Description Alan Matsuoka 2010-08-11 15:47:43 UTC 
Arch: x86_64

Problem Description:

The ADA system files that are part of the gcc-gnat package on a 64 bit system hard code word size (the size of an address or a pointer) as 64 bits. It does this even if you pass gnatmake the “-m32” flag.

How Reproducible:

Always

Steps to Reproduce:

Make and run the test program attached

Actual Results:

Opening the file
Writing the full integer
ADA.IO_EXCEPTIONS.DEVICE_ERROR
s-fileio.adb:1083
ADA_WRITE_TEST.FILE_WRITE_ERROR
ada_write_test.adb:58

Expected Results:

Opening the file
Writing the full integer
Closing the file
GOODBYE!

Additional Information:

The issue is fixed upstream with a package restructure. The adainclude and adalib contents have been put in a separate libgnat-devel package so that one may install libgnat-devel.i386 as well as libgnat-devel.x86_64 to get the desired files.

In RHEL5, gnat only supports the primary platform.  The amount of changes for multiarch ada support was huge and are really not backportable.
