Error building go app : undefined: SQLiteConn

[Murf]

....\github.com\mattn\go-sqlite3\tracecallback_noimpl.go:7: undefined: SQLiteConn

OS: Windows 10 Pro 64
c++ compiler framework: MinGW64

[mattn]

can't reproduce this. what is different from general situation?

[Murf]

I have used the test code under "Quickstart" from https://github.com/go-gorp/gorp
I have go version go1.7.1 windows/amd64

I used "github.com/mattn/go-sqlite3" and it build and installed fine

Any other info you need Matt?

This is the error at the end of "go build test.go"
"#" github.com/mattn/go-sqlite3
....\github.com\mattn\go-sqlite3\tracecallback_noimpl.go:7: undefined: SQLiteConn

[mattn]

please try with go build -x on $GOPATH/github.com/mattn/go-sqlite3

[mattn]

What about go env ?

[Murf]

D:\Working\go\src\github.com\mattn\go-sqlite3>go env
set GOARCH=amd64
set GOBIN=
set GOEXE=.exe
set GOHOSTARCH=amd64
set GOHOSTOS=windows
set GOOS=windows

set CXX=g++
set CGO_ENABLED=1

[mattn]

I used "github.com/mattn/go-sqlite3" and it build and installed fine

But not? Is this an issue related on tests?

[Murf]

D:\Working\go\src\github.com>
D:\Working\go\src\github.com>rmdir /s mattn
mattn, Are you sure (Y/N)? y
D:\Working\go\src\github.com>go get github.com/mattn/go-sqlite3
D:\Working\go\src\github.com>

That is what I meant Matt, I did not get any errors when I installed it

[mattn]

Okay, then what is remaining issue?

[Murf]

Matt, I think if is a cross compiler issue
this works:
go build -v test.go

this does not:
D:\Working\go\src\local\syslog-connector-go>set GOARCH=amd64

D:\Working\go\src\local\syslog-connector-go>set GOOS=linux

D:\Working\go\src\local\syslog-connector-go>go build -v test.go

[Murf]

Further..
I used set CGO_ENABLED=1
and now have this problem (which seems to have progressed at least)

I think it is because cgo not supported for cross compilation in Go, I will move my dev environment to a linux container.
Thanks Matt, please close

[andrejvanderzee]

On Linux I am unable to compile without cgo. Is there any solution to this?

$ CGO_ENABLED=0 go build --ldflags '-extldflags "-static"' -ldflags '-s' -a -installsuffix cgo
# github.com/mattn/go-sqlite3
../../../../github.com/mattn/go-sqlite3/tracecallback_noimpl.go:7: undefined: SQLiteConn

[mattn]

go-sqlite3 require ENABLE_CGO=1

[nkumar15]

to be more clear CGO_ENABLED=1 is needed.

[codenoid]

using ubuntu 18.04

command :

CGO_ENABLED=1 GOOS=windows GOARCH=amd64 go build -o app.exe app.go

error :

gcc: error: unrecognized command line option ‘-mthreads’; did you mean ‘-pthread’?

[rittneje]

@codenoid You need to set CC to a valid Windows cross compiler. By default you are using the one for your host (Linux).

[codenoid]

@rittneje yea, just successfully compile my application in target host (windows)
