• Kagamin (1/1) Feb 28 2021 mangleof should give _D4file6addOneFiZi, not _D6patron6addOneFiZi

------------------------------------------------------------------
module file;
extern(D) export
{
     int addOne(int i) { return (i + 1); }
}
------------------------------------------------------------------
module patron;
import file;	
void main()
{
     import std.stdio;
     int n = 1;
     writeln("mangled name of addOne is ", addOne.mangleof);
     numb = addOne(numb);
}
------------------------------------------------------------------
ldc2 -m64 -c file.d
ldc2 -m64 -c patron.d

ldc2 -m64 -shared file.obj -ofloadTime.dll
    Creating library loadTime.lib and object loadTime.exp

Both dumpbin /exports loadTime.lib and dumpbin /exports 
loadTime.dll
shows:  _D4file6addOneFiZi				
				
ldc2 patron.obj loadTime.lib

patron.exe
mangled name of addOne is _D6patron6addOneFiZi

// and library function is never called. Does not abend though???

-------------------------------------------------------------------

So the library function is named _D4file6addOneFiZi while the 
user wants to call _D6patron6addOneFiZi

So which name is "correct" and how do I get them to agree with 
each other?

fixing
    int numb = 1;

and your example work correct

ldc 1.24 / win10

P.S.I'm not recommend using such keywords as 'file', may cross 
with other modules.

I double checked my posting and of course works it now works!?!?  
I've been having trouble where it works and then it doesn't. I've 
been using examples with file.d, file1.d, file2.d, etc.  I also 
came across the note that Windows file system is not case 
sensitive. Or is that case in-sensitive?

This worked fine for Linux (Ubuntu) so you might be on to 
something.

Win10. Just try delete all obj, dll, lib and do full recompile 
from scratch.

module patron;
import file;	
void main()
{
     import std.stdio;
     int numb = 1;
     writeln("mangled name of addOne is ", addOne.mangleof);
     numb = addOne(numb);
     writeln(numb);
}
