Question

我从源代码构建了工件netty-tcnative-openssl-static-2.0.20.Final-linux-x86_64.jar。但是我注意到libnetty_tcnative.so是动态链接到openssl的，而不是静态链接的：

    [root@omega 2018-12-14--00-24-20 sb are you NRUSSEL? #]ldd META-INF/native/libnetty_tcnative.so

    libselinux.so.1 => /lib64/libselinux.so.1 (0x00007febf611b000)

这是正确的还是我的构建过程有问题？

是的，不知道您在做什么，但我只是使用netty-tcnative的当前主分支进行了尝试，并且可以正常工作：

./mvnw -pl openssl-static clean package

完成此操作后，您将看到所有预期的结果：

[root@d7724df14184 code]# ldd openssl-static/target/native-lib-only/META-INF/native/linux64/libnetty_tcnative.so
ldd: warning: you do not have execution permission for `openssl-static/target/native-lib-only/META-INF/native/linux64/libnetty_tcnative.so'
    linux-vdso.so.1 =>  (0x00007ffcbadb5000)
    librt.so.1 => /lib64/librt.so.1 (0x00007faccd3b1000)
    libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00007faccd17a000)
    libpthread.so.0 => /lib64/libpthread.so.0 (0x00007facccf5d000)
    libdl.so.2 => /lib64/libdl.so.2 (0x00007facccd59000)
    libc.so.6 => /lib64/libc.so.6 (0x00007faccc9c5000)
    /lib64/ld-linux-x86-64.so.2 (0x00007faccdae9000)
    libfreebl3.so => /lib64/libfreebl3.so (0x00007faccc7c2000)

例如，您可以将docker-compose文件用于centos，以确保您具有正确的env环境设置：

netty-tcnative git:(master) docker-compose -f docker/docker-compose.centos.yaml -f docker/docker-compose.centos-6.18.yaml run shell

jar netty-tcnative-openssl-static似乎已动态链接到计算机上的OpenSsl库，这是否正确？
