It seems that the default configuration of GMP, with WANT_TMP_ALLOCA, allocates arbitrarily large temporaries on the stack. For example mpn_tdiv_qr allocates temporary storage proportional to the size of the input. Fredrik Hübinette (Pike author) reports that his pike program that calculates a million decimals of Pi crashes in gmp with a default configuration of gmp-4.1.2, but works fine if gmp is reconfigured with --enable-alloca=malloc-reentrant. The problem is made worse by linux threads (… [View More]

Strange GMP coredumps

I've figured out why Pike dumps core when using very large numbers in GMP. See this link for more info: http://fredrik.hubbe.net/hacker/viewtopic.php?t=26

The errors in this build, http://pike.ida.liu.se/generated/pikefarm/7.5/1446_351/compilelog.txt >> ...global.h:87:21: machine.h: No such file or directory is that a common error? Any clues? machine.h *is* in the build root where it should be.

xenofarm proxy
by Martin Baehr 16 Nov '03

16 Nov '03

hi, i just tried running xenofarm on one of my machines in vienna, then i noticed that there is a problem because i am behind a http proxy. setting $http_proxy does not seem to be enough, and grepping through the source i could not find any reference to proxy support either. what does it take to get xenofarm to run behind a http proxy? greetings, martin.

> The core modules are either built with a pike glue file, or if one > isn't provided, a two line glue file is automatically generated. /.../ Sorry, but that's not correct. You must be looking at a pike built with static modules. They get a glue file to appear in the right spot in the namespace, but dynamic ones don't need that. > True, and something that I shouldn't have let slip.

But that doesn't apply to third party modules. / Martin Stjernholm, Roxen IS Previous text: >2003-11-10 23:52: >Subject: Re: pike external module documentation >-------------------------------------------------------------------- >Thanks for the feedback...
