如何用Eclipse编译32位 [英] How to compile for 32bit with Eclipse

问题描述

我目前在我的64位Ubuntu电脑上用c ++写一个小程序。默认情况下eclipse编译64位架构的程序。因为我想在我的服务器上使用我的小程序，仍然是32位，我需要能够编译我的程序为32位。我怎么能在eclipse中这样做？我已经花了一段时间的设置，但没有什么工作...

I'm currently writing a little program in c++ on my 64bit Ubuntu Pc. By default eclipse compiles the program for a 64bit architecture. Since I want to use my little program on my server which is still 32bit, I need to be able to compile my program for 32bit. How could can I do that in eclipse? I've been fiddling for a while with the settings but nothing worked...

推荐答案

我自己找到答案，经过大量的搜索和尝试。这是一个解决方案，如果你碰巧有同样的问题。
为此，必须安装以下软件包：

I found the answer myself, after lots of searching and trying things out. This is a solution that works if you happen to have the same problem. For this to work the following packages have to be installed:

• gcc / g ++ with multilib

• gcc/g++ with multilib

ia32-libs

ia32-libs

，然后选择属性。
转到C / C ++ Build并选择settings。在GCC / G ++编译器下，将-m32添加到命令字段（该字段现在应该为g ++ -m32）。
对GCC / G ++链接器执行相同操作。

Then right click on your project, and select "properties". Go to "C/C++ Build" and choose "settings". Under "GCC/G++ Compiler" add "-m32" to the command field (the field should now say "g++ -m32"). Do the same for "GCC/G++ Linker".

现在你已经添加了标志，这应该被编译为32位。
我使用的是Eclipse Galileo，因为你的界面看起来不一样。
我只添加了-m32标志只在发布配置文件下，所以我的调试构建仍然是64位。

Now that you have added the flag, this should be compiled for 32bit. I'm using Eclipse Galileo, for the case that your interface looks different. I only added the "-m32" flag only under the "Release" profile, so my "Debug" builds are still 64bit.
