It's not like an IDE, but once you get used to it it's just as simple.</p> <p>Say I have two files, program.cpp and library.cpp. Here's my makefile:<br /> <pre><code>RunThis.exe : program.o library.o gcc -o $@ $^ # $@ means target (RunThis.exe) # $^ means dependencies (program.o library.o) # You could also use this: # gcc RunThis.exe : program.o library.o program.o: program.cpp gcc -c $@ $^ library.o: library.cpp gcc -c $@ $^</code></pre> <p>Here's a simpler one:</p> <pre><code>RunThis.exe: program.cpp library.cpp gcc -o RunThis.exe program.cpp library.cpp</code></pre> <p>The benefit of the first is that if you change one file, the others don't need to be recompiled. Make sure you use TAB characters to indent, spaces will not work. Make is very picky. </p> http://pnotepad.org/forums/topic/322#post-1157 Mon, 21 Jan 2008 12:52:26 +0000 simon 1157@http://pnotepad.org/forums/ <p>You can use anything from a simple batch file to a script you write that parses the .pnproj file and runs the correct tool for each file. You might also google the following which are all good tools you can run to build multiple files:</p> <p>make<br /> NAnt<br /> Ant<br /> cmake </p> http://pnotepad.org/forums/topic/322#post-1155 Thu, 17 Jan 2008 05:22:48 +0000 superjacent 1155@http://pnotepad.org/forums/ <p>How is that done? </p> http://pnotepad.org/forums/topic/322#post-1154 Thu, 17 Jan 2008 04:18:05 +0000 qpsoft 1154@http://pnotepad.org/forums/ <p>use makefile. </p> http://pnotepad.org/forums/topic/322#post-1153 Thu, 17 Jan 2008 00:48:02 +0000 superjacent 1153@http://pnotepad.org/forums/ <p>How somebody can help. I'm learning C++ and have been using Programmer's Notepad to compile single file programs. Now I've moved onto to multiple file programs. How do I link &#38; compile multiple (.cpp) files from within Programmer's Notepad?</p> <p>Any advice would be appreciated. </p>
