cross-compile mattn/go-sqlite3 --targets=linux/arm

[zeevikal]

Im trying to compile mattn/go-sqlite3 to linux/arm.
I run:
sudo docker run karalabe/xgo-latest github.com/mattn/go-sqlite3 --targets=linux/arm
I get:

what am I doing wrong? thanks

[mattn]

go-sqlite3 doesn't use swig (file extension .i). may be it is not an issue of go-sqlite3.

[zeevikal]

can you advise me please, what should I do?
I want to compile github.com/mattn/go-sqlite3 to Arm6.
thank you

[mattn]

Sorry, I don't have arm6 and not well to know karalabe/xgo-latest.

I just have a test and it's okay to use xgo build linux/arm. My go env is

@zeevikal Current master has no problem with cross-compile

To compile for ARM6 use:

GOARM=6 GOARCH=arm go build -a -v .

Verification:

gtimmert@Aeris:~/Projects/go/src/go-sqlite3$ GOARM=6 GOARCH=arm go build -a -v .

I ran into this problem on a separate project and found a solution.

/tmp/tmp.izDbZRL94v/go-sqlite3.i:1: Error: Syntax error in input(1).

Here is what xgo generates

%module go-sqlite3
%{
#include "go-sqlite3.h"
%}
%pragma(java) jniclasscode=%{
static {
System.loadLibrary("go-sqlite3");
}
%}
%include "go-sqlite3.h"

The problem is the dash in %module go-sqlite3

The solution is to rename the project or add -out projectwithoutdash to xgo
