I have written a glut-application and compiled it on Mac OS X NOT using = the project development tools but the g++ compiler. Now, I decided to design the user interface using pui but even just = including the headerfile without actually using anything from the = library creates real problems because the (standard) g++-3.3 compiler = doesn't recognise the plib files as C++ and is therefore not able to = compile. I have seen on the mailing list that this problem has surfaced a number = of times but couldn't find a solution apart from the suggestion of not = using plib but compliling the code into my project. Does anyone who had = the problem know, how to deal with it? Or any other ideas? Thanks a lot, Bernhard |

If it isn't able to compile your application with the PLIB headers in them then the problem is not how it recognises PLIB's files - but rather a matter of what language it thinks the application is written in...header fines have to match the language of the file they are included into. My guess is that your application is in C and that's what the problem is.

Thanks for the immediate reply.

It is completely right that the compiler doesn't recognise the language
of pu.h. The problem is that the application IS indeed written in C++
and has been compiled using g++-3.3 without any problems as long as I
don't include the header pu.h.

Sure, here it is (though only the first few lines because the problem
becomes evident and the whole takes up about ten pages...

Perhaps you included plib headers inside a " extern "C" " clause, like=20
this :
extern "C" {
#include "plib/ul.h"
#include "plib/sg.h"
}

Unfortunately that doesn't work either.
These headers are written using C++. For some (unknown) reason, the=20
compiler thinks that they are written in C, then tries to read them as=20=
C and finally complains because he cannot understand them.

I was not trying to tell you what to do, but warn you about a possible
pitfall. You *shouldn't* have this header in an extern "C" clause
because they
are C++. Perhaps you included them in another header that is in such a
clause

Sorry, I should read properly...
But no that isn't what is happening,

But think about this - the header file is being '#include'd into the source for your application. The compiler doesn't "recognise the language of pu.h" - it takes the ASCII characters inside that file and inserts them at that point into your application file. Then the resulting ASCII stream is compiled using whatever language the application is written in. The compiler doesn't *see* included files as things to be compiled in their own right. So - it seems that your application is being compiled as C code - and not C++. Perhaps your application code is sufficiently C-like that it's being successfully compiled as C - until you include some header files that are more certainly in C++. Why that should be, I'm not sure. > g++ -g -I/usr/include/gcc/darwin/3.3/c++ -c MePSim.C The '.C' extension (capital C) certainly indicates to the compiler that the code should be C++ - is it possible that something on the Mac is forcing the filename into lowercase before passing it to the compiler??!? Try renaming the source file to .cc or .cxx Another slightly odd thing is that the first error the compiler notices is: > /usr/include/plib/ul.h: In function `void ulEndianSwap(short unsigned int*)': > /usr/include/plib/ul.h:336: error: declaration of C function `void > ulEndianSwap(short unsigned int*)' conflicts with > /usr/include/plib/ul.h:327: error: previous declaration `void > ulEndianSwap(unsigned int*)' here ...well, there are a LOT of C++ language features earlier in ul.h that ought to have been flagged by the compiler if it thought it was compiling C. ---------------------------- Steve Baker ------------------------- HomeEmail: <sjb...@ai...> WorkEmail: <sj...@li...> HomePage : http://www.sjbaker.org Projects : http://plib.sf.net http://tuxaqfh.sf.net http://tuxkart.sf.net http://prettypoly.sf.net -----BEGIN GEEK CODE BLOCK----- GCS d-- s:+ a+ C++++$ UL+++$ P--- L++++$ E--- W+++ N o+ K? w--- !O M- V-- PS++ PE- Y-- PGP-- t+ 5 X R+++ tv b++ DI++ D G+ e++ h--(-) r+++ y++++ -----END GEEK CODE BLOCK----- |
