Hey all,

I have taken in Tim's patches except for the file handle stuff.  I am in
the process of setting up another machine so that I can install the latest
gcc.  I will redesign the omni for the file stuff.

Thanks,

Mark

Ok.  I have put the latest files in cvs.  It does compile now with the
command:
      make CFLAGS="-march=i386 -mcpu=i686 -Wall -DGCC_VER_3"

Now, all I need is a way to determine which version of the compiler that I
am using instead of using
an external define (GCC_VER_3).

Thanks Tim for your help.

Excellent.  I have pulled the latest and am building.

The preprocessor macro __GNUC__ contains the major version number of
the compiler.  __GNUC_MINOR__ contains the minor version number of the
compiler, as you'd expect.  So you can replace '#ifdef GCC_VER_3' with
'#if defined(__GNUC__) && (__GNUC__ >= 3)', I think.

Unfortunately this isn't sufficient. The default compiler on Debian woody calls itself 2.95.4. So this check isn't sufficient. However, building current cvs with -DGCC_VER_3 does repair the link problems I was seeing 'out of the box' with 2.95.4. Just so we're all on the same page, this particular trouble looks like:

make[1]: Entering directory `/home/giles/projects/ghostscript/omni/XMLParser'
c++ -o parser MyErrorHandler.o OmniDomParser.o Main.o -L .. -lomni -lxml -L/usr/lib -rdynamic -lgmodule -lglib -ldl
../libomni.so: undefined reference to `getEnumeration__Q312OmniPDCProxy38getCurrentResolution__12OmniPDCProxy.0_22OmniPDCProxyResolution.987'
[...and many similar undefined references]

Building with DEBUG=1 also remedied this.

The (__GNUC__ > 3) check does work with gcc-3.0, but there appear to additional source gotchas:

g++-3.0 -Wall -fPIC -rdynamic -O3  -DRETAIL=1  -I . -I hppcl3 -I/usr/include/glib-1.2 -I/usr/lib/glib/include -c DeviceBlitter.cpp
In file included from DeviceBlitter.cpp:19:
Device.hpp:141: type specifier omitted for parameter
Device.hpp:141: parse error before `)' token
make: *** [DeviceBlitter.o] Error 1

I hope we can get this cleared up and building more portably soon.

Cheers,
