Frequently asked questions about the GNU C++ compiler

FAQ for g++ and libg++, by Joe Buck (jbuck@synopsys.com)

This is a list of frequently asked questions (FAQ) for g++ users; thanks to all those who sent suggestions for improvements. Thanks to Marcus Speh for doing the index. A hypertext version is available on the World Wide Web at `http://www.cygnus.com/misc/g++FAQ_toc.html'.

Please send updates and corrections to the FAQ to jbuck@synopsys.com. Please do not use me as a resource to get your questions answered; that's what `gnu.g++.help' is for and I don't have the time to support the net's use of g++. If you ignore this request your message to me may be deleted without a reply. Sorry.

Many FAQs, including this one, are available on the archive site "rtfm.mit.edu"; see
`ftp://rtfm.mit.edu/pub/usenet/news.answers'. This FAQ may be found in the subdirectory g++-FAQ.

This FAQ is intended to supplement, not replace, Marshall Cline's excellent FAQ for the C++ language and for the newsgroup `comp.lang.c++'. Especially if g++ is the first C++ compiler you've ever used, the question "How do I do <X> with g++?" is probably really "How do I do <X> in C++?". You can find this FAQ at `ftp://rtfm.mit.edu/pub/usenet/comp.lang.c++', or in HTML form at `http://www.cerfnet.com/~mpcline/On-Line-C++-FAQs/'.
