Re: Problem compiling simple Ada program


Michael Swanson wrote:

I am trying to compile and link a simple Ada program on Cygwin. The code for this looks like:
Hello.adb:


with Text_IO;

Procedure Hello is
begin
    Text_IO.Put_Line("Hello");
end;

This compiles fine, but when I try to link the hello.o file, I get this error:
hello.o:hello.adb:(.text+0x18): undefined reference to '_ada__text_io__put_line__2'
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../libcygwin.a(libcmain.o):: undefined reference to '_WinMain@16'
collect2: ld returned 1 exit status


This looks like I don't have the right libraries for Ada, but I have installed the entire Devel and Lib group in Cygwin. Is there a simple solution to this? Thanks ahead of time for any help you can give me.

Works for me(tm).


$ gnatmake HelloAda
gcc -c HelloAda.adb
gnatbind -x HelloAda.ali
gnatlink HelloAda.ali

$ ./HelloAda
Hello


What are the commands you use?


Please post the outoput of `cygcheck -svr` *as attachment* to the list.
