vmware hosted system

Not sure if this might be helpful but I “fixed” the same problem today so that I could build a vm on debian. The “fix” is (although I don’t completely understand the problem…) to remove the #define for NoDbgRegParms, such that it will be defined as empty (in the second #define).
Example:
#if !PRODUCTION && defined(__GNUC__) && !(defined(__MINGW32__) || defined(__MINGW64__)) && !defined(NoDbgRegParms)
# define NoDbgRegParms __attribute__ ((regparm (0)))
#endif
#if !defined(NoDbgRegParms)
# define NoDbgRegParms /*empty*/
#endif
Here, remove the first #if…#endif.
Although this doesn’t make the issue go away, it might help get a working VM.
Cheers,
Max

Obviously the first thing I tried was building a debug vm to see if I could work out what is wrong but that wonât even come close to building. The log is full of exciting things like -
