Nettle
by Martin Nilsson (saturator) ＠ Pike (-) developers forum 26 Feb '04

I PUSHED THE BUTTON. Now the _Crypto module isn't used (though still built). That means that you'll need Nettle installed to use any parts of Pike that uses Crypto.

7.4.44
by Martin Nilsson (saturator) ＠ Pike (-) developers forum 26 Feb '04

26 Feb '04

Peter and I have been working hard with resolving some NT problems and have now managed to create a new NT dist with pretty much everything except GLUT. 7.4.44 source dist and windows dist are available in FTP. Release notes at http://pike.ida.liu.se/download/notes/7.4.44.xml We'll release it more publicly when we have binary dists for more platforms. Please help out with good binary dists.

Pike 7.5 - CVS installation problem

Hello, When trying to install Pike 7.5 - CVS on FreeBSD 4.3, I got this error: %make install /home/david/Pike/7.5/src/pike -DNOT_INSTALLED -DPRECOMPILED_SEARCH_MORE -m/home/david/Pike/7.5/src/master.pike -x extract_autodoc -q --srcdir=/home/david/Pike/7.5/src --imgsrc=/home/david/Pike/7.5/refdoc/src_images --builddir=doc_build/src --imgdir=doc_build/images Bad argument 1.

Embedding Pike into C/C++ game
by Fredrik (Naranek) Hubinette (Real Build Master) ＠ Pike (-) developers forum 25 Feb '04

25 Feb '04

In my oppinion, pike would have to be a lot more modular to become popular in games. Basically, you would need to chop pike into pieces that can be linked individually. In my mind, those pieces would be: 1) The interpreter Capable or running pike-code, but provides only the most basic functions needed to manipulate data types. The interpreter does not provide a way to load code into memory. 2) The Compiler Capable of compiling pike-code to in-memory code 3) Object loader (could be more than one) Capable of loading pre-compiled pike code into memory. 4) Function library. (or libraries) Provides all the functions needed to make up a complete Pike. 5) Pike executable Uses all of the above libraries to run Pike programs. Apart from this, all identifiers that don't start with 'Pike' should be fixed to make Pike more embedding-friendly. / Fredrik (Naranek) Hubinette (Real Build Master) Previous text: >2004-02-23 16:54: >Subject: Embedding Pike into C/C++ game >-------------------------------------------------------------------- >I forgot some things in my original email.

XMLRPC patch for 7.2
by David Gourdelier 25 Feb '04

25 Feb '04

Hello, I have a patch for Pike 7.2 XMLRPC. The spec at http://www.xml-rpc.org/ says the <value> element can contain <string>, <array> and so on but can also contain a PCDATA by itself ("If no type is indicated, the type is string."). This wasn't set in XMLRPC.pmod and this is used by some client like XML-RPC Apache project one. Here is the patch: on Feb 23 16:38:40 2004 @@ -137,7 +137,7 @@ <!ELEMENT params (param*)> <!ELEMENT param (value)> - <!ELEMENT value (boolean|i4|int|double|string|base64| + <!ELEMENT value (#PCDATA|boolean|i4|int|double|string|base64| array|struct|dateTime.iso8601)> <!ELEMENT boolean (#PCDATA)> @@ -231,6 +231,8 @@ // seems to assume localtime). return Calendar.parse("%dT%h:%m:%s", data*"") || magic_zero; + // the spec says that the default is string inside value + default: return data*""; } error("Unknown element %O.\n", name); case "error": / David

configure

How can I tell configure that I want to use the ar/as/gcc/ld/nm/etc binaries from /foo/bar instead of the system-ones?

PIKE

How do I get Pike to use another pike then /usr/local/bin/pike? Setting PIKE, USE_PIKE or --with-pike doesn't seem to help. config.info reports: | pike............ /usr/local/bin/pike-7.5 but: | precompile: /usr/local/bin/pike /home/mirar/pike/bin/precompile.pike /home/mirar/pike/src/modules/Gmp/mpq.cmod (method=QQQQQ) | /home/mirar/pike/bin/precompile.pike:2121:Indexing on illegal type. | Pike: Failed to compile script: | Compilation failed. | | Failed to find a Pike executable that could run /home/mirar/pike/bin/precompile.pike.

Bad number of identifiers in inherit: 2 != 3
by Johan Sundstr�m (Achtung Liebe!) ＠ Pike (-) developers forum 24 Feb '04

24 Feb '04

After the recent changes to Parser.RCS, I see a warning /usr/local/pike/7.5.19/lib/modules/Parser.pmod/_parser.pmod.o:-: Warning: Decode failed: Error while decoding program(/usr/local/pike/7.5.19/lib/modules/Parser.pmod/_parser.pmod): Bad number of identifiers in inherit: 2 != 3 I don't quite know what to do with. Things appear to work nevertheless but what is it a symptom of? Parser.pmod seems to do some interesting three-level inheritance, due to the weird one-pmod-per-.so-file scheme which might be a clue, I suppose. Is that setup (a .pmod that just inherits some ____parser or similar) somehow superior to the old style setup where .so files could be modules right away?

Starting new pike processes from the testsuite
by Niels M�ller (ny flexiblare br�stkorg) ＠ Pike (-) developers forum 24 Feb '04

24 Feb '04

What's the recommended way of starting separate processes (which are Pike programs) from the testsuite? I want to make a test case for the SSL code, by starting a https process using the SSL.pmod/https.pike program (which I'm not sure it really belongs in the module tree) or some similar code, and then use the client code in the url/http modules to connect to it.

Embedding Pike into C/C++ game
by Marcus Comstedt (ACROSS) (Hail Ilpalazzo!) ＠ Pike (-) developers forum 24 Feb '04

Another restriction would be no multiplicity, i.e. only one pike interpreter per process. / Marcus Comstedt (ACROSS) (Hail Ilpalazzo!)
