# 编译firefox38全过程

firefox编译过程需时较久，建议在服务器上搭建最小环境进行编译。此处创建最小环境（4.2.41-20160506）。
挂载dev proc sys后，chroot到最小环境中。

编译流程：（在环境配置、源码、及依赖包均已准备就绪的情况下）

```
# 进入编译目录
    cd gecko-dev
# 添加及修改firefox自带编译配置
    vi .mozconfig
# 开始编译
    ./mach build
# 本地化包
  # compare-locales
    easy_install -U compare-locales
  # build en_US package first
    cd obj-linux-unknow-linux-gnu
    make package
  # import zh_CN files
    cd obj-linux-unknow-linux-gnu/browser/locales
    make merge-zh-CN LOCALE_MERGEDIR=$(pwd)/mergedir
  # build zh_CN package
    make installers-zh-CN LOCALE_MEGEDIR=$(pwd)/mergedir
  # build zh-CN langpack not use
    make langpack-zh-CN LOCALE_MERGEDIR=$(pwd)/mergedir
```

## 1 获取firefox源码

### 1.1 浏览器代码库

公司内部git库镜像：

```
git@gitlab.rd.in.linx:mozilla/gecko-dev.git
```

或者github上的git库只读镜像

```
https://github.com/mozilla/gecko-dev.git
```

或者官方hg代码库

```
https://hg.mozilla.org/mozilla-central/
```

本次使用公司内部git库镜像，将master分支git clone下来后，选择切换到38版的最后一个esr版本。

切换到origin/GECKO3880esr_2016042017_RELBRANCH分支。

```
git checkout -b GECKO3880esr origin/GECKO3880esr_2016042017_RELBRANCH
```

注：GECKO38即为firefox38。
Fierfox有两种版本：普通版和ESR（Extended Support Release，延长支持）版。
ESR版本是Mozilla专门为那些无法或不愿每隔六周就升级一次的企业打造。Firefox ESR版的升级周期为42周。普通Firefox的升级周期为6周。

### 1.2 汉化包支持

由于下载后，需要使用hg进行管理。

编译mercurial(hg的源码包)。

Mercurial requires Python 2.6 or later.

需安装python2.6或以上版本。

编译Python2.7.12编译安装到/usr/local下,配置环境变量后，可编译通过mercurial。本次配置直接将Python2.7和之后所述的gcc5.2相关环境配置添加到.bashrc中。

```
export PATH=/usr/local/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/lib
```

使用hg clone http://hg.mozilla.org/releases/l10n/mozilla-release/zh-CN 克隆下汉化包，然后切换到对应的分支。

查找对应firefox38esr的zh_CN

```
cd zh_CN 
hg tags | grep -i firefox | grep -i esr | grep 38
```

## 2 firefox编译配置

### 2.1 配置文件.mozconfig

编译firefox之前，需要先配置firefox的编译配置（配置文件名称.mozconfig）。确定编译选项配置。

此处为编译使用的配置文件，拷贝到gecko-dev目录下即可。配置文件示例：

``` bash
#!/bin/bash
if [ "x$IS_NIGHTLY" = "xyes" ]; then
    # Some nightlies (eg: Mulet) don't want these set.
    MOZ_AUTOMATION_UPLOAD_SYMBOLS=${MOZ_AUTOMATION_UPLOAD_SYMBOLS-1}
    MOZ_AUTOMATION_UPDATE_PACKAGING=${MOZ_AUTOMATION_UPDATE_PACKAGING-1}
    MOZ_AUTOMATION_SDK=${MOZ_AUTOMATION_SDK-1}
fi

### 2.2 配置ccache

由于firefox编译过程用时较长，建议配置ccache，可更快调试编译firefox。

首先配置环境变量：
```
export CCACHE_COMPRESS=""
```

然后配置firefox编译配置文件.mozconfig，打开ccache配置选项。

```
#启用ccache，便于编译调试
ac_add_options --with-ccache=/usr/bin/ccache
```


## 3 编译过程及报错解决办法

此段详细记录了编译过程中遇到的报错及解决报错问题的方法。

### 3.1 autoconf-2.13问题

准备好环境和源码包后
```
linx:~/gecko-dev # ./mach build/
We're assuming the 'build/' command is 'build' and we're executing it for you.

