Hello. I look and find that we start here:
http://hg.openjdk.java.net/jdk/jdk/file/b0fcf59be391/src/jdk.compiler/share/classes/com/sun/tools/javac/main/Main.java public Result compile(String[] argv, Context context) and this leads to: http://hg.openjdk.java.net/jdk/jdk/file/b0fcf59be391/src/jdk.compiler/share/classes/com/sun/tools/javac/main/JavaCompiler.java comp.compile(args.getFileObjects(), args.getClassNames(), null, List.nil()); Which leads to genCode: http://hg.openjdk.java.net/jdk/jdk/file/b0fcf59be391/src/jdk.compiler/share/classes/com/sun/tools/javac/main/JavaCompiler.java JavaFileObject genCode(Env<AttrContext> env, JCClassDecl cdef) throws IOException Which calls: return writer.writeClass(cdef.sym); And so I think if I've understood you (without a debugger running on this end) the JavaCompiler (in Java) will do a C compile on various C source code documents and share libraries and this will make the native binary "javac". Is that correct? The file "javac" is a native binary that is produced with a JavaCompiler called from the "bash configure && make all" command? Thanks! 😊 MR/ ________________________________ From: Erik Joelsson <erik.joels...@oracle.com> Sent: Friday, July 20, 2018 6:56 PM To: mr rupplin; build-dev@openjdk.java.net Subject: Re: Short Question - About javac.c where is it? Hello Max, Javac, like most of the command line tools in the JDK is written in Java, so to look at the actual program, I would recommend starting here (assuming current mainline at http://hg.openjdk.java.net/jdk/jdk): src/jdk.compiler/share/classes/com/sun/tools/javac/Main.java Most of the executables in the JDK are built from the same launcher src file with some different -D macro flags set to control which java class gets invoked by that launcher. The source for the launchers is located here: src/java.base/share/native/launcher/main.c Does that answer your question? /Erik On 2018-07-20 15:31, mr rupplin wrote: > In building the OpenJDK where may we find the source code file(s) for the > javac output? > > In libjli we find the java.c but locate javac.c returns no results.
