Any idea of this compile error--"language defined unit may not be recompile"? 

Thanks.

Since compiler messages are compiler-specific, it's always a good
idea to state which compiler and version you're using, the platform,
and to supply the complete specific error message.

It looks like the message might be from a GNAT Ada compiler,
and that for some reason you're attempting to recompile some
language-defined unit, such as Ada.Text_IO.

Re: compile error

Hi,

I'm using Gnat3.11p version on WinNT. The whole compile error display
is "language defined unit may not be recompile". It should not need to
recompile the language defined units when they are "with" by other
units. If the name of the unit is the same as that of the language
defined unit,will Gnat override the predefined one, or need to
activate some specific flags manually?

Cheers.

This is way old; get gnat 3.13p

Is this at the command line, or in some GUI? At the command line, the
gnat compiler is much more informative; for one thing, it tells you
what file it is compiling when it encounters the error.

The error message is saying that you cannot override language defined
units.

There is an option in gnat to let you do just that; consult the user
guide. But you should typically not be doing that.


Post the code you are trying to compile, so we know what you are
doing, then we can help more.
