How am I supposed to compile the program? i.e. in general a multifile program having .hs and .cpps

I should work the way you did. I guess you have an error in your source code.

The oder method would be:

g++ -c main.cpp g++ -c querystring.cpp g++ -o out main.o querystring.o

Order is important. I think he'd have more luck with the last line changed to g++ -o out querystring.o main.o /M -- Magnus Therning (OpenPGP: 0xAB4DFBA4) magnus＠therning．org Jabber: magnus＠therning．org http://therning.org/magnus identi.ca|twitter: magthe

Is it? I must have slipped my mind...

Yes, in the link step it is, since it's single pass.

I usually use cmake or some other makefile, so I don't have to type these lines myself.

Same here, except for when I add support for some language to a build tool like cmake :-) /M -- Magnus Therning (OpenPGP: 0xAB4DFBA4) magnus＠therning．org Jabber: magnus＠therning．org http://therning.org/magnus identi.ca|twitter: magthe

Hi, I have three c++ files: main.cpp, and querystring.{h,cpp}

Guys, thanks for your suggestion, but the problem turned out to be inline constructor. I don't know why that doesn't work (it's as per ANSI though).

I'm sure actual examples would have helped here :-)

/M

So here it is: class QueryString { private: const string __qstr; public: QueryString() { throw Exception("Invalid constructor"); // defined in Exception.h } QueryString(const char* s) : __qstr(s) {} QueryString(const string& s): __qstr(s) {} http_map* parse(); }; PS: The default constructor is pretty dumb logic, I'll be changing that :) This doesn't compile on my box, saying `undefined reference to QueryString::QueryString()' or any other constructor. It doesn't matter if I define it inside (therefore implicitly inline as per ANSI) or outside using the inline keyword, it still won't compile (at least on my arch64). -- Regards, Nilesh Govindarajan Facebook: http://www.facebook.com/nilesh.gr Twitter: http://twitter.com/nileshgr Website: http://www.itech7.com VPS Hosting: http://www.itech7.com/a/vps

I'm absolutely stunned now when the same program (inlined constructors) compiles now, without ANY change in the gcc flags, etc.

Probably the CPU had got heated up that day lol.

The problem has come back again. Well anyways, let's close this thread, the problem is oscillating between success & failure. I'll google it out myself (if possible). Loading it dynamically (dlfcn.h) solves the issue for the time being. -- Regards, Nilesh Govindarajan Facebook: http://www.facebook.com/nilesh.gr Twitter: http://twitter.com/nileshgr Website: http://www.itech7.com VPS Hosting: http://www.itech7.com/a/vps

not that I mind solving a nit picky c++ puzzle and tracking down a code bug....but.. isn't this completely off base/topic for this list? -- @csgeek On Tue, Nov 16, 2010 at 11:08 AM, Magnus Therning wrote:

Paste a complete (all required files included), minimal example on gist.github.com or something, that might make it easier to spot the problem.
