当我尝试使用其源代码在 Android 中构建增强库时,出现以下错误
release|armeabi-v7a : D:/Android/Sdk/ndk->bundle/toolchains/llvm/prebuilt/windows-x86_64/sysroot/usr/include/c++/v1\fstream:969:9: 版本|armeabi-v7a:错误:使用未声明的标识符"fseeko" release|armeabi-v7a : if (fseeko(__file_, __sp, SEEK_SET((
下面是我的CMake
externalNativeBuild {
cmake {

}
ndk {

fseeko64
在Android-24之前不可用。您必须提高minSdkVersion
或停止使用_FILE_OFFSET_BITS=64
。
