I have worked with two package named cube.go and main.go file.
in main file I have imported cube file.
but when I run the main file it not worked.please help me to fix this problem. enter image description here
Two files in a directory are in the same package, so you don't need to import cube, you code should be like this:
package main
import (
"fmt"
)
func main() {
var box Dims // Dims declared in this package in cube.go file
box.SetSize(2,4,6)
// other methods,etc
}
If you want to import cube, it's better to put cube.go file in another directory called cube or anything else and change the package name to package cube or whatever the directory name is.
And you should remove main function in cube.go file.

I built a directory src which contains the following:
src/
antlr/
basic_levex.go
basic_parse.go
basicparser_base_visitor.go
basicparser_visitor.go
example1.go
The antlr files look correct, and built the files called BasicLexer.g4 and BasicParser.g4 .
My example1.go file looks like:
package main
// example1.go
import (
"./antlr"
"fmt"
"github.com/antlr/antlr4/runtime/Go/antlr"
)
func main() {
// Setup the input
is := antlr.NewInputStream("1 + 2 * 3")
// Create the Lexer
lexer := antlr.NewBasicLexer(is)
// Read all tokens
for {
t := lexer.NextToken()
if t.GetTokenType() == antlr.TokenEOF {
break
}
fmt.Printf("%s (%q)\n",
lexer.SymbolicNames[t.GetTokenType()], t.GetText())
}
}
The error I get on compilation is
# command-line-arguments
./example1.go:8:2: antlr redeclared as imported package name
previous declaration at ./example1.go:6:2
./example1.go:16:11: undefined: "github.com/antlr/antlr4/runtime/Go/antlr".NewBasicLexer
I don't really know what is wrong. How to fix it so it doesn't happen in the future?
Let's look at both your problems one after an other
Duplicate Import
./example1.go:8:2: antlr redeclared as imported package name
previous declaration at ./example1.go:6:2
The error message is explaining pretty well what happened, including the lines:
On line 8 you try to import something with the same name that you already have imported on line 6.
Aside that, Go Does not support relative import, like Flimzy has pointed out in the comments.
To fix this remove the relative import on line 6.
Undefined function
./example1.go:16:11: undefined: "github.com/antlr/antlr4/runtime/Go/antlr".NewBasicLexer
The function that you are trying to use does not exist.
In this case it is actually called NewBaseLexer as opposed to NewBasicLexer as you can see in the code

I can't find the answer after much Googling.
I am making my first foray into sphinx, and I can't see how to include links to another page within my sphinx docs. It seems that the :doc directive should do the trick, but it isn't working.
For example, imagine I have the very simple tree:
./index.rst
./files/CPPFiles.rst
./files/PythonFiles.rst
The first one, index.rst as well as having a TOC wants a link to one of these subfiles in the "free" text, so my index.rst contains this:
My Docs
=======
This is a Python module but powered by a C++ back end.
Unless you're planning on extending this module you only need
to read :doc:`the Python docs<files/PythonFiles>`.
.. toctree::
:maxdepth: 2
:caption: Contents:
files/PythonFiles
files/CPPFiles
I've also tried with just
:doc`files/PythonFiles`
In both cases, the text within the :doc: appears as expected, but is not a link.
White space has meaning in reStructuredText.
:doc:`the Python docs<files/PythonFiles>`.
Should be:
:doc:`the Python docs <files/PythonFiles>`.

I’m trying to upload a custom CSV file.
Does anyone know what this error means?
Skip import row, is not valid value “” for field “type”
Better and easy way to import products please try the following way -
Add a product manually via Admin.
Export that product using Import/Export functionality of Magento.
Make your changes with the help of exported product data.
Add more product as per the Column of the CSV file.
Try to import and Enjoy!

I would like to be able to write my own version of a dependency walker tool (I think this is a good way to learn things).
However, I don't have the necessery knowledge to be able to know, given a PE file (dll/exe) - what are it's depenencies.
I would appreciate a reference to a place that can supply me this knowledge (tutorial / article / literature / etc..).
Thanks!
It's straight forward in principle (pseudo-code off the top of my head):
Create empty dependency list (list 1)
Create empty list of references yet to be looked at (list 2)
Add main module to list 2
repeat
Select first module in list 2
Open the PE file
Parse header to find import section
Enumerate import modules
for each module imported
if not already in list 1, Add it
if not already in list 2, Add it
Remove from list 2
until list 2 is empty.
Result in list 1.
To figure out how to actually parse the relevant parts of a PE, you can get the Portable Executable specification off of msdn.microsoft.com.
