MacOS 10.15.2
tinygo version 0.11.0 darwin/amd64 (using go version go1.13.6)

I am trying to compile rqlite to wasm, but rqlite has a C dependency (sqlite). I know tinygo has some cgo support, but I am not sure what to make of the errors:

$ CC=gcc CPATH="/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/" tinygo build -o wasm.wasm -target wasm ./rqlited/main.go

There are multiple things that are not yet implemented in TinyGo to get go-sqlite3 to compile. I'm aware of the following:

  • Build constraints in the #cgo line (as the error you reported indicates). This is for a line like the following:

    #cgo linux,!android CFLAGS: -DHAVE_PREAD64=1 -DHAVE_PWRITE64=1

  • Using a libc on WebAssembly, probably wasi-libc.

  • You probably haven't seen it yet, but including database/sql will result in several compile errors:

Take a look at #845, which should fix the "unsupported architecture" error.

The CPATH and CC environment variables should not be needed here. IIRC both are ignored.
