Hello,
I'm a bit confused about the locale dir stuff in VDR 1.6.0 especially wrt. plugins. newplugin hardcodes LOCALEDIR to $(VDRDIR)/locale without taking Make.config into account at all. The result is that plugins will try to place their *.mo into a wrong location if LOCDIR was customized in in VDR's Make.config and/or "make install" was used. I suppose the attached patch would fix that.
However that does not address weirdness in main VDR's locale dir handling; the value set for LOCDIR in Make.config gets built into vdr as the compile time default locale dir, but but "make install-i18n" will install the *.mo somewhere else unless one sets identical value for LOCALEDIR in Makefile (setting it in Make.config does not have any effect). Are both LOCDIR and LOCALEDIR needed? I'd try to clean this up and post a patch that fixes it if I knew what the intention is :)
