Created attachment 344488 [details, diff] libpng-1.5.15.ebuild.diff Changes since the last public release (1.5.14): Enabled renaming of the extern (but not DLL exported) ARM filter functions. Also enabled inclusion of pngpriv.h in non-C files by preventing C/C++ specific definitions if PNG_VERSION_INFO_ONLY is defined. Added png_get_palette_max() function. Made a probably general fix for the preprocessing used to generate source files. This change might make the check for a special C preprocessor unnecessary, and it also eliminates the requirement for sed in the configure build process. Fix typo in Makefile.am, fix scripts/pnglibconf.mak and makefile.std Rebuilt Makefile.in, configure, etc., with autoconf-2.69 and automake-1.13 Fix 'setting' handling in options.awk and fixed palette_max API Remove SUN OS cc -E workround - no longer required Turn serial tests back on (recently turned off by autotools upgrade). Enclosed the new png_get_palette_max in #ifdef PNG_GET_PALETTE_MAX_SUPPORTED block, and revised pnglibconf.h and pnglibconf.h.prebuilt accordingly. Use approved/supported Android method to check for NEON, use Linux/POSIX 1003.1 API to check /proc/self/auxv avoiding buffer allocation and other library calls. Fixed a race condition in the creation of the build 'scripts' directory while building with a parallel make. Use parentheses more consistently in "#if defined(MACRO)" tests. Fixed PNG_ALIGN(ED)_MEMORY and add ability to turn off ARM_NEON runtime checks Updated the INSTALL document. Revised INSTALL to recommend using CPPFLAGS instead of INCLUDES. Revised scripts/makefile.freebsd to respect ZLIBLIB and ZLIBINC. Revised scripts/dfn.awk to work with the buggy MSYS awk that has trouble with CRLF line endings. Avoid a possible memory leak in contrib/gregbook/readpng.c Made the _SUPPORTED macro definitions consistent. The change made in libpng15 to #define *_SUPPORTED 1, to match the use of -D*_SUPPORTED (which means -D*_SUPPORTED=1) and avoid compiler warnings from GCC was made inconsistently and causes problems as a result, also some additions in pnglibconf.h.prebuilt were inconsistent (omitting the 1). This changes 1.5 back to the scheme used both before (1.4) and after (1.6). This might cause some build scripts to issue warnings, and might, in the extreme, cause some applications to fail (but they would fail anyway against 1.6). It seems safer to go for consistency, given the change in 1.6, not correctness here, particularly as 'make check' currently warns anyway on the symbols.dfn check because of the inconsistencies. Corrected Android builds and corrected libpng.vers with symbol prefixing This adds an API to set optimization options externally, providing an alternative and general solution for the non-portable run-time tests used by the ARM Neon code. It also makes those tests compile and link on Android. The order of settings vs options in pnglibconf.h is reversed to allow settings to depend on options and options can now set (or override) the defaults for settings. Fixed CMakelists.txt to allow building a single variant of the library (Claudio Bley): Introduced a PNG_LIB_TARGETS variable that lists all activated library targets. It is an error if this variable ends up empty, ie. you have to build at least one library variant. Made the *_COPY targets only depend on library targets actually being build. Use PNG_LIB_TARGETS to unify a code path. Changed the CREATE_SYMLINK macro to expect the full path to a file as the first argument. When symlinking the filename component of that path is determined and used as the link target. Use copy_if_different in the CREATE_SYMLINK macro. Eliminated two warnings from the Intel C compiler. The warnings are technically valid, although a reasonable treatment of division would show it to be incorrect.
