This is a known bug in libgazebo for 0.3.0. See... damn, SourceForge is down. Ok, look in libgazebo/gz_iface.c, in the gz_iface_open() function, and change the test following the mmap() call to check for MAP_FAILED rather than non-zero. I.e.: // Map the mmap file self->mmap = mmap(0, size, PROT_READ | PROT_WRITE, MAP_SHARED, self->mmap_fd, 0); if (self->mmap == MAP_FAILED) { GZ_ERROR1("error mapping device file: %s", strerror(errno)); return -1; } Recompile, etc. Should sort it out.
