[csw-maintainers] Building tightvnc (was: Can't run Sun Studio in vncserver)

[Maciej (Matchek) Blizinski]

I've spent some more time on tightvnc. There was a response from their
mailing list, perhaps I'll get some help there. I'm currently trying
to build it the simplest way possible, just to get it to build, and
then gradually tidy it up. I'm using a short shell script. It
currently fails with:

gmake[3]: Leaving directory

gmake[2]: *** [Xvnc] Error 1

The libos.a library in fact refers to the ffsl symbol:

maciej at netra ~/src/vnc-nongar/vnc_unixsrc/Xvnc/programs/Xserver $ nm
os/libos.a  | grep ffsl
[51]    |         0|       0|FUNC |GLOB |0    |UNDEF  |ffsl
[91]    |         0|       0|FUNC |GLOB |0    |UNDEF  |ffsl
[51]    |         0|       0|FUNC |GLOB |0    |UNDEF  |ffsl

...and libdix.a contains it:

maciej at netra ~/src/vnc-nongar/vnc_unixsrc/Xvnc/programs/Xserver $ nm
dix/libdix.a | grep ffsl
dix/libdix.a[ffsl.o]:
[9]     |        16|      72|FUNC |GLOB |0    |2      |ffsl
[1]     |         0|       0|FILE |LOCL |0    |ABS    |ffsl.c

The script and its output:
http://netra.chopin.edu.pl/~maciej/tightvnc/tightvnc-1.3.10-20090909-095450-build.sh.txt
http://netra.chopin.edu.pl/~maciej/tightvnc/tightvnc-1.3.10-20090909-095450.log

I find it strange that it doesn't find this symbol, because
dix/libdix.a is present in the cc invocation (see above). Do you have
any ideas what might be the problem?
