From: Carl Witthoft on 29 May 2006 20:04 HI -- I'm well experienced in programming under unix, but haven't ever played w/ c++. I have successfully compiled c programs on OSX (using gcc of course). The problem is my child needs to write stuff in c++ for a professor. Her first try crashed, which is to say gcc didn't like it. So: can anyone tell me what I need to set up? Should gcc be able to handle c++, or do I need to set some switches, or download different libraries, etc? Thanks for all advice, URL pointers, etc.

Well, I normally don't say it, but since you're someone experienced in programming on Unix, I think "RTFM" might be in order. "man gcc" is a great place to start. This kind of thing is the same on Mac OS X as on any other Unix box. GCC normally uses the filename extension to decide what language is likely to be in the file. File "foo.c" will normally be assumed to be C rather than C++, but "foo.cpp" would be assumed to be C++. There's also "g++", which is just gcc but with the default language set to C++ rather than C. Replace "gcc" with "g++" and you may be set. Finally of course there's gcc's "-x" option, which allows you to specify any supported language you like regardless of anything else. Name your C++ file "foo.java" if you like, and the right "-x" flag will make it work. -- Tom "Tom" Harrington Macaroni, Automated System Maintenance for Mac OS X.

Replace "gcc" with "g++" and you may be set. But note that if you compile and link in separate steps (as you would likely do if using make), then the link step should be performed with g++ in order to get the right libraries. Just depending on the suffix is not going to help you here. It's better to use g++ throughout when compiling and linking C++ code. > Finally of course there's gcc's "-x" option, which allows you to specify > any supported language you like regardless of anything else.

Try using g++ or manually setting the language to c++. I made this mistake too in the beginning. |
