Subject: cross-compile mvme162

Hi

The difference between compiling a mvme167 and compiling a mvme162 is that the
former uses -m68040 option while the latter one uses -msoft-float option.

When I loaded  base/bin/mv162/iocCore into a mvme162, I got the error messge as
following:

ld < targetmv162/iocCore
undefined symbol: ___eqdf2
undefined symbol: ___gtdf2
undefined symbol: ___ltdf2
undefined symbol: ___floatsidf
undefined symbol: ___adddf3
undefined symbol: ___divdf3
undefined symbol: ___floatsisf
undefined symbol: ___addsf3
 ......
ld error: error reading file (errno = 0x1c0001)

When I loaded base/bin/mv167/iocCore,drvSup, recSup, devSup and a simple
database into a mvme162, it didn't give me any error message, but the IOC hang.
(drvSup and devSup caused it)

I don't have any problem to load mv167/stuff into a mvme167.

Could anybody give me a help? Thanks a lot.

Dong
