed from source in opensuse (leap and tumbleweed) with no issues.

I assume you tried the sudo ldconfig, but just didn't mention it.
Could need to remove all the stuff in /usr/lib 1st, I really don't
know how duplicates are handled.
Check this, to see if the directory I mentioned earlier is even used:
Code: Select all
$ cat /etc/ld.so.conf
include /etc/ld.so.conf.d/*.conf
There's this:
http://tldp.org/HOWTO/Program-Library-H ... aries.html
especially 3.3.1 that could be added at runtime. Setting LD_LIBRARY_PATH
would be better than copying everything.
Beyond that, I'm officially stumped.

I'm not in manjaro at the moment so I'll look later and recheck that cat /etc/ld.so.conf... and ldconfig.

This what I get from ldconfig
Code: Select all
sudo ldconfig --print-cache | grep myth
[sudo] password for root:
libmythupnp-29.so.29 (libc6,x86-64) => /usr/lib/libmythupnp-29.so.29
libmythui-29.so.29 (libc6,x86-64) => /usr/lib/libmythui-29.so.29
libmythtv-29.so.29 (libc6,x86-64) => /usr/lib/libmythtv-29.so.29
libmythswscale.so.4 (libc6,x86-64) => /usr/lib/libmythswscale.so.4...etc
Trying 'cat /etc/ld-so.conf ...' gets no such file.
So, as you can see, the original libmyth files are not being seen in manjaro /usr/local/lib/ even though myth put them there.
It's working fine with the copies in /usr/lib so I'll carry on that way.

Sorry to hear that. Guess I'd create the file and directory, then put the path
in a .conf file.) Then run sudo ldconfig to update the cache.
But, I'll go away now.

You were right bill6502. I created the conf with /usr/local/lib/ added, removed all the copy files from /usr/lib/ and ran ldconfig. Mythtv now works as it should. The strange thing is that neither of the opensuse systems needed that ld.so.conf.d file.
Thanks.

Thanks for testing that! Sounds like the other boxen include it as a default, or it's just magic.
