Compilation error

Compilation error

OpenFoam-User opened this issue 4 years ago · comments

Hello,
In Ubuntu 20.04, when I try to compile it, I get the following error:

In file included from /tmp/NoCol/src/display_manager.cpp:1:
/tmp/NoCol/include/display_manager.hpp:4:10: fatal error: event_manager.hpp: No such file or directory

Yes I see why, I will update the code

Jean Tampon · Answer 2 · Thu Jun 25 2020 19:30:15 GMT+0800 (China Standard Time)

Should be better, I updated master

I got another error:

I did push some fixes and now it is working fine but with visual studio 2017. However the CMakelists is OK. Did you build in release mode ? Debug is not supported for now

OpenFoam-User · Answer 5 · Thu Jun 25 2020 23:40:17 GMT+0800 (China Standard Time)

Still the same error. I was following these steps:

git clone <url of this repo>
cd NoCol
cmake .
make
That didn't work (error above), I used ccmake to change the build type to Release but still getting the same error.

OpenFoam-User · Answer 6 · Thu Jun 25 2020 23:49:11 GMT+0800 (China Standard Time)

My guess is that it compiles against static libraries with extension .lib which are available only for Windows. For linux it should pick up the .a version.

Jean Tampon · Answer 7 · Thu Jun 25 2020 23:52:13 GMT+0800 (China Standard Time)

That's a good point, in this case I would suggest that in the CMakelists you replace the .lib by the correct ones. It is not a good solution but I am a noob with these build tools. Also maybe create a build dir ?

git clone <url of this repo>
cd NoCol
mkdir build
cd build
cmake ..
make

OpenFoam-User · Answer 8 · Thu Jun 25 2020 23:55:18 GMT+0800 (China Standard Time)

Actually the problem is with CMakeLists.txt file, I changed it as follows, and now it works!

cmake_minimum_required(VERSION 3.10)

set(PROJECT_NAME NoCol)
project(${PROJECT_NAME} VERSION 1.0.0 LANGUAGES CXX)

set(SFML_DIR "" CACHE PATH "SFML lib path")
set(SFML_LIB_DIR "${SFML_DIR}/lib")
set(SFML_INC_DIR "${SFML_DIR}/include")

find_package(OpenGL)

set(SFML_LIBS "sfml-graphics"
    "sfml-window"
    "sfml-system"
    "freetype"
    "${OPENGL_LIBRARIES}"
)

file(GLOB source_files
	"src/*.cpp"
)

set(SOURCES ${source_files})

add_executable(${PROJECT_NAME} ${SOURCES})
add_definitions(-DSFML_STATIC)
target_include_directories(${PROJECT_NAME} PRIVATE "${SFML_INC_DIR}" "include")
target_link_libraries(${PROJECT_NAME} ${SFML_LIBS})

Good job :)

kritonpc · Answer 10 · Sat Jun 27 2020 22:26:13 GMT+0800 (China Standard Time)

set(SFML_DIR "" CACHE PATH "SFML lib path")
set(SFML_LIB_DIR "${SFML_DIR}/lib")
set(SFML_INC_DIR "${SFML_DIR}/include")

how did you install SFML?

Jean Tampon · Answer 11 · Sat Jun 27 2020 23:07:53 GMT+0800 (China Standard Time)

I compiled it myself (it is well explained here https://www.sfml-dev.org/tutorials/2.5/compile-with-cmake.php). But you can also use the official repo of your linux distrib or, if you know your compiler version, download the right one here https://www.sfml-dev.org/download/sfml/2.5.1/

I've tried pretty much everything, but all I get is errors... Tried on windows, also got errors...

sudo apt install libsfml-dev

kritonpc · Answer 14 · Sun Jun 28 2020 04:01:37 GMT+0800 (China Standard Time)

sudo apt install libsfml-dev

I've tried this too.. didn't work...

Jean Tampon · Answer 15 · Sun Jun 28 2020 04:58:56 GMT+0800 (China Standard Time)

Excuse me, I didn't saw the logs you sent me. The problem you have is not related to sfml. Do you have the latest version of the repository? It seems it cannot find the event manager. Le sam. 27 juin 2020 à 22:01, kritonpc <notifications@github.com> a écrit :

Yes. I have the lastest one. I can't understand what's going on... It's really confusing. Tried it on windows and it still has issues.

@kritonpc : What are the issues? what error did you get? please provide more details, I will try my best to help.

He has this error

 #error This file requires compiler and library support \

which suggests the compiler doesn't have c++11 support enabled

Jean Tampon · Answer 20 · Mon Jun 29 2020 01:35:15 GMT+0800 (China Standard Time)

I did update the CMakelists, can you pull, regenerate project and try to compile it to see if it works better ?

kritonpc · Answer 21 · Mon Jun 29 2020 01:56:59 GMT+0800 (China Standard Time)

I still have issues. I think it might be due to SFML. Which way did you install it?

Jean Tampon · Answer 22 · Mon Jun 29 2020 01:58:51 GMT+0800 (China Standard Time)

Can you share the logs you have when you try to compile please ?

kritonpc · Answer 23 · Mon Jun 29 2020 02:12:08 GMT+0800 (China Standard Time)

it says it needs "sfml-graphics-s.lib", while i find "libsfml-graphics.so"

Jean Tampon · Answer 24 · Mon Jun 29 2020 02:24:45 GMT+0800 (China Standard Time)

Yes, I forgot that you also need to remove the .lib in the CMakeLists

kritonpc · Answer 25 · Mon Jun 29 2020 02:27:06 GMT+0800 (China Standard Time)

I tried it and I found the correct files, but i get this

I think this path is not normal '//usr/lib/x86_64-linux-gnu/lib/libsfml-graphics.so' I think it should only be one / at the beginning.

Because the error means it cannot find the file

@kritonpc : Try the following CMakeLists.txt

cmake_minimum_required(VERSION 3.10)
set(PROJECT_NAME NoCol)
project(${PROJECT_NAME} VERSION 1.0.0 LANGUAGES CXX)

set (CMAKE_CXX_STANDARD 11)
set(SFML_DIR "" CACHE PATH "SFML lib path")
set(SFML_LIB_DIR "${SFML_DIR}/lib")
set(SFML_INC_DIR "${SFML_DIR}/include")

find_package(OpenGL)

set(SFML_LIBS "sfml-graphics"
    "sfml-window"
    "sfml-system"
    "freetype"
    "${OPENGL_LIBRARIES}"
)

file(GLOB source_files
	"src/*.cpp"
)

set(SOURCES ${source_files})

add_executable(${PROJECT_NAME} ${SOURCES})
add_definitions(-DSFML_STATIC)
target_include_directories(${PROJECT_NAME} PRIVATE "${SFML_INC_DIR}" "include")
target_link_libraries(${PROJECT_NAME} ${SFML_LIBS})

I couldn't get it to work on ubuntu 16.04, but the good news is that it works on Ubuntu 18.04

Jean Tampon · Answer 31 · Mon Jun 29 2020 17:49:07 GMT+0800 (China Standard Time)

That's a good news. It might have something to do with default compiler options. On newer version default standard should be at least c++11.

@kritonpc How did you manage to install it in Ubuntu 18.04?

@kritonpc How did you manage to install it in Ubuntu 18.04?

I used the last CMakeFiles.txt, the one that you provided
