i386 vs. AMD64 ABI Differences

问题 Where can I find all the differences in data types between the i386 & AMD64 Application Binary Interface(ABI)s ? I know that the long type is 32-bit in i386 ABI & 64-bit in AMD64. Is this correct? 回答1: I suggest you download Dr Agner Fog's optimization manuals. He has a manual specifically about ABIs and their differences. For differences in the instruction set between 32-bit mode and 64-bit mode, both Intel and AMD's instruction manuals should cover this in the introductory volume or the

Building ffmpeg iOS libraries for armv7, armv7s, arm64, i386 and universal

问题 I have seen several scripts to build FFmpeg API for armv7, 7s and i386 but couldn't find anything which would work for armv64 as well. Some of the answers on other threads of this forum suggested to prepare a separate library for arm64 but it does not work well with rest of the architectures. Hence I need a script which can work for all the supported architectures for iOS including armv7, armv7s, armv64 and i386. 回答1: I have use below scripts for making FFmpeg build for arm64 https://github

1、JDK安装 a.准备 由于AS（Android Studio）不支持openjdk，需要另行下载oracle jdk，同时官网指出对于64位linux系统，为了能在其上运行32位程序，需要安装一些软件，执行以下命令 ubuntu 13.10及以上系统 #sudo dpkg --add-architecture i386 #sudo apt-get update #sudo apt-get install libncurses5:i386 libstdc++6:i386 zlib1g:i386 ubuntu 13.04及以下系统 #apt-get install ia32-libs b.安装jdk #sudo mkdir /usr/lib/jvm/ #sudo tar -zxvf jdk-8u51-linux-x64.tar.gz -C /usr/lib/jvm c.配置环境变量 编辑/etc/profile的话是对系统所有用户做环境配置，不建议这么做，而是直接配置当前用户 #sudo gedit ~/.bashrc 给文件添加如下内容 export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_45 export JRE_HOME=${JAVA_HOME}/jre export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}

rpm安装总结

在RedHat Linux和Mandrake等兼容RedHat的发行版中，整个发行版都是利用RPM安装的。所以安装新软件的最好方 法是从网络上下载rpm包。 1）用RPM安装软件包，最简单的命令如下： # rpm -ivh foo-1.0-l.i386.rpm （这里讲的软件包是foo-1.0-l.i386.rpm，以下都是） foo#################### 下面rpm就会输出该软件包的名称，并显示一个状态条。安装很简单。 2）拆除已安装的软件包 要反安装软件包foo，只需输入以下这行命令： # rpm -e foo 注意：软件包名是foo，而不是rpm文件名"foo-1.0-l.i386.rpm"。 3）升级软件包 升级软件类似于安装软件： # rpm -Uvh foo-2.0-l.i386.rpm foo#################### 用户要注意的是：rpm会自动反安装相应软件包的老版本。如果老版本软件的配置文件通新版本的不兼容，rpm会自动将其保存为另外一个文件，用户会看到下面的信息： saving /etc/foo.conf as /etc/foo.conf.rpmsave 这样用户就可以自己手工去更改相应的配置文件。 另外如果用户要安装老版本的软件，用户就会看到下面的出错信息： # rpm -Uvh foo-1.0-l.i386.rpm foo

Build Multiarch OpenSSL on OS X

I need to build OpenSSL on OS X for 32 and 64 bit architectures. What are the options I need to give to ./Configure so that I get it built for both architectures into same .a file? jww ./Configure so that I get it built for both architectures into same .a file? You have to be careful with OpenSSL and multiarch libraries because the library is not multiarch safe. That's because each configuration has its own <openssl/opensslconf.h> file, and each platform's BIGNUM is different. Supplying -arch x86_64 -arch i386 will result in a build failure because of the way OpenSSL's build system forms
