@Arion-Dsh 请问是否解决了,出现同样错误 go version go1.10.2 linux/amd64

We are looking into the issue, stay tuned

I have occurred the same errors, please check it. Thanks. @ChengOrangeJu

@Arion-Dsh @MuZiRuoYi @sppsun

When running make deploy-v8, it will install *.so files form nf/nvm/natve-lib to dir /usr/local/lib :

To check if make deploy-v8 is succeed, please check if there are libicui18n.so libicuuc.so files under /usr/local/lib.

If there is not, then check if there are these two files under nf/nvm/natve-lib of go-nebulas directory.

If there is no these file under nf/nvm/natve-lib , please pull the latest code of go-nebulas again. Then you can run make deploy-v8 again.

@yupnano Hello, I have try according to your advice, the libicui18n.so and libicuuc.so two files also exist in nf/nvm/natve-lib and /usr/local/lib dirs , but make build occurred the same error. My platform is centos 7, please check it. Many thanks.

@sppsun please try ldd /usr/local/lib/libnebulasv8.so to list the shared object dependencies. There might be some items "not found" , then try sudo ldconfig.

@Arion-Dsh @MuZiRuoYi Have you resolved this problem?

@yupnano Thank you. I have resolved. But your advice have some problems in my platform. My steps are: 1. create a file name like libv8.conf in /etc/ld.so.conf.d, and its content is /usr/local/lib/; 2. ldconfig; 3. make build.

@yupnano resolved too. I just clone the project and build again.

but I think the issue is when git pull the change will break symbolic link of those files.
