| Near the end of texk/web2c/cpascal.h:

#ifdef getline #undef getline #endif #define getline web2c_getline Thanks. I'd change this request to "closed" if I could figure out how :+) ---------------------------------------------------------------------- Comment By: Taco Hoekwater (taco) Date: 2009-11-02 09:22 Message: Near the end of texk/web2c/cpascal.h: #ifdef getline #undef getline #endif #define getline web2c_getline ---------------------------------------------------------------------- Comment By: Bob Tennent (rdtennent) Date: 2009-11-02 09:08 Message: "there is a fix for this problem in texlive 2009" That won't help those of us using a distribution like Fedora 11 which is still at texlive-2007. Editing stdio.h isn't an option for most users. And editing the source of pdftex isn't straightforward because of the conversions. What exactly is the "fix" implemented in texlive 2009? ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2009-11-02 02:30 Message: POSIX 2008? That's new. It seems the glibc team likes to break old programs. http://blog.scottt.tw/2009/04/getline-is-in-posix-2008-and-exposed-in.html and numerous other hits. ---------------------------------------------------------------------- Comment By: Taco Hoekwater (taco) Date: 2009-11-02 02:13 Message: FWIW: there is a fix for this problem in texlive 2009. ---------------------------------------------------------------------- Comment By: Bob Tennent (rdtennent) Date: 2009-11-01 22:03 Message: This is the response at the Fedora bugzilla: getline is a standard POSIX 2008 function, and glibc headers by default offer POSIX 2008 namespace. See info libc 'Feature Test Macros' for details. You should just either fix pdftex to use a different name, not reserved by POSIX 2008, or use a namespace macro that doesn't provide POSIX 2008 stuff. https://bugzilla.redhat.com/show_bug.cgi?id=532230 ---------------------------------------------------------------------- Comment By: Bob Tennent (rdtennent) Date: 2009-10-31 12:50 Message: According to some reports on the web, the problem is in glibc-2.10.1. Apparently the non-standard definition of getline there should be "protected". Indeed, if I comment out that definition in /usr/include/stdio.h, pdftex builds normally. I'm willing to file a bug report in the Fedora bugzilla but I need some help: what exactly is the "protection" needed? ---------------------------------------------------------------------- You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=494&aid=4297&group_id=106
