Re: [fpc-pascal] Help getting started with FPC
I suggest you look at the FPC/Lazarus Wiki http://wiki.freepascal.org/ for ideas to get you started. It may be easier to start programmng using either the FPC IDE which comes with the FPC package, or the Lazarus IDE which can be used either to produce Windowed GUI applications or simple Pascal console-mode programs. The FPC manuals at http://www.freepascal.org/docs.html contain a lot of information to get you going You will find the FreePascal/Lazarus community very supportive, eg in this mailing list. I have very rarely seen the comment 'RTFM', though people very often offer links to suitable places to get information.

[fpc-pascal] Heaptrc unit is awesome
Hi, I had a suspicion that fpGUI was leaking some memory. After activating Heaptrc I got a bit of a shocker. I needed to log the output to file because it was *very* long. [Yeah I know, nothing to be proud of]. I had 522 memory leaks!! [hiding in shame] But after enabling Heaptrc and 1 hour later, fpGUI is now totally memory leak free! :-) And the best of all - all these cool tools are included with FPC. Great job guys! Feature Request: A minor Feature Request for Heaptrc. Using the log=filename in the environment variable works wonders. I fortunately didn't know that it doesn't clear the file on every run (I'm used to tiOPF log behaviour). So for the first 30 minutes I was constantly staring at the 522 memory leak count (first few lines of the log file) and couldn't figure out why I ain't getting that value any lower! After 30 minutes I was growing frustrated and by pure luck I looked at the log file size between runs and noticed it was growing. Heaptrc keeps _appending_ to the log and I was staring at the result of my first run (over and over). :-) A quick: $ rm ./out.log; ./test fixed the issue. Removing the log before each run. Damn, I wasted a lot of time on that. Could we add extra option in the environment variable setting that clears the log file on each run?

Then I must guess that you either have problems with the paths (strange
characters that mess up the command lines) or something is not installed
properly. What does the about box look like? It should tell what
compilers are installed.
Here's what I wrote:
Program HelloWorld;
begin
print hello
end.
and I'm told
No main program found. Can not build.
I took that code, created a new document in LWP, saved as HW.pas,
fixed the print line
to WriteLn('hello');, hit cmd-R. It runs just fine.
What extension do I need on it?
.p, .pas, .P, .PAS, .dpr should all work in recent versions.
Let me ask:
- Is Free Pascal installed? For the target you use? (If you use an Intel
Mac, you need to change target to Intel unless the PPC compiler is
installed.)
- Is GCC installed? (Comes with Xcode, I don't know if you can download
it separately somewhere. AFAIK FPC needs GCC for linking.)
I am sure this can be solved pretty easily. In all my tests, LWP runs
nicely as long as FPC is installed. I will gladly fix any beginner traps
you find.
