I download the toolchain stbgcc-4.8-1.0 for further testing. For android, I update the test here. https://github.com/xiaoyur347/issue/tree/master/mips-dlopen (1)mipsel-linux-gnu 4.8.4(compiled by Broadcom) mipsel-linux-gnu-gcc 4.8.4 binutils 2.24 (GNU ld (GNU Binutils) 2.24.0.20140801 Linaro 2014.08) libc 2.18-2013.10 It's not uclibc.
