I have been building GNU Radio from CVS on NetBSD, with all the prereqs installed via pkgsrc. I had a few minor problems which I'll list here in case they are useful to others.
I made a wiki node: http://comsec.com/wiki?NetBSD 1) buildit assumes that everything is in /usr, or perhaps that everything is in the compiler's default paths. This isn't true on NetBSD. I added LDFLAGS="-R/usr/pkg/lib -L/usr/pkg/lib" CPPFLAGS="-I/usr/pkg/include" to resolve this, but obviously that's not portable. One could argue that such flags for the prefix should be added automatically, but it also might be that GNU Radio is being put in /usr/gnuradio while boost, swig, etc. are in the standard place. So, adding --use-prefix=FOO that adds flags for it (with -R on systems that use -R) could be useful, or perhaps even doing this by default per OS - buildit is meant to be maximally helpful, not a paragon of virtue. 2) GNU make is required in some cases. We could fix the makefiles to work with BSD make also, or far easier just make buildit switch on platform to invoke GNU make (gmake on BSD, and surely present on systems that have a hope of compiling the prereqs). 3) Some files are checked in that are written during the build. I use CVSREAD=t so that files in CVS are readonly, and then use ^X^Q to edit them, which does cvs edit, saves a local copy of the repo version, and often allows others to see who is editing what files. So, I wonder if these files should not be checked in. If that's too difficult it would be nice for the build should chmod +w them. gnuradio-core/src/lib/filter/Makefile.gen After looking at this one, I see that it's difficult. The Makefile is missing a dependency for Makefile.gen on generate_all.py, so removing Makefile.gen has no way to rebuild it, plus make chokes on the missing unconditional include. Also, Makefile.gen is unconditionally included. Perhaps creating Makefile.gen from src/lib before descending might avoid this. It would be nice if the generated file had the date and hostname of generation as well as RCD Ids of the generator code. gnuradio-core/src/lib/general/Makefile.gen Same issue I think. src/lib/swig/gnuradio_swig_bug_workaround.h If this is deleted, make regenerates it with no issues. So perhaps this can simply be deleted from CVS. With that, and calling buildit with --prefix=/usr/gnuradio, I was able to build usrp gnuradio-core gr-usrp gr-audio-oss gr-wxgui and am able to run the USB benchmark (4 MB/s via an NEC cardbus ehci, as good as has been reported on NetBSD), the oscope and fft. I could run usrp_nbfm_rcv after making a symlink from /dev/dsp to /dev/sound, and commenting out the following line self.fmrx.squelch.set_threshold(threshold_in_db) The audio doesn't sound right, I think due to USB lossage, but I do hear quieting. I have the EHCI spec on my reading pile... -- Greg Troxel <[EMAIL PROTECTED]> _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
