generate command fails UE 4.24.3 ERROR: Environment variable 'BinaryOutputDir' is not defined

When I attempt to run ue4 conan generate, the following error occurs. I'm pointing to a source tree for ue4.24.3, on win10.

Anything obvious I missed?

Conan package removed tools module

With the release of Conan 2.0 they seemed to have removed the tools module. Not sure how hard it would be to migrate to using a newer version of conan, but an Easy fix would be to specify
conan>=1.7.4,<2, in setup.py

The boilerplate module creates a folder named (literally) "$(ProjectDir)/Binaries/...." in the UE4 Source folder

This is probably due to the boilerplate code snippet:

		//Ensure our staging directory exists prior to copying any dependency data files into it
		string stagingDir = Path.Combine("$(ProjectDir)", "Binaries", "Data", "${MODULE}");
		if (!Directory.Exists(stagingDir)) {
			Directory.CreateDirectory(stagingDir);
		}

Possibly $(ProjectDir) should be ${ProjectDir} but I'm not (yet) familiar enough to know for sure.

BTW respecting how you are stong-arming all this build system/library chaos together :)

Conanfile doesn't have 'author'.

My organization requires the attribute_checker as hook in our conan config. So running generate fails with

[HOOK - attribute_checker.py] pre_export(): WARN: Conanfile doesn't have 'license'. It is recommended to add it as attribute
[HOOK - attribute_checker.py] pre_export(): WARN: Conanfile doesn't have 'description'. It is recommended to add it as attribute
[HOOK - attribute_checker.py] pre_export(): WARN: Conanfile doesn't have 'homepage'. It is recommended to add it as attribute
ERROR: [HOOK - attribute_checker.py] pre_export(): Conanfile doesn't have 'author'. It is mandatory to add it as attribute

when doing "Installing profile base packages...".

Not compatible with the latest conan(1.22.0)

ue4 conan build with the latest conan(1.22.0) makes an error as follows. It seems an recently added feature of conan in 1.22.0: from conans.tools import _global_config as config isn't set properly.

Conan-ue4cli for Unreal 5

Hello, I would like to know if Conan-ue4cli is compatible with Unreal 5

I tried to generate Conan profiles and wrapper packages but I got this error : ERROR: Couldn't find target rules file for target 'UE4Editor' in rules assembly 'UE5Rules, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'.

The command '/bin/sh -c ue4 conan generate' returned a non-zero code: 1

Could this have something to do with UBT needing to be pre-built?

Getting "Segmentation fault" while installing the package AND "ue4 build" fails.

Installing ue4cli and conan-ue4cli on linux host prints "Segmentation Fault" at the end.
Then I ran commands "ue4 setroot" and "ue4 conan generate" and they succeeded.
But when I tried to build the app "ue4 build", it failed.
"ue4 build" works for 4.26 in a container. This issue happened on linux host.

[ue4 conan generate] 'create --profile' failed w/ exit code 1, ends with "no build step" and "no module named 'ue4cli'"

hello. i'm working with

UE4.26.0, compiled from source
Windows 10 Home, version 20H2, build 19042.782
conan version 1.33.0
ue4cli is 0.0.51
conan-ue4cli is 0.0.35

no major changes to any default locations, however when i compiled UE i accidentally named the directory UE4.26, without the underscore. as part of my debug attempts here, i changed it to the traditional UE_4.26 format, ran the Engine\Binaries\Win64\UnrealVersionSelector-Win64-Shipping.exe tool and updated my path with ue4 setroot, and when none of that worked i then reinstalled both ue4cli conan-ue4cli.

editor runs fine, i ran clean.bat and a fresh build and repeated the above steps just to make sure. hopefully not a newbie mistake somewhere.

thank you for your time

Unable to generate Conan profile on macOS

I am currently on macOS (10.15.3) and the process fails when attempting to generate profile and packages using the ue4 conan generate command.
It appears to not be creating a json file (or the file can't be read for whatever reason) from the build tool.
I have downloaded a source checkout of UE4 engine and run the setup.sh to download the necessary files and set the root of ue4cli to the source code checkout.
I have Unreal 4.24.3 installed locally and the latest (as of today) version of UE4 source checked code checked out from GitHub.
Error message is below:

Question: packaging UE plugins as Conan packages?

