Muscle and DevC++

Just putting it in the lib folder isn't enough; are you actually telling the Dev-C++ linker to use the file?

Under the Project menu, select Project Options. Click the Parameters tab, and in the Linker textbox you have to enter your linker info... which in this case sounds like you should enter: -lmuscle

Hope this helps!

Yep, -lmuscle is already put in the linker parameters. It's a .dev file given in the muscle package, which had all necessary linker parameters set already, including -lmuscle, and at least 20 others.

Post some of the exact error messages and maybe I can garner a clue. My only haphazard guess is that something happened with the changed gcc version?

(<-- is dev-cpp freak who has compile MUSCLE before)

Cool, I'm glad to hear someone managed to compile it with devc++ :)

Ok here's a small selection of all the different errors, in the compile log. Most errors have to do with operator new, operator delete and dynamic cast.

There are also gxx_personality errors. I have got these before once, when using .o files compiled with an older version of gcc in a newer version of gcc. However now I've made sure that there are no such things and everything, both the libmuscle.a and the devmuscle.exe file, are compiled with the same compiler.

The first is not an error but I show the commands it gives to gcc.

There must be something terribly wrong with your code. Please fix it.

Note how many of the errors come from libmuscle.a, so that means that it has successfully found that file so I put it in the correct folder.

The above are the errors from DevC++ 4.9.9.0.

There's also another problem, a DevC++ 4.9.9.0 bug: sometimes when trying to open the libmuscle.dev project, the IDE crashes!! Only when trying to open it in a few different ways (from recent files, by clicking the project in windows explorer, or by using the open dialog), and opening a few other projects now and then, it finaly manages to open it.

I can't access the #bloodshed irc channel, because the undernet server allows only 2 connections per IP, and about 40000 students share my external IP.

Ok, well it looks like you're trying to compile C++ code with gcc... which won't work. You need to use g++.exe not gcc.exe.

That might solve all of your problems... but I also see that you don't have -lmingw32 in your linker string. As far as I know, all programs being compiled with mingw require that you link in the mingw32 library.

Hopes this helps!

Hi, indeed, all .cpp files didn't have the setting "compile as C++" enabled! So I enabled it, and also had to copy all "compiler" parameters to "c++ compiler parameters"

Everything is compiled with g++ now, and.... It still gives the same errors, again about new and delete :(

Now its all the time errors like:

" [Linker error] undefined reference to operator delete(void*)' "
" [Linker error] undefined reference to vtable for __cxxabiv1::__si_class_type_info' "
etc.... :(

woah... I've never been able to solve personality errors when I've encountered them. From my understanding they should only occur when your not linking against the C++ std libs though...

Maybe try and create a new c++ project and wrap the files, see if that works?

Ranger_One:

I did it, and was hoping quite hard that it'd work, but... I don't know if it's good or bad news, but it gives different errors:

I'm still extremely bad at understanding linker errors, so I'm lost again :(

I mean, I compile everything, it's all correct C++ code, and then the linker tries to put it together, and the linker doesn't find all stuff or something? Why?

It seems to be looking for:

-lws2_32
-lwinmm

also, it seems that it can't find some of it's own functions... don't know how to deal with that. Unless you missed one or more source files?
