Re: [Bug-xorriso] [PATCH] acinclude: fix LIBBURN_ASSERT_VERS_LIBS for out-of-tree builds

Hi,

Thank you for your patch.
Now i only need to understand the problem.

LIBBURN_ASSERT_VERS_LIBS tests for linker support of option --version-script.
If this test succeeds the option is added to LIBLDFLAGS, if it fails for
some reason, then the ./configure script reports
  disabled strict symbol encapsulation (test failed)
The negative effect would be that internally global symbols of libburn
get visible to applications which link libburn.so.
So it could lure application developers into using such symbols which
are not intended for public use.

Is this what you experienced ?
Do you agree with my assessment of the consequences ?

If so, then libisofs and libisoburn will need similar changes.

-------------------------------------------------------------------------

I will test your patch with my normal build situation.

Can you give me instructions how to achieve your situation ?
I have to confess that my autotools knowledge is strictly heuristic.


Have a nice day :)
