[go-nuts] Re: Cross-Compile Windows 10 -> FreeBSD

Not hopeless, just hard. You need a cross-C-compiler, and use that. It's easier to compile on native en. But you can try github.com/karalabe/xgo if you have Docker. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group. To unsubscribe from this group

Re: [go-nuts] how to prevent go1.13 go directive being written in an go directive-free go.mod?

Having that and exactly what it means in the go help modules output would probably be the best outcome. Currently it's not mentioned in that output for the current release (1.12.6) and the meaning/implication of "expected [Go] language version" is not defined in tip's version (f2a4c13). Dan On

[go-nuts] Re: Cross-Compile Windows 10 -> FreeBSD

To reply to myself, I just found this comment under ADDENDUM: "Cgo has issues when cross compiling. If you depend on cgo then you’re probably going to be better off building on the native platforms. The go tool will disable cgo support by default. To explicitly enable cgo, set CGO_ENABLED=1."

Newb here. I'm in over my head. Using a Win10/amd64 PowerShell with Go v1.12.6. Trying to cross-compile to FreeBSD/amd64. go env = GOARCH=amd64 & GOOS=freebsd. Source includes calls to SQLite3. Compiles without errors. Resulting binary fails on FreeBSD with: "Can't connect to the SQLite DB

Re: [go-nuts] how to prevent go1.13 go directive being written in an go directive-free go.mod?

As far as I understand, it is not a minimum version of the language. Also, a key point that is easy to miss is that the language version is distinct from tooling version, and newer tooling versions will know how to compile older language versions. At least, that is my understanding, though I

https://golang.org/cmd/go/#hdr-The_go_mod_file documents the go directive as the "expected language version". It seems it would be better described there as the "minimum language version". On Tue, 11 Jun 2019, at 2:43 PM, Ian Lance Taylor wrote: > On Tue, Jun 11, 2019 at 6:40 AM Ian Lance

Re: [go-nuts] why need "assist garbage collection" at a GC cycle? (runtime Code)

Indeed. If you allocate data faster than the GC mark phase can find and mark it, it enlists the "mutator" (I.e., your program) to assist it in the GC. Roughly, allocations are now followed by some marking work, so the allocation rate doesn't outpace the marking rate. The solution is to lower
