Hi Randy,
re: REMAP2-created AREA files on Solaris 5.11 and CentOS 5.5 x86_64

Thanks.
I think that there is a good clue in these files that will help you figure
out where the execution of the code on the different OSes differs.
In order to compare the AREA files you sent, I did the following:
AREA9107_Solaris -> $MCDATA/AREA9107
AREA9107_CentosOS -> $MCDATA/AREA9108
Next, I listed out the header values in the two AREA files using LWU:
First the AREA created on Solaris:

Notice that the listings are identical EXCEPT for words 76-78 and
96-98, inclusive. Something in your code is writing "is too small"
and "is too big" into the AREA file header created on Solaris.
I did a 'grep' for "is too small" in all C files in the Unidata
McIDAS-X distribution, and I found three occurrences; I am
guessing that the operative ones are in argerror.c and
m0navget.c:
argerror.c:
/* Define messages for standard arg-fetching error reasons,
corresponding to the following nnnX statuses:
nnn[1] nnn[2] nnn[3] nnn[4] nnn[5]
ARG_INVALID, ARG_INVDEC, ARG_ILLEGAL, ARG_LT, ARG_GT */
char why[10][80] = {
"", /* 0 */
"has invalid xxxxxxx form", /* 1 */
"can't have a fraction", /* 2 */
"exceeds system limits", /* 3 */
"is too small", /* 4 */
"is too big", /* 5 */
"", /* 6 */
"", /* 7 */
"", /* 8 */
"" /* 9 */
};
m0navget.c:
istat = M0swbytnav( mxwds, navblock );
if( istat < 0 ) {
Mcdprintf("M0ReadNavBlock() internal error:\n");
Mcdprintf("Passed %d words to M0swbytnav(), and\n", mxwds);
Mcdprintf("it says that this is too small.\n");
Mcdprintf("Programmer must enlarge buffer in caller of "
"M0ReadNavBlock() or m0nvblk()\n");
return BAD_NAVBLOCK_LEN;
}
Here is how I would proceed:
- rerun the REMAP2 invocation on both OSes, but this time specify the DEV=CCC
keyword so that debug messages will be printed (Mcdprintf is a debug print
statement)
This may (or may not) give you enough clues to track down the
discrepancy.
Comment:
- it is VERY interesting that if you change the "is too small" and
"is too big" values in the AREA header values created under Solaris,
the IMGLIST listing becomes identical to that for the AREA created under
CentOS:
