undefined symbol: FT_Done_MM_Var

[deepakjois]

This is on Arch Linux.

~$ flatpak run  org.libreoffice.LibreOffice  
/app/libreoffice/program/soffice.bin: symbol lookup error: /lib/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var

[stbergmann]

With what version of LO and the underlying fd.o runtime (flatpak info org.libreoffice.LibreOffice, flatpak info org.freedesktop.Platform)?

For me

$ flatpak run --env=LD_DEBUG=libs,files,bindings org.libreoffice.LibreOffice/x86_64/stable 2>LOG
# terminate LO once started
$ grep FT_Done_MM_Var LOG
        14:	binding file /lib/libfontconfig.so.1 [0] to /lib/libfreetype.so.6 [0]: normal symbol `FT_Done_MM_Var'

shows that, as expected the runtime's libfontconfig.so.1 resolves that symbol from the runtime's libfreetype.so.6. Do you see anything suspicious in the LOG file when you do that (or else, can you provide it here)?

@alexlarsson, any idea?

[deepakjois]

Maybe it is relevant – I first encountered the exact problem when I installed and ran the standard libreoffice package on Arch Linux. After that, I tried flatpak to eliminate the possibility that some libraries on my Arch system were causing problems, but I encountered the same error as shown above.

Below is the info you requested. The command as specified above did not work for me. I had to explicitly set LD_DEBUG before invoking flatpak run …

$ flatpak run --env=LD_DEBUG=libs,files,bindings org.libreoffice.LibreOffice/x86_64/stable

[stbergmann]

No idea why passing --env=LD_DEBUG=libs,files,bindings apparently failed to produce any stderr output from running LO's soffice.bin in the flatpak environment. The LOG.txt you provide is of no use here, it only captures the flatpak executable itself, run outside of the flatpak environment.

[deepakjois]

Ok…thats too bad.

So I ran flatpak run -vv org.libreoffice.LibreOffice. Pasting output below, if it helps:

[stbergmann]

maybe the output of flatpak run --command=ldd org.libreoffice.LibreOffice /app/libreoffice/program/soffice.bin would give a clue

[deepakjois]

Here you go. I also explored the contents of the filesystem by doing flatpak run --command=sh org.libreoffice.LibreOffice, and I realised that even inside the flatpak environment, the program seems to be using libfontconfig and libharfbuzz from my Arch filesystem. I maybe wrong, but I was not expecting that.

[stbergmann]

Those

	libfontconfig.so.1 => /lib/libfontconfig.so.1 (0x00007ffbc53ab000)

should be the libraries in the org.freedesktop.Platform runtime's lib directory. I really have no idea what's going wrong there; maybe @alexlarsson or somebody else has.

[deepakjois]

Ok, I played around a little bit more, and I found that I can run Libreoffice successfully if I do this:

flatpak run --command=/app/libreoffice/program/soffice.bin org.libreoffice.LibreOffice

Similarly, I can run the LibreOffice on my local installation (outside flatpak) successfully when I do:

/usr/lib/libreoffice/program/soffice.bin 

instead of invoking something like libreoffice --writer which is the normal way (which gives the error above). Maybe the wrapper script that invokes soffice.bin has some issues and they show up on Arch, both natively and inside flatpak?

I am just trying to capture as much detail here as possible, but it looks like this may be more of a LibreOffice packaging problem than a flatpak problem.

[stbergmann]

To narrow that down further, does flatpak run --command=/app/libreoffice/program/oosplash org.libreoffice.LibreOffice succeed or fail? What's the output of flatpak run --command=/app/libreoffice/program/javaldx org.libreoffice.LibreOffice?
As you say you have the problem also with non-flatpak LO, does LD_DEBUG=libs,files,bindings soffice of that version produce output, and does that output indicate whether it picks up a wrong libfreetype.so, or why else libfontconfig.so.1 search for FT_Done_MM_Var fails?

