Re: [go-nuts] go build for mips

[ktye78]

This can be related to issue #18162
If you compile a normal go program for mips32 with the current compiler and 
run it on hardware without FPU, this is the error message you see.
The preferred solution is for the compiler to emmit soft float code. It has 
been implemented but did not make it into go-1.9.
As a work around, if you can recompile the kernel, you can add floating 
point emulation to the kernel.

Hi folks. I am trying to execute clean.bash but it is giving me an error 
like 

go: open /home/ak7/go1.8/src/runtime/internal/sys/zversion.go: no such file 
or directory

I am on a Linux-ubuntu desktop 16.04 with bash shell running go1.8.0.; 
On the other hand, make.bash does complete successfully and install go 
binaries into my GOROOT 

Could you suggest what is it that I am missing here?

Please show us precisely what you did.  Don't transcribe--that just
leads to confusion like the use of lower case when you meant upper
case.  Cut and paste from the terminal.

Please show us precisely what happened.  What was the exact and
complete output of running the program on the MIPS board?

Try running the program on the MIPS board using a debugger to find out
exactly what the illegal instruction was.

[go-nuts] Re: go get golang.org/x/tools asks for a go.googlesource.com password on osx??

[Jason E. Aten]

Nailed it:

It turns out there was a ~/.gitcookies file, referenced from ~/.gitconfig, 
that was messing up git.

The ~/.gitcookies file had a .googlesource.com cookie in it. I renamed the 
~/.gitcookies file, effectively deleting it, and now things work as 
expected.

It does work fine on linux, and on a different OSX 10.11.6 laptop with git 
2.8.4 (Apple Git-73), so it is definitely a configuration on the OSX 
10.12.5/git 2.11.0 (Apple Git-81) thing.

I'd heard osx Sierra 10.12.5 was bad but I had no idea it was this bad... 
can anyone reproduce (or not) on Sierra 10.12.5?

Re: [go-nuts] go build for mips

[lucasw]

I'm building on linux amd64 system and want to execute the go binary on 
mips arch.

Go1.8

The binary is successfully compiled, but when I execute it on my specific 
architecture (mips), I got an illegal instruction.

The file information I provided is about the go binary compiled.

It's a hello world in go --> https://gobyexample.com/hello-world

I was able to run helloworld for mips but I had to build an image based on 
eglibc (glibc), instead of uClibc (based on this tutorial: 
http://akagi201.org/post/golang-on-openwrt/) 
I would like to be able to run without changing the base image.

Harmen, I build it with capitals like you said (only typed with lowercase 
here).

Re: [go-nuts] go build for mips

[Nathan Kerr]

What system are you building on (OS and architecture)?

What version of Go are you using?

Is the result of running go build an illegal instruction?

What file did you provide information for?

What is in hello.go?

Re: [go-nuts] go build for mips

[lucasw]

I try to build a simple hello world with
cgo_enabled=1 goarch=mips goos=linux go build hello.go| Result: illegal 
instruction 

file information: ELF 32-bit MSB executable, MIPS, MIPS32 version 1 (SYSV), 
statically linked, not stripped

Also, tried to build with another compile (CC=/path/to/Compiler) instead 
the one go uses. Also illegal instruction 
on my router tp-linkwdr3500.

If anyone could give me a hint, I would be grateful.

Thanks,
Lucas.

github/gota does not look like a valid import path.

If you mean this:

jnml@mate1610-32:~$ echo $GOPATH
/home/jnml
jnml@mate1610-32:~$ rm -rf $GOPATH/src $GOPATH/pkg
jnml@mate1610-32:~$ go get -v github.com/kniren/gota
github.com/kniren/gota (download)
package github.com/kniren/gota: no buildable Go source files in
/home/jnml/src/github.com/kniren/gota
jnml@mate1610-32:~$

then the problem is that the import path does not refer to any package so
there are no transitive dependencies to download.

Try this:

github.com/gonum/matrix (download)
github.com/gonum/blas (download)
github.com/gonum/internal (download)
github.com/gonum/floats (download)
github.com/gonum/lapack (download)

Re: [go-nuts] Go get function improvements

[Vickey Rawat]

A very simple example is i downloaded a package from github say

GITHUB/GOTA

Now when i use go get github/gota

It installs the package in my src directory

But it doesn't download

Github/gonum

And github/gonum/plots

Too

On which gota package is depended...


That's what i expect it to do too...

Its vry common in languages like R and python. Golang should have it too.
Because it then becomes hard to keep track of packages required.

If I understand you correctly, that is how it works today.  So I
probably do not understand what you mean.  Can you give an example
showing what you do, what you expect to happen, and what happens
instead?  Thanks.

What caused the stack trace?  I would have expected to see something
at the start saying why it was generated, but I didn't.

At first glance it looks like you have a deadlock somewhere.  Is there
something reading from the channels?

[go-nuts] Go get function improvements

[vickey . coool]

Go get function should import packages exponentially.

Like the dependency of the package and the dependency of the dependent package 
should all be downloaded at once when we download the package.

It should check if the package exist if not download all of the stuff. Its vry 
common in languages like R and python. Golang should have it too. Because it 
then becomes hard to keep track of packages required.

[go-nuts] Goroutine error when running on load test.

I am getting the following error when my services are being load tested.
I am new to goroutines and may be missing something in my implementation.
My service on being hit is running 2 goroutines that call an http request. 
After both return , the response from both http requests is returned into a

What could be the possible reason of the following stack trace of error??

[go-nuts] go build for mips

Since go1.8 added support for mips32, why can't build a simple hello world 
for a mips architecture system?

I successfully build programs for arm architecture, but could not do the 
same for mips.
