Hi
lyang0@lyang0:~/downloads/uClibc-0.9.30.3/test$ make compile
TEST_LINK args/ arg_test

我的系统上肯定有这些头文件，因为：
lyang0@lyang0:~/downloads/uClibc-0.9.30.3/test/args$ gcc arg_test.c -o xx
lyang0@lyang0:~/downloads/uClibc-0.9.30.3/test/args$ file xx
xx: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux
2.6.8, dynamically linked (uses shared libs), not stripped
有哪为仁兄，下载个uclibc试下看 谢谢先

Hi,
uclibc我编译过不下50遍，你若是真的想解决问题，就应该把
INCLUDE PATH搞清楚。
# echo "int main() {}" > test.c
# gcc -Wp,-v test.c
把输出结果贴上了。
如果是在不行，你可以试试buildroot，但实际上没必要，
你的错误消息一看就知道是环境配置不正确。

从这个结果来看，至少可以肯定你机器上的某一个gcc是没有问题的，应该是host的toolchain.
你在配置uclibc的时候有没有开启交叉编译选项？编译用的命令是
# make
还是
# make CROSS=xxx-linux-
如果你使用的是交叉编译方式的，用同样的参数确认一下gcc的include path.
如果你搞不清楚究竟用的哪个，可以用下面的命令看看到底在哪里出错了
# make UCLIBC_EXTRA_CFLAGS="-Wp,-v"

我试了好几台 机器都是这个效果 ubuntu redhat 上都试了,注意我是在test那个目录下make的
Lei
我目前还没有使用交叉编译，以后要用，先尝试的非交叉编译
lyang0@lyang0:~/downloads/uClibc-0.9.30.3/test$ make UCLIBC_EXTRA_CFLAGS="-Wp,-v"

兄弟你太强大了！为什吗不直接在topdir做
make test
而要直接跑到test里面去make?

说老实话，make test没做过几遍，但有编译通过的时候，需要修改工具连和
uclibc的测试代码。除非你确认问题是工具链带来的，那么必须调整工具链，如果
是测试代码本身，我一般选择睁一只眼闭一只眼。
