configure on solaris 2.7

[havard.tveite@…]

Using todays CVS snapshot, the following problems arise when running configure on my solaris 2.7 system:

./configure --help
./configure: syntax error at line 1622: `CAPI_VERSION_MAJOR=$' unexpected

If I remove:

$(($CAPI_INTERFACE_CURRENT-$CAPI_INTERFACE_AGE))

and replace it with either 1 (the difference), or

$CAPI_INTERFACE_CURRENT-$CAPI_INTERFACE_AGE

configure seems to work as expected.

I found that this problem also applies to version 2.2.3, but in 2.2.3 there was also another line with the same syntax that had to be fixed

$var-$val would result in the "4-3" string with a bourne shell. Can you find another syntax for arithmetics ?
Could you try $((4-3)) just to test ?

[havard.tveite@…]

OK.  I only found out that something was wrong, and reported it.  I have now found that the Solaris ksh has arithmetic expansion of the type used in configure ( "$(())" ), but Solaris sh does not have it .
I do not know the portable way to do arithetic in shell programming, but I have seen expr mentioned, so perhaps the following is more portable:
CAPI_VERSION_MAJOR=`(expr $CAPI_INTERFACE_CURRENT - $CAPI_INTERFACE_AGE)`

Does this work ?

a=4
b=3
c=`expr $a - $b`
echo $c

[havard.tveite@…]

Yes,

CAPI_VERSION_MAJOR=`expr $CAPI_INTERFACE_CURRENT - $CAPI_INTERFACE_AGE`

also works.

Thank you, committed the patch in TRUNK. please confirm it works now.

[havard.tveite@…]

It works now.
