freethedsp's Issues

Can't compile

Hello.
I try to compile freethedsp.c with './clang -shared freethedsp.c -o freethedsp.so'.
Therefor I use clang with NDK-14 (also tryed 16).
I used "python make_standalone_toolchain.py --arch arm --api 24 --install-dir tmp" for generating the Clang toolchain.
But when trying to compile I get following error:

freethedsp.c:70:5: error: conflicting types for 'ioctl' int ioctl(int fd, unsigned long request, void *arg) { ^ ./../sysroot/usr/include/unistd.h:145:12: note: previous declaration is here extern int ioctl(int, int, ...); ^ freethedsp.c:91:17: warning: implicit declaration of function 'open' is invalid in C99 [-Wimplicit-function-declaration] int ionfd = open("/dev/ion", O_RDONLY); ^ freethedsp.c:91:34: error: use of undeclared identifier 'O_RDONLY' int ionfd = open("/dev/ion", O_RDONLY); ^ 1 warning and 2 errors generated.
Can anybody help me how to fix?

How may I determine patching parameter?

I compiled the .so file successfully. However that doesn't seem work. I think maybe the wrong parameter for patching the fastrpc_shell_0. Would you please tell me how to determine patching parameter? Thanks~~
