[Bug ada/29127] New: gnatchop-gcc: installation problem, executable not found

[schwab at suse dot de]

gnatchop breaks when invoked with a name that includes a hyphen, or if the
command is symlinked to such a name:

$ /usr/bin/gnatchop-4.1 support/checkfil.ada
gnatchop-gcc: installation problem, executable not found
no source files written
$ ls -l /usr/bin/gnatchop
lrwxrwxrwx 1 root root 12 2006-09-11 11:23 /usr/bin/gnatchop -> gnatchop-4.1
$ /usr/bin/gnatchop support/checkfil.ada
gnatchop-gcc: installation problem, executable not found
no source files written

This makes it impossible to run the ada testsuite on such an installation.

See comment #6 in PR 864, this is a known bug.

Hi Andreas, could you try this patch? If this works I'll submit it, if not
please let me know what's the next blocking point.

(sorry to be guessing, but I don't understand much of what this code is doing.)

Here is another try (probably breaks cross tools, but if it works at least we
know where the problem lies):

Doesn't change anything either.  I don't think this function is ever called
anyway.

It's not the same.  This is the problem that surfaces if you fix PR864.

I'm sorry, but I have an experimental patch (still needs some refining) fixing
PR864 which does also fix this PR, so I do not understand your comment, could
you
please elaborate ?

Most distributions have local patches that apply --program-suffix (and
similar configure switches) also to Ada executables (this is PR864).
If you do so and use for example '-4.3' as suffix you will hit
this (PR29127) PR because the Ada driver now thinks that binaries
with '-' contained are cross-compiling.  See also PR33857 for a
symptom of that.

It would be really nice if the Ada driver would finally cope with
being suffixed with the gcc version number.

Richard.

Right, as I said, this is exactly PR864 for which I have an experimental
patch which needs small refinements.
