Hi, you can add " set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -no-pie -fno-exceptions -std=c++11 -Wno-deprecated-declarations -Wno-reorder") " to CMakeList below line 70.It worked for me! |
|
@flykule Thank you for commenting! I am going to try this out. |
|
@flykule Thank you so much! I have to modify a bit to: set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -no-pie -fexceptions -std=c++11 -Wno-deprecated-declarations -Wno-reorder") |
Compiling with -no-pie option just for one library (freetype2) sounds a little bit strange. In my opinion the prebuilt of libfreetype.a should be compiled with -fPIC option, or i am wrong? Sorry, i am not a compiler/linker expert. If you remove the dependency to libfreetype.a (i.e. in link.txt) you are able to successfully link everything with a clean/new project. I compiled and linked the libfreetype.a by myself and replaced it with the prebuilt. Now it's linking. |

@playmyskay Yeah, true perhaps. I have tried a few things, so far and nothing works. elseif(LINUX)
#target_compile_options(${target} PUBLIC -fPIC)
#target_compile_options(${target} PUBLIC -no-pie) |
|
step1:
output file: step2: file to replace: The file in repo 'https://github.com/cocos2d/cocos2d-x-3rd-party-libs-bin' must be replaced with a correct binary. |
Thank you very much i had the same problem and it solved it |
|
It solve by rollback gcc version and g++ version ,reference the file ........
sudo update-alternatives --remove-all gcc
sudo update-alternatives --remove-all g++
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 60
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.9 60
echo "Cocos uses GCC Version: `gcc --version`"
echo "Cocos uses G++ Version: `g++ --version`"
echo "Cocos uses ld Version: `ld --version`"
echo "Cocos uses /usr/bin/ld Version: `/usr/bin/ld --version`"the "-fPIC" error occur because gcc\g++ version too new (ubuntu17 or 18) , may be cocos2d-x should update gcc version |
|
i think we can use ubuntu 18 for next the testing version |
|
That would be fantastic, @minggo! I just started learning Cocos and this was a pain point. |
|
Just to share another [easier] solution for 3.17.1 (Ubuntu 18.04 LTS / LinuxMint 19.1): (Edit) Note: The package libfreetype6-dev must be installed. |
|
I just had a similar issue with libfmod:
How can I solve it? |

Can you improve the documentation for cocos2dx installation in Linux? It’s best not to set the operating system dependency. but I can’t see it in the documentation. I use kubuntu 20.04 |
