Message-ID: Date: 18 Feb 91 00:23:37 GMT References: <1884@array.UUCP> Sender: news@Rational.COM Followup-To: comp.lang.ada Lines: 17 mark@array.UUCP (Mark Culp) writes: I believe you are trying to do this backwards. Pragma Interface allows Ada to call other languages. I do not believe the LRM specifies how OTHER languages are to call Ada--that would seem to be more the job of the linker for the other language than of Ada. Thus, in your example you have written the Ada Test_C_Interface to be able to call a C function called "C_Main_Routine". This should work (presuming you have tools sufficient to link the two languages). But then you try to call ada_routine from your C program. Does your C linker know how to do this? If not, this won't work. -- ***** DISCLAIMER: The opinions expressed herein are my own. Duh.
