When compiling a number of examples from the $VBROKERDIR/examples directory the following error message is printed during linking:

"/user/bin/ld: skipping incompatible $VBROKERDIR/lib/libvport_r.so when searching for -lvport_r"

Similar error messages occurs for all the ORB libraries.

Is there an incompatibility between 32-bit VB8.5 and 64-bit Linux box?

The ld attempt to link 64 bit library due to g generates 64bit code by default on 64bit Linux.

To force g to generate 32bit code, add "-m32" flag to g in the stdmk. For example:

### Platform specific compiler definitions (multi-threaded)
CC         = g   -D_REENTRANT -DTHREAD -DPTHREADS -m32

The stdmk is located in $VBROKER/examples/vbroker.

Note that you should clean up the 64 bits object files (using "make -f Makefile_cpp clean" command) before compiling the 32 bits version.
