Linux support

[technicalwonderland]

Hey,

I have a newest version of CEF, but after adding all lib files into appropriate folders into ThirdParty I get those issues:

In file included from /home/adam/perforce/StreamingVlc/Plugins/BLUI/Intermediate/Build/Linux/B4D820EA/UE4Editor/Development/Blu/Module.Blu.gen.cpp:4:

        ^~~~~~~~~~~~~~~~

Apart from standard libs I also added more, here is part of Blu.Build.cs :

			PublicAdditionalLibraries.Add(Path.Combine(ThirdPartyPath, "cef/Linux/lib", "libcef.so"));
			PublicAdditionalLibraries.Add(Path.Combine(ThirdPartyPath, "cef/Linux/lib", "libEGL.so"));
			PublicAdditionalLibraries.Add(Path.Combine(ThirdPartyPath, "cef/Linux/lib", "libGLESv2.so"));
			PublicAdditionalLibraries.Add(Path.Combine(ThirdPartyPath, "cef/Linux/lib", "libcef_dll_wrapper.a"));

			PublicIncludePaths.AddRange(
				new string[] {
					Path.Combine(ThirdPartyPath, "cef/Linux")
				});

Those libraries I've got from official download website. I also tried to build with this instruction, but BluBrowser: https://github.com/getnamo/BluBrowser but this also did not help.

Could you be so kind and help out with this one?

Kind Regards,
Adam.

There currently isn't a linux build. You'll need to modify BluBrowser to make a process equivalent of blu_ue4_process.exe found in BLUI/ThirdParty/cef/Win/shipping along with matching static libs. It's quite an involved process unfortunately and why we don't currently have a linux build unless a programmer spends the time and resources to make one.

can't you just download the cef precompiled binaries for the linux build and place it there? same if you want a newer version of cef on windows?

[nekwo]

if not is there a specific way it needs to be built for unreal?

See https://github.com/getnamo/BluBrowser for solution to build the process. I believe only minor modifications are used for the build.
