How to install djgpp




















Don't modify it unless a package tells you to do so! Most DJGPP programs support both styles of slashes; however, being Unix ports, they might sometimes support forward slashes better. When in doubt, try forward slashes, like the example. Your distribution probably contains lots of other zips when I wrote this, there were separate zips! Most of them have documentation explaining about themselves, so go poking around and see what you've got.

Everyone should install these, whether they need them or not. Because it may not be obvious that you need it, but they're commonly referred to on the newsgroup. Also, note that the version you have may have newer version numbers in the file name; just use the newer file if that's the case. This is the basic runtime and development package, and includes such things as the include files, C libraries, standard utilities, FPU emulator, and timezone definition files.

Before you ask anyone else, read the FAQ! Run "info" to start the online document system. It also includes the pre-processor, which many other languages use, and the GNU compiler support library, which nearly all programs will need. You'll need these for all languages. Not everyone uses it, but it's strongly recommended. As a result, people who work with Mingw32 tend to use all kinds of different and subtly incompatible versions of shells, Make, etc. Of course, if you don't mind developing with a minimal set of tools, this might not be a serious consideration for you.

Microsoft tends to rearrange its site frequently, and changes the SDK location in the process. You might need to apply the patches manually if the patch utility fails.

Likewise, you should make sure the compiler looks in the correct directories for libraries and the crt0. When in doubt, add -v to the compiler's command line to see which directories it searches and in which order, and what libraries does it link in. One specific problems with conflicting headers is with the header function.

I'm also told that the stdio. Sections 1 and 5 are special types of sections that will be discussed later. There is no space before the colon, only after it. After this, there is a list of dependencies. Dependencies are names of files that will cause the command on the next line to be run if they have been modified. This speeds up recompilation because it only recompiles the files that need to be recompiled because their source code has changed.

The second line in a normal section is a command to be executed on the command line if Make determines that one of the two conditions for recompilation has been met. The line must start with a Tab character and cannot have any spaces before or after it.

The command to be executed on the command line is immediately after the Tab character. The dependencies are "functions. These two files are the C source and header files that are used to compile the "functions. The sole dependency is "main. Remember, the "-lm" part links to the C Math library and is unnecessary if you are not using the C Math library. The dependencies are "main. Make will recursively check the dependencies of both of these dependencies to see if these object files need to be recompiled before linking them into the "prog.

It will perform this recursive check by going into Sections 3 and 4 and checking their dependencies and running their commands if necessary. Since there is no "all" filename and none of the sections produce this file, it will always go on to the dependency of "prog. It will always be run when "make clean" is run on the command line. This command will remove all of the ". To run Make on the command line to make everything but not run "make clean" , type "make" and hit Enter.

Executing Make with no arguments is equivalent to running "make all" on the command line. Running Make a second time will display "make. Running "make clean" will delete all of the ".
