How can I add a path to a Makefile?

Asked 2022-Mar-22 at 19:41

In C++, I have a library path I know how include when building with a CMakeLists.txt file but I don't know how to include it when building with a Makefile.

I tried applying the solution asked and answered here but it didn't work. The contents of the Makefile is below. The library's name is "NumCpp". The full path to this library on my computer is C:\Users\ooo\tor\Robot\rainbow\NumCpp\include\.
In the .cc file I am including the library as #include "NumCpp.hpp"

This is the CMakeLists.txt file. This would include and compile the NumCpp library if you ran this in the directory containing NumCpp. I don't know if it is helpful to show this, but I know I can include the library this way.

QUESTION

How to build header only C++ library within Bazel workspace?

Asked 2022-Feb-07 at 19:50

I'm working on a C++ project and I need Numpy like arrays and functionalities in C++. I found some alternatives like xtensor, NumCpp etc. These are header only libraries. The problem is I'm experimenting with Bazel for the first time so, I don't have any idea about how do I add header only library to Bazel workspace. There are some suggestions like genrule-environment, rules-foreign-cc suggested on other questions around Bazel. I've added http_archive to WORKSPACE file, but I'm not sure what to add in BUILD file.

Answered 2022-Feb-07 at 19:50

For simple things like header-only libraries, I would write BUILD files yourself, without using rules_foreign_cc. Just write a cc_library with no srcs. Something like this:

All of the definitions in 3DObjectDescription.cpp are missing return types in their signatures.

Simply update their signatures to include the void return type. The definition for Object3D::translation should read

Asked 2021-Feb-23 at 17:54

When I described prototypes of functions in header file and implemented functions at MoveMatrix.cpp, I got error: compiler says "error: redifinition of nc::NdArray translate(float, float, float)", although I hadnt described or even mention this functions int other files besides MoveMatrix.h. I have got error from 4 line of MoveMatrix.cpp!

This is MoveMatrix.h

The suffixed {} means that the functions are defined in the header. Thus the one definition rule is violated, and compilation will fail. Remove them to convert the statements to forward declarations.

Rebuilding a C++ program with OpenCV on a VM

Asked 2020-Sep-19 at 01:47

I need to switch from an ubuntu 20.04 to a Windows 7 workstation.

I'm writing a program for Raspberry PI that needs pthread, so I need a linux test environment.

I installed an ubuntu 20.04 VM and reinstalled all the libraries used in my program :

OpenCV 4.2
Libtorch
NumCpp

Here is my CMakeLists.txt :

I finally managed to make it work, thanks to @squareskittles : I needed to uninstall OpenCV, and rebuild it from source to the good version, with C++14 standard.

If you have linking problems related to OpenCV when building, uninstall OpenCV and build it yourself :

How to solve GTest and LibTorch linkage conflict

Asked 2020-Jul-02 at 15:21

This question follows my precedent one.

I'm writing a C++ program with OpenCV, Torch and NumCpp. The program compiles and works fine for now, but I need to write unit tests.

I've followed google's tutorial to build GTest and GMock inside my project, but it fails. When I don't link Torch libraries, that works.

Error when linking GTest + Torch :

PyTorch uses -D_GLIBCXX_USE_CXX11_ABI=0 compilation flag (which should be a criminal offense in 2020 IMNSHO). You need to compile all of the code, including gtest, with this flag.

This flag is in TORCH_CXX_FLAGS, however gtest uses its own CMakeLists.txt with its own set of flags. You should add it manually. The easiest way is probably with add_compile_definitions(_GLIBCXX_USE_CXX11_ABI=0) somewhere near the top of CMakeLists.txt.
