Question

我已经从我简单的Dagger-2代码中成功生成了Objc .m和.h文件。

https://gist.github.com/OscarRyz/ffd976fcae9acf87dbe1

现在我正在尝试使用j2objcc编译这些文件，但错误消息显示它找不到.h用于Dagger-2类：

j2objcc  -c  -I. `find app -name *.m`
In file included from app/DaggerSearchComponent.m:10:
./app/SearchInPage_Factory.h:10:10: fatal error: 'dagger/internal/Factory.h' file not found

问题：这是否意味着我需要在生成ObjC代码时拥有库源代码，以便为这些代码生成.h？

Dagger并没有与j2objc一起发布，所以你必须自己构建它。为此（需要Maven，在Building J2ObjC wiki中描述）：

git clone https://github.com/google/dagger.git
cd dagger
mvn install
j2objc -d build -classpath $J2OBJC_HOME/lib/javax-inject.jar -sourcepath core/src/main/java `find core/src/main/java -name *.java`
cd build
j2objcc -c -I. `find dagger -name *.m`
ar -r libdagger.a *.o

注意：指定J2OBJC_HOME，或者解压缩j2objc发行版，或者构建j2objc，即dist目录。要测试，＆＃34; ls $ J2OBJC_HOME / j2objc＆＃34;应列出j2objc脚本。

这些指令生成macosx架构，在测试时非常有用。需要为要使用的每个体系结构重新编译文件 - 最简单的方法是在Xcode中创建一个静态库项目，添加已翻译的文件，然后在您的应用程序中包含此项目并将其添加为依赖项你的应用。

ar会警告＆＃34; libdagger.a（package-info.o）没有符号＆＃34;，可以忽略它，因为它没有任何符号。
