静态可执行编译错误：未定义引用

Question

I am trying to compile a simple "hello world" program using a complete and stable GCC 4.4.0. Every thing is OK when I try to compile a dynamic executable but when I try to compile the static executable one, I get error "undefined reference to printf". It's the same in every program I try to compile in static mode. It can not recognize libc functions. Even with " -nostdlib " or " -lc " it's the same! Also " -L ${LD_LIBRARY_PATH} " does not fix it.

./ccL10382.o: In function `main':
test.c:(.text+0x4): undefined reference to `printf'
collect2: ld returned 1 exit status

What should I do?

Answer 1

At the first, look into libc.a. Looks like it should be in /system/android-gcc-4.4.0/sysroot/usr/lib/. So you need to execute:

nm /system/android-gcc-4.4.0/sysroot/usr/lib/libc.a | grep printf

If printf is present, you have a problem with link parameters. It can be verified by adding flag -v to gcc command line. Check output carefully to know what the libc links exactly.
