Hi all,

I'm having trouble compiling a C++ project,which was originally written using the VC++, in Dev-C++. The problem is identifying the compiler errors that are incurred by the Min-Gw compiler(the default compiler that is shipped with Dev-C++)
I've currently have converted the project(which is an opensource example of JNI) to the Dev-C++ project standard using the Dev-C++ IDE. But now when I try to compile it gives me 11 compiler errors. The 1st of of them is :
But the above variable '_resource' has already been declared in the header file : "jni_resource_base.h" and that file has been included in the file : "jni_resource.h".
I guess this will be clear if you could open the project I've attached here as a zip file(as a Dev-C++ 4.9.9.2 project) and try compiling. I've been trying for weeks but still couldn't get anywhere to solving this issue. Therefore It would be great if anyone of you could help me in this.



Thanks & Regards,
Shehan.

Is there a valid reason why you are using Dev C++ when you can nab a free version of VSC++?

shen747

Yes actually I do. I need to make this jni related code as much platform independent as possible.So as Min-Gw is the at least the a bit equivalent of the GCC for windows,i actually no other choice but to use Dev-C++.

platform independence has to do with your code, not the IDE/compiler you write it on.

Please if you can't help me with the problem.Don't post any more unnecessary comments. Period.
It will help save both parties a lot of time. Why I need to compile in Dev-C++ is my business. And if you can help me with the problem then please do. Without trying to hide your ineptitude with sarcastic and wannbe geekish comments. I'll not reply to anymore studpid comments by any of you unless it's related to the solution. thanks !!..

It seems your problem is Why am I getting errors when my template-derived-class uses a member it inherits from its template-base-class?

Edit: oops, it was the next one.

I've never used JNI, but I can tell you the MinGW that comes with Dev-C++ is outdated. Dev-C++ is dead, and hasn't been developed for years. That could be why you received those replies. We mostly suggest Code::Blocks as a replacement (cross-platform) or Visual Studio Express. If your project is originally a VC6 project, it likely contains windows specific code, and probably won't compile cross-platform. You're better off having VS convert it for you. When you're ready you can easily use a different IDE/compiler for cross-platform compatibility. Infact my projects have project files for both Code::Blocks and Visual Studio. You can also use make, cmake, etc. for cross-platform goodness and ditch the integrated IDE/compiler. It really depends on your source code. Use VS imo.

Oh, and ignore my comment all you want.

Well, i was actually trying to help you until you made that asinine comment. Go 'help' yourself.

If you chose VC++, then it might well turn out that the code is "correct" again (it seems to be more permissive with templates than the standard allows - may-be one can make it more strict in newer versions?). Using GCC to achieve better standard compliance seems like a right step. DevCpp is indeed rather outdated, and you can set up Code::Blocks with a number of compilers (I think it even comes with MiinGW by default).

You are right. Code::Blocks comes with exactly the same compiler, just a newer version. On top of that, it's the best free IDE for C/C++ programming, hands down, in my opinion.

There's still nothing that beats Visual Studio and it's insanely useful visual debugger, however. But to each his own.

I've seen so many people recommending Dev-C++ to people that I'm reaching the point where I want to push for a "shoot-on-sight" for everyone who does so - it's outdated, useless crap. It might not be so outdated that it makes much of a difference right now(Only like 4 years old or so), but it might just become the next generation's "Turbo-C++" annoyance. Especially with C++0x coming up relatively soon and all that.

[/rant]

Either way, to each his own.

Wow thanks anon for pointing me to Code::Blocks. It solved my issue. Thanks everyone ;-). And also thanks Dae for mentioning Boost in your signature. It allowed me to take my C/C++ to the next level.
