I'm trying to build the libdepixelize library , but I'm getting the following error:

I'm using clang with libstdc++ as compiler. GCC didn't work either.
EDIT: I used this in the CMakeLists file: set(CMAKE_CXX_FLAGS "-std=c++11 -stdlib=libc++") and then did cmake -DCMAKE_CXX_COMPILER="clang++" .. and make to compile it. The full log is here: https://hastebin.com/axasololuc.js
I have no idea what exactly it means, or even how to fix it.

I am trying to build xalan-c (version 1.12) with icu in Ubuntu but it fails.
Could anyone help me with this.
Environment : Ubuntu 20.04
Steps to reproduce :
Clone xalan-c
cmake -G "Unix Makefiles" -DCMAKE_PREFIX_PATH="path to vcpkg installed libraries" -DCMAKE_INSTALL_PREFIX=./install/Xalan-c -DCMAKE_BUILD_TYPE=Debug -Dtranscoder=icu "path to source"
make

Please note I have applied a patch for configuration error as below in src/xalanc/Utils/MsgCreator/CMakeLists.txt

changed to

I've been trying to build a piece of code in webassembly that would use OpenCV.
I took https://github.com/mpizenberg/emscripten-opencv to start building, this worked well, but when I try adding cv::resize to be able to resize an image, that's when I have some issues:

I tried wrapping up my problem here https://github.com/jdrouet/opencv-wasm, you can pull it and run make, it'll build with docker.
Do you have any idea of how I could fix my issue?
Ok, looks like I found a way to build it (still here https://github.com/jdrouet/opencv-wasm) but now, when I try to use the resize function, I end up with the following error :
Error: the string "174007712 - Exception catching is disabled, this exception cannot be caught. Compile with -s DISABLE_EXCEPTION_CATCHING=0 or DISABLE_EXCEPTION_CATCHING=2 to catch." was thrown, throw an Error :)
So now, I don't know if I'm not using the function well... Here is the function : https://github.com/jdrouet/opencv-wasm/blob/master/source/resizer.cpp#L23
Do you have any idea of why it's not working?
i learn c++, OpenMP. I have tried compile my program with omp_get_wtime and it doesn't work, but when i deleted this, it works. i must add something, but what and where. In openmptryflags or Cmakelists?

Solution :
add to CMakeList.txt
SET_TARGET_PROPERTIES(omp1 PROPERTIES COMPILE_FLAGS "-fopenmp"
LINK_FLAGS "-fopenmp")
P.s. omp1 - name your project.
P.p.s. also you can write target_link_libraries(omp1 -fopenmp)
The following error occurs when I am building eos using cmake on macOS.

make: *** [all] Error 2
I find some related issues, but they are seemingly all about ios and xcode and I don't know what I should do in a project like eos. How can I fix it?
I meet the same 2 errors when building from source code of EOS step by step.
Alternatively You can use another method by running the script(https://github.com/EOSIO/eos#automac):
./build.sh darwin
When I build a project with cmake, I got following error. Though I tried to add compiling flag -fPIC by add_definition() in the CMakeLists.txt, this error persists. Can anyone help? I am a new guy to cmake. Any suggestions will be highly appreciated.

add_definitions is is intended to add preprocessor definitions, not a flag
-fPIC is present by default in the linker flags for a shared library build with GCC, see Modules/Compiler/GNU.cmake. You can see all flags by running make VERBOSE=1.
As for the error itself, see this answer.
