has anyone had success with using libm in windows? I have legOS programs written from a solaris machine that compile fine and work when downloaded to the RCX, but I have not been able to compile them on a windows machine due to linking problems. The (...) (23 years ago, 24-Jan-02, to lugnet.robotics.rcx.legos)

(...) In the post you replied to saying "static doesn't matter", the proposal was: private: static int runWrapper(...) ; I then replied to your post, etc. Anyway, let's not degenerate into he-said-she-said.

(...) In fact, neither of these suggestions will work with the code as it stands, because the runWrapper() function tries to call the Run() function, which is a non-static member function. You could pass a pointer to the class instance (this) in the (...) (23 years ago, 21-Jan-02, to lugnet.robotics.rcx.legos)

(...) Unless you define a function as a member function, there is no this parameter at all. In the example given, it was not a member function at all (nor should it be). I believe you are thinking of a static member function vs. a non-static member (...) (23 years ago, 21-Jan-02, to lugnet.robotics.rcx.legos)

If you decide to use LegOS you won't be needing nor will you have the chance to use NQC because a RCX with LegOS loaded won't understand nor respond to any standard firmware commands. Check (if you didn't already) the side links at: (URL) From: (...) (23 years ago, 21-Jan-02, to lugnet.robotics.rcx.legos)

LegOS is an operation system ( a firmware replacement in itself) It's like a mini UNIX system, that will run true C compiled programs on RCX. NQC on the other hand, all it does is translate a NQC program into LEGO pCode that will be *interpreted* by (...) (23 years ago, 21-Jan-02, to lugnet.robotics.rcx.legos)

Hi everybody, I'm starting to use Lego products and I'm having problems to undrestand a few things. For example, I want to use NQC and I don't understand why the LegOS needs a C cross-compiler... or by having LegOS I don't need NQC? -- Paula Berger (...)

(...) Static DOES matter; it declares the method as being a "class" method, rather than a normal instance method. I believe there is no implicit 'this' parameter and therefore it can be treated like a normal function. Of course, it can't be linked (...) (23 years ago, 21-Jan-02, to lugnet.robotics.rcx.legos)

(...) No, static doesn't matter but it is possible the calling conventions of C and C++ might be different (I don't know of a platform where that is the case for a an extern function), so you might need to specify C linkage, as in: extern "C" int (...)
