一直想自己编译一个群晖上的 aria2 ，正好国庆假期，自己折腾下，这里是折腾过程的流水账，仅作记录之用。

搭建官方编译环境

找到了官方文档，搭建似乎很容易:
官方的文档 DSM_Developer_Guide

编译环境的需求如下：
- 64bit linux environment.
- Bash (>= 4.1.5)
- Python (>= 2.7.3)
建立工作目录

mkdir -p /toolkit/

下载toolkit

cd /toolkit/
git clone https://github.com/SynologyOpenSource/pkgscripts-ng.git

更新环境

version="6.1"
platform="armada375"
cd /toolkit/pkgscripts-ng
./EnvDeploy -v ${version} -p ${platform}

/toolkit
├── build_env
│   └── ds.armada375-6.1
├── pkgscripts-ng
│   ├── CodeSign.php
│   ├── EnvDeploy
│   ├── include
│   ├── PkgCreate.py
│   ├── ProjectDepends.py
│   ├── README.md
│   ├── SynoBuild
│   └── SynoInstall
└── toolkit_tarballs
    ├── base_env-6.1.txz
    ├── ds.armada375-6.1.dev.txz
    └── ds.armada375-6.1.env.txz

进入 chroot 环境

sudo chroot /toolkit/build_env/ds.armada375-6.1

继续看文档发现，这是编译官方安装的环境，我似乎不需要弄这么复杂，弃坑。

搭建交叉编译环境

根据 NAS 型号，选择编译器
armada375-gcc493_glibc220_hard-GPL.txz
解压文件到 /usr/local

tar -zJf armada375-gcc493_glibc220_hard-GPL.txz /usr/local
cp -rf /usr/local/arm-unknown-linux-gnueabi/* /usr/local/

编译依赖库

在 github 上搜索了下有人写好了编译的脚本,aria2-static-builds

嗯，自己修改了下

#!/bin/bash

# In this configuration, the following dependent libraries are compiled:
#
# * zlib
# * c-ares
# * expat
# * sqlite3
# * openSSL
# * libssh2

#CHECK TOOL FOR DOWNLOAD
 aria2c --help > /dev/null
 if [ "$?" -eq 0 ] ; then
   DOWNLOADER="aria2c --check-certificate=false"
 else
   DOWNLOADER="wget -c"
 fi

make

make -j4 V=s

链接时遇到一些小问题，库的位置不对，复制下。

cp /usr/local/arm-unknown-linux-gnueabi/arm-unknown-linux-gnueabi/sysroot/lib/* /usr/local/arm-unknown-linux-gnueabi/arm-unknown-linux-gnueabi/lib/

install

make install

优化编译出的二进制文件

arm-unknown-linux-gnueabi-strip -s /opt/aria2-arm-unknown/bin/armle-unknown-linux-aria2c

其他

修改 max-connections-per-server 默认值
- 自己修改 OptionHandlerFactory.cc 源代码就好
- 具体详见这里 How can i build aria2c with max-connections-per-server more than 16
