如何制作“灯"?带有语言支持等的GCC版本是否已修剪? [英] How to make a "light" build of GCC with language supports etc. pruned?

问题描述

基本上，我想仅支持C/C ++来简化GCC的构建.可以轻松做到这一点吗?还是需要对源代码进行手动修改?

Basically I would like to make a light build of GCC with only C/C++ support. Can this be done easily or does it require manual tinkering with source?

推荐答案

安装GCC 和配置

-enable-languages = lang1，lang2，...
指定仅应构建编译器及其运行时库的特定子集.有关langN的有效值的列表，您可以在GCC源代码树的gcc目录中发出以下命令:

--enable-languages=lang1,lang2,...
Specify that only a particular subset of compilers and their runtime libraries should be built. For a list of valid values for langN you can issue the following command in the gcc directory of your GCC source tree:

         grep language= */config-lang.in

当前，您可以使用以下任意一种:all，ada，c，c ++，fortran，go，java，objc，obj-c ++.构建Ada编译器有特殊要求，请参见下文.如果不传递此标志，或不指定所有选项，则将配置gcc子树中所有可用的默认语言.Ada，Go和Objective-C ++不是默认语言.其余的都是.

Currently, you can use any of the following: all, ada, c, c++, fortran, go, java, objc, obj-c++. Building the Ada compiler has special requirements, see below. If you do not pass this flag, or specify the option all, then all default languages available in the gcc sub-tree will be configured. Ada, Go and Objective-C++ are not default languages; the rest are.

因此，根据您的情况使用:

So, for your case using:

../gcc/configure --enable-languages=c,c++

当然，除了其他所需的选项之外，就足够了.

should be sufficient, besides other needed options, of course.

请注意，在调用"make"时重新定义语言已经不起作用了！
