[SOLVED] Mathematica and freetype-2.9 undefined symbol

[Gh0str1d3r]

Hi all,

since today, I can't start mathematica on my gentoo linux machine. It gives the following error:

Code: Select all

/usr/local/Wolfram/Mathematica/11.3/SystemFiles/FrontEnd/Binaries/Linux-x86-64/Mathematica: symbol lookup error: /usr/lib64/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var

What could be the reason for this problem? The file /usr/lib64/libfontconfig.so.1 is part of the media-libs/fontconfig package. Re-installing the package does not help. revdep-rebuild and emerge @preserved-rebuild don't find the broken link. Any suggestions?

You upgraded media-libs/freetype?

[Gh0str1d3r]

I rebuilt that package, too.

You tried to downgrade package to 2.8?

[Gh0str1d3r]

Same error with 2.8.1

Edit: I forgot to rebuild media-libs/fontconfig after the downgrade of media-libs/freetype. Now it works. Is this a bug?

[Gh0str1d3r]

Actually, after downgrading, I can't start kde anymore. The error message is "Could not start kdeinit5" when I try to log in. When I upgrade again to freetype-2.9 then I can also log in again. Is there any way that would allow me to work with kde and with mathematica?

I don't think, just that mathematica (a binary package) need version 2.8.

Yes because I have freetype 2.8 and media-libs/fontconfig 2.12.6 with plasma unstable 5.12.3.
Probably you can run these step (I'm not sure if work and I've no idea if break somethings )

Code: Select all

# emerge -1 =media-libs/freetype-2.8.1
# emerge -1 media-libs/fontconfig
# revdep-rebuild --library 'libfontconfig.so.1'

[Gh0str1d3r]

Works, thank you!

[FR3141]

Code: Select all

# emerge -1 =media-libs/freetype-2.8.1
# emerge -1 media-libs/fontconfig
# revdep-rebuild --library 'libfontconfig.so.1'

I have the same issue but I don't want to downgrade and then rebuild a dozen or so packages.

Is it possible to suppy mathematica with the earlier version of freetype libraries through a variable like LD_LIBRARY_PATH or something similar? Does mathematica have a directory where the older libraries could be installed?

since today, I can't start mathematica on my gentoo linux machine. It gives the following error:

Code: Select all

/usr/local/Wolfram/Mathematica/11.3/SystemFiles/FrontEnd/Binaries/Linux-x86-64/Mathematica: symbol lookup error: /usr/lib64/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var

I discovered the source of the problem. Mathematica includes its own freetype.so.6 library in the directory ${TopDirectory}/SystemFiles/Libraries/Linux-x86-64. This freetype library will call the system fontconfig which will give the error.

To fix this, just remove or rename the mathematica freetype.so.6 library. This will force Mathematica to use the system freetype library.

This solution will allow one to keep the latest freetype-2.9 and no downgrade will be necessary.

If Mathematica gives other errors on startup, like with libz.so, check if that library is installed in ${TopDirectory}/SystemFiles/Libraries/Linux-x86-64 and if so then remove or rename it.

I hope this helps.

Thanks! I had the same problem (well, with Wolfram CDF Player) and I was able to get it working using your solution of removing libfreetype.so.6 and libz.so.1 from /usr/local/Wolfram/CDFPlayer/11.3/SystemFiles/Libraries/Linux-x86-64/.

and the solution:

Code: Select all

sudo rm /usr/local/Wolfram/Mathematica/11.0/SystemFiles/Libraries/Linux-x86-64/libfreetype.so.6
sudo ln -s /usr/lib64/libfreetype.so.6 /usr/local/Wolfram/Mathematica/11.0/SystemFiles/Libraries/Linux-x86-64/libfreetype.so.6
