Build Shipping Failed


I tried to compile my game in shipping mode.

My library compile fine but the linking process is failing with this error:

boringssl.lib(boringssl.sha1.obj) : error LNK2005: SHA1 dÚjÓ dÚfini(e) dans websockets_static.lib(sha-1.obj)

fatal error LNK1169: One or more symbol defined in multiple places have been found

It is saying that SHA1 is already defined in websockets_static.lib(sha-1.obj)

I’m with the Launcher version.

As it is not link at all to my game library I supposed that this is an engine issue.
I hope you can repro this and provide a solution or give me some path to fix this.



Could you please upload your full error output logs as a .txt file? Please also try 4.14.0, provide those logs too in a separate file.

Sorry for the late answer. Here is the full log.

I can’t test 4.14 yet.


According to the errors I am seeing:

  • Error MSB3073 is likely due to an error in your code.

Did you change anything in: “C:\Program Files (x86)\Epic Games\4.13\Engine\Build\BatchFiles\Rebuild.bat”?


I just move to 4.14.1 this morning and was able to compile in release mode without issue. I bet there was something wrong in 4.13.

4.14 solve the issue without code changes.
