Hi, Recently we found out that the .interp section starts to show up in ARM executables compiled with "-shared -static" and the gold linker from binutils 2.22. We tracked down the origin of the dynamic linker commands and they are always explicitly specified in config/arm/linux-elf.h. We tested the following simple patch to suppress the dynamic linker options for statically linked programs on Android's AOSP tree. Everything builds fine and the unneeded .interp section is gone. Thanks, -Ben == gcc/ChangeLog 2012-09-14 Ben Cheng <bccheng@google.com> * config/arm/linux-elf.h: Suppress the dynamic linker commands for statically linked programs.
