Compilation error #2

Closed sunwooOh closed 6 years ago

sunwooOh commented 7 years ago

Hi nwojke,

I tried to compile the codes but when I run make, I get this error:

mkdir -p /home/username/Projects/test/mcf-tracker/build/mcf cd /home/username/Projects/test/mcf-tracker/build/mcf && \ make -f /home/username/Projects/test/mcf-tracker/external/mcf/Makefile-external pybind11 make[1]: Entering directory /home/username/Projects/test/mcf-tracker/build/mcf' make[1]: /home/username/Projects/test/mcf-tracker/external/mcf/Makefile-external: No such file or directory make[1]: *** No rule to make target/home/username/Projects/test/mcf-tracker/external/mcf/Makefile-external'. Stop. make[1]: Leaving directory `/home/username/Projects/test/mcf-tracker/build/mcf' make: *** [mcf.so] Error 2

Assuming that above error was raised because of the lack of mcf and pymotutils, so I git-cloned them to build directory. And then, tried to compile mcf. However, running following commands (as given in the README of mcf git repository) gives another error.

Commands: git clone https://github.com/nwojke/mcf.git (to mcf/external/ directory) mkdir mcf/build cd mcf/build and

make -f ../Makefile.external pybind11
cmake -DCMAKE_BUILD_TYPE=RELEASE -DMCF_BUILD_PYTHON=ON -DMCF_BUILD_STATIC=ON ..

Raised error:

CMake Error at build/external-install/share/cmake/pybind11/pybind11Tools.cmake:29 (message): Unsupported compiler -- pybind11 requires C++11 support! Call Stack (most recent call first): build/external-install/share/cmake/pybind11/pybind11Config.cmake:107 (select_cxx_standard) CMakeLists.txt:49 (find_package)

Can you help me with solving this problem? My settings are:

Thank you.

Hi,

looks like the README is outdated. Can you run

git init submodules recursive

on the repostiory root? This should clone the necessary submodules in external. This should fix the initial error.

If you still get the error when building pybind11, the compiler might be outdated. The library requires a C++11 compiler, I am not sure if G++ 4.9 has already -std=c++11 or if it is -std=c++0x. Do you have any chance to update to at least version 5?

I will update the README when I find more time again.
