Only source code files contained within the same project - found beneath the Sources branch - are linked together.

That’s probably why Code::Blocks names the first (and, often, only) project source code file main.c. Click Dependencies and add the name of the library (including its relative path) to External dependency files. Q: Code::Blocks does not force relink if the library is changed? A: Open Project->Properties->Build targets (tab) and select the executable. However, each code block (also called a 'code chunk') is executed as a separate Stata session. And very often the code illustrated in later blocks will depend in some way on code in the previous blocks. Most documents have alternating blocks of code, output, and explanatory text.

Welcome to, a friendly and active Linux Community. Try compiling it as gcc Main.c Person.c -o MyProgram. The problem is probably occurring because you're compiling only Main.c when you need to be compiling Main.c and Person.c at the same time.

Be sure to compile and link all of your source files using a project in your IDE or using the correct command-line arguments.ġ. If you don't want to take the time to implement these functions yet, you need to at least add empty stubs for them. Your main.cpp file declares several functions which are not later defined. More often it is useful to create a projectso that Code::Blocks can manage the entire build. Save your file with the correct file extension (*.cor *.cpp). If you do not specify the return type the compiler will infer an int return type.Ĭode::Blocks checks the file extension for individual files before allowing them to be compiled. Also C98 allows the use of default int return types.

Undefined reference to printf code blocksĪlso the problem was the OP misspelled printf() C and C++ are case sensitive, Printf() is not the same as printf().
