在尝试使用as进行编译时遇到operandtypemismatchforpush错误，这通常是因为编译的代码与运行环境位数不匹配。解决办法包括在指令文件头部添加.code32声明32位代码，或者将%eax替换为%rax以适应64位环境。问题根源在于重定位文件与机器位数不兼容。

使用as进行编译的时候报错operand type mismatch for push'等。

  • 两种解决方案：

①在指令文件头部中加.code32

在这里插入图片描述
②将指令文件中的%eax改为%rax也可以解决问题

原因：重定位文件是32位，机器是64位，不兼容出现的问题。

关于初始代码的处理    原始代码很老，所以需要需要用32位系统编译，当然64位系统可以模拟这一过程，gcc与g++ 编译器支持32位程序的方法（以gcc为例）  （1）确认主机为64位架构的内核，应该输出为adm64,执行： $ dpkg --print-architecture； （2）确认打开了多支架功能，应该输出为i386,执行： $ dpkg --print-foreign-arc...

《Linux内核完全剖析》这本书在第4章给出了一个简单多任务内核示例程序，我们称之为Linux 0.00系统。本文介绍了一种把它跑起来的方法。

由于给原来RHEL分配的空间太少，故而重新装了下系统。安装ffmpeg时候遇到如下的问题： libavcodec/x86/h264_qpel_mmx.c: Assembler messages: libavcodec/x86/h264_qpel_mmx.c:1294: Error: operand type mismatch for `cmp' libavcodec/x86/h264_qpe
ffmpeg编译 Error: operand type mismatch for `shr‘

具体是因为什么我也不是太清楚，我是在Windows下的MSYS2中make编译，我猜测是gcc版本的问题，我的ffmpeg源码比较老，是2018年的，我通过MSYS2下载了 mingw64 编译工具链，其中的gcc版本为：13.2.0。参考链接：https://fftrac-bg.ffmpeg.org/ticket/10405。这些错误是由于汇编代码中存在类型不匹配的错误，导致无法通过汇编阶段编译。将ffmpeg源码中 mathops.h 中的如下代码做一个修改。

在反复检查脚本编写，以及文件路径都没有问题过后，通过网上相关论坛的得知这是通常与编译代码时使用了不匹配的操作数；类型有关，特别是在汇编语言或低级编程中可能会出现。新版的ffmpeg当中修复了这个问题，新版对ffmpeg源码当中 libavcodec/x86/mathops.h 文件做了一些修改。新的文件做了如下的修改。将我们 libavcodec/x86/mathops.h文件当中的对应的函数修改之后完成了编译。以上就是我在编译ffmpeg过程当中遇到的问题。

可能的解决方法包括修改指令后缀，例如将pushl改为push，如果使用的是64位汇编器，可能需要使用正确的操作数大小。另外，检查操作数的顺序是否符合当前汇编器的语法要求。例如，AT&T语法要求源在前，目的在后，而...

1、编译x264的时候老是不通过，用mingw编译最新的x264，./configure 时出现“No working C compiler found”, 原因:找不到c编译器。 解决办法：首先请确认你的已经正确安装c编译器，其次MinGW\msys\1.0\etc目下的fstab文件，如果不存在fstab，请复制一份fstab.sample，然后改名为：fstab，再修改其内容为：C:/m
