没导入ndk路径

wangha43 commented 3 years ago

修改app/CMakeLists.txt 去掉链接目录-L的第一个斜杠就可 set(CMAKE_CXX_FLAGS "${CMAKE_CXX_GLAGS} -L${CMAKE_SOURCE_DIR}/src/main/jniLibs/${ANDROID_ABI}")

yeocci commented 3 years ago

修改app/CMakeLists.txt文件如下，即可 @2014gaokao

2014gaokao commented 3 years ago

@yeocci 好哥哥，我在windows上改成这样后报如下错了 Execution failed for task ':app:externalNativeBuildDebug'.

Build command failed. Error while executing process D:\Android\sdk\cmake\3.6.4111459\bin\cmake.exe with arguments {--build E:\OpenGlCameraRender\app.cxx\cmake\debug\armeabi-v7a --target native-lib}

Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

但我今早在ubuntu上跑代码不用改都不报错，只不过进app就闪退了。然后又按照你的改了下也报了同样的错误。

yeocci commented 3 years ago

@2014gaokao 那你肯定没按我截图的做好，请再次检查set_target_properties最后一个参数的路径

闪退的问题可能是模型文件没有正确释放，模型文件在GlRenderWrapper下被释放并初始化，修改释放路径即可。
