# Build scripts that publish pre-compiled protoc artifacts |
|
``protoc`` is the compiler for ``.proto`` files. It generates language bindings |
|
for the messages and/or RPC services from ``.proto`` files. |
|
|
|
Because ``protoc`` is a native executable, the scripts under this directory |
|
build and publish a ``protoc`` executable (a.k.a. artifact) to Maven |
|
repositories. The artifact can be used by build automation tools so that users |
|
would not need to compile and install ``protoc`` for their systems. |
|
|
|
## Versioning |
|
The version of the ``protoc`` artifact must be the same as the version of the |
|
Protobuf project. |
|
|
|
## Artifact name |
|
The name of a published ``protoc`` artifact is in the following format: |
|
``protoc-<version>-<os>-<arch>.exe``, e.g., ``protoc-3.0.0-alpha-3-windows-x86_64.exe``. |
|
|
|
## System requirement |
|
Install [Apache Maven](http://maven.apache.org/) if you don't have it. |
|
|
|
The scripts only work under Unix-like environments, e.g., Linux, MacOSX, and |
|
Cygwin or MinGW for Windows. Please see ``README.md`` of the Protobuf project |
|
for how to set up the build environment. |
|
|
|
## To install artifacts locally |
|
The following command will install the ``protoc`` artifact to your local Maven repository. |
|
``` |
|
$ mvn install |
|
``` |
|
|
|
## Cross-compilation |
|
The Maven script will try to detect the OS and the architecture from Java |
|
system properties. It's possible to build a protoc binary for an architecture |
|
that is different from what Java has detected, as long as you have the proper |
|
compilers installed. |
|
|
|
You can override the Maven properties ``os.detected.name`` and |
|
``os.detected.arch`` to force the script to generate binaries for a specific OS |
|
and/or architecture. Valid values are defined as the return values of |
|
``normalizeOs()`` and ``normalizeArch()`` of ``Detector`` from |
|
[os-maven-plugin](https://github.com/trustin/os-maven-plugin/blob/master/src/main/java/kr/motd/maven/os/Detector.java). |
|
Frequently used values are: |
|
- ``os.detected.name``: ``linux``, ``osx``, ``windows``. |
|
- ``os.detected.arch``: ``x86_32``, ``x86_64`` |
|
|
|
For example, MingGW32 only ships with 32-bit compilers, but you can still build |
|
32-bit protoc under 64-bit Windows, with the following command: |
|
``` |
|
$ mvn install -Dos.detected.arch=x86_32 |
|
``` |
|
|
|
## To push artifacts to Maven Central |
|
Before you can upload artifacts to Maven Central repository, make sure you have |
|
read [this page](http://central.sonatype.org/pages/apache-maven.html) on how to |
|
configure GPG and Sonatype account. |
|
|
|
You need to perform the deployment for every platform that you want to |
|
suppport. DO NOT close the staging repository until you have done the |
|
deployment for all platforms. Currently the following platforms are supported: |
|
- Linux (x86_32 and x86_64) |
|
- Windows (x86_32 and x86_64) with |
|
- Cygwin with MinGW compilers (both x86_32 and x86_64) |
|
- MSYS with MinGW32 (x86_32 only) |
|
- MacOSX (x86_32 and x86_64) |
|
|
|
Use the following command to deploy artifacts for the host platform to a |
|
staging repository. |
|
``` |
|
$ mvn clean deploy -P release |
|
``` |
|
It creates a new staging repository. Go to |
|
https://oss.sonatype.org/#stagingRepositories and find the repository, usually |
|
in the name like ``comgoogle-123``. |
|
|
|
You will want to run this command on a different platform. Remember, in |
|
subsequent deployments you will need to provide the repository name that you |
|
have found in the first deployment so that all artifacts go to the same |
|
repository: |
|
``` |
|
$ mvn clean deploy -P release -Dstaging.repository=comgoogle-123 |
|
``` |
|
|
|
A 32-bit artifact can be deployed from a 64-bit host with |
|
``-Dos.detected.arch=x86_32`` |
|
|
|
When you have done deployment for all platforms, go to |
|
https://oss.sonatype.org/#stagingRepositories, verify that the staging |
|
repository has all the binaries, close and release this repository. |
|
|
|
### Tips for deploying on Windows |
|
Under Windows the following error may occur: ``gpg: cannot open tty `no tty': |
|
No such file or directory``. This can be fixed by configuring gpg through an |
|
active profile in ``.m2\settings.xml`` where also the Sonatype password is |
|
stored: |
|
```xml |
|
<settings> |
|
<servers> |
|
<server> |
|
<id>ossrh</id> |
|
<username>[username]</username> |
|
<password>[password]</password> |
|
</server> |
|
</servers> |
|
<profiles> |
|
<profile> |
|
<id>gpg</id> |
|
<properties> |
|
<gpg.executable>gpg</gpg.executable> |
|
<gpg.passphrase>[password]</gpg.passphrase> |
|
</properties> |
|
</profile> |
|
</profiles> |
|
<activeProfiles> |
|
<activeProfile>gpg</activeProfile> |
|
</activeProfiles> |
|
</settings> |
|
``` |
|
|
|
### Tested build environments |
|
We have succesfully built artifacts on the following environments: |
|
- Linux x86_32 and x86_64: Ubuntu 14.04.2 64-bit |
|
- Windows x86_32: MSYS with ``mingw32-gcc-g++ 4.8.1-4`` on Windows 7 64-bit |
|
- Windows x86_64: Cygwin64 with ``mingw64-x86_64-gcc-g++ 4.8.3-1`` on Windows 7 64-bit |
|
- Mac OS X x86_32 and x86_64: Mac OS X 10.9.5
