[MinGW] Fix [Linker error] undefined reference to '_imp__curl_easy_init'

Recently, I found some error during the compiling progress of my curl program with Code::Blocks.
The error keep showing in Code::Blocks like this:

[Linker error] undefined reference to `_imp__curl_easy_init'

I try to repair the Linker settings and Search directories but found out that there’s nothing wrong with it.

It turns out the MinGW version has been modified to Win64 version last time when I was trying to deal with some W64 programs few days ago.

I found that the MinGW download directly from the official website cannot be used in Code::Block properly.

Hence, I use tdm-gcc instead.

Here’s the procedure to fix the curl reference error.

Download the tdm32 bundle from:
http://tdm-gcc.tdragon.net/

Install MinGW/TDM(32-bit) by just clicking Next in the next few steps

After the installation process, the MinGW will be installed under C:\TDM-GCC-32

Open your Code::Blocks program and go to Settings>Compiler
enter image description here

Change the setting as followed

Now the reference error message has been fixed.

Make sure the MinGW, curl and OpenSSL has been installed in Win32 version!
