Kitaplık nasıl kaynak kodu ile derlenir?Kitaplık NDK araçlarıyla kaynak kodu nasıl derlenir?
Android ndk ile yerel kitaplığı geliştiriyorum. Bazen kilitlenme iletileri logcat'ten aldım.

2e11c adresindeki gerçek kaynak kodunu bulmak bir sorundur? Ben google bazı çözümler aramak, birileri söyledi:
arm-eabi-objdump -S my_library.so
Ama çıkış metninde hiçbir kaynak kodu, orada sadece montaj kodu. Ben ndk5r örnek merhaba-jni projesini kullanın:
qty:jni qrtt1$ arm-eabi-objdump -S ../libs/armeabi/libhello-jni.so
../libs/armeabi/libhello-jni.so: file format elf32-littlearm

o -S seçeneği ile kaynak göstermek mümkün mü?

Denedim, ama sorun yok gibi görünüyor. /Users/qrtt1/app/android-ndk-r5b/samples/hello-jni/libs/armeabi/libhello-jni.so: ELF 32 bit LSB paylaşılan nesne, ARM, sürüm 1 (SYSV), dinamik olarak bağlantılı, soyulmuş. ps. Ben android-ndk-r5b kullanıyorum – qrtt1
Hmm, benim durumumda, obj/local/armeabi/libhello-jni.so her zaman 'soyulmuş' değil. obj/local/armeabi altında libs/armeabi altında değil. –
