The following is the command output by dub with --vverbose switch. It generates a file which is 6094400 bytes in size

dmd -lib -of.dub/build/library-debug-linux.posix-x86_64-dmd_2077-7BB682AB55F152616E128DD715E887DF/libdjni.a -debug -g -w -version=Have_djni -Isource/ source/app.d source/jni/JavaArray.d source/jni/JavaClass.d source/jni/JavaEnv.d source/jni/JavaField.d source/jni/JavaMethod.d source/jni/JavaObject.d source/jni/JavaString.d source/jni/JavaVM.d source/jni/JniHelper.d source/jni/JniProxy.d source/jni/jni.d source/jni/package.d -vcolumns


The below command generates a library file of size 3586152 bytes.

dmd -oflibDJni.a -lib -H -Hdimport/jni source/jni/*.d

so the file generated by dub is almost twice in size. Why such a difference ? What does dub include in the generated file ?

The most likely culprit would be -g, which adds symbolic debug info.

dub build --vverbose

That is the command I used. Would it be right to assume that -g is being added because --vverbose ? The reason I ask is the file size is about the same when I run the below command.

It's because debug builds are the default. See:

You need to add "--build=release", otherwise dub will build debug by default.

TY Mike, that explains it.

Thanks Ivan.
