libEGL.so not found in android-ndk-r6 on mac os 10.7.3

[brucewuu]

I write a c library with opengl es 2.0 , and build with android-ndk-r6
on mac os 10.7, then I met libEGL.so not found , but when I tried with
android-ndk-r7b , there is another issue . I can build them into
test.so ,
but when I run my android application, it says no native function
implementation found , I checked the test.so , I could not find the
symbols of the functions I defined in the c source files , but I am
sure the package path is right , and I tried on ubuntu , there is no
such problem , and I also try to build my c library into static
library test.a , and I checked the symbols are defined in test.a ,
while not in test.so . it is very strange , i use the ar and ranlib
from android-ndk-r7b to package the library .
here is the error log when I build with r6 , and link the
project .

anyone knows why and tell me some solution , thanks very much .

I recommend setting up a standalone toolchain binary with a sysroot / API level that matches your needs (libEGL.so is only available since API level 9, iirc) instead of calling the binaries directly from $NDK/toolchains/...

See docs/STANDALONE-TOOLCHAIN.html for details.

Also,

"""ld: warning: cannot find entry symbol _start; defaulting to 00012fa0"""

means that you're likely trying to build an executable instead of a shared library.
