The Foundation framework is the >basic equivalent of the C library, without it, you can't do anything. No, it's not. The standard C library is specified by the C language specification. Foundation is not specified by the objC language specification, it's specified by NextStep. It's more like saying "I want to use C, but not glib".

Linking with -objc solved that, but now I got a warning: /usr/bin/ld: warning: libobjc.so.lf2, needed by /usr/lib/gcc/powerpc-linux-gnu/4.1.3/../../../../lib/libFoundation.so, may conflict with libobjc.so.1 Perhaps this can be fixed by removing the dependency on libFoundation? Also, running the program does not work: You must call +[NSProcessInfo initializeWithArguments:count:environment:] in main() (Again this is caused by libFoundation, I think.)

How do I use the Objective-C bindings? When trying to build a simple example program, I get: chiyo:/tmp% gcc -o test test.m -lFoundation /tmp/ccowH8qL.o: In function `main': test.m:(.text+0x1c0): undefined reference to `really_free_svalue' /tmp/ccowH8qL.o:(.data+0x334): undefined reference to `__objc_class_name_OCPikeInterpreter' collect2: ld returned 1 exit status chiyo:/tmp% Ok, I obviously need to create some library. But how? The only part of the build system which touches "OCPikeInterpreter" appears to be the rule "framework", but making framework does not work: chiyo:~/Pike/7.7/build/linux-2.6.22-12-powerpc-ppc% make framework Compiling OCPikeInterpreter.m make[1]: Entering directory `/home/marcus/Pike/7.7/build/linux-2.6.22-12-powerpc-ppc' make[1]: Leaving directory `/home/marcus/Pike/7.7/build/linux-2.6.22-12-powerpc-ppc' make[1]: Entering directory `/home/marcus/Pike/7.7/build/linux-2.6.22-12-powerpc-ppc' make[1]: Leaving directory `/home/marcus/Pike/7.7/build/linux-2.6.22-12-powerpc-ppc' Linking Pike.framework gcc: Cocoa: No such file or directory gcc: dynamic_lookup: No such file or directory gcc: 7.7: No such file or directory gcc: @executable_path/../Frameworks/Pike.framework/Pike: No such file or directory gcc: unrecognized option '-current_version' make: *** [framework] Error 1 chiyo:~/Pike/7.7/build/linux-2.6.22-12-powerpc-ppc% I think this needs some work before it can go into 7.8.

As you can see from the sudden spree of checkins we've had another meeting in Linköping (though the initial objective had nothing to do with Pike, the discussion turned in that direction, and we would be stupid to not take notes...) While many of the items are simply bugfixes or incomplete features, there were a few items that dealt with changes that impact the language on a fundamental level. We revisited the "static" discussion and some good arguments were made both for the functionality of static (as in "moved out one scope") and against it. The consensus we had was to directly implement "protected" to do what "static" does today. Previously "protected" did nothing. This has been committed. As next move we would like to implement "shared" as a new keyword that does the "declare in outter scope" thing and to make "static" as deprecated (giving a warning when used). While on the subject of keywords we thought it would be a good idea to also mark "nomask" as deprecated ("final" does the same job). We also want to add "deprecated" as a keyword to be able to mark non-recommended parts of the interface as such. The idea is to tie deprecated into the type system so that it can not only be used on entire functions, but also on specific arguments. A new and annoyingly long #pragma statement to silence deprecation warnings was suggested.

A snapshot is now available at <http://mc.pp.se/gkdrill.pike>. You need the file /usr/share/edict/kanjidic for the program to work.

It's missing lots of functionality. Mostly in the area of selecting the set of kanji to be quizzed on. But the basic stuff works.

GTK2 examples

I got a request the other day for some examples of using the GTK2 module that go beyond "hello world". I only have GTK(1) code; does anyone else have anything that might satisfy an intrepid developer? Bill

Snapshot tarballs and packaging/debian
by Magnus Holmgren, FR Ryd (Nu med m�l och syfte) ＠ Pike (-) developers forum 03 Oct '07

I have a few questions relating to pike in Debian (as you may know, the previous maintainer has retired from Debian and orphaned his packages). I've figured out that one can get a fresh tarball from http://pike.ida.liu.se/generated/pikefarm/packages/7.6/latest. What's the difference between that and checking out from CVS and running "make source" (which is what I suspect Marek has done), if any? Is there any archive of such tarballs except for the official releases? How did the packaging/debian subdirectory originally come to be? Do you synchronize with the Debian package yourself or has Marek been sending you patches? I see that export.pike adds new records to packaging/debian/changelog. AFAICT, export.pike --tag first increments the build number (to an even number, typically), then tags, then increment the build number again, so that an even build number represents a known state of the source, whereas an odd build number can include any number of commits inbetween.

I don't think we've ever changed the API between x.even.y, but it of course happens in e.g. Pike 7.7.

Wait, there's http://pike.ida.liu.se/download/pub/pike/beta/. Neat. But there's no 7.7 there.
