4 years ago I don't have a solution for this but the platform I'm on does support 32-bit binaries so I was able to install https://golang.org/dl/go1.14.6.linux-armv6l.tar.gz which is 32-bit which reports as:
go1.14.6 linux/arm and will build go-sqlite3 successfully.

4 years ago @clach04 Please provide the output from running go version and go env on the machine in question using the original Go installation that gave you that "unexpected: 4-byte pointer type - *char" error message. Also, please confirm that you have a 64-bit C compiler on the machine (that is, a C compiler that produces 64-bit executables).

I think this maybe it, it looks like gcc on this machine is 32-bit, and the two other compilers that support arm64 (gcc-6-arm-linux-gnueabihf and gcc-6-arm-linux-gnueabi) don't appear to be install-able on this machine.

gcc version 6.3.0 20170516 (Debian 6.3.0-18+deb9u1)I can build 64-bit Go apps, it looks like the go-sqlite binding requires the C headers/code and its not obvious there is a problem until hitting backup.go:29 - presumably due to the previous C compiler step that generated 32-bit output.
I suspect this can be closed. Is there any way to get the Go compiler emit the C compiler call(s) its making under the covers?

Yes, it should do that if you pass the -x flag to go build.
Also, I cannot speak for your version of gcc specifically, but usually the -m64 flag tells it to produce 64-bit executables. So try running CC="gcc -m64" go build and see if that fixes anything.

4 years ago -m64 was my first (failed) attempt before then trying to install more compiler options :)
Thanks for the flag info, ended up with:
go build -x -a 2> build_log.logI'm firmly convinced this is a lack of 64-bit C-compiler issue on my system.
Thanks again, closing.

The go version I have is:
go version go1.14.6 linux/arm64
Build fails:
machine info:
I'm not familiar with go, so I've no idea how to debug this :-( (I'm trying to build something else that depends on this and this appears to be the only stumbling block)
