building native libraries outside ndk

[guich]

Hi,

I'm just starting to create my native lib, so, please excuse me if i'm
asking a too dumb question.

I have this directory scheme:

/TotalCrossSDK/src (java files)
/TotalCrossVM/src (native C files)

From what i read, it is not possible to build a native library outside
the NDK. Actually, i placed my Android project inside a TotalCrossVM/
builders folder, but when i run "make APP=tcvm", i get that the
makefile was not found.

Can i run the make with a project outside the NDK folder? Or do i have
really to put my project under the NDK?

Merry Christmas.

sure you can
but first you need to create a folder inside $NDK/apps/your_proj
in the your_proc folder create an Application.apk
specify the
APP_PROJECT_PATH to the absolute path

So, the creation of a "project stub" in $NDK/apps/your_proj is really
mandatory? Couldn't i call "make APP=xxx ndk_folder=yyyy" so i could
run make from inside the absolute path?

I'm asking this because we work in a team with CVS and i really don't
want to add NDK to the CVS.

thanks

Just create a symlink from $NDK/apps/<name>/Application.mk to your $PROJECT/Application.mk

Thanks, but symlink is only available in ntfs on windows, and i use
fat32. I really hope that this can be better supported in the future,
maybe passing a parameter to make.

thanks

This will be supported in the future, but I can't give specifics or an ETA right now.

hi guich
but back to your question
adding ndk to cvs is not correct way to use cvs ,right?

also i think your suggestion should be that

YOUR_PROJ$> make -f $(NDKPATH)/GNUmakefile APP_FOLDER=/path/to/
YOUR_PROJ

because i think the way you say is to write another makefile or script
to invoke the Makefile in NDK, and not to improving current status of
NDK

thanks

As others have pointed out, you can't. This is my workaround, as part
of my out-of-tree Makefile:

----
.PHONY: build
build: ndksetup
cd $(NDK_ROOT) && make APP=appname

.PHONY: ndksetup
ndksetup: $(NDK_ROOT)/apps/appname/Application.mk

$(NDK_ROOT)/apps/appname/Application.mk: ndk-apps/appname/Application.mk
cp -R ndk-apps/* $(NDK_ROOT)/apps/
----

Create ndk-apps/appname/Application.mk in your project directory. Then
as long as your Makefile user has installed the NDK and set NDK_ROOT
correctly, the Makefile will copy across the application stub if it
doesn't exist / whenever it changes.
