Ah, I forgot to write some more.
1) use /sys/ports/ape-libs/ libjpeg libpng zlib, the last can replace /sys/src/ape/lib/z
2) the zlib's version is 1.2.7, then one line change of ape-libs/libpng/work/libpng-1.6.17/pnglibcon.h
#define PNG_ZLIB_VERNUM 0x1280
to:
#define PNG_ZLIB_VERNUM 0x1270
compile above.
3) nsport/netsurf/mkfile, uncomment
# content/handlers/image/jpeg.$O \
# content/handlers/image/png.$O \
that's all.

Kenji,
I am glad you worked it out. I was preparing a lengthy reply detailing
what you already found out now. I am waiting for libpng to compile
cleanly in ports before I change the mkfile to include support. JPEG
already works though. As an alternative to changing PNG_ZLIB_VERNUM you
can apply Uramekus patch. Do your nsfb still crash viewing BBC News
(linked from the welcome page)? It has started to work for me.

One might ask why to link against libjpeg and libpng when image viewing
functions are alredy available natively in 9front. This is a valid
question, but as it stands, netsurf as a whole is compiled using APE,
and its viewers are made to use libjpeg and libpng which are also APE
libs. At least we have avoided including ‘libgnu’ (an extension of APE,
also available in ports, using a lot of messy GNU code) and are only
using standard APE and some support libraries that also use standard APE
to compile.

Yes, it's still do.

As a start point, I agree with you.
It's much better to do it natively, however, it's also better to have a working nice
web browser for us.

For bison and flex?
I think we should make targets of javascript and truetype fonts.
If cinap or aiju is not busy, they can work it out easily...

Ok, I got jpeg and png images shown on the current netsurf for
9front.
Chanegs are very small:
at nsport/netsurf/mkfile,
CC=pcc
line to:
CC=pcc -DWITH_BMP -DWITH_GIF -DWITH_BMP -DWITH_JPEG -DWITH_PNG
it just ok, and recompile whole.

I suppose you did it for compiling netsurf.
I did it to cheating the zlib, and compiled libpng for ape.
However, both of jpeg and png images are not shown
on the current netsurf.

It feels like this port should be unnecessary.
We have /sys/src/ape/lib/z, which is a bit outdated.
We should just update this instead, and remove the
zlib port.
Right now, the ape/lib/z takes the code from gs,
but if we're updating from the outside world, it'd
probably be a good idea to invert that relationship.
