RE: Trying to build PERL 5.22.3RC1 on OpenVMS VAX V7.3 with some issues...

Hi Craig,

> Why?
Because I like the VAX.  I also have the emulator running at just under =
24 times the speed of a VAX 780.  I'm also working on an emulator for =
the Alpha.  The VAX may have been discontinued, but there are many still =
out there and ignoring them is just wrong.

It appears that /OPT=3DNODISJOINT does appear to work successfully.

Thanks,

~Jon.

Why?  The VAX architecture was discontinued sixteen years ago.  If you =
succeed it will take days and days to do the build.  There have been an =
increasing number of features that won=E2=80=99t work right on an ODS-2 =
disk.  So, it=E2=80=99s an uphill battle, and not worth the effort when =
you can get an Alpha emulator or a cheap Itanium on eBay.

proceeding (CONFIGURE.COM, DESCRIP_MMS.TEMPLATE, and MAKFILE.PL in =
DYNALOADER needed some changes).  I=E2=80=99m now at the point where MD5 =
is compiling and though it shows CPU time being takeng up, there is no =
I/O occurring and the compilation never returns.  The compile =
I=E2=80=99m using is Compaq (DEC) C V6.4.  Has anyone else had this =
issue?  I=E2=80=99m not sure how to best debug it.  Any help would be =
appreciated.

The optimizer on that old compiler gets confused but compiling with =
/Optimize=3D(NODISJOINT) has been reported to do the trick.

There is a patch to do that here in this ticket:
