Compiling Hydra Visual Plugin Module Project, but error "lc.exe exited with code -1"

Anderson_Gregorio · October 13, 2025, 1:35pm

Hi

I’m trying compile a Hydra Project, but often got the error in Visual Studio “Error “lc.exe exited with code -1”.

Redownload the licences throgh Everwood, but the error persists.

So I’ve checket the licence file “licenses.licx“ and seems ok, it isn’t tied to a specific version, containing the texts below:

_______________________________________________________

“RemObjects.Hydra.VisualPlugin, RemObjects.Hydra
RemObjects.Hydra.NonVisualPlugin, RemObjects.Hydra” _______________________________________________________

Specs:

OS: Windows 11

Hydra: Installed in both Visual Studio version 2019 and 2022

Hydra version: 6.7.0.1355

.Net Framework Version: 4.8

Project Type: Hydra Plugin Module .Net Framework

So I’ve created an example from scratch, and got the same error.

HydraPluginModule.NetFramework.zip (14.6 KB)

Thx

Hi,

I’ve no issue with your testcase:

Rebuild started at 5:19 PM...
1>------ Rebuild All started: Project: HydraPluginModule.NetFramework, Configuration: Debug Any CPU ------
1>  HydraPluginModule.NetFramework -> C:\Users\VM\Documents\HydraPluginModule.NetFramework\HydraPluginModule.NetFramework\bin\Debug\HydraPluginModule.NetFramework.dll
========== Rebuild All: 1 succeeded, 0 failed, 0 skipped ==========
========== Rebuild completed at 5:20 PM and took 49.860 seconds ==========

I’ve used VS2022

Is there a way to check if Hydra is correctly installed in Visual Studio?

Hi,

I think, you can just reinstall Hydra.
It should fix potential issues

Hi

Reinstalled and created another application from scratch in Visual Studio 2022, but the problem persists

Hi,

try to do these steps:

close VS
remove Obj folder inside project
launch Developer Command Prompt for VS 2022
locate folder with your project
launch msbuild
you will have something like

copy command related to lc, add /v parameter and execute.

it should show why you have Error “lc.exe exited with code -1.

Hi

It doesn’t show the problem anymore, may be something related to Obj temporary debug file

Thank you

EvgenyK · October 14, 2025, 12:13pm

Hi,

I wonder why it failed with new project created from scratch …

Probably re-installation of Hydra solved original issue, but Obj folder still contained some files that caused failure…
