Revision history [back]

I had the same problem, but was due to move a package of "Electric" to "Fuerte". A new node that wanted to build, needed some libraries from other nodes. To do this, these nodes had to export some flags in its manifest.xml specified include path or/and lib path. In the main node cmakelist just had to make a standard target_link_libraries.

<export>
<cpp cflags="-I${prefix}/include" lflags="-L${prefix}/lib -Wl,-rpath,${prefix}/lib -lros -lname_your_libraries_that_you_like_export_to_other_nodes"/>
</ export>
