Fixed! "Undefined reference to.." errors
 

FYI,

I had been experiencing "undefined reference to" problems in one of the programs I had been writing. I even tried to use the "-l" option when using gcc, but no luck.

My fix? I changed the extension from ".cpp" to ".c". I have no clue why that worked, but it did...

If anyone has an idea how or why that worked, feel free to post.

I'm moving this to programming.. but I probably know why you had problems.


GCC decides what type of file you have based on the file extension. ".cpp" is a C++ file and ".c" is a C file. The problem probably was a result of you compiling a C++ file with gcc without passing the -lstdc++ option. This can be avoided by compiling C++ programs with the g++ executable instead.
