644	Problems with ESP Ghostscript 7.07.1 and a system libpng	lizardo@…	tushar@…	"From
http://archives.linuxfromscratch.org/mail-archives/blfs-dev/2004-February/005199.html:

The current stable espgs version (7.07.1) has a bug which prevents a
system libpng from being detected, so to build a gs binary with PNG
support, we have necessarily to unpack the lipng package inside the
espgs source dir.

The patch
http://www.linuxfromscratch.org/patches/downloads/espgs/espgs-7.07.1-libpng_check.patch,
backported from CVS, fixes this issue. Unfortunately, this fix exposed
another bug when compiling the shared library (see
http://www.cups.org/str.php?L602 for details). For this specific bug, we
don't need a patch, only a instruction modification.

Finally, the following changes are suggested to resolve this issue:
- Add the espgs-7.07.1-libpng_check.patch to the ESP Ghostscript section
  marked as ""required"".
- Change the the shared library compilation instruction to:

make CFLAGS_SO='-fPIC $(ACDEFS)' so

The upcoming 7.07.2 version is supposed to fix these bugs."	defect	closed	high		BOOK	~CVS	medium	fixed	VERIFIED
