I'm on windows7 x86_64. Using head of master branch.

What is GOARCH set to?

[ianlancetaylor]

E.g., go env GOARCH

[minux]

are you trying to build 32-bit windows program with a 64-bit-only mingw gcc?

@ianlancetaylor

set GOARCH=amd64
set GOBIN=
set GOEXE=.exe
set GOHOSTARCH=amd64
set GOHOSTOS=windows
set GOOS=windows
set GOPATH=c:/dev/go
set GORACE=
set GOROOT=c:\go
set GOTOOLDIR=c:\go\pkg\tool\windows_amd64
set GO15VENDOREXPERIMENT=
set CC=gcc
set GOGCCFLAGS=-m64 -mthreads -fmessage-length=0
set CXX=g++
set CGO_ENABLED=1

@minux
no. just building x86_64 app. if not link to go-sqlite3, it doesn't occur.

@mattn You are somehow linking against a version of go-sqlite built using GOARCH=386, which fails because you are using GOARCH=amd64. This normally shouldn't happen, as the different GOARCH value should store the package in a different location. Can you run go clean go-sqlite3 and then show us the output of go install -x go-sqlite3. Perhaps that will suggest something.

Ah, I figure out. I put syso file in the directory. It contains windows resource objects.
Sorry.