0:00.73 /usr/bin/make -f client.mk -s
0:01.26 client.mk:201: /root/gecko-dev/obj-x86_64-unknown-linux-gnu/.mozconfig.mk: 没有那个文件或目录
0:01.73 Clobber not needed.
0:03.21 Adding client.mk options from :

0:03.21     OBJDIR=/root/gecko-dev/obj-x86_64-unknown-linux-gnu
0:03.23 /root/gecko-dev/client.mk:304: *** Could not find autoconf 2.13。 停止。
0:03.23 make: *** [build] 错误 2
0:03.25 0 compiler warnings present.
0:03.25 Failed to parse ccache stats output: cache hit                              0
linx:~/gecko-dev # ./mach build
0:00.31 /usr/bin/make -f client.mk -s
0:01.79 Adding client.mk options from :
0:01.79     MOZ_OBJDIR=/root/gecko-dev/obj-x86_64-unknown-linux-gnu
0:01.79     OBJDIR=/root/gecko-dev/obj-x86_64-unknown-linux-gnu
0:01.81 /root/gecko-dev/client.mk:304: *** Could not find autoconf 2.13。 停止。
0:01.81 make: *** [build] 错误 2

0:01.84 Failed to parse ccache stats output: cache hit                              0
linx:~/gecko-dev # ls build/
```

解决：

借鉴如下，网上资料：
```
wget http://ftp.gnu.org/gnu/autoconf/autoconf-2.13.tar.gz
tar -xvzf autoconf-2.13.tar.gz
cd autoconf-2.13/
./configure --program-suffix=2.13
make
sudo make install
You may need to export AUTOCONF=autoconf2.13 in your environment (e.g. put it in .profile in your home directory) or add this line to your .mozconfig file:
```
修改为autoconf2.13进行编译，安装到/usr/local下,并在安装目录创建软链接 ln -s autoconf2.13 autoconf

在.mozconfig中配置autoconf2.13
```
mk_add_options AUTOCONF=autoconf2.13
```


### 3.2 .mozconfig 里设置字体位置

```

0:06.72 Failed to parse ccache stats output: cache hit                              0
linx:~/gecko-dev # ls

```

解决：

注意字体包目录的位置，以下为例：（gecko-dev在/root下，zh-CN在/root/zh-CN下）

```
linx:~/gecko-dev # pwd
/root/gecko-dev
linx:~/gecko-dev # cd ../zh-CN/zh-CN/
linx:~/zh-CN/zh-CN # pwd
/root/zh-CN/zh-CN
```

在.mozconfig中配置指定字体位置

```
ac_add_options --with-l10n-base=$topsrcdir/../zh-CN
```


### 3.3. gcc版本升级

```
0:04.04 configure:3787: checking for otool
0:04.04 configure: error: Only GCC 4.7 or newer supported
0:04.04 *** Fix above errors and then restart with\

0:04.04 make[2]: *** [configure] Error 1
0:04.04 make[1]: *** [/root/gecko-dev/obj-x86_64-unknown-linux-gnu/Makefile] Error 2
0:04.04 make: *** [build] Error 2
0:04.09 0 compiler warnings present.
0:05.09 Failed to parse ccache stats output: cache hit                        
```

解决：

由于有编译好的可用的gcc-5.2，故安装gcc-5.2。并配置环境变量。
安装gcc-5.2到/usr/lolcal下，需要配置环境变量。

```
export PATH=/usr/local/gcc-5.2/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/gcc-5.2/lib64:$LD_LIBRARY_PATH
```

### 3.4 libffi >= 3.0.9 (编译依赖，运行依赖)

0:12.14 Failed to parse ccache stats output: cache hit                              0
linx:~/gecko-dev # 
```

解决：

直接在当前最小环境下编译即可。

创建libffi目录，在目录下，下载源码libffi-3.2.1.tar.gz，然后mkpkgfile，再进行编译即可。

安装需要 -f 参数安装。

```
linx:~/libffi # pkgadd libffi#3.2.1-x86_64-linx-Rocky4.2.pkg.tar.gz 
usr/lib64/libffi.a
usr/lib64/libffi.la
usr/lib64/libffi.so
usr/share/info/dir
pkgadd: listed file(s) already installed (use -f to ignore and overwrite)
```

