I want to write a C++ program on Linux/Eclipse that uses the matlab engine routines.  As a starting point I'm trying to compile and run the engdemo.cpp example.  It compiles without errors but I get a linker error - cannot find -llibeng.

As far as I can tell, libeng is installed and I have the paths set correctly in Eclipse.  Any suggestions?

Thanks.

What commands do you use to compile with?

Double-check and triple-check the paths.

Remember that the include directory for headers is
different from the include directory for the linker.
Both have to be set correctly.

If you can, have your compiler / linker report what
it attempts to do (use the 'verbose', often -v, compiler
option). Make sure all your linker paths etc are indeed
set as you want them to. Some times IDEs son't quite
work as they are supposed to, and such options don't
reach the actual makefile.

Since you use C++, that mangles the names in the object
code, make sure your compiler/linker combo is supported.
As I understand it - I might be wrong - libraries that
are compiled with one compiler / linker combo might not
necessarily be linkable to code compiled with other tools.

Try one of the following:

In the Properties->C/C++ Build->Settings, tool settings tag under "Libraries" try either "libeng" or "eng" with the " ".
