Platform : Solaris 10 Update 6 64-bit X86 with GCC 4.1.2
Greetings All\,
I have just tried to build perl5 from the git repo (faa13f98b5438d7d2712a2578895829787af9ff5) for Solaris with DTrace Support enabled. The build failed due to missing dependencies. It appears that the required object files are not yet built at the stage of the build where perldtrace.o is generated from perldtrace.d.
I tried adding dependencies to perldtrace.o to build the required objects before perldtrace.o\, but that was not successful (see below).
The second approach was simply to remove those object from the list of files passed to the 'dtrace -G' command. This approach works and all test harness pass :-)
Is it the absolute right way to do this? Honestly I can't be sure\, dtrace does NOT seem to modify any existing object files passed to it\, but take notice of the ELF CLASS of the objects passed to it\, saving us passing -32 or -64 explicitly.

PS: Additionally\, the following may assist people trying to compile perl 5.12.0 on Solaris 10 with GCC 4.1.2 or possibly other versions of GCC. The generated header file\, perldtrace.h\, includes an #if _DTRACE_VERSION\, which is used to determine if DTrace is available and its major version number. It gets this via '#include \<unistd.h>'\, which gets the real definition from \<sys/feature_tests.h>. Unfortunately\, my version of GCC has a GCC 'fixincludes' generated version of \<sys/feature_tests.h> which misses that definition. (Probably because GCC was build on S10U3 and I'm now running S10U6). Regardless\, a successful compile with DTrace enabled did not produce any DTrace functionality. Adding -Accflags='-D_DTRACE_VERSION=1' to the Configure line is a temporary workaround (ok hack) which worked for me.
