Has anyone gotten NASM to work with Borland c++ 5.01?
I've gotten NASM to generate .obj files, but when I link
the linker complains about defined symbols. (These are
symbols that I define in my assembler code)
Is there any documentation about how to use BC 5.01
with an assmbler?
Thanks,
Philip Knodle
 

Each symbol has a public name, the name that will be used by the linker. C
public names are the same as in the source code except that a leading
underscore has been added. C++ public names are formed differently. So if
you have this function prototype:
int MyFunc(int i);
The C public name would be _MyFunc but the C++ one might look something like
@MuFunc$qi
However if the function prototype in C++ code were this:
extern "C"
int MyFunc(int i);
Then the public name would be formed as if it were C langugage and might
match up with the public symbol from your assembly source file.
. Ed

the function name with a '_' prefix. When calling it from C, don't include
the '_'.
For example, you can declare a function in assembly like _MyFunc,
then call it from C, MyFunc(...).
2, If you really want to get an assembler work with BC++, TASM or LZASM
is a better choice.
