All,
On 2014-11-29 14:34 +0100, Yann E. MORIN spake thusly:
> Because shairport-sync uses AC_CHECK_LIB to find some of the needed
> libraries (opensl, alsa, popt...), it fails to bring in the dependencies
> of those libraries; for example, -lssl requires -lz.
>
> When doing a dynamically-linked build, those dependent libraries are
> pulled in thansk to the DT_NEEDED ELF tags, but those are not available
> in static libraries.
>
> Use PKG_CHECK_MODULES instead of AC_CHECK_LIB, and emulate the results
> of AC_CJECK_LIB (i.e. set the HAVE_LIBxxx and the LIBS variable
> appropriately) to minimise the amount of code touched.
>
> This should fix:

> Note: I was not able to rproduce the build failures: the popt check was
> sucessfull for me, but failed in the following checks for ssl and alsa.
> The fix to popt is just a generalisation of the fix to the other two
> libraries.

All three patches applied upstream:
https://github.com/mikebrady/shairport-sync/commit/2a430ec434674ed8c1959698c061662bb7abc1a1
https://github.com/mikebrady/shairport-sync/commit/e5a74a3ff08134a2b11f07bd850659d7816fb03d
https://github.com/mikebrady/shairport-sync/commit/1f759e57e8c0682613eaaf89a46fdf6db4c6b5cd
There is now a new release with those three patches, but that would make
us bump pass a few releases, from 2.1.8 to 2.1.13, with some new
features along the lines.
So, for the release, I suggest we just apply those three patches, and
I'll send a version bump after the release has been cut.
Is that OK?
Regards,
Yann E. MORIN.
