When I try OpenPose Building, I get error: identifier “nullptr” is undefined.
I follow the instructions on the site to install OpenPose and I have error in "OpenPose Building".

I believe that GCC 4.9 should be sufficient. The caveat is that it does not use C++11 by default, so you have to add --std=c++11 somewhere in the Makefile where the CXXFLAGS are defined. The developers of the software package might use a newer version of GCC which uses C++14 by default, like GCC 8.2.
As this is a CMake project, you can either add
add_definitions('--std=c++11')
to the CMakeLists.txt or add
set(CMAKE_CXX_STANDARD 11)
if your version of CMake supports it.

TLDR
Im building a static library and linking it to an executable. Im generating makefiles with cmake. When I generate the makefile for cl (The compiler from visual studio) I have no problems, but when I generate the makefile for clang I get an undefined symbol.
Versions:
cmake version 3.18.1
clang version 11.0.0
Target: x86_64-pc-windows-msvc
Thread model: posix
cl version 19.26.28806 for x64
Minimal Example
I have the following structure for the proyect:
Proyect Root
│ CMakeLists.txt
│ foo.cpp
│ foo.hpp
│ main.cpp
│
└───bin
And this are the contents of the files:
foo.hpp
namespace foo {
void do_stuff(void);
}
foo.cpp
#include <foo.hpp>
namespace foo {
void do_stuff(void) {}
}
main.cpp
#include <foo.hpp>
int main(void) {
foo::do_stuff();
return 0;
}
And CMakeLists.txt
cmake_minimum_required(VERSION 3.0.0)
project(CompileAndLinkLib)
include_directories(".")
file(GLOB FOO_SRC "foo.cpp")
add_library(foo STATIC ${FOO_SRC})
add_executable(main "main.cpp")
target_link_libraries(main foo)
Correct linking
First I call vcvarsall.bat. I generate a nmake file with the following command:
cmake .. -G "NMake Makefiles"
And compile with:
nmake
The project compiles and links correctly
The undefined symbol
I generate the make file with the following command:
cmake .. -G "Unix Makefiles" -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++
And when I compile with make I get the following output:
Scanning dependencies of target foo
[ 25%] Building CXX object CMakeFiles/foo.dir/foo.cpp.obj
[ 50%] Linking CXX static library foo.lib
[ 50%] Built target foo

make[2]: *** [main.exe] Error 1
make[1]: *** [CMakeFiles/main.dir/all] Error 2
make: *** [all] Error 2
Im not sure if im doing something wrong, like if im missing something, or if this is an error with the makefile generated by cmake.
I just had the same problem, but with Clang 13. It could be solved with specifying clang as compiler in the CMakeLists, instead of letting CMake determine it automatically.
set(CMAKE_CXX_COMPILER "clang++")
(And yes, I read your original question correct, using this:
-DCMAKE_CXX_COMPILER=clang++
as an additional argument for cmake did not work for me as well, even if it looks like it should behave the same as setting it in CMakeLists.txt)
I tested again with:
clang version 12.0.0
Target: x86_64-pc-windows-msvc
Thread model: posix
And it worked corretly. Seems like it was a problem with clang 11
You're overcomplicating things imo. What about just "cmake .. -T ClangCL && cmake --build ."? Builds fine for me:

And then I change default compiler which is AppleClang to gcc-6.2.0, and then cmake
,all openmp flags find, and configure is fine.

So I am wondering how can I fix that issue, so use itk and openmp as library at the same time.
You're using language/locale-specific double quotes. Most programming languages don't support these, including CMake. Use the "normal" double quotes: "
I am trying to compile my project with CMake which includes the Ceres Solver library. I'm using macOS Sierra with Xcode 8.1 dev tools.
I installed the library with Homebrew (brew install ceres-solver). I downloaded and tested the binary manually (http://ceres-solver.org/building.html#mac-os-x), and that works just fine. But I can't include it in my own project because it can't seem to find Eigen. Here is a complete example:
ceres-test/CMakeLists.txt:
cmake_minimum_required(VERSION 2.8)
project(CeresTest)
find_package(ceres REQUIRED)
add_executable(
TestCeres
src/test_ceres.cpp
)
target_link_libraries(
TestCeres
ceres
)
ceres-test/src/test_ceres.cpp
#include <iostream>
#include "ceres/ceres.h"
int main(int argc, char** argv) {
std::cout << "Works." << std::endl;
return 0;
}
How I compile it:
mkdir build
cd build
cmake ..
make
Full output:
me: ceres-test $ mkdir build
me: ceres-test $ cd build/
cmake
me: build $ cmake ..

I have no idea how to resolve this. None of the solutions I found online helped. CMake seems to be finding the Eigen library just fine, so I'm not sure how to add it in.
On a side note I cannot include "Eigen/Core" directly either, but the tests that I was able to compile do include it and those are fine. I'm not familiar how to deal with these kinds of problems with CMake.
Edit: I can get it to compile if I include it as "eigen3/Eigen/Core" but I can't change the source code for Ceres.
Fixed with
include_directories(${EIGEN_INCLUDE_DIR})
in the CMakeLists....
For my mac mini m1.
I found the eigen library through
brew link --overwrite eigen.
It's located on
/opt/homebrew/Cellar/eigen/3.4.0_1/include/eigen3
I have create a project that uses Cmake and Coin3D libraries: https://github.com/tuxdna/phyloviz

Even though I have specified the include directory using cmake ../ -DCOIN3D_INCLUDE_DIRS=/usr/include/Coin2/, I am getting the fatal error above.
This works fine on Ubuntu 14.04. How can I resolve this?
