Hi Erik, I posted email as following: http://mail.openjdk.java.net/pipermail/core-libs-dev/2013-July/018790.html --- Hi,
I tried to build JDK8 with GCC4.8 on Fedora19. However, build process has been failed as following: ------ /usr/src/OpenJDK/tl/jdk/src/solaris/native/sun/nio/fs/UnixNativeDispatcher.c: In function ‘Java_sun_nio_fs_UnixNativeDispatcher_getgrnam0’: /usr/src/OpenJDK/tl/jdk/src/solaris/native/sun/nio/fs/UnixNativeDispatcher.c:1071:68: warning: unused parameter ‘this’ [-Wunused-parameter] Java_sun_nio_fs_UnixNativeDispatcher_getgrnam0(JNIEnv* env, jclass this, ^ gmake[1]: *** [libs-only] Error 2 make: *** [jdk-only] Error 2 ------ I guess this issue is caused by -Werror. So I've made a patch and it seems to work fine. Could you push this patch? Thanks, Yasumasa Suenaga --- I think that this is GCC spec. This option is described in manpage of gcc as following: --- -Wunused All the above -Wunused options combined. In order to get a warning about an unused function parameter, you must either specify -Wextra -Wunused (note that -Wall implies -Wunused), or separately specify -Wunused-parameter. --- Thanks, Yasumasa
