cygwin下为mini2440编译 glibc

你门有谁在cygwin下为mini2440编译过glibc?
版本glibc2.7
port包也打了，没有用linuxthreads

$ CC=arm-linux-gcc ../glibc-2.7/configure --host=arm-linux --prefix="/usr"  --with-headers=${TARGET_PREFIX}/include
输出：

checking for .protected and .hidden assembler directive... yes
checking whether __attribute__((visibility())) is supported... no
configure: error: compiler support for visibility attribute is required

如何解决？

checking whether __attribute__((visibility())) is supported... no

arm-linux-gcc不支持__attribute__((visibility())) , 恐怕你得换一个高版本的gcc, 或者用低一点版本的glibc

我用的是arm-linux-gcc 4.3.3

换了4.3.1 输出;
running configure fragment for nptl/sysdeps/pthread
checking for forced unwind support... no
configure: error: forced unwind support is required
如何解决?

还是用crosstool吧,太闹心了。
