after revamping Octaviz' build system, I encountered (as in: someone
told me) a problem with MacOS.

Octaviz builds a shared library. In order for its .oct files to find
this .so library, I add an rpath under Linux to the build flags.
It seems MacOS' linker doesn't know rpath, but uses '-bundles' instead.

Can someone give me a hint how to use this flag?

In case someone wonders: I don't use mkoctfile, because I want to use
precompiled headers. Somehow, the precise order of argurments seem to
matter there, so I must control the order in wich I pass flags to the
compiler (it's entirely possible that I'm just too stupid, but I
couldn't get it to work with mkoctfile and it works using plain g++).

Thomas, are you asking how to use the "-bundles" flag?

If so, I assume you know it is a linker option. I haven't tried to compile any oct-files yet. However, for Matlab, I created mex-files using a makefile. The link phase is

gfortran -funroll-loops -ftree-vectorize -O5 -Wl,-flat_namespace - undefined suppress -bundle -Wl,-exported_symbols_list,/Applications/ MATLAB_R2007b/extern/lib/maci/ -o my_mex_function.mexmaci my_object_code.o /Applications/MATLAB_R2007b/extern/lib/maci/ version4.o -L/Applications/MATLAB_R2007b/bin/maci -lmx -lmex -lmat -lm

I hope that is some help.
