Follow-up Comment #2, bug #46443 (project make):
I started to go down the path of changing job_next_command and new_job where
allocated_variable_expand_for_file gets called, but quickly came to the
conclusion that altering file->fileinfo.lineno wasn't the way to go at all.
The simplest approach I've found for fixing this is to change gmk_floc:
typedef struct
{
const char *filenm;
unsigned long lineno;
+ unsigned long offset;
} gmk_floc;
... then make the following modifications:
job.c, around line 1899:
/* Finally, expand the line. */
+ cmds->fileinfo.offset = i;
lines[i] = allocated_variable_expand_for_file (cmds->command_lines[i],
file );
}
+ cmds->fileinfo.offset = 0;
c->command_lines = lines;
job.c, around line 2099:
}
+ child->file->cmds->fileinfo.offset = child->command_line;
return 1;
}
Then at the very least change **some** of the following uses of (...)->lineno
to add (...)->offset:
* job.c, child_error()
* job.c, new_job(), during tracing around line 2052
* commands.c, print_commands()
* file.c, line 273 in rehash_file()
* function.c, line 1712
* variable.c, line 1629
... and lastly (I think), in read.c and rule.c: change all initializations of
"lineno" to also initialize "offset".
