前几天在64位linux下开发跨平台的代码,包括32位和64位的版本都需要编译,在给g++加上-m32开关之后,g++报了一个错误:
gnu/stubs-32.h: No such file or directory compilation terminated. make: ***
在网上翻了一圈,情况就是64位linux缺省只安装了64位的头文件和Lib版本,需要增加32位的版本库,网上提到的安装方法一般是CentOs, Ubuntu之类的发行版,我用的是OpenSuse,最后在老外的网页上找到了一个比较全面的各个版本的安装说明:
You need 32bit embedded GNU C Library. This incldes development Libraries, header files, contains the symlinks, headers, and object files needed to compile and link programs which use the standard C library.
Fix for Debian Linux
Type the following command:$ sudo apt-get install libc6-dev
Fix for Ubuntu Linux
Type the following command:$ sudo apt-get install libc6-dev-i386
Fix for OpenSUSE / Novell Suse Linux (SLES)
Type the following command:# zypper in glibc-devel-32bit
Fix for RHEL / Fedora / CentOS / Scientific Linux
Type the following command:# yum install glibc-devel.i686
安装了头文件,还要注意安装库文件,方法同上,包括以下库:
gcc-32bit gcc7-32bit libstdc++6-gcc7-32bit libstdc++6-gcc7-locale libstdc++6-locale
