the test you have reused and the one I just wrote are for two different things.
We have two things here:
- the first check tested for --hash-style=gnu option support.
ld supports it, result = yes
If you look at my change, I have removed this check. IMHO, it is
obsoleted by the AC_TRY_RUN one. ;-)
IMHO, it does not make sense to enable --hash-style=gnu if the
application can be linked and not started on the given system. So, the
AC_TRY_LINK is not needed because the same success/failure is detected
also by AC_TRY_RUN.
Okay, I understand the logic.
- the check I just wrote tested if binaries linked with the --hash-style=gnu
can be run
something in the system doesn't grok it, result = no
By integrating the two autoconf checks, we're back to a situation where
the build process happily links binaries with --hash-style=gnu and crashes
a few moments later trying to run them.
Are you sure? Have you looked at my changes? :-)
I admit I only have taken a cursory look to the patch itself. Howewer, I've
also updated my git repository and tried to build LibreOffice.
The build failed exactly as I described it above.
What I wanted to do is set a reasonable default of "gnu" or "sysv" for the
--with-hash-style option depending if the machine can run such binaries or
not.
I hope that I did the same.
config.log says HAVE_LD_HASH_STYLE='TRUE' and yet my system can not run the
newly generated makedepend.
The only difference might be that my
approach does not care only about the default. In addition, it does not
allow to force "gnu" on systems that are able to link but are not able
to run such programs. IMHO, it does not make much sense.
I preferred not to assume too much on this point and allow some foot shooting.
It would even
cause compilation problems because some helper tools need are compiled
and ran during build. Or did I miss anything?
Yeah, that's exactly why my builds are failing :-(
