在cygwin下编译uclinux的问题

fywtiger

我按照lumit4510_user_guide_1.4.pdf上面的操作，在操作到
make user_only的时候提示如下的错误

主要就是提示使用的浮点操作一个是硬件浮点一个是软件浮点，请大家给帮忙解决一下。

交叉编译器是从 lumit 网站上下载的么？

我开始使用的是从lumit下载的，但是这个文件在cygwin下安装后出现的文件不能够使用，which arm-elf-gcc后找不到位置，所以后来又下载的其它版本的，这个安装包在red hat9下没有问题，在cygwin下安装就不能够生成可以识别的arm-elf-gcc，不知道为什么。

还没有实验过在 cygwin 下编译 lumit4510 uclinux 的包，建议还是换 vmware 吧，那样学习起来更有效率，可以避免 cygwin 下许多莫名其妙的问题。

请问楼主的问题如何解决的？我在Vmware下编译make user_only时也出现类似问题：

解决了，请说下如何处理。