0:10.49 Failed to parse ccache stats output: cache hit                             45
linx:~/gecko-dev # ls

```
需直接在当前环境下进行编译gtk2-2.18.9

注意需使用我们的applications.git库中的编译目录及方法进行。去掉Pkgfile中gtkclipboard.patch

pkgadd -u gtk2...　安装。

注意：此包的lib64下的库文件，在最后打包firefox时，需要添加到firefox包中。


### 3.6 pango >= 1.22.0（编译依赖，运行依赖）

```
0:09.45 configure:17411: checking MOZ_GTK2_CFLAGS
0:09.45 configure:17416: checking MOZ_GTK2_LIBS

linx:~/gecko-dev # pkginfo -i |grep pango
```

此包编译方法与上述gtk2编译相同。此处编译pango-1.26.2

注意：此包的lib64下的库文件，在最后打包firefox时，需要添加到firefox包中。

```

解决：

升级binutils和libtool。

编译binutils-2.21到/usr/local/下，改名为binutils2.11#2.11-...tar.gz

libtool-2.4.6直接在本环境下mkpkgfile然后pkgmk编译即可。

### 3.12 编译完成

综上，成功编译完成。

## 4 打包及本地化

编译完成后，需先将编译结果打包成en_US版firefox，然后再将其添加zh_CN并打包成zh_CN版的firefox包，最后需将包解压并修改启动文件库和替换gtk/pango的库，打包制作成我们的pkg包。

## 4.1 打包en_US版firefox

### 4.1.1 compare-locales

```
easy_install -U compare-locales
```

默认会使用Python2.5对应的easy_install，但是本环境配置使用Python2.7，故需在本环境配置下，重新编译python-setuptools。即，使用applications库中的源码在本环境下编译即可，注意需修改包名并将其编译安装到/usr/local下。

由于执行easy_install连接不到python的官网，故手动编译compare-locales安装包。在本环境下，下载compare-locales-1.0，然后mkpkgfile，在Pkgfile中python setup.py install指定编译安装到/usr/local中。

安装python-setuptools和compare-locales后，执行如下：

```
linx:~/python-setuptools # easy_install -U compare-locales
Searching for compare-locales
Reading http://pypi.python.org/simple/compare-locales/

linx:~/python-setuptools # 
```

### 4.1.2 生成en_US版firefox

执行如下命令，打包。

```
cd obj-x86_64-unknown-linux-gnu
make package
```

执行过后，在obj-x86_64-unknown-linux-gnu/dist中会生成firefox-38.8.0.en-US.linux-x86_64.tar.bz2，但是查看发现此包大小不对，打包失败。当前目录下已经生成firefox的目录。

查看make package的打包过程。找到如下打包命令：

```
cd ../../dist && (cd firefox && /root/gecko-dev/obj-x86_64-unknown-linux-gnu/_virtualenv/bin/python /root/gecko-dev/config/createprecomplete.py) && gnutar -c --owner=0 --group=0 --numeric-owner --mode=go-w --exclude=.mkdir.done -f - firefox | bzip2 -vf > firefox-38.8.0.en-US.linux-x86_64.tar.bz2
#
```

即，打包使用的是gnutar的命令。此命令打包失败。备份此命令，然后创建软件接指向tar命令，然后重新打包。

```
mv /bin/gnutar{,.bak}
ln -s /bin/tar /bin/gnutar
cd obj-x86_64-unknown-linux-gnu
make package
```

打包成功。

## 4.2 制作zh_CN版firefox

打包en_US后，即可打包制作zh_CN版。执行如下：

``` 
cd obj-x86_64-unknown-linux-gnu/browser/locales
#import zh-CN files
make merge-zh-CN LOCALE_MERGEDIR=$(pwd)/mergedir
#build zh-CN package
make installers-zh-CN LOCALE_MERGEDIR=$(pwd)/mergedir
#build zh-CN langpack not use
make langpack-zh-CN LOCALE_MERGEDIR=$(pwd)/mergedir
```

