gnatlink error on Debian Woody

gnatlink error on Debian Woody

[Frank Piron]

Hi,
if i try to link my ocitest.adb with
oracle's oci shared library on a debian
system, i get:

> gnatmake -L$ORACLE_HOME/lib ocitest.adb -largs -lclntsh
ld: cannot find -laddr2line
gnatlink: cannot call /usr/bin/gnatgcc
gnatmake: *** link failed.

On windows (with -loci of course) all works fine.
Is it a debian issue?

Are you sure about "ld: cannot find -laddr2line" ?
Maybe it is a "ld: cannot find -lclntsh"

Looks like you are trying to link with libaddr2line.a library.

I guess you have a -laddr2line in the command line or

pragma Linker_Options("-laddr2line");

in the ocitest.adb.

No, it is as i stated, literally (copied from terminal).
And libclntsh.so is located in $ORACLE_HOME/lib.

It looks so, but i didn't. At least i didn't consciously.

I checked already for this. Further i should mention, that i
have already successfully linked with the same command on a
Suse 7.2 Linux distribution.
Thanks for comments.

Finally i detected the cause of the problem.
I used - like you - the gnat.traceback.symbolic package.
This package contains the linker pragma "-laddr2line" in
file g-trasym.adb of the Debian - Gnat distribution.

Will it work if you remove the    

   pragma Linker_Options ("-laddr2line");

or will gnat.traceback.symbolic break?

It will break.

Unfortunately, symbolic tracebacks are a recurring issue with GNAT.
The binary distribution from ACT contains a libaddr2line built from an
old version of GNU binutils.  Very few GNU/Linux distributions, if
any, include libaddr2line.  This is actually not a problem with GNAT
itself but with recent versions of binutils.  I've tried GNAT for
several distributions and never found one that did support symbolic
tracabacks.  I myself had to give up on the issue when packaging GNAT
3.15p for Debian.

It is an annoyance to not have symbolic tracebacks, but not a major
loss of functionality.  You can always run addr2line manually on
non-symbolic tracebacks or run your program under GDB to achieve the
same effect.  Besides, proper Ada programs do not raise exceptions
anyway, do they? :)

As I said earlier, if the OP links their program with libaddr2line,
they must then distribute it with the resulting executable.  If the
program is non-free, this might be a problem because the GNU binutils
are under GPL, not LGPL.

Is clntsh a shared library?  If so, could you run ldd on it and report
the results?  Perhaps it is linked against libaddr2line, which is not
part of Debian because it came from a very old binutils.

If libclntsh.so is indeed linked against libaddr2line, you need to
either relink libclntsh.so without libaddr2line, or use the binary
gnat distribution from ACT; it does include libaddr2line.  Then, of
course, you resulting executable will require libaddr2line and you
will need to consider any distribution issues that may arise.

Which version of Gnat are you using? Are you using the Gnat 3.15p from:
http://www.ada-france.org/debian
?

   deb http://www.ada-france.org/debian ada main
   deb-src http://www.ada-france.org/debian ada main

Are you experiencing the add2line when compiling other programs?

Thanks, i will give this a try.

No. But didn't try to link with other .so's till now.

I tried gnat-3.15p and got the same error. Reason: there is
a linker pragma "-laddr2line" in the gnat.traceback.symbolic
package which i used successfully on win32. You have to build
the libaddr2line from the gnu binary utils. I found instructions
how to do it here:

An alternative is to use plain gnat.exception_traces ..
