Trouble with CW 10 linking Coldfire assy lang object file

[Ainslie]

I am trying to call an assy lang routine from C but the linker always shows undefined symbol. The file is being assembled, and I can create a list file. CW7 forced me to prefix the routine with an underscore, but that appears to make no difference here on CW 10.

Hello

In the assembly source file the function name should start with an underscore and be defined as global.

This is done as follows:

   .global _foo      .text_foo:   nop   nop   nop   rts

In ANSI C module you need a prototype for the function without underscore as follows:

void foo(void);

 This should work.
