My experiences building Mozilla M15 under NetBSD/i386/a.out has been less
then fruitful. Sorry for the lack of patches and the length of this post.
First problem I had:
'gtk-config --libs' returns a string that will not be directly usable by
'ld'. After you run 'configure' in the top level mozilla tree, edit
config/autoconf.mk and change the TK_LIBS line to:
TK_LIBS = -L/usr/X11R6/lib -R/usr/X11R6/lib -lgtk -lgdk -L/usr/pkg/lib -R/usr/pkg/lib -lgmodule -lglib -lintl -lXext -lX11 -lm
Second problem I had:
Various Mozilla shared libraries get linked with a static libintl.a. This
will result in 'RSS relocation ...' sorts of messages from the linker as
it is creating these libraries. Every time this has ever happened to me
before, the resulting shared libraries wouldn't work. To fix this, build
and install pkgsrc/devel/gettext. Then run the following script in
pkgsrc/devel/gettext/work/gettext-0.10.35/intl:
#!/bin/sh -x

Install the resulting libintl.so.0.1035 into /usr/pkg/lib and run
'ldconfig' if needed.
Third problem I had:
The resulting browser will drop core. Here is the stack trace from gdb
with a standard 'configure':

I have no idea why there are '??' in various places. If you build the
browser with 'configure --enable-optimize --disable-debug' you get the
following:

The function 'JS_NewStringCopyZ' does appear to contain a strlen and if
you go back to the original build and run the browser in gdb you can set a
break point and catch it in the act, as it were. The strlen function is
passed a pointer 0x80004005 which is invalid.
I have not had time to unwind things further to see where this value comes
from. I don't know if an ELF build would work better, nor have I tried a
different compiler.
