[Simh] Problem with default builds

Fri Aug 7 12:47:14 EDT 2015

Sorry folks.  The problem occurs anywhere the SWMASK is used in a static initializer.  I’ve reverted the recent change.

The change was initially thought to be benign and attempted to allows for the simh source to be useful on systems with other than ASCII character sets (i.e. EBCDIC).  There are other issues with simulators running on hosts with EBCDIC character sets which are unrelated to the source code.  If/when those are also addressed, we’ll revisit how to solve the non ASCII source code issue as well.

Subject [Simh] Problem with default builds

Another build error.   Unfortunately, I do not have the knowledge
to fix it myself.

Today, 6-Aug-2015, I downloaded the current simh-master.zip from
github.

My host is an Alpha XP1000 running VMS v8.4

Using MMK from the VMS Freeware 8 CD, I tried to do a default
build of all SIMH simulators.   All went well until the build of
ID16-AXP.OLB Library.   At that point I got the error:

    { "DP", SWMASK ('F'), 9, 0x32, o_DP0, o_DPF },
............^
%CC-E-NEEDCONSTEXPR, In the initializer for dboot_tab[1].sw,
"sim_swmask(...)" is not constant, but occurs in a context that requires a constant
expression.
at line number 318 in file DKA200:[FRISBIE.SIMH.SIMH-MASTER.INTERDATA]ID16_DBOOT.C;4
%MMK-F-ERRUPD, error status %X10B91262 occurred when updating
target SYS$DISK:[.BIN.VMS.LIB]ID16-AXP.OLB

The log of the build (with lots of successful stuff snipped)
follows below.

Thanks,
Alan Frisbie
