About

Instruction: compiling NetSurf under FreeMiNT.

1. Get the latest available versions of make, mintlib, gcc (I'm using 4.3) for freemint.
2. Create an directory, like "netsurf-dev"
3. I prefer to build optimized for 68020 and higer, so I do: export CFLAGS="-m68020-60 -O2" before building anything.
4. Make sure that pkg-config searches within /usr/local, adjust your mint.cnf to contain the following line:
   setenv PKG_CONFIG_PATH u:\usr\lib\pkgconfig,u:\usr\local\lib\pkgconfig
   
5. Get & build curl, first, apply this patch to lib/connect.c (solves connection problems), then configuring it with the following options (to shorten compile time and size):
   ./configure --disable-debug --enable-optimize --disable-ldap --disable-ldaps --disable-rtsp --disable-telnet --disable-tftp --disable-pop3 --disable-imap --disable-smtp --disable-manual -- disable-sspi --target="m68020-60" When cross-compiling, use: sudo ./configure --disable-debug --enable-optimize --disable-ldap --disable-ldaps --disable-rtsp \ --disable-telnet --disable-tftp --disable-pop3 --disable-imap --disable-smtp --disable-manual --disable-sspi \ --target=m68k-atari-mint --host=m68k-atari-mint --prefix=/usr/m68k-atari-mint --with-random=/dev/urandom
6. Get & build freetype2, with this modules.cfg ( again, to shorten compile time and size)
7. Place the getnslibs.sh script into folder netsurf-dev, then run it to checkout the netsurf project libs
8. You either need to patch libnsfb with these patches, or you have to replace the libnsfb directory with these sources which are already patched ( probably the better idea, as the lifetime of the patches is short...)
9. Place makenslibs.sh into "netsurf-dev" - then you compile all the libs with the makenslibs.sh command.
10. Then you checkout netsurf into "netsurf-dev" (svn co netsurf)
11. Currently there is needed some patching:
    • First, there is an problem with the usage of min / max macros with freemint's gcc in:
      
      • layout.c
      • html_redraw.c
      resulting in syntax errors. You need to add the following macros (or similar workaround) in both files:
      

      				#undef min
      				#define min(a,b) ((a)<(b)?(a):(b))
      				#undef max
      				#define max(a,b) ((a)>(b)?(a):(b))
      				

    • 
      If not already in the trunk you also need to add the following to html_redraw.c:
      

                                      #ifdef __MINT__
                                       #ifndef ceilf
                                        #define ceilf(x) (float)ceil((double)x)
                                       #endif
                                      #endif
                                      

    • You need to add the following libs in Makefile.resources to be able to compile convert_image tool: -lz -lm
    • Add stdarg.h to the headers in framebuffer/fbtk.c ( va_list not declared otherwise )
    • As long as FreeMiNT uses an old libxml, you need to patch line 2053 in render/box_construct.c,
      replace:
      

      int ret = xmlNodeDump(buf, n2->doc, n2, 0, 0);
      					if (ret == -1) {
      						xmlBufferFree(buf);
      						return false;
      					}
      				

      with:
      

      				xmlNodeDump(buf, n2->doc, n2, 0, 0);
                      		/* if (ret == -1) {
                              		xmlBufferFree(buf);
                              		return false;
                      		} */
      				

    • Finally you need an libSDL version (unpatched binary version 1.2.14 for atari) that has this gemevents patch or just update your existing libSDL version (link above..) with this patched lib .
12. Place this Makefile.config into the netsurf directory.
13. Compile with make

TODO:

• framebuffer build lacks international keyboard support. try the Config file option: fb_osk to enable on screen keyboard!
• Add SSL certs to package
• Create clean patches for the original Source Package ( SVN trunk )
• Figure out why the monochrom glyphs don't work. Than Fix it.
  • This probably needs fixing in the SDL plotters - but better start debugging in framebuffer.c
• SDL Graphics plotters for 1, 2, 4, 8, 32, 64(?) bit - no, better make an native port...
  • There's currently an problem with Colors for the mentioned plotters, 64 bit isn't supported at all. Probably this is not supported by SDL. What is needed? Graphic primitives that render from one Color format (netsurf format) into the native atari format specified at the command line. This conversion probably needs to take the native color depth into account, because you can also run netsurf with 16 Colors on native 16Bit Colors... THis means you have to code graphics primitives that get XY Bit Input Colors, this must be reduced to 4 Bit Color, than it must be put as an 16Bit pixel to the screen... Applying the following rule would simplifie things: Netsurf just uses the native resolution and can not be forced to use less colors.
• Fix restore of the Pallette when Netsurf gets the focus.( probably it's an palette problem, but maybe it is just an redrawing problem)
• Fix SDL Keyboard event input. Shift is not recognized in the frontend -> result: you can't type https:// or something like that. (Actually, this is not an error. It's not implemented in the framebuffer version. I discussed this on the netsurf list, maybe it helps to use fbtk-rework branch, which shall convert key inputs to unicode... )
• Create RPM for all the ported packages that netsurf requires. ( except the libs shipped with netsurf )
• Make plans on how to make an real GEM Port.
