&gt; I've tried both before and after the special generated flags code.

Hi!



If you are on any platform for which wx-config may be used (which is

all but Windows, I think), then the "Comma-separated C++ search path"

description does not apply. Before the advent of wx-config, that's how

DB worked, but you cannot do this with wx-config use. What you need to

do is place your include before or after %AUTO% separated by a space,

and it must be in the compiler's switch format. For GCC and most

UNIX/Linux systems this will be a -I switch. It is also a good idea to

place the path in quotes. For your example, it might be:



%AUTO% -I"&lt;path to OpenEXR includes&gt;"

     Compile error building Linux lib with
DB makefile

Porting an app to Linux I have to make a static lib to link
to the DB  
app.
This was a windows support only app, so no unix makefile.
I have already built it on the Mac using Xcode to just grab
all the  
source files and make a static lib. Worked fine.

On Linux, I used DB to make a makefile with all the source
files,  
then hand altered to just leave the compile for each source
file and  
added the ar command instead of the g++ link step.

But none of the source files will compile. The first ones
are the  
zlib files that I have compiled into many apps on windows
and the  
Mac. Compiling the first one gives me this error:


grnbriarDads-linux:/Devel/cximage580_src$   make -f
MakefileMine
g++ -c -o ReleaseGTK2/adler32.o -I"./CxImage"
-I"./jpeg" -I"./tiff" - 
I"./zlib"   -O -Wall zlib/adler32.c
zlib/adler32.c:21: error: ‚uLong adler32‚ redeclared as
different  
kind of symbol
zlib/zlib.h:821: error: previous declaration of ‚uLong
adler32(uLong,  
const Bytef*, uInt)‚
zlib/adler32.c:21: error: ‚adler‚ was not declared in this
scope
zlib/adler32.c:21: error: ‚buf‚ was not declared in this
scope
zlib/adler32.c:21: error: ‚len‚ was not declared in this
scope
zlib/adler32.c:25: error: expected unqualified-id before ‚{‚
token

zlib.h:821
ZEXTERN uLong ZEXPORT adler32 OF((uLong adler, const Bytef
*buf, uInt  
len));

adler32.c:21
uLong ZEXPORT adler32(adler, buf, len)
     uLong adler;
     const Bytef *buf;
     uInt len;
{

from zconf.h
#  define ZEXPORT
#  define ZEXTERN extern

#    define OF(args)  args


Looks the same to me!
Compiles everywhere else fine.
Is there an additional flag I need to use old style C params
in a .c  
file with g++??
