on i386-darwin, the file doesn't compile (I saved the file as "mini"):

ld: warning in mini, file is not of required architecture Undefined symbols: "_main", referenced from: start in crt1.10.5.o ld: symbol(s) not found collect2: ld returned 1 exit status

Are you sure you copy the right source code? Here is the result on Mac OS X intel 10.5: $ gcc -Wall test.c -o test epicalyx:c jjgod$ ./test sysname: Darwin nodename: epicalyx.local release: 9.2.2 version: Darwin Kernel Version 9.2.2: Tue Mar 4 21:17:34 PST 2008; root:xnu-1228.4.31~1/RELEASE_I386 machine: i386

Hi,

You're going to love that: on Solaris compilation works fine, but execution prints "uname() failed". And indeed, the section 2 man page for uname explains:

I am aware of that because there is some solaris users encountered the same failure here. It seems that we should use umask() function first. I had nudged Taco about that problem and provided a possible solution just ago. Yue Wang

No; instead of (uname(&uts)) it should be (uname(&uts) < 0) .

Well, no: if the function fails on Linux and returns, say, 1, this test wouldn't catch it. But Taco knows what to do, and the discussion is getting even more off-topic :-) Arthur

And SUS3 has this: Upon successful completion, a non-negative value shall be returned. Otherwise, -1 shall be returned and errno set to indicate the error.

Ah, OK. Arthur

I think it is better to only return a table while calling the Lua function. The table contains key=value pairs for {sysname=,nodename=,release=, version=,machine=}. For Windows, you just fill these names by hand instead(easy, isn't it?).

Easy to say, sure. You are not on windows either, I assume? Anyway, 0.30.0 will have both the old and the new ( os.uname() function), and the old variables will not go away until 0.40.0.

LuaTeX is going public in months, so before that every major API change is OK to the developers. After public, changing APIs will make other developers unhappy.

I do not know what you are referring to. Nothing in the API is fixed until 1.0.0, and that is still a few years off ! Best wishes, Taco

No, It wont. In Linux/FreeBSD/Mac OS X, -1 will return if it failed. I am pretty sure about that because I read the manual pages of these operating systems yesterday.

i suggest to direct mails about this topic to taco directly Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
