can't compile on mips

[umito]

[mips] Compile        : NativeSampler <= coffeecatch.c
jni/coffeecatch/coffeecatch.c:79:58: error: 'SIGSTKFLT' undeclared here (not in a function)
jni/coffeecatch/coffeecatch.c: In function 'coffeecatch_get_pc_from_ucontext':
jni/coffeecatch/coffeecatch.c:1011:2: error: #error "Architecture is unknown, please report me!"
make.exe: *** [obj/local/mips/objs/NativeSampler/coffeecatch/coffeecatch.o] Error 1

armeabi works perfectly, but when it comes to the mips part, it won't compile.
Using android-ndk-r9d-windows-x86_64

[umito]

Also, below android 2.2 (or possibly 2.3) sigaltstack is not available and causes loadLibrary to fail. I tested this on emulator and device. Is there a minimum Android version that is supported?

[xroche]

Normally 2.2 should be fine!

Can you test MIPS now ? Issue with "Architecture is unknown" should be fixed by ae35ddb

[umito]

It compiles perfectly now on MIPS and catches the error and provides a somewhat proper stacktrace.

I don't know if it is just the emulator, the native stacktrace is not very detailed here, it doesn't show the native method names. Is this is a limitation of MIPS or just the emulator?

Anyway thanks for the fix!

Unfortunately there is no simple way to get the function name directly.

However, you can easily get it using addr2line:

PATH_TO_ANDROID_SDK/toolchains/arm-linux-androideabi-4.7/prebuilt/linux-x86_64/bin/arm-linux-androideabi-addr2line -C -f -e libNativeSampler.so 0x35d0

(replace PATH_TO_ANDROID_SDK by correct path and use proper architecture, of course)

EDIT: with Android >= 4.1.1, you should get the function names (libcorkscrew is used by coffeecatch, if available)
