[Bug] IMHEX_OFFLINE_BUILD not working properly

[xoores]

Operating System

Linux

What's the issue you encountered?

I'm adding the latest version of ImHex (1.36.2) to my portage overlay so Gentoo users can install it using standard package manager and the current version fails to build in the Gentoo sandbox even when I have IMHEX_OFFLINE_BUILD=ON-

How can the issue be reproduced?

Build from the latest sources in network sandbox.

ImHex Version

1.36.2

ImHex Build Type

• Nightly or built from sources

Installation type

Portage

Additional context?

Error, where some plugin seems to try & pull something from the internet during the compilation despite having OFFLINE_BUILD=ON:

Hey! Interesting, I'm not sure there's much I can do about that besides just disabling script support entirely. Are there any other packages that build .NET applications? How do they handle Nuget?

As a workaround for now, the easiest you can do is disable the script loader plugin using the following cmake variable:
-DIMHEX_EXCLUDE_PLUGINS="script_loader"

Aah, nice - I just deleted the offending folder and it build correctly without it 🙂 Thanks, definietly is a cleaner way to do it.

I'm not really sure - I will check that out. Normally things like that are done by "pre-downloading" all the packages/files necessary for the compilation. There also seems to be a nuget.eclass that (probably) might help with that, I will explore that for sure & let you know.
