General / Re: CMake - SFML dependency issues

« on: March 26, 2023, 03:50:27 pm »

I see - so there is no way to omit this? It would be nice if people could just run the cmake script without any other steps - I could make a bash script I guess - would the CMAKE run fine on windows?

General / CMake - SFML dependency issues

« on: March 26, 2023, 12:38:16 pm »

I've started to word on the build scripts for one of my SFML projects - but I keep running into dependency problems with the modules: OpenAL, Vorbis and Flac - here is the error I get for a given dependency:

Code: [Select]

CMake Error at /usr/share/cmake-3.18/Modules/FindPackageHandleStandardArgs.cmake:165 (message):
  Could NOT find FLAC (missing: FLAC_LIBRARY FLAC_INCLUDE_DIR)
Call Stack (most recent call first):
  /usr/share/cmake-3.18/Modules/FindPackageHandleStandardArgs.cmake:458 (_FPHSA_FAILURE_MESSAGE)
  build/_deps/sfml-src/cmake/Modules/FindFLAC.cmake:16 (find_package_handle_standard_args)
  build/_deps/sfml-src/cmake/Macros.cmake:279 (find_package)
  build/_deps/sfml-src/src/SFML/Audio/CMakeLists.txt:71 (sfml_find_package)
To fix these I need to install the lib[module]-dev packages for each dependency with apt, but is there a way I could integrate the installation of such dependencies into the cmake build files. Here is a basic CMakeLists.txt file which should just compile a simple "hello world" SFML project, what could I add to resolve these problems? :

 1 cmake_minimum_required(VERSION 3.18)
 2 project(SfmlBasic VERSION 1.0)
 3 include(FetchContent)
 4 set(BUILD_SHARED_LIBS ON)
 5 FetchContent_Declare(
 6  SFML
 7  GIT_REPOSITORY https://github.com/SFML/SFML.git
 8  GIT_TAG 2.5.1
 9 )
10 FetchContent_MakeAvailable(SFML)
11 set(CMAKE_CXX_STANDARD 11)
12 set(CMAKE_CXX_STANDARD_REQUIRED true)
13 add_executable(
14  SfmlBasic
15  main.cpp
16 )
17 target_link_libraries(
18  SfmlBasic
19  sfml-graphics
20 )

Ah thanks so much.
I'm surprised I never came across that page you linked before now.

General / Why does this link chain not work (SFML static link)

« on: October 24, 2022, 05:22:58 pm »

I'm having issues statically linking a program on windows 10.
I have built SFML with cmake and now need to statically compile my code.
To do this I am using a Makefile that looks like this:

all:
    g++ main.cpp -o wampus.exe -DSFML_STATIC -I C:\lib\SFML\include -L C:\lib\SFML\lib -lsfml-window-s -
    lsfml-system-s -lopengl32 -lwinmm -lgdi32 -lsfml-graphics-s -lfreetype -lsfml-audio-s -lopenal -lflac
    -lvorbisenc -lvorbisfile -lvorbis -logg

When I run mingw32-make all,  I get a pretty massive chain of errors, presumably because this link chain is not in the correct order. It there a way I can fix this?

Error snippet:

Ah thank you!
Still the same issue however.
Though this time the error is shorter and only talks about graphics and audio.
