It seems, that definition of ipmi_open_inband() is not protected from
C++ symbol versioning, unlike definitions in most other includes. You
can workaround this e.g. by wrapping freeipmi includes in protection
block in your C++ code:
extern "C" {
#include <freeipmi/udm/ipmi-udm.h>
}
The better way is to encourage developers to fix that difference ;)
wbr&w, dmitry.
