It's generated by the configure script. See AM_PATH_ORBIT() macro in
ORBit.m4.

Again, it's generated by the above macro. (which in turn calls
`orbit-config --libs client`)

Yep - that's a bug. It should use the ORBIT_IDL macro. Thanks for
finding this. (fixed in CVS now!)

You shouldn't do this - instead, use the LD_LIBRARY_PATH to identify
the /opt/orbit/lib directory. The point is that you want your code to
use this library; the dynamic linker will link with the first lib it
finds - if you just append /opt/orbit/lib to the end of ld.so.conf it
will find your original lib first.

That sounds likely.
 

You need to do the following:

1) Set your PATH and LD_LIBRARY_PATH:

export PATH=/opt/orbit/bin:$PATH
export LD_LIBRARY_PATH=/opt/orbit/lib:$LD_LIBRARY_PATH

2) Run autogen.sh --prefix=/opt/orbitcpp


This should now all work. (Setting the PATH to /opt/orbit/bin should
enable configure to find the correct orbit-config, which should point
the makefiles at the right include and lib directories.

Hope this helps,

Phil
