在centos7下spice代碼編譯

在centos7下spice代碼編譯

目标還是兩個spice的包：spice-protocol和spice-gtk

rpm -q xxx（查詢 已安裝的rpm包）

rpm -e –nodeps xxx

由于yum安裝和移除都會處理依賴關系，是以移除原有老版本的spice包的時候，需要用rpm

rpm -e –nodeps xxx

配置的時候，需要增加幾個選項，适應centos的風格

$ ./configure –prefix=/usr –localstatedir=/var –sysconfdir=/etc –libdir=/usr/lib64

spice-protocol spice spice-gtk都是從git上clone來的。

1）安裝virt-manager

yum install virt-manager

相關的包會安裝好，而且可以運作

2）spice-protocol

rpm -e –nodeps spice-protocol

./autogen

./configure –prefix=/usr –localstatedir=/var –sysconfdir=/etc –libdir=/usr/lib64

make

make install

3）spice

rpm -e –nodeps spice-server-0.12.4-20.el7_3.x86_64

yum install glib2-devel pixman-devel celt051-devel openssl-devel libjpeg-turbo-devel cyrus-sasl-devel alsa-lib-devel libcacard-devel

yum install gstreamer1 gstreamer1-plugins-base-devel gstreamer1-plugins-bad-free gstreamer1-plugins-bad-free-devel gstreamer1-plugins-base-tools

yum install epel-release

yum install lz4 lz4-devel

yum install gstream1-plugins-ugly gstream1-libav

（然後加nux的repo，直接安裝gstream1-plugins-ugly和gstream1-libav）

./configure –prefix=/usr –localstatedir=/var –sysconfdir=/etc –libdir=/usr/lib64

make

make install

（git clone下來的spice編譯出錯，還是下載下傳0.13.3）

不建議編譯代碼，要涉及很多codec。

（

另外在centos中，沒有gstreamer-plugin-ugly和gstreamer-libav，需要下載下傳源代碼編譯。

https://gstreamer.freedesktop.org/modules/

不能最新的版本，目前yum的倉庫的gstream1是1.4.5

那ugly和libav都是下載下傳的1.4.5

）

4）spice-gtk

把原來的spice glib gtk都解除安裝

yum install perl-Text-CSV

yum install gtk-doc

yum install gtk3-devel

yum install libepoxy-devel

yum install vala vala-tools

yum install pulseaudio-libs-devel

yum install usbredir-devel usbredir-server usbredir

./autogen.sh

./configure –prefix=/usr –localstatedir=/var –sysconfdir=/etc –libdir=/usr/lib64 –enable-vala

make

make install

5）qemu和支援video的codec

qemu目前的版本無法設定spice的video codec，目前最新版本，以及git下的代碼都沒有設定spice codec的代碼，找到一個patch可以做這個事情，需要自己重新編譯。

https://patchwork.freedesktop.org/patch/78976/

根據patch，修改qemu-options.hx和ui/spice-core.c

打算把目前系統裡面的qemu全部删除掉。

http://wiki.qemu-project.org/Hosts/Linux

yum install git glib2-devel libfdt-devel pixman-devel zlib-devel

（通過src rpm 安裝1.5.3的qemu失敗，雖然可以通過修改spec以及增加patch，直接編譯，但是spice的experiment的頭檔案，以及很多變量已經失效，編譯warning，而且編譯要求warning即error，無法編譯通過）

更改方案，既然是qemu設定spice的參數，那直接在spice代碼中寫上這個參數，或者通過配置檔案加載，而不是通過qemu。

H264編碼使用：

1）通過google搜尋“(qemu-kvm:5360): Spice-WARNING **: gstreamer-encoder.c:775:map_format: The 8 format has not been tested yet”發現，spice出現類似的問題，并且在開了一個bug，但是未有解決

https://bugs.freedesktop.org/show_bug.cgi?id=97786

https://lists.freedesktop.org/archives/spice-devel/2016-February/026279.html

後來直接通過公司内網的repo，直接安裝了qemu的2.3rpm，消除了問題。

但是不能确認是否是264編碼。通過網頁播放flash完全無法确認。試圖通過本地視訊播放，看看是否可以确認建立video的編碼。
