Compilation issue

User reports:

I am trying to cross compile https://github.com/openziti/ziti-tunnel-sdk-c/ against openwrt toolchain provided by Teltonika RUT SDK https://wiki.teltonika-networks.com/view/Software_Development_Kit. We got the steps to cross-compile from ticket https://openziti.discourse.group/t/ziti-tunnel-sdk-c-cmake-install-failure/118 I was able to compile previously with older version of ziti tunnel (v.0.8.6) but now i need to use latest version (v0.16.2). Post compilation i am getting the following error.

[100%] Linking C executable ziti-edge-tunnel mips-openwrt-linux-gcc: warning: environment variable 'STAGING_DIR' not defined mips-openwrt-linux-gcc: warning: environment variable 'STAGING_DIR' not defined CMakeFiles/ziti-edge-tunnel.dir/netif_driver/linux/tun.c.o: In function run_command_va': /home/username/ziti-tunnel-sdk-c/programs/ziti-edge-tunnel/netif_driver/linux/tun.c:94: undefined reference toWEXITSTATUS' collect2: error: ld returned 1 exit status programs/ziti-edge-tunnel/CMakeFiles/ziti-edge-tunnel.dir/build.make:146: recipe for target 'programs/ziti-edge-tunnel/ziti-edge-tunnel' failed make[2]: [programs/ziti-edge-tunnel/ziti-edge-tunnel] Error 1 CMakeFiles/Makefile2:1793: recipe for target 'programs/ziti-edge-tunnel/CMakeFiles/ziti-edge-tunnel.dir/all' failed make[1]: [programs/ziti-edge-tunnel/CMakeFiles/ziti-edge-tunnel.dir/all] Error 2 Makefile:170: recipe for target 'all' failed make: *** [all] Error 2

Also could you tell me, what should be configured for STAGING_DIR. If it is effecting the outcome of the above cross-compile.

Hi Team, I could fix the above error by doing below steps Open ziti-tunnel-sdk-c/programs/ziti-edge-tunnel/netif_driver/linux/tun.c Add #included <sys/wait.h> execute "make clean" and "make" again.

But now thou the binary gets created, it isn't executing on openwrt env.

I need urgent help on it

Hello,

Thanks for sharing what you've done to fix the build! We will incorporate that into the next release.

Regarding the failure to start; there is a chance that the issue could be with the init.d script rather than the ziti-edge-tunnel binary. Could you please:

1. Share your /etc/init.d/ziti script here?
2. d\Does your init.d script capture the ziti-edge-tunnel output in a log file? If so could you share that log here? If not, could you run ziti-edge-tunnel directly and share the output here?

Thanks, -Shawn

Hi Shawn, I have used the init script which is mentioned here https://github.com/openziti/ziti-tunnel-sdk-c/blob/main/docs/openwrt/ziti.init. The content is copy paste of the same. Using this script i couldn't get where it creates a log file. Please share the path. Using this init script i use the command "/etc/init.d/ziti start" to start and "/etc/init.d/ziti stop" to stop the tunnel.

Regards, Sameer Sarkar

Hi Sameer.

Thanks for pointing me to the script that you are using. Apparently the script was not updated when the ziti-edge-tunnel command line options were changed recently. I think the offending line in the init script is this:

procd_append_param command -c ${idfile}

Could you edit the script so the line above uses -i instead of -c?

Thanks, -Shawn

[sameersarkar-tcl]

Hi Shawn, Thanks for suggesting the change. I was about to message back the same. When you suggested the idea of running the binary directly, then i realized about starting the tunnel in such way. And i observed that new binary requires -i option rather than -c.

I believe now you have to fix this change in https://github.com/openziti/ziti-tunnel-sdk-c/blob/main/docs/openwrt/ziti.init in github.

Thank you, Sameer Sarkar

Hi Shawn, Please close this ticket. Thanks Sameer Sarkar

Thanks Sameer! I'll get the changes that we discussed here into the next release!
