Still running into issues on ref11-amd64:
cc1: error: unrecognized command line option "-m64"
dtrace: failed to compile script
/scratch/tmp/ngie/svn/cddl/contrib/opensolaris/cmd/dtrace/test/tst/common/json/usdt.d:
Preprocessor failed to process input program

*** [usdt.h] Error code 1
Let’s see what happens if I use make buildenv
$ env MAKEOBJDIRPREFIX=/scratch/tmp/$USER/obj make buildenv TARGET=mips
TARGET_ARCH=mips
Entering world for mips:mips
$ make -VMAKEOBJDIRPREFIX
/scratch/tmp/ngie/obj/mips.mips
$ which dtrace
/usr/sbin/dtrace
Uh… yeah… running the copy from the build host is no bueno. So, that root
causes that issue. I’ll file a bug for that (dtrace needs to be built as a
bootstrap/cross tool). The -m64 issue is because it’s compiled for amd64 and is
running arguments that are only supposed to “work” for x86 platforms (in
reality, there’s also no reason why -m32/-m64 need to be passed to
${CC}/${CPP}):
1256 #ifdef illumos
1257 #ifdef __x86
1258 /*
1259 * On x86 systems, __i386 is defined for <sys/isa_defs.h> for
32-bit
1260 * compiles and __amd64 is defined for 64-bit compiles. Unlike
SPARC,
1261 * they are defined exclusive of one another (see PSARC 2004/619).
1262 */
1263 if (dtp->dt_conf.dtc_ctfmodel == CTF_MODEL_LP64) {
1264 if (dt_cpp_add_arg(dtp, "-D__amd64") == NULL)
1265 return (set_open_errno(dtp, errp, EDT_NOMEM));
1266 } else {
1267 if (dt_cpp_add_arg(dtp, "-D__i386") == NULL)
1268 return (set_open_errno(dtp, errp, EDT_NOMEM));
1269 }
1270 #endif
1271 #else
1272 #if defined(__amd64__) || defined(__i386__)
1273 if (dtp->dt_conf.dtc_ctfmodel == CTF_MODEL_LP64) {
1274 if (dt_cpp_add_arg(dtp, "-m64") == NULL)
1275 return (set_open_errno(dtp, errp, EDT_NOMEM));
1276 } else {
1277 if (dt_cpp_add_arg(dtp, "-m32") == NULL)
1278 return (set_open_errno(dtp, errp, EDT_NOMEM));
1279 }
1280 #endif
1281 #endif
As for why the original issue occurred on my VM (which was the powerpc:powerpc
case), I’m not sure yet. I’m working on figuring that out.
Thanks!
