Hi Olivier et al I'm having quite a bit of trouble getting gcc 10 to build for our vxworks 5 (5.5.1) target. The first thing I hit is
#if !defined(_WRS_VXWORKS_MAJOR) #error "VxWorks version macros needed but not defined" #endif Our version.h doesn't define that macro (however, there's a _WRS_VXWORKS_5_X defined in vxWorks.h). Amusingly, a few of the system headers do mention _WRS_VXWORKS_MAJOR, e.g. getOptLib.h:#include "vxWorks.h" /* for _WRS_VXWORKS_MAJOR, if defined. */ and everywhere in the headers that use that macro, they are careful to do "#if defined (_WRS_VXWORKS_MAJOR) && (_WRS_VXWORKS_MAJOR >= 6)". For now, I've just monkey-patched _vxworks-versions.h to get the build past that - I suppose what I should do is to patch our version.h system header instead to provide those two macros. But most of the gthread stuff simply doesn't build against our headers. These five patches, and a bogus definition of WIND_USR environment variable (-mrtp doesn't make sense for us, but vx_crtbegin-rtp.o still gets built and that fails if WIND_USR doesn't exist) get the build a little further - I then fail to build libstdc++, but I'd like some feedback on whether vxworks 5 is even supposed to be (still) supported before digging further.
