Realm-java: Add support for building Realm on Windows

[NizarETH]

Hi developers !

I had this error when I run the project of Realm from the officiel site :
Error:Execution failed for task ':downloadCore'.

A problem occurred starting process 'command 'make''

Hi @ivanove
Two things that come to mind:

1) Do you have make on your PATH
2) You firewall is blocking the download of the core database from here http://static.realm.io/downloads/core/realm-core-android-0.88.4.tar.gz

If it is neither, can you post the output of ./gradlew clean assemble --stacktrace?

[NizarETH]

Hi,

thank's for your quick response, by the way I disabled my fire-wall, I work
on windows 7 using android studio, for the command "make"
I don't found where I can add it.

I look for something near to my problem in stack overflow but there's
nothing.

I install this tool http://gnuwin32.sourceforge.net/packages/make.htm
and I add this link C:\Program Files (x86)\GnuWin32\bin to path and the
same problem.

Hi @ivanove
Have you tried installing cygwin (https://www.cygwin.com/) and trying through that?

[NizarETH]

Hi,

I'll try it, right now.

[emanuelez]

Hello,

I'll try and find a Windows machine to reproduce and fix this error.

[athalay]

It still doesn't work and it would be really helpful to allow Windows-users to build this project, because Realm-migration classes are not included in the currently released libraries!

Downloaded cygwin - contains no make, unnecessary to download.

Downloaded make-3.81, added make to PATH, made sure make is added to PATH, ran the gradlew command line and still got this:

That particular error is produced by the standalone toolchain creation script from Google. Which version of the NDK are you using? It looks like the one you are using does not support --platform=android-8

[upelsin]

Using NDK r10e.

I'm following steps described on the project's front page.
I've got make, JDK 8, API 19 & API 20, NDK r10e, and running ./gradlew androidJar.

Which steps / settings am I missing?

Thanks for help.

[emanuelez]

It looks like you're doing everything right.
We're not planning to actively add support for Windows right now, mainly because Google is working on the new NDK support, which we intend to use as soon as possible, and that will provide Windows support automatically.
Also, the new Migration API is just a pull request right now so I would not suggest to use it until at least we merge it into master, at which point you will be able to use our SNAPSHOT releases.

hi! I think the problem, or one of then, is that the gradle task using Bash Console, but in Windows you need to change all task to the CMD console.

^_^
for example:

The next method in gradle is for asking at git for the current branch of the project:

//this is the method for UNIX(MAC)
def workingBranchInUNIX = """git --git-dir=${rootDir}/.git
--work-tree=${rootDir}
rev-parse --abbrev-ref HEAD""".execute().text.trim()

//the same git command in windows:
def workingBranchInWindows = """cmd /c git --git-dir="${projectDir}.git" --work-tree="${projectDir}" rev-parse --abbrev-ref HEAD""".execute().text.trim()

Change all groovy code...no way! Maybe you can use Jitpack or Bitrise or another online tool for compile and forget do it in your local windows pc.

Realm now has a Dockerfile in the repo, so if you have Docker installed on any platform (Linux, Mac, Windows) you will be able to build Realm with the certainty of doing so with the perfect environment.

[david-perez]

How do I use the docker image to install Realm on my local Windows machine?
Wouldn't I have to mount the directory where I've downloaded the realm-java repo at the end of the Dockerfile, and then execute ./gradlew installRealmJava from inside the docker container?

[david-perez]

Could someone provide detailed instructions regarding the installation process using the docker image?
Has someone tested this on Windows?

[emanuelez]

From the repository folder:

docker build -t realm-java:latest .
docker run -ti -v <insert current folder here>:/tmp -w /tmp realm-java:latest bash

Once inside the image you should be able to run ./gradlew assemble

@cmelchior I didn't know you can use Docker to build Realm with some sort of black magic :smile:
