undefined reference `SRT_INVALID_SOCK' and `SRT_ERROR'

[batijo]

I am trying to run go get github.com/haivision/srtgo but getting this error:

# github.com/haivision/srtgo
/tmp/go-build815457234/b001/_cgo_main.o:/tmp/go-build/cgo-generated-wrappers:5: undefined reference to `SRT_INVALID_SOCK'

collect2: error: ld returned 1 exit status

Using SRT version: 1.4.1 and golang version: 1.14

Wow, I just had this too yesterday, exactly the same problem! Build system is Arch Linux.

1. Checked out srt v1.4.1 from Github, ./configure, make, make install. Files are in /usr/local/... Everything fine.
2. Go to new directory, create main.go and paste in example skeleton from the examples
3. Compile it with go build -work -v -x main.go (go1.14.1 linux/amd64, module exists). Result:

Later I also tried ./configure --use-static-libstdc++, as well as using pkg-config in the srtgo.go file - no change.

Using 1.4.0 was also unsuccessful.

Testing v1.3.4 does not seem to work as well. I think it's because srtgo uses SRTO_ENFORCEDENCRYPTION in srtsocketoptions.go, which was named SRTO_STRICTENC before v1.4.0 (commit https://github.com/Haivision/srt/commit/a82e0c34b0aadcb309d9e2f322b26f8f59bf827a).
