Link fails on Ubuntu 16.04 (on WSL) due to undefined reference to symbol 'FcUcs4ToUtf8'

[Tatsuro M. <tma...@ya...>]

I pull the recent git repository and tried to build on Ubuntu 16.04 on WSL.

In linking gnuplot executable I see

undefined reference to symbol 'FcUcs4ToUtf8'

Fontconfig version on Ubuntu 16.04 is 2.11.94.
It is rather old but it shoule have FcUcs4ToUtf8.


I googled by keywords FcUcs4ToUtf8 fontconfig version and found the page.

ftp://ftp.x.org/pub/xorg/X11R7.0/doc/html/FcUcs4ToUtf8.3.html

The version is 2.3.2.

So this seems not to be version issue but issue configuration fontconfig on Ubuntu 16.04.

I will straggle the issue.
