I am trying to compile my c++ project (working with g++ with boost) with clang. I have successfully compile boost-libraries (1.53) with clang tool-chain. I am using CMake to compile my project, compilation is failing with following error.
In file included from /home/dilawar/Works/hpc21/bliff/BlifParserAndPartitioner/src/expression_graph.h:21:
/usr/local/include/boost/graph/graph_traits.hpp:14:10: fatal error: 'iterator' file not found
#include <iterator>

1 error generated.
I am passing -stdlib=libc++ to compiler. I am not sure which package I should install (ubuntu) to install libc++. I have clang and llvm installed on my machine.
Do I have to download and compile libc++ or it is installed automatically when one install clang?
When you pass -stdlib=libc++ the clang driver looks for header files in a different
directory w.r.t. when you don't pass the flag. You have to install libc++ separately. The libc++ webpage (http://libcxx.llvm.org/) has some details on how to install libc++ using CMake.

I want to use specific version of CMake 3.19.0 for Ubuntu 14.04 (32-bits) without installing CMake (use only binaries).
I tried to build CMake 3.19.0 on my test machine. It builded and installed successfully. In install_manifest.txt I see lot of files that were installed on my test system.
So, I tried to copy only installed binaries from /usr/local/bin/ (this is default path where CMake binaries were installed) and paste it to another machine that doesn't know about CMake. I paste 3 binaries: cmake, ctest, cpack to /usr/local/bin/.
If I run which cmake it shows path:
/usr/local/bin/cmake
If I run cmake --verison it shows:
CMake Error: Could not find CMAKE_ROOT !!!
CMake has most likely not been installed correctly.
Modules directory not found in
/usr/local/share/cmake-3.19
cmake version 3.19.0
CMake suite maintained and supported by Kitware (kitware.com/cmake).
It looks like CMake needs some modules that I haven't copied yet. I tried to build my cpp project and it shows me:
CMake Error: Could not find CMAKE_ROOT !!!
CMake has most likely not been installed correctly.
Modules directory not found in
/usr/local/share/cmake-3.19
CMake Error: Error executing cmake::LoadCache(). Aborting.
What are the minimum required modules needed for stable building? And where I should copy it?
Just copied builded Modules and Templates directories from cmake-3.19.0 build directory to /usr/local/share/cmake-3.19
I am writing a CMakeLists.txt to compile and install my programs. I have following error with the below install() command. I need to install a symbolic link (additionally to the library so file) for the created library.
CMake Error at CMakeLists.txt:96 (install): install TARGETS given
unknown argument "NAMELINK_COMPONENT".

I am following the instructions given in the CMake documentation (https://cmake.org/cmake/help/v3.13/command/install.html#). is this because of cmake version in my PC or syntax error ?
please help.
You need to have same version of CMake (v3.13) or newer.
I am trying to run pip3 install face_recognition. But it gives below problem for cmake.
Building for: NMake Makefiles
CMake Error in CMakeLists.txt:
Generator
NMake Makefiles
does not support platform specification, but platform
x64
was specified.
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
pip3 version is 9.03, Python 3.7 and cmake 3.12.0-rc3. I don't have Visual studio. I don't have admin rights on my PC. Hence I downloaded the all the above packages, extracted and added their bin dir in path. Similar way I have installed MinGW and added its bin directory in path. Nothing is working. Couple of forums talk about removing CMakeCache.txt. I am struggling to find CMakeCache.txt. I think pip command is downloading the package, extracting in temp directory and compiling it. When compilation fails it delete the extracted content. Not sure. Please help
After carefully studying a logs, I realized it's Dlib installation a giving problem. After lots of search, I got the url https://www.learnopencv.com/install-opencv-3-and-dlib-on-windows-python-only. It suggest to use Anaconda. I installed the Anaconda and followed the instruction from article and discussions. It worked perfectly for me.
I followed all the instructions for setting up gmp with cygwin,
./configure make make install and make check.
The libgmp.a is in the path C:/C++/gmp-6.1.2/.libs
I'm using this command to compile with g++
g++ -L/C:/C++/gmp-6.1.2/.libs -I/C:/C++/gmp-6.1.2 C:/foo/foo.cpp -lgmp
I get an error message that says : could not find -lgmp
What am i missing?
Why not install the gmp from the cygwin distribution?
I have cmake 3.2.3 installed via pacman. I get an error when I try to use it from a msys64 shell:
$ cmake -G "MSYS Makefiles" ..
CMake Error: Could not create named generator MSYS Makefiles
cmake --help does not list it as an available generator.
I do see there is an MSYS.cmake in /usr/share/cmake-3.2.3/Modules/Platform.
What am I missing?
Instead of installing the cmake package, I think you need to install mingw-w64-i686-cmake (or the 64-bit version mingw-w64-x86_64-cmake).
I got the exact same message when trying to run cmake in the MSYS shell. Use a MinGW Shell (for instance MinGW-w64 Win64 Shell) instead.
If you compile native Windows binaries on Linux with MinGW
The MinGW and MSYS generators are only available on Windows based distributions. See #ifdef in cmake.cxx:
#if defined(_WIN32) && !defined(__CYGWIN__)
If you're cross-compiling use one of the available MinGW toolchains. See e.g. "How to use MinGW to cross compile software for Windows" chapter in CMake's wiki.
If you compile Windows binaries on Windows with MinGW
On my Windows PC I only have one CMake installation (the normal MSI Windows Installer with CMake directory added to PATH environment), which works from standard CMD shells and from my MSYS shells.
So in this case there is no need to install a special MinGW version of CMake (like e.g. for CygWin).
But I've rebuild CMake from source with MinGW-w64 several times lately to test some performance optimizations of cmake.exe and it did not work out-of-the-box. To work around the linker errors I've added -DCMAKE_EXE_LINKER_FLAGS="-Wl,--allow-multiple-definition" like recommended here and the resulting cmake.exe still supports the "MSYS Makefiles" generator.
So yes, there is - as you have commented - most probably something wrong with the pacman build.
I guess the pacman build is just broken, so I've resolved this issue by installing the Windows version of CMake from cmake.org with the msi installer.
