Since Fedora does not enable OSS output support at all, but still uses
padsp, and in Gentoo we could also make use of padsp without OSS output
support, split the two things in two parameters, although they both check
for sys/soundcard.h once.
On non-GNU, non-Sun linkers, the -z option is often not understood; make
sure that the -z nodelete option is usable before making use of it.
Unbreaks build on Mac OS X.
Instead of trying to re-execute pulseaudio itself with LD_BIND_NOW set,
just find the correct flag for the linker to request immediate bindings
(all ELF files support that option), and use that when linking the daemon.
Reduce the amount of compiled and executed code as well.
On FreeBSD the backtrace() function as well as the execinfo.h headers are
provided by libexecinfo (an optional package). PulseAudio “automagically”
identifies execinfo.h and proceeds to use it, but then will fail to link
against the library.
Thanks to Alexis Ballier for reporting.
The error message was way too generic, as it was very possible that libltdl
_is_ in the system but is not found because too old. Disambiguate this by
explicitly stating that the version 2 of the library is not found.
When we're unconditionally looking for a function, or an header file,
without particular libraries set, or with found/not-found conditional code,
we can save ~1K lines in the final configure script by using the _ONCE
variant.
This makes sure that for each header of function, the check is done exactly
once and never more, reducing the amount of code that has to be generated
and executed.
Instead of checking for GNU ld presence, check if the linker knows about
the -version-script flag. Non-GNU linkers may export the same interface.
It also allows to check for alternative syntax for symbol versioning.
Hi All,
This patch fixes the solaris audio device source and sink, and fixes some
portability issues that break the build on solaris. Questions and comments
welcomed.
I've tested this patch only with OpenSolaris Express snv 103. Eventually I
hope to be able to test a few older releases and older hardware (though it
is hard to say whether there is much interest in those).
This is my first brush with pulseaudio and so I read the wiki docs and
some of the source code but I'm still unsure of a few things. In
particular I'm wondering about rewind processing, corking and what (if
anything) the module needs for those. I'm also unclear on the implications
of thread_info.buffer_size, .fragment_size and .max_request, and whether
my code is correct or not.
This patch disables link map/library versioning unless ld is GNU ld.
Another approach for solaris would be to use that linker's -M option, but
I couldn't make that work (due to undefined mainloop, browse and simple
symbols when linking pacat. I can post the errors if anyone is intested.)
Thanks,
Finn Thain
The portability warning class warns during automake calls about non-POSIX
variable names and GNU make extensions. Since both happens with the current
Makefile.am files and it's reasonable to expect that they wouldn't be
rewritten (GNU make is a reasonable requirement), just avoid the warnings.
