Hello, it is currently not possible to build JDK9 on OS X El Capitan.
The problem is the line #include <Accelerate/Accelerate.h> in files jdk/src/java.desktop/macosx/native/libawt_lwawt/font/CGGlyphImages.m jdk/src/java.desktop/macosx/native/libawt_lwawt/awt/ImageSurfaceData.m On OS X El Capitan, the Accelerate.h file contains #ifndef __VECLIB__ #include <vecLib/vecLib.h> #endif where vecLib.h contains #error "The vecLib framework is deprecated. Please include <Accelerate/Accelerate.h> instead of <vecLib/vecLib.h> and link to the Accelerate framework instead of the vecLib framework." This is also the error with which the build fails. Adding #define __VECLIB__ to the two aforementioned files resolves the error, as it avoids that the Accelerate.h file loads the vecLib.h file. I have no idea of the impact of adding #define __VECLIB__ , and what it might break. The purpose of this email is more to ensure that other people who stumble against the same problem can find a solution using Google. Regards, Robin
