参考脚本
https://github.com/OnionBrowser/OnionBrowser/blob/master/build-libevent.sh
生成的库在dependencies路径下。
问题1
COULD NOT VERIFY PACKAGE SIGNATURE...
解决方案：
修改脚本中的 VERIFYGPG=false
问题2
configure: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details
解决方案：
去掉模拟器架构，修改ARCHS="armv7 arm64"
问题3
configure: error: openssl is a must but can not be found. You should add the directory containing
openssl.pc' to thePKG_CONFIG_PATH' environment variable, or setCFLAGS' andLDFLAGS' directly for openssl, or use `--disable-openssl' to disable support for openssl encryption
解决方案：
脚本中加入--disable-openssl，即修改为
./configure --disable-shared --enable-static --disable-debug-mode --disable-openssl ${EXTRA_CONFIG} \
修改后的完整脚本参考如下
