[apluslist] aplus on slackware 9.1

[Vladimir N. Kutinsky]

This error is generated with a Dynamic Linker that can't find at least one
library. Im not sure but i think the problem lies in the location of aplus
libraries (all aplus files, in fact), which is very unusual
(/usr/local/bin/aplus..). 
When trying to load a library, the linker searches thru a number of known
directories that contain shared libraries. If your directory
(/usr/local/bin/aplus-fsf-4.18/lib) is not in the search path, the linker
won't find the libs even if they are all there.

Try to investigate it with the "ldd" utility that prints shared library
dependencies for an executable (a+ resides in /usr/bin/ on my system):
debian:/usr/bin# ldd a+
        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x40027000)
        libIPC.so.0 => /usr/lib/libIPC.so.0 (0x400ee000)
        libcxs.so.0 => /usr/lib/libcxs.so.0 (0x4010d000)
        libcxb.so.0 => /usr/lib/libcxb.so.0 (0x4010f000)
        libAplusGUI.so.0 => /usr/lib/libAplusGUI.so.0 (0x40113000)
        libcxsys.so.0 => /usr/lib/libcxsys.so.0 (0x40270000)
        libcxc.so.0 => /usr/lib/libcxc.so.0 (0x4027c000)
        libesf.so.0 => /usr/lib/libesf.so.0 (0x40282000)
        liba.so.0 => /usr/lib/liba.so.0 (0x40296000)
        libdap.so.0 => /usr/lib/libdap.so.0 (0x403e7000)
        libMSGUI.so.0 => /usr/lib/libMSGUI.so.0 (0x403f8000)
        libMSIPC.so.0 => /usr/lib/libMSIPC.so.0 (0x4072d000)
        libMSTypes.so.0 => /usr/lib/libMSTypes.so.0 (0x4074f000)
        libpthread.so.0 => /lib/tls/libpthread.so.0 (0x40929000)
        libnsl.so.1 => /lib/tls/libnsl.so.1 (0x40939000)
        libdl.so.2 => /lib/tls/libdl.so.2 (0x4094d000)
        libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0x40950000)
        libm.so.6 => /lib/tls/libm.so.6 (0x40a0a000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x40a2c000)
        libc.so.6 => /lib/tls/libc.so.6 (0x40a35000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

In your case, you will probably see something like this:
	...
	libIPC.so.0 => not found
	...

You can try to fix this problem by adding your directory to the search path.
This can be done by editing "/etc/ld.so.conf" file that contains a list of
directories where shared libraries can be found.

Hope this helps,
Vladimir
