First problem I encoutered is during the installation of the libpng package.
When executing "wget http://sourceforge.net/projects/libpng/ ... z/download
" in the Msys console it doesn't seem to find the file. This I could fix by downloading it myself and moving it to the correct folder.
I can execute "wget http://sourceforge.net/projects/libpng/ ... z/download
" fine here. Sometimes sourceforge is laggy and wget might not download the file. In that case just try again or, as a last resort, just download the file with your browser as you did.
However when I try to perform the ./configure command the error message Zlib not installed gets displayed.
Does anybody have any idea how to overcome this? I've done the Zlib part again twice, there seem to be no errors.
Most of the time, when OpenTTD configure can't find a library you already compiled and installed, it's because you missed the first line of the Setting_up_MSYS
step of the MinGW tutorial. If your /etc/fstab file is missing that additional line then you should reinstall all libraries after adding it.
On a sidenote, but highly related, there seem to be newer version of the packages. Can it be the wiki page is outdated?
The packages at the wiki can be outdated, and will be most of the time. The newest versions of the libraries are usually not required to compile OpenTTD correctly, so I don't update the tutorial whenever a new version comes out. Personally I only update the tutorial when I have to reinstall MinGW again. That allows me to test the new libraries in a "clean" MinGW installation to be sure that no new problems occur. Other people have occassionally updated the packages too, which is fine as long as they test that they work as intended and they don't forget to update all appearances of the library version in the tutorial.
And does anybody know how to copy from the Msys console?
I would've attached the output but I can't seem to find how to do it...
The options of the MSYS are identical to those of the regular Windows console. Just do a right click at the title of the window, select Options, go to the Options tab and enable "QuickEdit mode". After doing this you can select text with the mouse and a right click will allow you to copy the selected text. IIRC there is a way to copy text without enabling QuickEdit, but this is simpler
