Where is runhaskell supposed to come from? It is not on my path, and when I run stack build runhaskell, I get Unknown package: runhaskell.
stack exec -- runhaskell --help sounds like the right tool, though I'm not sure what the best answer is if another tool expects it to be available unqualified.

I'm trying out Go for the first time. I was following these docs and wanted to run the go tour locally, but I haven't figured out how to get it to work.
Where is the tool "tour" supposed to be found?
I'm on OSX 10.11.3, and I installed Go via Homebrew
my Go entries in .zshrc
export GOPATH=$HOME/code/Go
export GOROOT=/usr/local/opt/go/libexec
export PATH=$PATH:$GOPATH/bin
export PATH=$PATH:$GOROOT/bin
tour is not installed by default with an installation of go. You need to go get it:
go get golang.org/x/tour/gotour
Docs: https://github.com/golang/tour/
I had a problem too. This's my solution, on OSX let try
gotour
With version go1.8.1 darwin/amd64
It works for me using go1.4, but not with go1.7. If you just run go tool, it gives you a list of known tools. They seem to have removed it from tools.
$ gvm use go1.7
$ go tool
addr2line
api
asm
cgo
compile
cover
dist
doc
fix
link
nm
objdump
pack
pprof
trace
vet
yacc
$ gym use go1.4
$ go tool

6g
6l

nm

tour # <--- here

yacc
Firstly, it is no longer gotour. And secondly, for the time being, the tour package is located at: golang.org/x/website/tour as opposed to what A Tour of Go Welcome Page says.
So, at least for now:
The correct way to get tour is:
go get golang.org/x/website/tour
Or,
go install golang.org/x/website/tour#latest
After which you can run the command in the terminal:
$ tour
2021/06/22 17:46:48 Serving content from /home/user/go/pkg/mod/golang.org/x/website/tour#v0.0.0-20210616181959-e0d934b43647

2021/06/22 17:46:52 accepting connection from: 127.0.0.1:33192
To find out where it has been installed, you can do which tour:
$ which tour
/home/user/go/bin//tour
reference
Because of changes in Go package management and introduction of modules, this has changed since the original question. Thus, for future reference (as this is the first Google result), if you have not configured GOPATH environment variable
go get golang.org/x/tour
$HOME/go/bin/tour
Note that the executable is called "tour" instead of "gotour".
Source (with full explanation of why and details): https://stephencharlesweiss.com/getting-going-with-golang/
I've got:
golang.org/x/tour/gotour has moved to golang.org/x/tour
So, this works for me:
go get golang.org/x/tour
then:
tour
When you install go, tour is not installed by default. You need to do a go get golang.org/x/tour/gotour. This downloads gotour in your workspace.
If you configured your PATH properly, gotour command from anywhere in the terminal will open up your browser, but if PATH is not configured properly, do a
$GOPATH/bin/gotour
This command can be used from anywhere in your command line and it opens tour in your default browser
http://whipperstacker.com/2015/09/27/how-to-run-the-go-tour-locally/
https://github.com/golang/tour/blob/master/README.md
Once gotour is installed, it’s executable like other executables are typically stored in the bin directory of your workspace. Inside the bin directory ./gotour will invoke or start gotour, elsewhere the gotour will need to be preceded by a path to where the executable is located. In other words $GOPATH/bin/gotour will invoke or start gotour when you are not inside the bin directory.
Ultimate Goal:
I'm trying to convert a binary plist file to an xml format so that I can put it in an array and grab values from it. What I'm finding via web search on this is that the command for Linux comes from libplist.
Problem: I ran "yum install libplist" and it told me libplist is already installed and latest version. I've read that if I enter the following command:
plutil -i /mypath/file.plist > /mypath/file.xml.plist
That this will help accomplish my ultimate goal. However, when I do this only a blank file called file.xml.plist is created. Further, with this command and any other command involving plutil, I get a "bash: plutil: command not found. . ." error. Is libplist seemingly not installed (even though it says it is) or why would I repeatedly get this error? Thanks for your help.
You can use yum to look for a package knowing the binary you want. For instance, if I want to install the package that provides plutil, I simply run this command:
$> yum provides plutil
Unfortunately, the result is No matches found... But you say you read that the libplist package provides this tool. Maybe it was renamed ? Let's use repoquery for this (if you don't have it, yum provides repoquery tells you that you need to install yum-utils).
$> repoquery --list libplist
/usr/bin/plistutil
/usr/lib/libplist++.so.3
/usr/lib/libplist++.so.3.0.0
/usr/lib/libplist.so.3
/usr/lib/libplist.so.3.0.0
/usr/share/doc/libplist
/usr/share/doc/libplist/AUTHORS
/usr/share/doc/libplist/COPYING.LESSER
/usr/share/doc/libplist/README
And what I see is that a program called plistutil was installed with this package !
I've never used plutil, so I can't tell you for sure plistutil is the program you want (but it probably is). What I wanted to do instead with this post is to show how you can use yum to install the packages you need !
I ran across this thread while Googling for the same thing myself. After looking at a few solutions for my own company (Screenplay) I decided to fork and iterate on a open-source, cross-platform, drop-in replacement for plutil:
https://github.com/screenplaydev/plutil
It's forked from Facebook's xcbuild (a tool developed by them to build xcode projects on Linux), but stripped down to just provide plist-editting functionality. That way you won't need to maintain separate code-paths for Mac and Linux environments.
Hope that's helpful!
warning: noob question ahead :-)
I was trying to run go get github.com/astaxie/beego but it does nothing. I have been running examples I picked up from the internet and I installed gotour successfully. Any idea why?
Turns out my setup was messed up. I purged everything and installed golang using this nifty script: https://github.com/moovweb/gvm. It takes care of everything. Thanks #peterSO for the help.
If it doesn't show anything, it doesn't mean nothing works. Try doing the same with '-v' flag
go get -v github.com/astaxie/beego
Besides, all your downloads will be saved (most probably) somewhere to your '~' directory ('~/go/src' in my case), not in your current terminal directory
if on Ubuntu/Debian?, try the golang package for installing go. it seems to work for me quite well.
This is sort of a followup to this thread--unfortunately I didn't make any progress at the time so I thought I would start over. I am consistently getting this in the debugging log (QtCreator 2.3.1, Qt 4.7.3, gdb 7.2):

