Compiling Errors

[vkumma002c]

Dear Philip,

I am trying to create a "influx-mysql" daemon using the this github repo. I have installed all dependencies such as qt5, snappy, Nim and nimble on centos 7 server.

When i tried to compile using the below instructions, i am getting the compile error as below.

Instructions followed:

nimble cpp --out:bin/influx_mysql influx_mysql/src/influx_mysql # 4

Compile time error:

[root@grafana nimble]# src/nimble cpp --out:bin/influx_mysql /usr/local/influx-mysql/influx_mysql/src/influx_mysql.nim # 4

Can you kindly help me to fix this error and proceed further.

Looks like you're running the compilation steps from outside of your cloned Git repository. The compilation steps must be run from the root of your influx-mysql Git working directory.

So in this instance, try cd'ing to /usr/local/influx-mysql and rerunning steps 1-5. Let me know if that works.

[vkumma002c]

Thanks Philip for your reply.

As suggested, I ran the steps1-2 from /usr/local/influx-mysql but the step2 has failed with below error though nimble was already installed.

[root@grafana influx-mysql]# nimble install -d # 2

Can you please suggest on this.

[philip-wernersbach]

What is in ~/.nimble/bin?

[vkumma002c]

Hi Philip, There is nothing in ~/.nimble/bin for now.

[philip-wernersbach]

It looks like you compiled nimble but forgot to install it. cd to /usr/local/nimble and run src/nimble install, then add ~/.nimble/bin to your PATH. As far as I'm aware, the nimble binary is supposed to be located at ~/.nimble/bin/nimble.

[vkumma002c]

Thanks Philip for your continuous support. I have re-installed the nimble and can see the binary file now. I ran the steps1-5 again but got the below error at step4.

[philip-wernersbach]

Looks like Nimble 0.8.* changed the "cpp" command slightly. Try specifying "influx_mysql.nim" instead of "influx_mysql/src/influx_mysql".

it starts compiling but never finished in my case , looks like it waiting on something

I'm having the same behavior. When running strace, It seems a problem after influx_line_protocol_to_sql.nim:

Then is just keep repeating the last line <wait4...>

Any ideas???
