MinGW-w64 gnatlink "undefined reference"

MinGW-w64 gnatlink "undefined reference"

[mjamesb]

Note: I know just enough to be dangerous here ... :-)

I guess I'm looking to open a bug somewhere and am trying to come up with all the details that they'll need.

I'm trying to do "hello world" in 64-bits on MS Windows, so this is:

  - 64-bit Win7, clean and up-to-date, and
  - Cygwin 2.738 installer to grab:
   - mingw64-i686-gcc-ada
   - mingw64-x86_64-gcc-ada

As you can see from the appended details, below, 32-bit is happy but 64-bit is not.

Do the details below cause anyone reading this to think "Oh, I know what that is!", or do I just dump this on someone and hope that they can fix it?

Thanks.

What this is saying is that the RTS (run time system) s-exctab.o
(System.Exception_Table) contains a reference which isn't satisfied.

This is nothing to do with your code, it's that Ada.Text_IO calls in
vast chunks of the RTS including exception handling.

To see what's happening at link time, you'd need to ask for verbose
linker output:

- for verbose output from gnatlink (which calls up the linker):
$ gnatmake helloworld.adb -largs -v

- for verbose output from the linker itself:
$ gnatmake helloworld.adb -largs -Wl,-v 


'__gnat_eh_personality_sj' is to do with the way the RTS handles
 exceptions. Reading between the lines in
 http://gcc.gnu.org/onlinedocs/gcc-4.5.0/gnat_ugn_unw/Exception-Handling-Control.html
 your problem will be related to the setjmp/longjmp method, and you
 could try 'gnatmake helloworld.adb --RTS=zcx', but in any
 case there's no excuse for the default RTS to be incomplete. I think
 you need to take this up with whoever built your compiler.
