libraries

问题 I wrote a program using the point cloud library (PCL). Now I want to use some of cgal's algorithms. I've managed to build a cgal class in isolation (all dependencies working etc.) but when I try and combine the two projects I get unresolved external symbol errors So, what are my options for building a cgal project and accessing it (somehow) from my PCL project? I'd be passing a simple vector to the cgal project so in theory none of the specialist libraries have to interact with each other at

问题 When creating an executable file using PyInstaller, how can I bundle a specific Python interpreter and some library from specific versions? I want to create an executable file from my .py script. My __main__.py downloads some data from a website and transform them, then saves them in a folder as excel files. And here are requirements. Use Python 3.6 For this, I found some related posts but never clear to me. My main .py needs Python3.6 to be executed, and the users of this .exe file won't

问题 I have a programm which imports the request module like this: import urllib from urllib import request ... The programm is running fine in the PyCharm-IDE. But when I run the same code in the console in Linux Ubuntu I get the error: ImportError: cannot import name request Is there a problem with my path? Should I provide more information to solve this problem? According to ImportError on console but not in PyCharm PyCharm is setting the working directory. But when I add this working directory

问题 I'm trying to run CUDA program to generate random numbers by using cuRAND library on Google Colab but I am getting a linker issue. I know,we can fix this by using -lcurand while compiling with nvcc, but as far as I know, we cannot access terminal in colab . I'm using this to generate 2*N random numbers. #include <curand_kernel.h> int status; curandGenerator_t gen; status = curandCreateGenerator(&gen, CURAND_RNG_PSEUDO_MRG32K3A); status |= curandSetPseudoRandomGeneratorSeed(gen, 4294967296ULL

问题 I wanted to use boost::program_options. After I installed boost, I think that I have to build separatly program_options (http://www.boost.org/doc/libs/1_43_0/more/getting_started/windows.html). But I don't know how to do it. I am trying to compile the C:\Program Files\boost\boost_1_42\libs\program_options\example\first.cpp (http://www.boost.org/doc/libs/1_42_0/doc/html/program_options/tutorial.html) but probably due to I didn't build the library I have this error: LINK : fatal error LNK1104:

问题 Is it possible to determine the version of a third party Java library at Runtime? 回答1: Third party Java library means a Jar file, and the Jar file manifest has properties specifically to specify the version of the library. Beware: Not all Jar files actually specify the version, even though they should . Built-in Java way to read that information is to use reflection, but you need to know some class in the library to query. Doesn't really matter which class/interface. Example public class Test

问题 I am trying to include a Yocto recipe in the image which I wrote for static library. Created recipes-test/static folder in my own layer .
