cimg lib pour l'erreur de compilation android

Question

Je tente de compiler CImg pour android. Mais vous avez de telles erreurs lors de la compilation.

qui fait partie de la Application.mk `

APP_STL := gnustl_static 
NDK_TOOLCHAIN_VERSION=4.9 
APP_CPPFLAGS +=-std=c++11 
APP_ABI := armeabi armeabi-v7a 
APP_CPPFLAGS += -frtti 
APP_CPPFLAGS += -fexceptions 
APP_CPPFLAGS += -DANDROID 

APP_OPTIM := release 
LOCAL_ARM_MODE := thumb 

Je suis arrivé suite à des erreurs

Pourquoi? Comment le résoudre?

Answer 1

bien fait, j'ai résolu moi-même. Ce problème causé par le compilateur, qui seule ligne de code ne peut pas définir la variable trop. (Version NDK est R9d)

int a = 1, b = 2, c = 3, d =4, e = 5; 

tour ce code dans plusieurs lignes.

int a = 1; 
int b = 2; 
int c = 3; 
int d = 4; 
int e = 5; 

cela a résolu ma question.
