some observations on the build process
by Martin Bähr 19 May '04

hi, when building pike 7.6 from cvs i noticed a few things that could be improved: after configure a summary of what was detected is shown. but when you just run make as suggested then you never see that summary because it gets buried in the compile outbut following it. hence it would be nice to show that summary after a complete make run as well. after finding that a lot of libs were missing to build GL and all that i found that after installing them neither make force_autoconfig nor make force_configure not even make clean would do anything to update the findings. i had to remove the whole build tree to get the new libs detected. greetings, martin.

Pike @ win32
by Marcus Agehall (Scanian) ＠ Pike (-) developers forum 19 May '04

19 May '04

I've just committed an initial patch that allows Pike to be compiled using mingw32. To compile pike using mingw32, you will have to do the following: 1) Install the latest mingw32-dist 2) Install Msys 3) Install the mingw Win32 API update 4) Install GMP (either from source or bin package) 5) Install Nettle (untested! I've been using --without-nettle for the time beeing...) 6) Get a Pike 7.7 source snapshot (or build one yourself). Building from CVS under mingw32 seems to break due to some cr/lf problem, so build the source-dist on a unix box. 7) Set the PIKE_PATH_TRANSLATE to some sed-command which translates the master-paths from you MSYS installation to the regular NT-CMD filesystem(*). 8) Do "make configure" to configure your buildtree. 9) Do "make" do build pike. 10) (optional) Do "make verify". This will fail, the hard way.. ;( 11) You should now have a pike which is usable to some extent. I havn't tested it much, but I've done some simple tests and it seems to hold up fairly well. (*) I build from my home-dir, /home/SSS668. To create a working master, I need to translate that path to c:/msys/1.0/home/SSS668. You need to do the same using some creative sed-command or accept that your build will fail when it attepmts to build post_modules. You can modify the master manually if you like. Look for the ¤-sign to find what places to modify. So, there it is. Now you should know what you need to build. I believe that Mingw32 is the easiest way to get Pike to compile on Win32. However, I'm not so certain it is the best choice since there seems to be quite a few compatibility issues between mingw32 and the win32 api (as MS provides it). I have access to both at work and they do not match in several places. I believe that we should try to get Pike to work with mingw first, and then start working towards MSVC native compilation. However, there will still be the problem of configuring the build. It may be that we always will need a msys-layer to run configure.

> I think, like many others, that there are too complex macros in Pike and > that it's a big problem for code readibility. I guess you're talking of things like the block_alloc system, fsort.h, the volymous macros for doing string stuff once for each string width, and the undisputed king of the hill: The interpret_functions.h macro system. Things like THREADS_DISALLOW is just an ordinary macro and can hardly be considered a readability problem. I know what you mean; I got fairly frustrated too the first time I tried to grep through the source for the definition of get_marker and couldn't find it anywhere. Still, once you've groked how it works it's damn handy. Some of the string processing stuff could probably have been written without macros and instead accept the performance hit, and it got to be possible to clean up the interpret_functions.h stuff somehow. Using macros to at compile time choose between a heap of separate functions and a giant case is a bit over the edge imho; trusting function inlining just a little would have made it a lot simpler. But apart from that, you have to consider what the alternatives would be before dissing it (which doesn't imply that I think every single remaining macro is altogether nice and tidy, though). For e.g. block_alloc and fsort, I can only think of C++ templates as being able to improve it in any way. / Martin Stjernholm, Roxen IS Previous text: >2004-05-18 12:39: >Subject: Re: Nettle cmod segfault >-------------------------------------------------------------------- >Martin Stjernholm, Roxen IS @ Pike developers forum wrote: >>>As we are speaking of that, wouldn't it be possible to make this macros >>>with a little less code in it (and generally in macros used in Pike)? >> >> >> Possible - yes.

What about Judy
by Sten (Android) Eriksson (of Borg) ＠ Pike (-) developers forum 17 May '04

17 May '04

I just browsed a couple of old sweetcode.org articles and stumbled onto the "Judy functions" located at <http://judy.sourceforge.net/>. Snippet from sweetcode.org's description: "Judy is an implementation of a sorted associative array in C. All reasonable associative array implementations have O(log N) insert and lookup complexity, but the constant factor for Judy is very much smaller than other widely used implementations (several times faster than STL's "map" and twice as fast as SGI's "hash_map", in my trivial benchmarks)." This made me think of how beneficial it would be to Pike. There is a lot of doc's at the site, man pages, pdf-documents with both brief and in-depth descriptions and analysis. On associative arrays: <http://judy.sourceforge.net/application/judysl.pdf> On scalable hashing: <http://judy.sourceforge.net/application/Judy_hashing.pdf>

Pike 7.6.6 building problem

15 May '04

Hello, When using the Pike tarball on ftp://pike.ida.liu.se/pub/pike/latest-stable/Pike-v7.6.6.tar.gz: checking for nettle_md5_init in -lnettle... no checking for md5_init in -lnettle... no Bundle nettle not available in /usr/local/src/Pike-v7.6.6/bundles. configure: error: Cannot compile --with-nettle without the Nettle library. It is highly recommended that you install a working Nettle library on your system as that will add features to Pike required by many applications. These features include ciphers, hash algorithms and random generators. If you know that you do not need cryptographic functions, you can re-run configure with the option --without-nettle instead. configure: error: /bin/bash -norc '/usr/local/src/Pike-v7.6.6/src/post_modules/Nettle/configure' failed for Nettle sed: can't read confdefs.h: No such file or directory configure: error: /bin/bash -norc '/usr/local/src/Pike-v7.6.6/src/post_modules/configure' failed for post_modules make: *** [configure] Error 1 david@camas:/usr/local/src/Pike-v7.6.6$ ls /usr/local/src/Pike-v7.6.6/bundles gmp.txt nettle-1.10.ptar.gz nettle.txt Shouldn't the file be named nettle-1.10.tar.gz instead of nettle-1.10.ptar.gz ? / David

get_all_args

There is no get_all_args symbol for functions. Given that it isn't on purpose and that it should be possible to get a function, what symbols should be used?

discard strings in mid-air

Is do_really_free_pike_string the correct method to discard pike strings that has not been finished (i.e. begin_shared_string has been called, but not end_share_string)?
