Hello there.

First, I would say "thank you very much" to DJ Delorie for his superb
C/C++ compiler.

I am used to working with Borland Pascal libraries and I am beginning
C++, but i've got many problems in compiling libraries ...

First,  when i use RHIDE, i change "main target name" to LIBxxx.A
en then use COMPILE and LINK. The problem is that i often get an empty
file (around 8 bytes) ?!?, but not at each time.  Where is my error ?

Another day, i tried to insert ASM code into my library. I made the
next things :

     write code (i am not used with At&T syntax, but I made it!)
     compile to an OBJ file (OK)
                                        compile the rest of the library in an OBJ file (OK)
                                        link the obj with ar (binutils, no error)

And when i try to use this library, the compiler cannot find the
function ... ar says that LIBxxx.A contains all files.

I did so :

     in the header file :

     #define USI unsigned short int
     ...
     Pic2Buf(char * pic, char * buf, USI xp, USI yp, char zval);

     in the asm file :

     ...
     .globl Pic2Buf         (I even tried _Pic2Buf)
     ...


     Pic2Buf:       (here too : i tried _Pic2Buf)
                                                   pushl  eax ...

Perhaps you are thinking my question is stupid, but can anybody help
me ?

Thank you very much
                                             DASH