[deepakjois]

Ok here are the results (and possibly the root cause of the problem)

This fails

$ flatpak run --command=/app/libreoffice/program/oosplash org.libreoffice.LibreOffice
/app/libreoffice/program/soffice.bin: symbol lookup error: /lib/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var

and this seems to give a strange result. It is picking up the Java installation from my Arch installation

flatpak run --command=/app/libreoffice/program/javaldx org.libreoffice.LibreOffice                                                                                      
/home/deepak/.sdkman/candidates/java/8.0.163-zulu/jre/bin:/home/deepak/.sdkman/candidates/java/8.0.163-zulu/jre/jre/bin:/home/deepak/.sdkman/candidates/java/8.0.163-zulu/jre/bin/classic:/home/deepak/.sdkman/candidates/java/8.0.163-zulu/jre/jre/bin/classic:/home/deepak/.sdkman/candidates/java/8.0.163-zulu/jre/lib/amd64/client:/home/deepak/.sdkman/candidates/java/8.0.163-zulu/jre/lib/amd64/server:/home/deepak/.sdkman/candidates/java/8.0.163-zulu/jre/lib/amd64/classic:/home/deepak/.sdkman/candidates/java/8.0.163-zulu/jre/lib/amd64/jrockit:/home/deepak/.sdkman/candidates/java/8.0.163-zulu/jre/lib/amd64/native_threads:/home/deepak/.sdkman/candidates/java/8.0.163-zulu/jre/lib/amd64 

As you suggested, a wrong version of freetype is getting picked up form the java sdk installed on my system using a tool called sdkman. This is happening both for my Arch native libreoffice installation, and the one in flatpak.

I don’t know what is the right thing to do here is. My expectation would have been that flatpak runs in a sandbox and shouldnt be affected by the java installation on my Arch system.

Anyway, I will disable my local Java version before starting LibreOffice. That should resolve the problem by picking up the right libfreetype.

[stbergmann]

How is that Java installation found, does your JAVA_HOME environment variable point to it, or did you include its bin directory in your PATH, or...?
(LO uses some heuristics to find Java installations, looking at things like JAVA_HOME and PATH. From oosplash, it first calls javaldx to determine which Java installation, if any, to use, then augments LD_LIBRARY_PATH with that Java installation's paths because some versions of Java need(ed) that when instantiating a JVM in a non-Java process like LO does, then spawns soffice.bin with that augmented LD_LIBRARY_PATH. As your Java installation is underneath your home dir, which the LO flatpak can read, it appears that the LO flatpak's javaldx finds that Java installation for some reason---the details would depend on how you "advertise" that Java installation.)

[deepakjois]

I am using this tool called sdkman to manage Java on my computer. I execute a sdkman-init.sh script in my .bashrc. That automatically sets JAVA_HOME and also modifies the path to point to the bin folder with the java binary.

The other interesting thing is that the java installation that gets installed with sdkman contains a local copy of freetype, which overrides the default freetype on both flatpak and Arch. That is a bit unusual. The regular java package in Arch does not have that.

[stbergmann]

So JAVA_HOME was indeed passed from the outside into the flatpak sandbox (as happens for all env vars except a few blacklisted ones). Together with the fact that JAVA_HOME pointed into the home dir that is accessible from within the LO flatpak sandbox, that caused the described effects.
Should be fixed now with 1fbb186 "Find flatpak'ed Java installation via JAVA_HOME" included in the latest build https://flathub.org/builds/#/builders/2/builds/1546. Now only the Java installation included in the LO flatpak should be found, and should be used automatically.
(In case more people ran into this issue: LO stores information about the Java installation it found, and keeps using that on subsequent starts. If there is an issue with an erroneously selected Java installation other than the one included in the LO flatpak at /app/jre, you can either select the correct one under LO's "Tools - Options... - LibreOffice - Advanced" or delete your local ~/.var/app/org.libreoffice.LibreOffice/config/libreoffice/4/user/config/javasettings_*.xml to make LO search anew on the next start.)
