安卓下刚开始提示"curl_rule_01 declared as an array with a negative size" 修改头文件后 又提示下边这个 怎么解决 Build command failed.

看样子是没有正确的引入 zlib 库吧？

[70kg]

@stonexing 有解决吗

[stonexing]

解决了就是leenjewel说的问题 没有正确引入zlib 我用的Android studio 解决办法是在build,gradlw(Module:app)中 externalNativeBuild { cmake { cppFlags "" } } 添加-lz 为 externalNativeBuild { cmake { cppFlags "-lz" } }
