To build Bullet's static libraries files I've used CMake, and as specified by UE4 doc I've to build it using /MD because UBT will generate a .dll file of Thirdparty library (in this case Bullet) https://wiki.unrealengine.com/Linking_S ... ild_System
The building of Bullet has no problem, but when I try to build the UE4 source it fail with this error: unresolved external symbol _DllMainCRTStartup
This is Bullet's CMake configuration is attached
Code: Select all
Creating makefile for UE4Editor (no existing makefile) 2> Performing 2 actions (4 in parallel) 2> [1/2] Link UE4Editor-Engine.dll 2> [2/2] Link UE4Editor-Bullet.dll 2>LINK : error LNK2001: unresolved external symbol _DllMainCRTStartup 2>D:\WorkSpace\GitHubProjects\UE_4.16\UnrealEngine\Engine\Binaries\Win64\UE4Editor-Bullet.dll : fatal error LNK1120: 1 unresolved externals 2> Creating library D:\WorkSpace\GitHubProjects\UE_4.16\UnrealEngine\Engine\Intermediate\Build\Win64\UE4Editor\Development\UE4Editor-Engine.suppressed.lib and object D:\WorkSpace\GitHubProjects\UE_4.16\UnrealEngine\Engine\Intermediate\Build\Win64\UE4Editor\Development\UE4Editor-Engine.suppressed.exp 2>ERROR : UBT error : Failed to produce item: D:\WorkSpace\GitHubProjects\UE_4.16\UnrealEngine\Engine\Binaries\Win64\UE4Editor-Bullet.dll
I've written to UE4 forum https://forums.unrealengine.com/showthr ... e&p=728173 (where there are a bit more information about steps i did) but I think the problem occurs due to Bullet's cmake configuration for this reason I'm writing here. I've found some threads that talks about this problem but they doesn't resolve the problem.
What cause the requiring of _DllMainCRTStartup symbol?
How can I resolve it?
