Build failure with C SDK

SDK Questions sdk-c

Hi, I’m trying to build ziti-sdk-c (standalone) but am facing a linker error. To build, I followed the instructions in BUILD.md.

I’m building on Arch Linux. I also tried building in a debian trixie docker container, and I got the same error.

Context: my eventual goal is to call the C SDK via Rust FFI. I figured I’d start by just building the C SDK.

Thanks in advance for any help.

Please share the complete build logs (via pastebin service).

If there is any extra verbosity I should enable, please just let me know. I’m not the most familiar with CMake.

this may be related to you using gcc-15 for your build

if you just want to build SDK and do not care about ziti-sdk internal tests you can turn off building tests using ziti_DEVELOPER_MODE=OFF on your cmake command:
cmake --preset=ci-linux-x64 -Dziti_DEVELOPER_MODE=OFF ..