Hi @adamrehn and co,

A potentially silly question incoming, but do you think it would theoretically be possible to bundle a regular UE plugin as a Conan package? At my studio we're currently using git submodules to include plugins within projects, and it's always felt uncomfortable to me, since I'm used to having proper dependency management with semantically versioned libraries. Having just started to use conan-ue4cli to package 3rd-party C++ libraries for UE projects, it occurred to me that it would be great if there was a way to use Conan as a dependency manager for UE plugins as well as vanilla C++ libraries.

Of course, since I'm fairly new to the UE world, I could be overlooking some obvious reasons why this might be a terrible idea.

Many thanks in advance!

ue4 setroot command gives error

Hello, I downloaded Unreal Engine 5.1.1 from the source and followed the Conan UE4 documentation. However, the 'ue4 setroot' command is not working, and it gives the following error.

When I run generate I get following error:

"

Running conan create . adamrehn/profile --profile=ue4 and conan create . adamrehn/profile --pr=ue4 seem to work. So I guess this is 'cause my profiles are not at user/.conan/profiles/

Btw, then it fails again complaining about not having a author attribute. But that is another issue.

Conanfile doesn't have 'author'. It is mandatory to add it as attribute

Cache of conan-ue4 is not invalidated

Configuration

OS: Windows 10
UE version: 4.26
conan-ue4cli version: 0.0.38

Steps to reproduce

Generate packages with UE4 third-party components as described in the instruction

cd c:\path1 
git clone --depth 1  -b 4.26.2-release git@github.com:EpicGames/UnrealEngine.git
ue4 setroot c:\path1\UnrealEngine 
ue4 conan generate

Remove cloned sources (del /s/q c:\path1\UnrealEngine)
Remove all generated packages from the local conan cache (conan remove "*adamrehn*")
Repeat step 1, but use another path for UE4 sources

cd c:\path2
git clone --depth 1  -b 4.26.2-release git@github.com:EpicGames/UnrealEngine.git
ue4 setroot c:\path2\UnrealEngine 
ue4 conan generate

The last operation, ue4 conan generate, looks for library paths into %AppData%\ue4cli\cache instead of searching through local file system. It can seen with the following snippet

from ue4lib import UE4Lib
png = UE4Lib("UElibPNG")
print(png)

Broken with conan 1.12

Attempting to build packages (especially the recipe packages) with conan version 1.12 (uploaded today) fails with the following:

In 4.20, RuntimeDependencyList in fact doesn't have 3-arg Add method.

conan-ue4cli selects v2 template for 4.20.

And v2 template tries to call 3-arg Add method.

Note that even v1 template does the same thing, so 4.19 is broken the same way.

3-arg Add method was only added in 4.21: https://github.com/EpicGames/UnrealEngine/commit/2d3ea5e946fd004fad40624ba9f51b6d2a1b4875

Change 4234711 by Ben.Marsh

	UBT: Runtime dependencies can now be copied to output directories as part of the build. When adding a runtime dependency, an optional source location can be specified to copy from. Both the source and target paths can use variables can be used as part of the path, eg. $(OutputDir), $(ModuleDir), $(PluginDir).

	Example usage (from a .build.cs file):

	RuntimeDependencies.Add("$(OutputDir)/Foo.dll", "$(PluginDir)/Source/ThirdParty/Foo.dll", StagedFileType.NonUFS);

Broken by e10f742 + 2c3c900.

Cross compiling Windows > Linux

Is it possible to crosscompile the libraries on windows for linux ?
