error compiling gnat3.10p on a lynxos machine

error compiling gnat3.10p on a lynxos machine

[grave]

Hi all,

I've got the 2.7.0-lynxos-ppc version (from lynx ftp site) of gcc with
Ada capabilities.
Since I need an homogeneous environment with other machine (vxWorks
cards) I wanted to recompile gnat3.10p + gcc2.7.2 with it.

But when it try to compile the files types.ads, I've got the following
message :
types.ads:36:06: preelaborated unit dependency violation

Here is the types.ads code:

with Unchecked_Deallocation; -- here is the line 36

package Types is
pragma Preelaborate (Types);

other stuff here...

Can somebody explain me how to fix this problem ?
Can someone compile gnat1 without Ada compiling capabilities ?

Thanks in advance
