A Computer Person Journey
After succesfully setting up IUP lib reference in codeblocks its time to test some IUP coding style. Download source code below.
In main.c file, we create some buttons and attach event handler to it. I modify it from IUP hello world sample to show how we access other controls from a event handler that only has reference to the control sending the event.
IUP is a cross platform GUI library. Last time tried to figure out how to compile an IUP hello world program using codeblocks IDE. After some searching on internet finally managed to compile it. Here is the linker setting used.

Wee is a gtk based editor for euphoria. There is an instruction on euphoria wiki and we will follow that.
Euphoria still have its own editor written in euphoria called edx.
To call edx one must type eui <path to edx.ex> which is too much to type 🙂
There is a way on euphoria to bind an ex script to interpreter to create an executable using eubind. Here is how i do it on linux.

Today im installing it on linux mint. Its have been a long time and now euphoria version is at 4.1.0 and maintained by openeuphoria.org.
Here is how i install euphoria.

On ubuntu/mint/debian do as follow :
apt-get install ruby-dev
apt-get install libsqlite3-dev
Dont forget to execute as root.
After that we can execute gem install sqlite3.
Thats all … Bye.
Happy chinesse new year 2570 !
jEdit is a java based editor for programmer, so it will run on many platform : windows, linux, mac.
First download jEdit installer from the web.
I choose to download java based installer and start it on my windows based laptop.
After a while a dialog will show up.
Debian based linux like ubuntu and linux mint can use these steps to install wxWidgets.
$ sudo apt-get install build-essential
If we do not have a C++ compiler yet, we install the build-essential package.
I think this is an meta package that install the actual packages for programming task.
$ sudo apt-get install libwxgtk3.0-dev
This installs the wxWidgets package.
To test it with minimal console application that emit some text we will create console.cpp and compile it.
#include <wx/wx.h>
int main(int argc, char **argv)
{
wxPuts(wxT(“A wxWidgets console application”));
}