此处，制作过程中曾出现报错，原因时easy_install那一步寻找使用的python2.5中的模块，导致此时报错，如下：

```
linx:~/gecko-dev/obj-x86_64-unknown-linux-gnu/browser/locales # make merge-zh-CN LOCALE_MERGEDIR=$(pwd)/mergedir
rm -f -rf /root/gecko-dev/obj-x86_64-unknown-linux-gnu/browser/locales/mergedir
MACOSX_DEPLOYMENT_TARGET= compare-locales -m /root/gecko-dev/obj-x86_64-unknown-linux-gnu/browser/locales/mergedir /root/gecko-dev/browser/locales/l10n.ini /root/zh-CN zh-CN

linx:~/gecko-dev/obj-x86_64-unknown-linux-gnu/browser/locales # 

```

解决，即如4.1.1所述，进行修改。

## 4.3 测试并制作rocky6.0.42系统的firefox38安装包

制作完成zh_CN版的firefox后，接下来就可以整理打包成我们的rocky6.0.42系统中的安装包。

我们接下来要用到的包及库等内容有：

1.firefox—zh_CN编译完成包：firefox-38.8.0.zh-CN.linux-x86_64.tar.bz2

2.在编译过程中需要的依赖包（同时是运行依赖的包）：libffi gtk2 pango

### 4.3.1 添加运行依赖库并测试运行

解压firefox-38.8.0.zh-CN.linux-x86_64.tar.bz2到20160513版测试虚拟机的root下。

添加运行依赖库，在解压后的目录firefox中创建新目录lib，分别拷贝libffi-3.2.1/gtk2-2.18.9/pango-1.26.2的/usr/lib64/下的*.a/*.so库文件到firefox/lib下。使用如下命令拷贝软链接：

```
rsync -l lib firefox/
```

修改firefox启动脚本中的运行依赖库，修改firefox/run-mozilla.sh

```
--- run-mozilla.sh~	2016-10-20 13:25:33.000000000 +0800
+++ run-mozilla.sh	2016-11-02 13:36:03.000000000 +0800

 if [ -n "$LD_LIBRARYN32_PATH" ]
```

然后可以运行./run-mozilla.sh ./firefox启动测试，并测试输入中文可用。

### 4.3.2 制作rocky6.0.42系统安装包

创建工作目录work，然后首先在其中创建opt目录，并将4.3.1修改过的目录firefox放到opt目录下。

然后，创建如下所需目录：注意此处只是需要创建目录，文件在后续会有说明。

```
etc/
etc/ld.so.conf.d
etc/ld.so.conf.d/firefox.ld.conf
opt/
opt/firefox/
...

usr/lib/mozilla
usr/lib/mozilla/plugins
usr/lib/mozilla/plugins/libnpjp2.so
var/
var/lib
var/lib/pkg
var/lib/pkg/firefox.post_add
```

firefox.ld.conf依赖库配置：

```
#cat  etc/ld.so.conf.d/firefox.ld.conf 
/opt/firefox
```

firefox启动命令，菜单软链接启动项及软链接库创建

```
linx:~/work/$ cat  usr/bin/firefox 
#!/bin/bash

/opt/firefox/run-mozilla.sh /opt/firefox/firefox

linx:~/work/$ ls -l  usr/lib/mozilla/plugins/libnpjp2.so 
lrwxrwxrwx 1 sxx sxx 40 5月  13 14:04 usr/lib/mozilla/plugins/libnpjp2.so -> /usr/lib64/jdk/jre/lib/amd64/libnpjp2.so

Comment=Web Browser
Exec=/opt/firefox/run-mozilla.sh /opt/firefox/firefox
Icon=/opt/firefox/browser/icons/mozicon128.png
Terminal=false
Type=Application
Categories=Application;Network;
```

还需添加安装包的安装后执行的ldconfig

```
linx:~/work/$ cat var/lib/pkg/firefox.post_add 
#!/bin/bash
ldconfig
```

按以上配置修改后，查看文件的属组及权限，并进行打包。

1.添加的脚本需要运行权限。

2.work目录下的各文件属组均为root.root

3.特别注意：因work目录下的所有文件会安装到系统的/目录下，故注意在work目录下执行ls -la时"."".."两个的属组为root.root权限均为755。

最后，可以在work目录下执行打包命令：
```
tar cfz ../firefox#38.8.0-x86_64-linx-Rocky4.3.pkg.tar.gz  ./*
```

## 5 结束

最后获得的firefox#38.8.0-x86_64-linx-Rocky4.3.pkg.tar.gz安装包可直接用pkgadd命令进行安装。
