gnat and fedora these days ?

[Reinert Korsnes]

Hi,

anybody tried "gnatmake" under an up to date (28 June 2005)
Fedora Core 3 ?

I have problems.  Example:

----------------------------------------------------------------------------
gnatmake -ffast-math -O -mcpu=i686 test1
gcc -c -ffast-math -O -mcpu=i686 test1.adb

Yes, and it works.

(To be honest, my system is *almost* up-to-date. I just now updated 
selinux-policy-targeted to version 1.17.30-3.13, but then I could hardly 
run anything at all because dynamic libraries couldn't be loaded, so I 
quickly reverted to 1.17.30-3.9. That's obviously not the same problem 
as yours.)

Have you tried it with GCC 4?

I don't do Linux, but perhaps you can increase your stack size? Often
a new version of a compiler will use a different amount of stack.

Under kernel-2.6.11-1.27_FC3 and previous it *did work* for me also.
The problem started yesterday after I did an "up2date".
If I start with the previous kernel, then I again can use Ada on Fedora. 
So the problem seems to be associated with the very very
last updates....

I tried the same thing last night, with similar results.

Among other things, Fedora Core 3 kernel 2.6.11-1.35_FC3 breaks
gcc (GCC) 3.4.3 20050227 (Red Hat 3.4.3-22.fc3), which I use to
compile Ada programs, and the APLX 1.1 APL interpreter.

They seem to work OK with kernel 2.6.11-1.27_FC3.

I recommend keeping an older kernel version that is known to be good
whenever upgrading to a new kernel, as this sort of thing happens from
time to time.

Oh, the kernel! I forgot that I haven't rebooted after the latest kernel 
update. 2.6.11-1.27_FC3 is still running. Sorry.

Under Linux 2.6.11-1.35_FC3 I get the same error as Reinert when I run 
Gnatmake on a tiny test program – Storage_Error at a-textio.ads:53:9.

This is line 53 of a-textio.ads:
    type File_Mode is (In_File, Out_File, Append_File);

Maybe it's all that non-executable stack / stack randomisation stuff that
I hear redhat use in their kernel?
