netty-tcnative: java.lang.UnsatisfiedLinkError: no netty_tcnative_osx_x86_64 in java.library.path

hi When I add netty-tcnative-boringssl-static 2.0.7.Final in the pom file, and run my program, the console shows that:

java.lang.UnsatisfiedLinkError: no netty_tcnative_osx_x86_64 in java.library.path at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1867) at java.lang.Runtime.loadLibrary0(Runtime.java:870) at java.lang.System.loadLibrary(System.java:1122) at io.netty.util.internal.NativeLibraryUtil.loadLibrary(NativeLibraryUtil.java:38) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at io.netty.util.internal.NativeLibraryLoader$1.run(NativeLibraryLoader.java:229) at java.security.AccessController.doPrivileged(Native Method) at io.netty.util.internal.NativeLibraryLoader.loadLibraryByHelper(NativeLibraryLoader.java:221) at io.netty.util.internal.NativeLibraryLoader.loadLibrary(NativeLibraryLoader.java:207) at io.netty.util.internal.NativeLibraryLoader.load(NativeLibraryLoader.java:118) at io.netty.util.internal.NativeLibraryLoader.loadFirstAvailable(NativeLibraryLoader.java:82) at io.netty.handler.ssl.OpenSsl.loadTcNative(OpenSsl.java:419) at io.netty.handler.ssl.OpenSsl.<clinit>(OpenSsl.java:89) at io.netty.handler.ssl.SslContext.defaultProvider(SslContext.java:118) at io.netty.handler.ssl.SslContext.defaultServerProvider(SslContext.java:105) at io.netty.handler.ssl.SslContext.newServerContextInternal(SslContext.java:407) at io.netty.handler.ssl.SslContextBuilder.build(SslContextBuilder.java:441) at com.yunanbao.yunxiazi.proxy.servers.h5login.H5loginServer.run(H5loginServer.java:55) at com.yunanbao.yunxiazi.proxy.servers.h5login.H5loginServer.main(H5loginServer.java:88) 02-28 18:39:13.648 [main] DEBUG i.n.u.internal.NativeLibraryLoader [debug] [86] - netty_tcnative_osx_x86_64 cannot be loaded from java.libary.path, now trying export to -Dio.netty.native.workdir: /var/folders/cg/8__zm_7x70bdzbpyv_sf8z3m0000gn/T

@xinln Be sure to read all the log output … after the error you mentioned, do you see a line a little bit later in the log output that says Successfully loaded the library?

In the past, when I’ve had problems starting one of my apps that used netty, the error above was not the cause … the errors in the logs are easy to misinterpret. I’m not saying the same is true for you, but it might be 😉

(Seems like it might be more appropriate to have those in a TRACE log rather than DEBUG …)

I totally second that!

Ah … there are two stack traces in the logs – one preceded by

Unable to load the library 'netty_tcnative_osx_x86_64', trying other loading mechanism.

and the other preceded by

netty_tcnative_osx_x86_64 cannot be loaded from java.libary.path, now trying export to -Dio.netty.native.workdir ...

However, after those, I do see a successful load:

Successfully loaded the library /.../libnetty_tcnative_osx_x86_646414635283876674468.dylib

(Seems like it might be more appropriate to have those in a TRACE log rather than DEBUG …)

Not reopening ticket …
