Compile error on WebSocket.cpp #32

Closed jacobdeery closed 6 years ago

jacobdeery commented 6 years ago

Running Unreal 4.18 on Ubuntu 16.04.

When I try to build this plugin I get a compile error:

ThirdParty/OpenSSL/1_0_2h/include/Linux/x86_64-unknown-linux-gnu/openssl/ossl_typ.h:172:9: error: 
      'UI' macro redefined [-Werror,-Wmacro-redefined]
#define UI OSSL_UI
        ^
/home/jd/development/anm_unreal_sim/submodules/base_unreal_project/Plugins/UROSBridge/Source/UROSBridge/Private/WebSocket.cpp:26:9: note: 
      previous definition is here
#define UI UI_ST

However, if I comment out lines 26 & 30 on WebSocket.cpp (#define UI UI_ST and #undef UI), the plugin compiles without errors.

Hi, thanks for the input. This error should not appear in 4.19. However your workaround is correct.
