Cross-platforming C++ functions to APL

由 旧巷老猫 提交于 2020-01-05 08:37:11
问题 I am currently writing C++ programs for APL. Up to now, what I've been doing is creating a function in APL, which runs the command prompt and calls the executable, with input and output files it creates as parameters and in turn, the C++ executable is programmed to open the input file, read the input and store the output in the output file, which is fetched by the APL function and stored in one or more variables. The problem with this method is that, when I use simpler functions which will be

How to hold data structures in memory G-wan with Java / Scala

问题 I am looking at Gwan as a higher performance way to run our Scala application. Our use-case involves keeping a good amount of data in memory using Scala data structures. This is a bit more complex than a simple hashmap so I would want to avoid trying to wedge it into the K/V store that comes with Gwan. Also there are a number of C-libraries that would be great to interface with. Curious what the process of using a third party C-library with a Scala app on Gwan would be. Thanks! 回答1: keeping a

问题 To communicate to a ROS2 based publisher and a RTI Connext based subscriber, both of them need to have a compatible QoS settings. I am using RTI Connector for python and using the XML Application Creation to run the subscriber. I run a talker_py in ROS2 which has a default QoS and subscribe to these messages in RTI Connext Pro. The ROS2 IDL is looks like this : { module msg { module dds_ { struct String_ { String data_; }; }; }; }; I use the rtiddsgen utility tool to convert it into a XML

C: cross-platform RS-232 serial library? [closed]

由 ↘锁芯ラ 提交于 2019-11-28 18:42:50
I am looking for an open source cross-platform library for working with the serial port in C, something along the lines of the awesome PySerial library (unfortunately I have to use C for this application). I have only found this one: http://www.teuniz.net/RS-232/ , and that doesn't seem to have mention OS X compatibility. You would think that a cross-platform C library for serial ports is something that would have existed for 20 years already, but as of 2013 there still wasn't one, so I created libserialport . It is tested on Windows, Mac OS X, Linux (including Android), BSD and will probably
