下载

• 在Bitbucket上可以下载到最新的版本（截止目前为0.14版）

• 或者直接用wget下载

wget "https://bitbucket.org/odedevs/ode/downloads/ode-0.14.tar.gz"

编译

假设安装到/usr下

# 解压

tar xf ode-0.14.tar.gz

cd ode-0.14

# 依赖安装

sudo apt install automake -y

# 配置

./bootstrap

./configure --prefix=/usr --enable-double-precision --enable-static=PKGS --with-drawstuff=X11 --with-trimesh=opcode --enable-demos --enable-libccd

# --prefix=/usr  安装到/usr下，不加这一项则默认安装到/usr/local下

# --enable-double-precision  启用双精度浮点数

# --enable-static=PKGS 生成静态链接库

# --with-drawstuff=X11  启用极简图形库，基于X11

# --enable-demos  例子啦╮(╯▽╰)╭

# --enable-libccd 碰撞检测库

make   # 编译啦╮(╯_╰)╭

安装

sudo make install   # 安装啦

echo '╮(╯▽╰)╭'

注意，由于drawstuff没有默认安装_(:3」∠)_，因此需要手动安装。

sudo mkdir /usr/include/drawstuff

sudo cp ./include/drawstuff/drawstuff.h ./include/drawstuff/version.h /usr/include/drawstuff

sudo cp ./drawstuff/src/.lib/libdrawstuff.a ./drawstuff/src/.lib/libdrawstuff.la /usr/lib

# 更新库缓存

sudo ldconfig

使用库

drawstuff在链接时需要同时链接X11、GL、GLU、m这些库，若使用cmake，可以添加这一句：

target_link_libraries(target ode drawstuff X11 GLU GL m)

另外，drawstuff需要贴图，有自带的，位于<ode-0.14>/drawstuff/textures/下。需要自行复制到工程目录下。
