General / Re: error adding symbols: Archive has no index

« on: January 08, 2021, 09:29:34 pm »

As it turns out, I WASN'T building SFML and running the project with the same compiler. I have two versions of mingw-64 installed on my computer and even though I had specified which to use, CMake still used the other one. I only discovered this after deleting the other version and trying to run again, it told me the compiler was missing. Once I rebuilt everything with the right compiler everything worked.

General / error adding symbols: Archive has no index

« on: January 08, 2021, 09:12:55 pm »

I'm getting this strange error when trying to build my project:

C:/Program Files (x86)/SFML/lib/libsfml-graphics-s.a: error adding symbols: Archive has no index; run ranlib to add one
 

I built SFML myself on windows using this guide: https://www.sfml-dev.org/tutorials/2.5/compile-with-cmake.php and installed SFML into the the windows program files. I'm completely certain that I'm using the same compiler to build SFML and my project. I tried running ranlib over libsfml-graphics-s.a but it didn't seem to do anything.

Here's what my CMakeLists.txt looks like:

cmake_minimum_required(VERSION 3.17)
project(SFML_test)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -static")
set(CMAKE_VERBOSE_MAKEFILE ON)

file(GLOB SOURCES ./*.cpp)
add_executable(SFML_test ${SOURCES})

# SFML
set(SFML_STATIC_LIBRARIES TRUE)
set(SFML_DIR "C:/Program Files (x86)/SFML/lib/cmake/SFML")
find_package(SFML COMPONENTS graphics window system REQUIRED)
target_link_libraries(SFML_test sfml-graphics sfml-window sfml-system)

General / Undefined references when building test project (Windows 10/CLion)

« on: January 07, 2021, 10:26:09 pm »

Hi there,

I'm just trying to get my SFML setup working properly so I can get started on a project and I've spent the past day trawling through forum posts old and recent but none of the fixes suggested before have worked for me.

I have built SFML myself using static libraries with the CMake GUI. I am using the CLion IDE.

Here is the contents of my CMakeLists.txt file:

cmake_minimum_required(VERSION 3.17)
project(SFML_test)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -static")
set(CMAKE_VERBOSE_MAKEFILE ON)

file(GLOB SOURCES "./*.cpp")
add_executable(SFML_test ${SOURCES})

# SFML
set(SFML_STATIC_LIBRARIES TRUE)
set(SFML_DIR "C:/Program Files (x86)/SFML/lib/cmake/SFML")
find_package(SFML 2.5 COMPONENTS system graphics window audio REQUIRED)
target_link_libraries(SFML_test sfml-system sfml-graphics sfml-window sfml-audio)
 

Here is the full build log with the error when I try and build:

I've tried switching around the linked libraries with no luck. I'm sure there's something very simple that I'm missing. Any help would be appreciated, thanks!
