-## Prepare seafile source code
-
-To build seafile server, there are four sub projects involved:
-
-* [libsearpc](https://github.com/haiwen/libsearpc)
-* [ccnet-server](https://github.com/haiwen/ccnet-server)
-* [seafile-server](https://github.com/haiwen/seafile-server)
-* [seahub](https://github.com/haiwen/seahub)
-
-The build process has two steps:
-
-* First, fetch the tags of each projects, and make a soruce tarball for each of them.
-* Then run a `build-server.py` script to build the server package from the source tarballs.
-
-### Fetch git tags and prepare source tarballs
-
-Seafile manages the releases in tags on github.
-
-Assume we are packaging for seafile server 6.0.1, then the tags are:
-
-* ccnet-server, seafile-server, and seahub would all have a `v6.0.1-sever` tag.
-* libsearpc would have the `v3.0-latest` tag (libsearpc has been quite stable and basically has no further development, so the tag is always `v3.0-latest`)
-
-First setup the `PKG_CONFIG_PATH` enviroment variable (So we don't need to make and make install libsearpc/ccnet/seafile into the system):
-
-```
-export PKG_CONFIG_PATH=/home/pi/dev/seafile/lib:$PKG_CONFIG_PATH
-export PKG_CONFIG_PATH=/home/pi/dev/libsearpc:$PKG_CONFIG_PATH
-export PKG_CONFIG_PATH=/home/pi/dev/ccnet:$PKG_CONFIG_PATH
-
-```
-
-### libsearpc
-
-```
-cd ~/dev
-git clone https://github.com/haiwen/libsearpc.git
-cd libsearpc
-git reset --hard v3.0-latest
-./autogen.sh
-./configure
-make dist
-
-```
-
-### ccnet
-
-```
-cd ~/dev
-git clone https://github.com/haiwen/ccnet-server.git
-cd ccnet
-git reset --hard v6.0.1-server
-./autogen.sh
-./configure
-make dist
-
-```
-
-### seafile
-
-```
-cd ~/dev
-git clone https://github.com/haiwen/seafile-server.git
-cd seafile
-git reset --hard v6.0.1-server
-./autogen.sh
-./configure
-make dist
-
-```
-
-### seahub
-
-```
-cd ~/dev
-git clone https://github.com/haiwen/seahub.git
-cd seahub
-git reset --hard v6.0.1-server
-./tools/gen-tarball.py --version=6.0.1 --branch=HEAD
-
-```
-
-### seafobj
-
-```
-cd ~/dev
-git clone https://github.com/haiwen/seafobj.git
-cd seafobj
-git reset --hard v6.0.1-server
-make dist
-
-```
-
-### seafdav
-
-```
-cd ~/dev
-git clone https://github.com/haiwen/seafdav.git
-cd seafdav
-git reset --hard v6.0.1-server
-make
-
-```
-
-### Copy the source tar balls to the same folder
-
-```
-mkdir ~/seafile-sources
-cp ~/dev/libsearpc/libsearpc--tar.gz ~/seafile-sources
-cp ~/dev/ccnet/ccnet--tar.gz ~/seafile-sources
-cp ~/dev/seafile/seafile--tar.gz ~/seafile-sources
-cp ~/dev/seahub/seahub--tar.gz ~/seafile-sources
-
-cp ~/dev/seafobj/seafobj.tar.gz ~/seafile-sources
-cp ~/dev/seafdav/seafdav.tar.gz ~/seafile-sources
-
-```
-
-### Run the packaging script
-
-Now we have all the tarballs prepared, we can run the `build-server.py` script to build the server package.
-
-```
-mkdir ~/seafile-server-pkgs
-~/dev/seafile/scripts/build-server.py --libsearpc_version= --ccnet_version= --seafile_version= --seahub_version= --srcdir= --thirdpartdir=/home/pi/dev/seahub_thirdpart --srcdir=/home/pi/seafile-sources --outputdir=/home/pi/seafile-server-pkgs
-
-```
-
-After the script finisheds, we would get a `seafile-server_6.0.1_pi.tar.gz` in `~/seafile-server-pkgs` folder.
-
-## Test the built package
-
-### Test a fresh install
-
-
-
-The test should cover these steps at least:
-
-* The setup process is ok
-* After `seafile.sh start` and `seahub.sh start`, you can login from a browser.
-* Uploading/Downloading files through a web browser works correctly.
-* Seafile [WebDAV](../extension/webdav.md) server works correctly
-
-### Test upgrading from a previous version
-
-* Download the package of the previous version seafile server, and setup it.
-* Upgrading according to [the manual](../upgrade/upgrade.md)
-* After the upgrade, check the functionality is ok:
- * Uploading/Downloading files through a web browser works correctly.
- * Seafile [WebDAV](../extension/webdav.md) server works correctly
