You will have to preprocess the __LINE__ entries before running Pro*C. Here is a quick little perl script that can do this. It is invoked as:

 preline <your_file_name.x >your_file_name.pc

where your_file_name.x has the __LINE__ tokens. This should be easy to put into a make script.

oops, the previous replaced "__LINE__" with "line: ##" If you got the last message please use this script instead.

Here's the code to preline:

--------------------------cut here-------------------
#!/usr/bin/perl
##################
#
# preline
# ed prochak Oct. 1998
#
# This perl script replaces __LINE__

# with source file line number.
#

while ( $line = <> )
{
  $n++;
  $line =~ s/__LINE__/$n/g ;
  print $line
}
