Re: [Discuss-gnuradio] Check for gr-ctrlport

I can confirm I had the same problem. Adding -DENABLE_GR_CTRLPORT=TRUE helped, 
but it should be enabled without it also, according to the cmake log.

Hi Tom,

Thanks for the reply. This will work for me, but it seems some cmake
magic is missing from the build procedure because GR_CTRLPORT is not
defined in the config.h that I have. Here are the contents:

#ifndef GNURADIO_CONFIG_H
#define GNURADIO_CONFIG_H
#ifndef TRY_SHM_VMCIRCBUF
#define TRY_SHM_VMCIRCBUF
#endif
#ifndef GR_PERFORMANCE_COUNTERS
/* #undef GR_PERFORMANCE_COUNTERS */
#endif
#ifndef GR_CTRLPORT
/* #undef GR_CTRLPORT */
#endif
#ifndef ENABLE_GR_LOG
#define ENABLE_GR_LOG
#endif
#ifndef HAVE_LOG4CPP
#define HAVE_LOG4CPP
#endif

#endif /* GNURADIO_CONFIG_H */


The cmake step says gr-ctrlport is enabled.

Alex
