As per tip given, I have made a thread about how to add a file to a project in bloodshed. I'm using version 220.127.116.11
Here's the original suggestion from the thread:
Sorry, I don't know anything about your compiler. If you are getting a linker error, that means Bloodshed can't find one of the files. I would read up on how to add files to a project in Bloodshed. For instance, I can have a file open in my compiler(MS VC++6) along with the other files, and it doesn't mean it's part of the project. I have to specifically insert any new file I create into the project.
If you can't figure out how to add files to a project, post a new thread titled something like:
"How the !#$@!#$ can I add files to a project with Bloodshed"
There should be many people on this forum that can help you with that.
