Problem to configure --with-ns with GNUstep

Problem to configure --with-ns with GNUstep

[Germán Arias]

OK, now I have gcc 4.6 and I'm back to try emacs with gnustep. But now,
I'm unable to configure emacs. With 

./configure --with-ns --with-gnustep-conf=/etc/GNUstep/GNUstep.conf

I get the error:

checking AppKit/AppKit.h usability... no
checking AppKit/AppKit.h presence... no
checking for AppKit/AppKit.h... no
configure: error: `--with-ns' was specified, but the include
  files are missing or cannot be compiled

The file GNUstep.conf is read, and the path to AppKit/AppKit.h is found
successfully (I checked). But then the function
"ac_fn_c_check_header_mongrel" return errors. So, adding flags
(CPPFLAGS=-I/...) don't solve the problem, because even when the paths
are right, the function "ac_fn_c_check_header_mongrel" return errors.
Since I'm not an expert in scripts any advice is appreciated. Thanks.

Hello.

Check your config.log.  There you can see the error in detail.

Thanks. The error is:

/usr/GNUstep/Local/Library/Headers/Foundation/NSException.h:42:2: error:
#error The current setting for native-objc-exceptions does not match
that of gnustep-base ... please correct this.

Can I change this configuration on GCC, or I need rebuild 
gnustep-base with special configuration?

Hi.

You can try to take out -fobjc-exception from the gcc command.
If you don't have it, try to add it.

This is the explanation that Richard (gnustep-base maintainer) give me
about this problem:

For the moment, I solved the problem checking the value of
BASE_NATIVE_OBJC_EXCEPTIONS, defined at header "GNUstepBase/GSConfig.h",
and declaring _NATIVE_OBJC_EXCEPTIONS in "configure" with that value. Of
course, configure should read that header to see the right value that
depend of each user.
