uclinux的移植问题

[tianlangxing2002]

我现在有arm-elf-gcc等一个交叉编译环境,并在这个环境下面有uclinux的源码,我想进行裁减,但是运行make xconfig后只能选择cpu厂商.lib库文件类型,和linux内核类型,我想裁减内核,胆识其他选择煤烟出现,请问是为什么??

你选择后就是裁减啊，编译通过后再挂装就是自己的内核了

不知道
楼主给点分

The fact that an option is available in your architecture's configuration menu does not automatically mean that this feature is supported for your target. Indeed, the configuration menus may allow you to enable many kernel features that have never been tested for your target. There is no VGA console, for instance, on ARM systems. The configuration menu of the kernel, however, will allow you to enable support for the VGA console. In this case, the actual kernel build will fail if you enable support for this option. In other cases, the selected feature, or even the entire kernel, will not be functional. To avoid these types of problems, make sure the options you choose are supported for your target. Most of the time, as in the case of the VGA console, it is a matter of common sense. When the choice doesn't seem as evident, visiting the appropriate project web site, such as the ones provided in Chapter 3, will help you determine whether the feature is supported for your target.
