如何解决在64位ubuntu上编译32位应用程序
我正在尝试构建NASA cFS版本6.5，该版本在运行Ubuntu的64位Jetson TX2上使用32位应用程序。
我遇到错误"gcc: error: unrecognized command line option -m32"。
我尝试安装gcc-multilib，但得到：
Package gcc-multilib is not available,but is referred to by another package. This may mean that the package is missing,has been obsoleted,or is only available from another source
我尝试使用apt search gcc-multilib寻找其他软件包，并安装了：
gcc-multilib-arm-linux-gnueabi
gcc-multilib-arm-linux-gnueabihf
gcc-multilib-x86-64-linux-gnu
gcc-multilib-x86-64-linux-gnux32
我知道有些可能不需要安装，但是我到处寻找解决方案，但是找不到任何解决方法。
我尝试取消注释sources.list中的所有行，运行sudo apt-get update，然后尝试安装，但仍然没有成功。
有帮助吗？
编辑：
好的，所以我从具有cmake的文件中删除了-m32选项，并尝试进行编译，但出现了很多错误，从typedef错误到missing;和其他，因为它们可能超过100个错误，所以不会列出所有错误，但是我得到的第一个错误是：
/home/deployer/CFS-101.initial/osal/src/os/inc/common_types.h:285:5: error: #error undefined processor
所以我去了common_types.h，它包含了以下内容：

我尝试检查是否有stdint.h和stddef.h，结果是，但是我不知道为什么 HAVE_STDINT 没有定义。另外，没有情况可以检查 aarch64 这是我的机器，所以我更改了
#if defined(_HAVE_STDINT_)
到
#if defined(_HAVE_STDINT_) || defined(__arch64__)
我尝试编译，并且它编译了大多数工具，但随后出现此错误：
Source file 'to_config.o' contains objects of class type 'ELFCLASS64 (2)' which is unsupported by this utility
我猜想是因为我删除了elf2cfetbl工具的-m32标志。
有帮助吗？
