Starting with a fresh checkout and using
build:static instead of build:arm/x86:static it finally worked.
Furthermore, I managed to compile some of the packages in boox-opensource , though not all:
- dictionary_tool was missing the libz statement again (patch attached)
- cr3, djvu_reader, fbreader_onyx, feed_reader, music_player, rss_reader failed to compile for X86 (not yet tried for ARM) for diverse reasons (not yet tried to debug).
- feed_reader seems to be missing a file (feed_action.cpp)
I've updated the wiki on how to compile boox-opensource packages.
Cheers.
