报错信息处理
- src/hotspot/share/runtime/sharedRuntime.cpp报错
报错信息：
sharedRuntime.cpp:2875:85: error: expression does not compute the number of elements in this array; element type is 'double', not 'relocInfo' [-Werror,-Wsizeof-array-div]
解决方法：
编辑src/hotspot/share/runtime/sharedRuntime.cpp
# 修改前：
double locs_buf[20];
buffer.insts()->initialize_shared_locs((relocInfo*)locs_buf, sizeof(locs_buf) / sizeof(relocInfo));
# 修改后：
double locs_buf[20];
buffer.insts()->initialize_shared_locs((relocInfo*)locs_buf, (sizeof(locs_buf)) / (sizeof(relocInfo)));
- src/java/openjdk/src/java.desktop/macosx/native/libawt_lwawt/awt/CSystemColors.m报错
报错信息：
src/java/openjdk/src/java.desktop/macosx/native/libawt_lwawt/awt/CSystemColors.m:134:9: error: converting the result of '?:' with integer constants to a boolean always evaluates to 'true' [-Werror,-Wtautological-constant-compare]
解决方法：
编辑src/java.desktop/macosx/native/libawt_lwawt/awt/CSystemColors.m
# 修改前：
if (colorIndex < (useAppleColor) ? sun_lwawt_macosx_LWCToolkit_NUM_APPLE_COLORS : java_awt_SystemColor_NUM_COLORS) {
# 修改后：
if (colorIndex < (useAppleColor ? sun_lwawt_macosx_LWCToolkit_NUM_APPLE_COLORS : java_awt_SystemColor_NUM_COLORS)) {
- JavaVM Framework报错
原因：
Xcode 12.3 已经不再包含JavaVM框架
解决方法：
首先执行sh ./configure，然后修改下列文件
a) 编辑make/test/JtregNativeJdk.gmk
# 修改前：
BUILD_JDK_JTREG_LIBRARIES_LIBS_libTestMainKeyWindow := -framework JavaVM \
-framework Cocoa -framework JavaNativeFoundation
# 修改后：
BUILD_JDK_JTREG_LIBRARIES_LIBS_libTestMainKeyWindow := -framework Cocoa -framework JavaNativeFoundation
b) 编辑build/macosx-x86_64-server-release/spec.gmk
# 删除所有下列字符串
-F /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.1.sdk/System/Library/Frameworks/JavaVM.framework/Frameworks
c) 编辑./build/macosx-x86_64-server-release/buildjdk-spec.gmk
# 删除所有下列字符串
-F /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.1.sdk/System/Library/Frameworks/JavaVM.framework/Frameworks
重新编译
完成上述操作后重新执行make all
最后在build/macosx-x86_64-server-release/images/jdk可以找到编译好的jdk
