With templates it's easiest to declare and implement in one file. The compiler likes this. Anything else you try requires extra work. Unless you're working in an embedded environment I don't see how executable size should even be a concern. --------------------------------------------------------- Aaron Wright

I'm trying to refrain from using that because it can bloat up the executable size... unless you can tell me otherwise. in general the program will be compiled using g++ for now, maybe I'll add support for windows compiler later. also, I'm trying to keep the definitions to the header files and the code to the src files.

I'm not sure where to follow from here... if I've did what they say and I still get a undefined error, then I must have miss configured cmake. when I add extern to the deceleration in the header, I get this error: storage class specified for `Array` On Tue 29 Dec 17:16 2009 Eric Noulard wrote: > 2009/12/29 e...@cs.bgu.ac.il <e...@cs.bgu.ac.il>: > > hello Eric, thanks for the response. > > I'd like to solve the Array issue first, then the boost because I have a feeling it is a different one because when I disable the relevant code it doesn't generates the error even when other parts of the program (such as the threadpool). > > here are the array files content: http://codepad.org/klDWMowB > > I assume the content of the .hpp is between #ifndef CARRAY_HPP > then the code is the .cpp file. > > The trouble comes from the fact that your class is a template one, > so that the content of the .cpp file may not be compiled independently > "as-is" because it must be instantiated first. > > I invite you to read this: > http://www.parashift.com/c++-faq-lite/templates.html#faq-35.12 > and may be this one too: > http://corfield.org/index.cfm/event/cplusplus.section/section/ptexp > > Note that the "export keyword" solution may not be a good one > because many compilers do not implement it, beginning with gcc: > http://gcc.gnu.org/bugs/#nonbugs_cxx > > > beside a strange typo that I've done, I don't thing I've miss configured it somehow. > > I think may be you did not played a lot with templated classes. > (just a guess I may be wrong). > > Concerning this issue, I'm pretty sure this is not a CMake one. > > -- > Erk > Membre de l'April - « promouvoir et défendre le logiciel libre » - > http://www.april.org > _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
