Simple installation

[jimihendrix]

Hi, Im new to the mac
Ive had to write a program for both windows/mac (normally I code in c++) but since this crossplatform I thought something like lazarus would suit me better, Yesterday I finished the windows program (first time Ive used pascal since 1985  but it was pretty painless )
Anyways I cant seem to install lazarus for my mac powerpc (*), is there a no brains required method to install it i.e. written for someone who's never used a mac before. My other option is to write the app with Xcode (which is installed) in either c/objective c. but that seems a shame since Ive already written it in lazarus with windows 

(*)I get the message bad CPU type in executable

cheers

I get the message bad CPU type in executable

Did you download the correct .dmg?

[jimihendrix]

thanks Leledumbo for replying
yes I did, the powerpc one
but Ive solved it now

note to other newbies -
ignore the files from http://sourceforge.net/projects/lazarus/files/ which use fpc 2.2
and used the ones from the http://www.hu.freepascal.org/lazarus/ which use fpc 2.4

A couple of new questions
1/ The scrolling of the html is very jerky, I just wanna display some text in the html page (but require bold,italics on some words) thus cant use a memo control (a richmemo control would be nice I think) also I require this to be printed. Have I set this up wrong perhaps? (it scrolls nice on the windows lazarus version)

2/ the *.app file is huge ~16,000 kb for comparison on windows its 1,500 kb. FWIW with a staticlly linked c++ windows the *.exe is only 50kb!!!

I know pascal does generate larger files but 320x larger is a bit ridiculous   

cheers guys

Hi, jimihendrix

1. You should use THtml components, I use them in everydays work and they are good and fast.

2. http://www.lazarus.freepascal.org/index.php/topic,9066.0.html

Remember to turn off the debug info when you are making a release version. File size should drop to ~ 2MB

cheers mate

1/ yes just installed it (nice and simple, gotta love it)
and it works, much much nicer 
Works so good that Im wondering if I should go back and add it to the windows version

there is a small bug though, if you press ther up/down arrows then the scrollbar moves but the actual html doesnt (I can live with that though) pageup/down work and draging the scrollbar also.

2/ I believe I am doing strip (which makes a huge difference with the size of the windows exe) but from what I can see makes bugger all difference to the mac *.app

[Wodzu]

Glad you like it

As goes for the 2.
Go to the Menu -> Project\Project Options\Compiler Options\Linking and turn on Link Smart (-XX) and Strip Symbols From Executable (-Xs)

Hope that it helps.

Edit: If there is a bug in THtml, please report it in the Bugtracker.

Ta Wodzu

1/ doesnt seem to help, still a huge *.app size, setting those on windows makes the *.exe like 15% size so big help there
Perhaps theyre not implemented with the mac or Im doing it wrong (cant see how though)

2/ Submited to bugtracker (hopefully in the right place)

another minor question
3/
my app is reading a file from the same directory as the *.app
whats the standard way
LoadFromFile( 'filename' );
or
LoadFromFile( './filename' );

the reason I ask is cause when I run the app from lazarus it opens a different file to when I click on the *.app in Finder

cheers guys

[jimihendrix]

WRT *.app size

hello_world standard size = 18mb
 Link Smart (-XX) and Strip Symbols From Executable (-Xs) size = 13.9mb

so not a massive saving like the windows version has

But Ive run into a worse issue

apparently my app that Ive built doesnt run on a macintel, is it possible to create an macintel *.app on my powerpc?
or am I screwed 
If so what are the options?

[Wodzu]

jimi I am sorry I can't help you with Mac cause I've never used it.

I am sure you can go down with the file size, though. Have you turned on level 3 optimization too?

I really hope you solve your problem with Mac. Maybe it is worth to start another thread for this.

what you need it to cross-compile LCL for Intel target.

Here's the explanation how to cross compile from Intel to PowerPC.
http://wiki.freepascal.org/Carbon_Interface#Getting_PowerPC_units

Cross-compiling from PowerPC to Intel should work in the similar way.
Try to specify target cpu as "i386".

[jimihendrix]

yes I saw that skalogryz, I did try it but it didnt work before (it gave me errors), Ill give it another go though

@Wodzu I dont think u can change the -O1,2,3, etc, theres a lot less options under the mac, than there is with windows/unix

cheers guys

what kind of errors?

[jimihendrix]

well if I go
Environment -> Options

and try to change compiler path
to anything thats not /usr/local/bin/ppcppc
eg
/usr/local/bin/ppc386

and press OK I get the message
"the compiler file /usr/local/bin/ppc386 is not an executable"

[Wodzu]

@Wodzu I dont think u can change the -O1,2,3, etc, theres a lot less options under the mac, than there is with windows/unix

Sorry to misguide you than, I've assumed that the options will be the same. 

[skalogryz]

"the compiler file /usr/local/bin/ppc386 is not an executable"

what fpc version are you using? where from did you download the fpc from (was it lazarus download page)?
