Consider the following files, test.h and test.m:
test.h:
-------
/* Contributed by Nicola Pero - Tue Jan 16 04:09:06 GMT 2007 */
#include <objc/objc.h>
#include <objc/Object.h>
@interface TestClass : Object
+ (int) test;
@end
test.m:
-------
#include "test.h"
@implementation TestClass
+ (int) test
{
return 0;
}
@end
int main (void)
{
return [TestClass test];
}
My compiler is 4.1.1 20070105 (Red Hat 4.1.1-51).
If I compile the files in the standard way --
gcc test.m -lobjc
it all works.
If I first precompile test.h
gcc -x objective-c-header test.h
I get the test.h.gch file, which looks ok, but then compiling fails --
gcc test.m -lobjc
test.m:4: warning: cannot find interface declaration for
�TestClass�
test.m:4: error: redefinition of �struct TestClass�
(compilation aborts)
(I also got a compiler internal error once)
Using the -H option to gcc you can indeed confirm that compilation fails iff
the
precompiled ObjC header is used.
It seems that ObjC class declarations in ObjC headers are not read correctly/at
all from precompiled headers (C stuff works fine instead!). Very
disappointing. :-(
I hope I'm missing an option / something, else it's a bug that needs fixing :-(
Thanks

Confirmed, a regression from 4.0.4 where this worked.
I will look into this more soon.

Once fixed, it might be worthwhile adding testcases for this then ? :-)

Yes and I am going to try to do that also.

Well this was caused by the objective-C++ merge. This is also a classic
example of why hashing on pointer values is not a good idea.
Working on a fix, should also simplify the code :).

I have a full fix and a semi working testsuite (semi working mean it will work
for non remote testing).
This is just a good example of when you should not use pointer hashing,
especially when there is already a hash for identifiers.
