Unable to debug Go code: could not launch process: decoding dwarf section info at offset 0x0: too short

Question

we are trying to debug Go code and getting this error:

could not launch process: decoding dwarf section info at offset 0x0: too short

our settings:

WITSC02X6385JGH:orderer sjain68$ uname -a
Darwin WITSC02X6385JGH 17.7.0 Darwin Kernel Version 17.7.0: Fri Jul  6 19:54:51 PDT 2018; root:xnu-4570.71.3~2/RELEASE_X86_64 x86_64
WITSC02X6385JGH:orderer sjain68$ go version
go version go1.11 darwin/amd64
WITSC02X6385JGH:orderer sjain68$ dlv version
Delve Debugger
Version: 1.1.0
Build: $Id: 1990ba12450cab9425a2ae62e6ab988725023d5c

Things we have tried:

• Update dlv using VS Code -> Go: Install/Update Tools

Try running from command line:

WITSC02X6385JGH:orderer sjain68$ /Users/sjain68/go/bin/dlv debug github.com/hyperledger/fabric/orderer --headless=true --listen=127.0.0.1:41305 --api-version=2 --log=true --

Exiting.
could not launch process: decoding dwarf section info at offset 0x0: too short

Note that the binary that we are trying to debug does gets executed. Its just that the debugger does not launch.

Another thing we tried from this link:

WITSC02X6385JGH:orderer sjain68$ export GOFLAGS="-ldflags=-compressdwarf=false"; dlv debug
could not launch process: decoding dwarf section info at offset 0x0: too short

Someone said to run GOCACHE=off go build ... and output of that is pasted here.

How can we fix this?

Did you read this answer? – Firooc

Yes we have. Is there anything in that answer that we have not tried? – Memorial

Answer 1

The solution that worked for us was to upgrade Go version

$ go version
go version go1.13.3 darwin/amd64

So Go 1.11 is the culprit.

Answer 2

I had the same issue after updateing Go. Updating Delve package from console helped:

go get -u github.com/go-delve/delve/cmd/dlv

Answer 3

I was able to fix it using -ldflags=-linkmode internal

This fixed issue after upgrading to MacOS Sequia 15.0. Thx mate – Oralle

Answer 4

make sure you aren't using flags that remove the debug info from your build ie -ldflags="-s -w" .
