Re: [Discuss-gnuradio] Windows Port Error

[Robert Roberts]

Hello all,




I ran test_vmcircbuf.exe  several times and each time I get the same 
results, shown below.

Testing gr_vmcircbuf_createfilemapping_factory...
gr_vmcircbuf_mmap_createfilemapping: non contiguous mmap 003F0000 
003F0000 00010000 00400000
....... gr_vmcircbuf_createfilemapping_factory: Doesn't work
Testing gr_vmcircbuf_sysv_shm_factory...
gr_vmcircbuf_sysv_shm: sysv shared memory is not available
....... gr_vmcircbuf_sysv_shm_factory: Doesn't work
Testing gr_vmcircbuf_mmap_shm_open_factory...
gr_vmcircbuf_mmap_mkstemp: mmap or shm_open is not available
....... gr_vmcircbuf_mmap_shm_open_factory: Doesn't work
Testing gr_vmcircbuf_mmap_tmpfile_factory...
gr_vmcircbuf_mmap_tmpfile: mmap or mkstemp is not available
....... gr_vmcircbuf_mmap_tmpfile_factory: Doesn't work
test_vmcircbuf: NOT OK.  We don't have a workable solution


Any thoughts anyone?

Thanks Martin for letting me know where the precompiled utilities were!


Cheers,
~Chris~
