Unable to build echoserver example
Opened this issue · 1 comments
Deleted user commented
I setup an ubuntu 18.04 docker environment with gcc 8 and installed the required dependencies without any troubles. Wangle will also build successfully
When I try to compile the echoserver example it fails with an openssl error I haven't been able to track down
g++ -o server EchoServer.cpp -lwangle -Wl,-Bdynamic -lfolly -lgflags -lglog -lpthread -ldl -lboost_context -lboost_program_options -lboost_thread -lboost_filesystem -lboost_system -lboost_regex -lboost_chrono -lssl -lcrypto -llzma -lz -lsnappy -llz4 -liberty -levent -ldouble-conversion -lfizz -lsodium --verbose
Using built-in specs.

figured it out, it was the order of the linked libraries that was the problem. This works:
