To compile one program from multiple source code files, use gcc -o outputfile file1. To compile multiple programs at once with multiple source code files, use gcc -c file1. Run your newly-compiled program. Method 2. This is an easy-to-install version of GCC for Windows.
Use the following steps to download MinGW:. Click the green button that says Download. Wait for the installer to download automatically. Install MinGW.
Use the following steps to install MinGW: Double-click mingw-get-setup. Click Install. Click Continue. Select which compilers to install. At the minimum, choose Basic Setup on the left panel, then place check marks next to all of the listed compilers in the right main panel.
More advanced users can choose All Packages and select additional compilers. Right-click each package and click Mark for Installation. The Basic Setup has about 7 packages listed in the box at the top. Right-click each one of them or just the ones you want and click Mark for Installation. This adds an icon with an arrow next to each one and marks it for installation.
Install the selected packages. It may take your computer several minutes to install all packages. Use the following steps to install the packages that are marked for installation. Click the Installation menu in the upper-left corner. Click Apply Changes. Click Apply. Click Close once the installation is done. Add the path to MinGW to system environment variables. Use the following steps to add the path to MinGW to system environtment variables: Type environment in the search bar next to the Start menu.
Click Edit the system environment variables in the search results. Click Environment Variables Select the Path variable. Click OK , and then OK again. Click the one remaining OK button to close the window. Running make without argument starts the target " all " in the makefile. A makefile consists of a set of rules. A rule consists of 3 parts: a target, a list of pre-requisites and a command, as follows:.
The target and pre-requisites are separated by a colon :. The command must be preceded by a tab NOT spaces. When make is asked to evaluate a rule, it begins by finding the files in the prerequisites.
If any of the prerequisites has an associated rule, make attempts to update those first. In the above example, the rule " all " has a pre-requisite " hello. The rule " hello. Again, it does not exist, so make looks for a rule to create it.
It runs the command " gcc -c hello. Finally, the rule " all " does nothing. More importantly, if the pre-requisite is not newer than than target, the command will not be run. In other words, the command will be run only if the target is out-dated compared with its pre-requisite. For example, if we re-run the make command:.
You can also specify the target to be made in the make command. For example, the target " clean " removes the " hello. You can then run the make without target, which is the same as " make all ". A comment begins with a and lasts till the end of the line.
The rules are usually organized in such as way the more general rules come first. The overall rule is often name " all ", which is the default target for make. A target that does not represent a file is called a phony target. For example, the " clean " in the above example, which is just a label for a command. If the target is a file, it will be checked against its pre-requisite for out-of-date-ness. Phony target is always out-of-date and its command will be run.
The standard phony targets are: all , clean , install. Single character variables do not need the parentheses. You can also use vpath lowercase to be more precise about the file type and its search directory.
Make comes with a huge set of implicit pattern rules. You can list all the rule via --print-data-base option. Make is actually quite complex, and can be considered as a programming language by itself!! GNU Make: an automation tool for compiling and building applications. GNU Binutils: a suite of binary utility tools, including linker and assembler. GNU Bison: a parser generator similar to lex and yacc. Cygwin is huge and includes most of the Unix tools and utilities.

EDIT: Rup says it best in his comment to another answer: [ Improve this answer. Community Bot 1 1 1 silver badge. Evan Teran Evan Teran Neil: from what I can tell, gcc does consider a. The following works just fine: gcc test. C -o test. Evan Yes, of course it does. That does not mean that you should ever use it though, as it will cause terrible portability problems, as do all case-sensitive file names. This causes no problems, and is guaranteed to work on all common operating systems.
Alexandre C. Can you explain why? Please give the reason too and the answer is not complete. I don't know is this the standard answer look like? Praveen S Praveen S It's a bit more complicated than that, as in the other answers here.
