RE: QuickScan and exported files....

[Greg Spencer]

Eric, try removing the "<" and ">" around Ecm_err.h and replacing them
with '"'s.

Cons (and the compiler) treat these differently, and that may make all
the difference for you.

                        -Greg.

Subject: QuickScan and exported files....


I'm running into a problem using Cons to build IDL files that include
files
outside the current directory.  In particular, the header file isn't
getting
copied to the export directory before the IDL compiler is getting
called.

The details are as follows:

I have a top level Inc directory that contains a file Ecm_err.h.

In another directory, I have a file ECMWrapperS3.idl that has the
following:
// This file will be processed by the MIDL tool to
// produce the type library (ECMWrapperS3.tlb) and marshalling code.
#include <Ecm_err.h>

import "oaidl.idl";
import "ocidl.idl";

<lots of IDL follows>

My IDL generator function contains the following call to QuickScan:

    $env->QuickScan(
                sub { my(@includes); 
                        do {
                                push (@includes, $3 ) 
                                        if
/^\s*(#include|import)\s+(\")(.+)(\")/ && $3 
                        } 
                        while <SCAN> ;
                        @includes 
                } ,
                "$args{IDL}",
                "$env->{CPPPATH}" 
    );

$env->{CPPPATH} is
"build\debug\ECMWra~1\ECMWrapperS3\res;#export/debug/include;#export/deb
ug/i
nclude".

Inc/Conscript has

# Put Headers Here
@HDRS = qw(
        Ecm_err.h
        Ecm_all.h
        Ecm.h
        Add.h
        Add_err.h
        );

Install $CONS $INCLUDE, @HDRS;

If I print @includes in the QuickScan call, I get "Ecm_err.h oaidl.idl
ocidl.idl"
So, as you can see, everything *looks* like it ought to be copying
Inc/Ecm_err.h to #export/debug/include, where the IDL compiler can find
it.
Instead, all I get is this:
D:\tropics\Ver1.0>cons

I can hack it into working (by manually including the inc directory),
but I
don't think I should have to do this.

Any suggestions?  (I'm running Tony Kolarik's modified version of Cons
1.8.)
