Delve: Mac OS Sierra 10.12.2 - Delve install via Homebrew broken

[andrewbruno]

Please update the documentation to highlight that it does not work on OSX 10.12.2

Error message is: could not launch process: could not get thread count

This is how I got it to work:

— Install via brew
— then you need to change delve version locally.

cd $GOPATH/src/github.com/derekparker/'
cd delve
git fetch origin pull/665/head
git checkout FETCH_HEAD
CERT=dlv-cert make install

Make sure you run the one you built, i.e. $GOPATH/bin/dlv debug

@andrewbruno Thanks for this.
Are you cloning the repo into $GOPATH/src/github.com/derekparker/ before you git fetch origin pull/665/head? Or should brew be putting it there?
I've been trying every combination in 10.12.2 with no luck.
Thanks!

@aaronhackney I followed these two instructions on how to do a manual install (after installing with brew).

• Make directory mkdir $GOPATH/src/github.com/derekparker && cd $GOPATH/src/github.com/derekparker as typical in Writing go programs
• Clone this project: git clone https://github.com/derekparker/delve.git && cd delve

And then used @andrewbruno's instructions to get it working.

Thanks for the feedback. Here is what I have learned:

1. I installed on my home iMac running 10.12.2 using the HEAD method and delve works just fine!

2. Installing on my Macbook Pro Laptop, which has my company's corporate image on it, I get the errors and it does not work. I used the exact same method and I'm running the exact same version of 10.12.2. I suspect there is some corporate security software that is preventing delve from accessing the threads, even though, when prompted, I entered my credentials with super-user access. Perhaps it's anti-virus or something. I'm not sure. I'm going to attempt to find out from our help desk what we may be running that could be interfering with delve's thread access. Thanks again for the suggestions!

Here is a gist of a successful install on 10.12.2 if anyone is interested.

Thanks!

Can confirm this worked for me!

[aaronhackney]

I was able to trace my issue to the Crowd Strike Falcon Host protection client installed on my MBP. https://www.crowdstrike.com/products/falcon-host/ Once I removed this client, the thread issues went away. We have opened a ticket with CrowdStrike to see if we can get delve whitelisted.

@derekparker Since the Mac OSX issue seems to come up a lot in the issues section, I made a quick howto detailing as many steps as I could. https://github.com/aaronhackney/delve_on_mac
Thanks again for your project!

[jsaguiar]

this worked for me:
brew install go-delve/delve/delve --HEAD

[derekparker]

This should be solved, the latest version of Delve should now be available in the latest HomeBrew formula as of https://github.com/go-delve/homebrew-delve/commit/f27054f461fbe547dd95abac4f70df18f6782e24 (merged 4 days ago).

From: https://github.com/go-delve/homebrew-delve/blob/master/Formula/delve.rb
==> Dependencies
Build: go ✔
==> Caveats
If you get "could not launch process: could not fork/exec", you need to try
in a new terminal.

When uninstalling, to remove the dlv-cert certificate, run this command:

$ sudo security delete-certificate -t -c dlv-cert /Library/Keychains/System.keychain

Alternatively, you may want to delete from the Keychain (with the Imported private key).

the go version go1.9.2 darwin/amd64
it's not work for me
macOs version 10.13.2

[unjello]

Same here. macOS 10.13.3, --HEAD or not, cannot install delve with exact same error.

[mihei]

@unjello also on macOS 10.13.3, this worked for me:

• xcode-select --install
• brew install go-delve/delve/delve --HEAD

$ dlv version
Delve Debugger
Version: 1.0.0-rc.2

and

go version go1.9.3 darwin/amd64

[unjello]

@mihei hmm... wierd. It did indeed install today as you say. Maybe just a glitch in a spore network. Thanks for making me re-try it!

[koliyo]

Same problem for me on 10.13.3 (17D47)

brew install -vd go-delve/delve/delve --HEAD

If this was mentioned on the install page it would have saved me a lot of trouble.

The fix mentioned here works for me
