Details:
- When building with CMake, pkg-config files flac.pc and flac++.pc
are not updated with Version information. This causes a failure
when running a configure script in opus-tools
(https://github.com/xiph/opus-tools).
Note that OGG_PACKAGE is set to "ogg" exactly as in the configure.ac,
but it is only set when the building explicitly with libogg.
This commit contains the following changes:
- Drops -fstack-protector in favor of -fstack-protector-strong.
Consequently, the ssp-buffer-size parameter has been removed as
-fstack-protector-strong ignores array size.
- Add new global opt-out for stack smash protection. This is enabled
by default for both autotools and CMake builds. Users can opt out
of stack smash protection by passing -DWITH_STACK_PROTECTOR=OFF to
CMake or --disable-stack-smash-protection when running ./configure.
- Renames HAVE_SSP_FLAG to HAVE_STACK_PROTECTOR_FLAG in
CMakeLists.txt to be more readable.
- document version requirements in the top-level file.
- remove incorrect version requirements from sub-dirs.
- set min. required version to 3.5 in top-level file.
- set minimun required version to 3.9 under docs/ .
- make documents building an option (on by default.)
so, the tree can be built using cmake-3.5 using
-DBUILD_DOCS=0 on the command line.
The 1.3.3 release didn't update the version number in the cmake
build. It's too late to fix the release, but bringing the version
number into sync allows the metaflac test which verifies the
encoder's embedded version number to pass, giving us proper test
feedback on other changes to the development tree.
