compilation of app for i386 arch "undefined: SQLiteConn"

[avecost]

no problem compiling the app for 64-bit arch, but when i set GOARCH=386 running go build this error is reported:

sqlite3_go18.go:18:10: undefined: SQLiteConn

[mattn]

You need to install cross-C-compiler for 386.

Hello Mattn,

I have already install GCC v7.2.0, still encountering the same error.

Maybe it would help if I mention I'm using Windows 10 64-bit

Thanks

[mattn]

please show me your go env?

Im sorry i uploaded an image.. i dont know how to paste a formatted text

[mattn]

try set CGO_ENABLED=1

github.com/mattn/go-sqlite3

../../go/src/github.com/mattn/go-sqlite3/sqlite3_go18.go:18:10: undefined: SQLiteConn

WIth CGO_ENABLED=1 I get:

# runtime/cgo

As I mentioned above, you need to install 386 compiler. 2017/11/20 午前6:23 "Eliezer Croitoru" <[email protected]>:

@mattn I am using Debian\Ubutnu , can you give me a hint on what might be the right package for this?
I have seen these docker containers:
https://github.com/dockcross/dockcross

But yet to understand how to use them.

[mattn]

sudo apt install gcc-mingw-w64-i686

and please point $CC to the compiler.

[avecost]

compiling on windows 10 64-bit for my app to run on 386:

with CGO_ENABLED=1

encountered "skipping incompatible.." errors

this is using mingw-w64 compiler

[mattn]

there are two compilers w64 and i686. you need to install i686 version.

[avecost]

Thank you for your patience and great help @mattn upon checking my BIOS Virtualization is not enabled. Upon enabling it the compilation works perfectly.

[mattn]

good to hear. 👍

I am on windows and build mattn/go-sqlite3 for linux
If set CGO_ENABLED=0 I have error

sqlite3_go18.go:18:10: undefined: SQLiteConn

If set CGO_ENABLED=1 I have error

What happen with me?

[mattn]

go-sqlite3 is cgo package. CGO_ENABLED=1 is required.