The specific problem is that without the debugging helper, I'm unable to see the contents of QStrings and many other data structures during the debugging process, which makes it much more time-consuming. The error messages above are symptomatic, the problem arises when gdb can't find the debugging helper.
Anyway, looking at the discussion referenced in the answer in the above thread, I hunted around for different versions of gdb on my system but each one of them produced the same error (with the path changed appropriately of course), including version 7.3.1 when I downloaded it. I've also located libDebuggingHelper.so, but sticking it in different places hasn't helped either. Lastly looking at ./configure --help for gdb, I didn't see any options for enabling/disabling python in the build. Anybody know how I can get this to work?
This site claims you need to configure GDB using
./configure --with-python
It's pretty clear from the error message that the GDB you built does not have python support compiled in.
In gdb/config.log look for messages like checking whether to use python and see why GDB decided to not use Python on your system.
Perhaps you need to install Python development packages?
Once you've configured GDB to use Python, an easy way to check whether Python support is properly compiled in is:
(gdb) python print "hello"
If that prints anything other than hello, you are still not where you want to be.
I solved the problem with
sudo apt-get install gdb-multiarch
Thanks to #Employed-Russian for allowing me to check if GDB indeed has python support.
I did have to use the syntax
(gdb) python print("Hello")
To get a proper response from python within GDB.
I have just read the Ruby User's Guide at http://www.rubyist.net/~slagell/ruby/getstarted.html, I didn't find what I was looking for... which is, How do I use ruby source which I downloaded? There's a Makefile in it, do I just run GNU make -f like for any other source?
All I am trying to do is build and use whatweb (https://github.com/urbanadventurer/WhatWeb/wiki/Installation) from its source package.
Please do read READMEs developers provide. The README will point to https://github.com/urbanadventurer/WhatWeb/wiki/Installation which describe the installation process.
There you find that you need to install dependencies. As already stated Ruby is interpreted and does not need to be compiled.
....If I understad it well, you shouldn't build it(Ruby is an interpreted language). You just run the script like:
$ ./whatweb slashdot.org reddit.com
at "2. Example Usage" from whatweb documentation..
Is that what you need?
