Hi,

I tried to build the Unreal 4.8 from source on Ubuntu 14.04, but got tons of errors.

I have no idea how to modify what files to fix these issues.

Can anyone give me some advice?

Thanks!

tegra-ubuntu? You seem to be using Jetson-TK1 or other non-x86_64 architecture. While you can build some targets for ARM, this is way less explored path than x86_64 Linux.

Change UEBuildLinux.cs to return default architecture as arm-unknown-linux-gnueabihf (look for DefaultArchitecture name in line 26) and try again.

Note that building the editor on Jetson is theoretically possible, but you will need code changes to remove certain libraries which don’t have ARM version (e.g. FBX SDK). I stronly suggest that you build on x86_64 machine first and then use that experience, build on ARM.

./Binaries/Linux/UnrealHeaderTool: symbol lookup error: so: undefined symbol: _ZNK6icu_5322UCharCharacterIteratoreqERKNS_24ForwardCharacterIteratorE
Error: Failed to generate code for CrashReportClient - error code: 127 (127)

I used echo|c++filt to find out the undefined symbol is actually be:
icu_53::UCharCharacterIterator::operator==(icu_53::ForwardCharacterIterator const&) const

ICU is the International Components for Unicode package. I think it is not necessary for the installation(?). But I cannot find which codes/includes I should comment.
Could you help me with that? Thanks in advance!

Hello,You mentioned removing the fbx sdk (because there is no arm64 version). Do you know anyone who has done this? Whether there are github projects or articles. I’m going to have to work on this, but I have no idea, thank you very much.
Best wish
