ld：找不到用於-lcrypto的庫

Question

我正在嘗試運行http://iphonedevwiki.net/index.php/Theos/Setup教程，但停留在此步驟上：

 ./make.sh 
+ xcrun -sdk macosx g++ -mmacosx-version-min=10.4 -arch i386 -arch x86_64 -I. -I/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS11.4.sdk/usr/include/libxml2 -Ilibplist/include -Ilibplist/libcnary/include -c -std=c++11 -o out/ldid.o ldid.cpp

ld: library not found for -lcrypto
clang: error: linker command failed with exit code 1 (use -v to see invocation)

能否請你幫忙？

Answer 1

1. 檢查系統上是否安裝了-lcrypto （在Linux系統上，您可以嘗試調用ldconfig -p | grep libcrypto ，但是如果您使用的是macOS，請嘗試查找等效項）。
2. 如果該庫位於某個特定位置，請確保您的g ++調用包含正確的路徑，默認情況下g ++不會搜索該庫。
