This article describes how to create a simple static library using C++. A static library is a collection of object files that are linked with and copied into a target application at compile time. The resulting executable contains all the object code from the static library, so it can be executed independently of the library.
Static library Let’s start by creating a simple square class:
// src/square.h #ifndef SQUARE_H #define SQUARE_H class square { private: double length; public: square(double length); double area(); }; #endif and its corresponding implementation:
This article describes how to create a simple shared library using C++. A shared library is a collection of object files that are linked with and loaded into a target application at runtime. The resulting executable contains only the object code that is needed to load the shared library, for this reason, the library has to be distributed with the executable.
Shared library Let’s start by creating a simple sum.c program using C.
Run Pentaho Data Integration on Mac OSX. The following procedure works with all the latest OSX versions.
My local configuration OSX Mojave OpenJDK 11 Procedure Download pdi-ce-8.1.0.0-365.zip from https://sourceforge.net/projects/pentaho/ Unzip it Using the terminal, cd into the unzipped directory Run the application open Data\ Integration.app If you get the following error:
LSOpenURLsWithRole() failed with error -10810 for the file Data Integration.app then run the following command (it is permissions related):
Part of my work as a Web/UNIX developer includes maintenance and development of tools using Oracle’s Pro*C.
In text interfaces, VIM is a pretty decent tool for creating source code and their companion make files. If you created the right make file, compiling is also a breeze. However things get kind of tricky when you have to debug. Oh my! This can be a difficult task. Many may say that there’s nothing like gdb, but come on guys, even you can’t deny the beauty of a visual debugger.
Installing PHP/MongoDB extension is a two steps task on OSX:
Install the autoconf tool required for compiling the extension Install the Mongo extension You have to install autoconf in order to avoid the following error:
Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF environment variable. Then, rerun this script. ERROR: `phpize’ failed Enough talk, hands on work…
Step 1. Install the autoconf tool Download the latest source version:
A Finder alias is a special kind of shortcut or link to a folder. You can place this alias anywhere, being the Desktop a common place. You can even create an alias from a shared folder on a server.
To create an alias:
Open Finder and look for the folder you want to create an alias for. Press Option + Command while you click and drag the folder to the desktop.
Learning how to create a Makefile is one of those tasks every C/C++ programmer has to do. Since there are many good make tutorials on the web, I’m only going to share a simplistic makefile that you can use for your projects.

Show User ~/Library in OS X Lion Launch Terminal from Spotlight or Launchpad > Utilities, and enter the following command to show the directory:
``
chflags nohidden ~/Library/ The users Library folder will immediately become visible. Reverting this back to the standard Lion setting is simple too:
Hide User ~/Library in OS X Lion (default setting) This returns to the default setting of hiding the user Library directory:
``
