* [Bug libc/2486] New: <netinet/in.h> does not compile in C++. Patch with conventional fix available. @ 2006-03-24 23:52 dank at kegel dot com 2006-03-25 0:51 ` [Bug libc/2486] " dank at kegel dot com ` (2 more replies) 0 siblings, 3 replies; 4+ messages in thread From: dank at kegel dot com @ 2006-03-24 23:52 UTC (permalink / raw) To: glibc-bugs This is a classic, longstanding bug in all versions of glibc and many other C libraries. The essence is that struct ip_opts { ... char ip_opts[40]; ... is not legal C++. The traditional way of fixing this is to capitalize the first letter of the member when compiling for C++. A patch which does this, and applies to all versions of glibc is at http://www.pengutronix.de/software/ptxdist/patches-0.5.2/glibc-2.2.5/generic/glibc-2.2.5-ip_opts.patch There have been repeated requests to fix this over the years, but for some reason, nobody filed a glibc bug report before! Here are a few old posts about the problem in general, and how it's been fixed elsewhere: http://cvs.openbsd.org/cgi-bin/query-pr-wrapper?full=yes&numbers=681 http://gcc.gnu.org/ml/gcc/2002-05/msg00791.html http://www.cygwin.com/ml/ecos-patches/2002-06/msg00005.html http://www.netbsd.org/cgi-bin/query-pr-single.pl?number=19880 So, time to apply this patch in glibc head (and to the head of the 2.3 branch, if possible)? -- Summary: <netinet/in.h> does not compile in C++.

The gcc296 shipped by Fedora does not report this error. So perhaps this is only of interest to embedded system developers and/or those who use ancient compilers. I'm marking this bug WONTFIX for now; affected developers can apply the patch. -- What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution| |WONTFIX http://sourceware.org/bugzilla/show_bug.cgi?id=2486 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ^ permalink raw reply [flat|nested] 4+ messages in thread

Newer versions of gcc implement DR#80 for C++, which allows data fields to have the same name as the class if the class does not have a user-declared constructor. http://std.dkuug.dk/jtc1/sc22/wg21/docs/cwg_defects.html#80 -- http://sourceware.org/bugzilla/show_bug.cgi?id=2486 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ^ permalink raw reply [flat|nested] 4+ messages in thread
