Empty deb

[mperham]

I'm trying to build a DEB for a really simple executable. Notice the .deb is 420 bytes, not many KB as I would expect. I am running on OSX 10.9.

Hi, thanks for the detailed report.

It looks like it hasn't found any go sources with a 'main' package, so the 'xc' task isn't even generating an executable. The .tar.gz looks pretty much empty aswell.

... Up to this point I haven't used goxc for compiling non-main packages, and I guess goxc should really be compiling a '.a' file for these packages. But, is that actually what you're trying to do? (I don't really know the value of a .deb containing a .a file, and I wouldn't know where the deb should install it either). Can you shed some light on what you're trying to achieve please?

Have I interpreted it right? What is inside inspeqtor.go? Is it meant to be a library as I guessed, or is it actually meant to be a 'main' package? What happens when you enter go run inspeqtor.go

Cheers

I'm new to Go and trying to figure out what I'm doing too. :-). Thanks for the pointer.

Got further, now go build is failing but runs fine when I run it manually:

Do I need to manually build imported packages?

Hi there Mike, that syslog package imports C codem and it's only possible
to cross-compile pure Go code. This is a limitation of the go compiler.
Please read up on this in Dave Cheney's article:
http://dave.cheney.net/2013/07/09/an-introduction-to-cross-compilation-with-go-1-1
Ideally goxc should detect this issue and print a warning message, but it
doesn't at this stage.

So, if you want to cross-compile, you'll need to remove the syslog package.
