例とスタティックlibをrestbed

Question

こんにちは私は例と静的なlibとしてrestbedをコンパイルしたいが、私はリンカエラーがあります。

使用：Ubuntuの16.04のgcc-5.4私がやったこと

：

cd dependency/openssl 
./config 

*long text* 

Configured for linux-x86_64. 

*** Because of configuration changes, you MUST do the following before 
*** building: 

     make depend 

ので、私は依存作り、作りました。それはlibcrypto.aとlibssl.aを作った だから私はこの部分は大丈夫だと思いますか？

次

cd build 
cmake -DBUILD_TESTS=YES -DBUILD_EXAMPLES=YES -DBUILD_SSL=YES -DBUILD_SHARED=NO -DCMAKE_INSTALL_PREFIX=static ..

私は問題を解決する方法を知らないので、それはLIBSを検索します。

アップデート：私は今、それが動作

sudo apt-get install libssl-dev 
cmake -DBUILD_TESTS=YES -DBUILD_EXAMPLES=YES -DBUILD_SSL=YES -DCMAKE_INSTALL_PREFIX=static .. 

でSSLと暗号LIBSをインストールしたのですが、私はhttpsをサポートして例をコンパイルしたいとき、私はまだ-lsslと-lcryptoでそれをリンクする必要がありますが、それはありますおそらくSSLと暗号は共有ライブラリであるからです。

g++ -std=c++11 -I/home/jova/git/restbed/build/static/include https_service.cpp -L/home/jova/git/restbed/build/static/library -lrestbed -lssl -lcrypto -pthread 

どのように私は静的ライブラリrestbed.aにsslサポートを取得できますか？または、私はいつもSSLと暗号とリンクする必要がありますか？

私は混乱しています。このオプション-DBUILD_SSL = YES/NOは何をしますか？

Answer 1

問題はリンクの問題と思われます。 -ldlを追加してみてください。
