What version of wasmd? v0.14.0?

Also, are you using the M1 silicon (arm64)?

Also, are you using the M1 silicon (arm64)?

@alpe I know you have a mac. Can you reproduce?

yes i can

my environment

OS: mackOS Big Sur 11.1
Go：go version go1.15.7 darwin/amd64

I only did the following

1. clone code of master
   git clone https://github.com/CosmWasm/wasmd.git

2. Normal make

make

i got some golangci-lint run error, it seems the code can't access lint check

golangci-lint run
app/app_test.go:86:6: `setGenesis` is unused (deadcode)
func setGenesis(gapp *WasmApp) error {
     ^

			                ^

3. make install

as step 2 can't work, i see the Makefile and find make install, so i do it, it's work well.

4. cross compile for linux
   i just execute make build-linx, get the error bellow.

@biffyx try to use docker to build under macos, check this https://github.com/terra-project/core/blob/develop/Makefile#L82

@alpe I know you have a mac. Can you reproduce?

yes, I have the same error messages with make build-linux. I can look into it later this week.

I tried today to make it work with CGO_ENABLED=1 and cross compiler installed but failed. I think a better solution is to go with docker indeed.
Let's keep this issue open until a containerized solution is added or the build-linux target removed.

Same problem when I use CosmWasm dependency in my project and build with docker.

# github.com/CosmWasm/wasmvm/api
/go/pkg/mod/github.com/!cosm!wasm/[email protected]/api/mock_failure.go:15:27: undefined: GoAPI
/go/pkg/mod/github.com/!cosm!wasm/[email protected]/api/mocks.go:114:2: undefined: GasMeter
/go/pkg/mod/github.com/!cosm!wasm/[email protected]/api/mocks.go:115:20: undefined: Gas
The command '/bin/sh -c CGO_ENABLED=0 go build -o watcher ./cmd/watcher/main.go' returned a non-zero code: 2

Docker build with CGO_ENABLED=1 doesn't work either. When I build on linux, it works for me, but docker does not work and does not work on windows (gcc is a problem and tdm-gcc does not solve it).

[ethanfrey]

@Raumo0 there is no support for Windows. This is a long-term issue and blocked by an upstream dependency: CosmWasm/wasmvm#28

Are you building this repo or a fork? What commit are you building?

Please provide the OS, CPU arch (i686 or arm64), repo/commit you are building and the exact commands you run.

I only have a Linux machine, but other devs use OSX and can verify there. No backend devs is using Windows or WSL so hard to debug there - you can compile CosmWasm contracts on Windows, but not run a node there.

[webmaster128]

From searching the web it appears that combination cgo and cross-compilation seems to be immature at least.

Why do we even bother to provide cross-compilation as part of this repo's Makefile? Can't we ask users to run make build in a Linux docker container or Linux machine of their choice? I mean if cross compilation was possible, fine. But a dockerized solution is not cross-compilation but just a script collection that bascically says: cross compiletion not possible, please compile on Linux if you need a Linux build.

In the meantime the build-linux target was removed. There is only the .PHONY entry left.
