Being completely useless at buildsystems (and nxc having a thoroughly nasty 
and slightly broken one), I decided to start transitioning the nxc source 
code to the framework created by kapptemplate, but haven't really got a clue 
what I'm doing. I'm posting this here because it's the buildsystem created by 
kapptemplate which I'm having a bit of trouble with.

My attempts so far can be found at http://gwright.org.uk/files/nxc-0.1.tar.bz2
Basically, the program is split into three components; nxcompsh, nxdriver and 
nxrun. nxcompsh and nxdriver are libraries and nxrun links to both of them.

Unfortunately, for some reason completely beyond me, nxrun refuses to link to 
nxdriver. This is the complaint it spits out:

/bin/sh ../libtool --silent --tag=CXX --mode=link g++  -Wno-long-long -Wundef 
-ansi -D_XOPEN_SOURCE=500 -D_BSD_SOURCE -Wcast-align -Wconversion 
-Wchar-subscripts -Wall -W -Wpointer-arith -O2 -Wformat-security 
-Wmissing-format-attribute -Wno-non-virtual-dtor -fno-exceptions 
-fno-check-new -fno-common -fexceptions   -o nxrun -version-info  -static 
MainUnix.o 
ConsoleCallback.o ../nxcompsh/libXcompsh.la ../nxdriver/libXdriver.la -lexpat 
-L/usr/X11R6/lib -lxkbfile -lXext
libtool: link: warning: `-version-info' is ignored for programs

MainUnix.o(.text+0xb04): In function `main':

collect2: ld returned 1 exit status
make: *** [nxrun] Error 1

Using a really really horrible hack in the Makefile.am for nxrun as follows, 
it compiles cleanly (but obviously this is a horrible hack and really 
shouldn't be used):

LDADD 
= ../nxcompsh/Cookie.lo ../nxcompsh/Exception.lo ../nxcompsh/MD5.lo \
../nxcompsh/Media.lo  \
../nxcompsh/ParametersList.lo ../nxcompsh/Process.lo ../nxcompsh/ProcessUnix.lo \
../nxcompsh/Protocol.lo  \
../nxcompsh/Proxy.lo ../nxcompsh/Samba.lo ../nxcompsh/Session.lo \
../nxcompsh/SessionInterface.lo  \
../nxcompsh/StringUtilities.lo ../nxcompsh/Transport.lo ../nxcompsh/TransportSSH.lo \
../nxcompsh/Utilities.lo  \
../nxcompsh/XInterface.lo ../nxcompsh/XServer.lo ../nxdriver/NXConnection.lo \
../nxdriver/NXDriver.lo  \
../nxdriver/NXSettings.lo ../nxdriver/Options.lo ../nxdriver/SettingsToParameters.lo 
\
../nxcompsh/libXcompsh.la ../nxdriver/libXdriver.la -lexpat -L/usr/X11R6/lib 
-lxkbfile -lXext

If anyone can suggest what is stopping the symbols being visible in the 
library I'd be very grateful.
