offline build

[rexainn]

How can I change the CMakeLists or any other file to make sure "we don't download dlg from the github"?

I can download the dlg on my own laptop and pass it on the server, but I can't download from "https://github.com/nyorain/dlg.git/" while building hello_imgui.

[pthom]

Try to run git submodule update --init manually instead of relying on CMake to do it for you. It seems that cmake fails on https in your case.

Keep me informed, please

[rexainn]

The problem is that git submodule update --init not works, because my server can't access github. So I need to manually install on my laptop and pass it on the server. But I don't know where to store dlg in the hello_imgui.

[rexainn]

And dlg is the dependency of freetype, it's not in the git submodule

[pthom]

git submodule update --init does not work?

That is the first important issue. Can you clone a anything from github? How did you clone the repository in the first place? May be you are facing a temporary issue with github. In the meantime -DHELLOIMGUI_USE_FREETYPE=OFF

[pthom]

... but you will likely fail on the next dependency: glfw

[pthom]

Otherwise, for a build without connection, first install the dependencies with vcpkg (you will need to have installed freetype and glfw)

[rexainn]

nope...in china, the github need vpn to access, but my server can't set a vpn. So I download everything needed on my own laptop, and pass it on the server through sftp.

So I want to know how can I make all the dependencies from the local dir, and not download again from the github on the server.

[rexainn]

Ok, so I need to build entirely freetype and glfw first, then build imgui_bundle, then it will not download them again.

[rexainn]

I've built freetype successfully, but when I run pip install -v . for imgui-bundle, it still try to download and build freetype from github.

Success on freetype before:

[pthom]

Because it needs a newer version of freetype than the one available with apt-get.

Use vcpkg, or add submodule for freetype and glfw + add_subdirectory for them before adding imgui_bundle

[rexainn]

It's the newest version from official: https://github.com/freetype/freetype, I built it from source.

I'm sorry but how can I add submodule + add_subdirectory for imgui_bundle? I think this is the point. I've built the freetype but not in a imgui_bundle known way.

[pthom]

I just understood you are trying to build a pip package, which you did not mention clearly.

There is no easy way to bypass the download for pip building now.

My advice: build a wheel on a machine connected to the internet and use this wheel on your server.

[pthom]

I added some doc for vcpkg + offline usage:
