Greetings,
So finally got SFML working now trying to get TGUI working.
Linux Mint - 19.1, 64-bit.
SFML: 2.5.1
TGUI: 0.8.4
g++ compiler, cmake and make - all up-to-date.
I tried installing TGUI from the PPA - however, it kept giving me warnings that it was trying to use an older version of SFML (2.4.1) which got installed as a requirement - however, I wanted to use the "latest" stuff (may or may not be a requirement - BUT I would prefer it).
I downloaded the source of both SFML and TGUI - successfully built both of them (to ensure they work together and with compiler).
now trying to create a project and having issues with an sf::String::operator.
I am using CMakeLists.txt to generate the project (just started to learn the basics for cmake): follows:
---------------------------------------------------------------------------------------------------------------------------------------------------------
cmake_minimum_required(VERSION 3.10.2)
project(PROJECTNAME_REMOVED_FOR_REASONS)
include_directories(../includes includes includes/gameManagement)
file(GLOB SOURCES "src/*.cpp" "src/gameManagement/*.cpp")
set(SFML_DIR "../Base/SFML-2.5.1/lib/cmake/SFML")
set(TGUI_DIR "../Base/TGUI-0.8.4")
find_package(SFML 2.5.1 COMPONENTS system window graphics REQUIRED)
find_package(TGUI 0.8.4 REQUIRED)
add_executable(EXEC_NAME ${SOURCES})
target_link_libraries(EXEC_NAME sfml-system sfml-window sfml-graphics tgui)
---------------------------------------------------------------------------------------------------------------------------------------------------------
the output I get is:
---------------------------------------------------------------------------------------------------------------------------------------------------------

Is what is giving me the issue... I saw someone else had this issue https://forum.tgui.eu/installation-help/undefined-reference-to-sfstringoperator/
However, that is not helpful for the current version. If all else fails - yes I can just download the versions of SFML and TGUI as found in the package manager >_>...
Thanks
