* INSTALL
* external/Makefile
+ external/libhpdf/*
+ external/libpng/*
+ Added libharu and libpng to Harbour repository.
Now it's possible to use libhpdf as static lib on all
platforms. This is useful because this lib isn't yet part
of Linux distros.
libpng is only built for win/dos/os2 platforms.
It's possible to override libpng location by using
HB_INC_LIBPNG envvar.
* contrib/hbhpdf/Makefile
+ Look for libharu headers in /external dir.
* external/sqlite3/Makefile
- Disabled for bcc. Latest sqlite3 version breaks with this compiler:
---
