 I am trying to collect all ideas/hacks I used to build software using pkgsrc on Solaris 10 SPARC.
 The process is in progress. I am happy to get comments, ideas and exchange the experience: **mercurius(@)elming.org**

 I use gcc 5.5 from OpenCSW. I installed Sun Studio 12.3 but I wasn't successful in building anything in the pkgsrc tree, and most of the packages need gcc.
 Also, I built gcc 9.5 from source, see [GCC 9](#gcc-9).
 
+**Those packages are 64-bit. pkgsrc suggests to use ABI=64 in its manual (see below). I think I will try to build 32-bit ones too, or you can try if you want.**

 ## Why Solaris 10?
 
 I have Sun Ultra 60 and Sun Blade 100, Solaris 11 cannot be installed on them.

 I disabled `groff-docs` just running: `bmake install PKG_OPTIONS.groff=-groff-docs CFLAGS+=-D__EXTENSIONS__`  
 I guess I will try to build `py-pdf` without Pillow if another package would need it...

+pkgsrc has fltk 1.3.9 which I couldn't build using gcc. If I tried Sun Studio, there was an error about ELFCLASS.  
+I found a solution. I downloaded fltk 1.3.5 and built it using gcc just by `./configure & gmake` with pkgsrc options, then put to the `work` subdirectory and made a package. Then, the packkage `fltk-1.3.9` actually has version `1.3.5`, but it seems to work...

+A couple of files have missing header files - I think, it's because Solaris has functions declared in other files than NetBSD.
+
+But the trickiest part was the font path. TigerVNC builds its own X.org, and its `./configure` has a parameter to set font paths. But in my case it didn't work.
+By default, it sets  
+`COMPILEDDEFAULTFONTPATH = ${prefix}/share/fonts/X11/misc/,${prefix}/share/fonts/X11/TTF/,${prefix}/share/fonts/X11/OTF/,${prefix}/share/fonts/X11/Type1/,${prefix}/share/fonts/X11/100dpi/,${prefix}/share/fonts/X11/75dpi/`
+
+I guess it would work, but somehow `${prefix}` wasn't resolved to a variable (it may be because `/bin/sh` is used somewhere which is horribly broken on Solaris).  
+I had to replace this line in all Makefiles and `.h` files where I found it, and put
+`COMPILEDDEFAULTFONTPATH = /usr/openwin/lib/X11/fonts/misc/,/usr/openwin/lib/X11/fonts/TrueType,/usr/openwin/lib/X11/fonts/Type1/,/usr/openwin/lib/X11/fonts/100dpi/,/usr/openwin/lib/X11/fonts/75dpi/` - to use Solaris fonts.
+
+Also, I needed to install `x11/xsetroot` and `wm/twm` (oh, I haven't tried to run CDE yet in VNC!).
+
+TigerVNC has one more trick. Because SPARC is big-endian, when I try to connect from x86-64 (a little-endian machine), it just shows me a white screen. And on the SPARC side, one of Xvnc threads gets crashed. `vncviewer` on Linux must be run with `-encoding hextile`.

 Also, I used ChatGPT asking questions and copy-pasting errors. Sometimes it provided too much information, but it could help where to look/patch/fix/etc.
