Hi,
I recently retrieved fpc-pascal 2.0.2a from the Lazarus download site together with Lazarus 0.9.16.
System: AMD64 1 Gb mem. sufficient disk space, Linux 2.6.17-1.2139_FC5. My problems:
1.
Starting "fp" freezes the terminal window. When I do "fp &", the window is accessible but the first keystroke stops fp.
"fpc hello" (as said in the manual) doesn't work (neither from root nor from a user-terminal).
"fpc helloworld" when in the helloworld directory works.
2. (I don't know if this is the right place)
Installing Lazarus gives:
"error: Failed dependencies:libgdk_pixbuf.so.2 is needed by lazarus-0.9.16-0.i386"
However "locate libgdk_pixbuf.so.2" gives:
"/usr/lib64/libgdk_pixbuf.so.2
/usr/lib64/libgdk_pixbuf.so.2.0.0"
I did this with the fpc retrieved from the lazarus site. TAfter removing fpc completely I installed fpc 2.0.2-4.fc5 (Fedora site) which of course caused lazarus to refuse to install. My conclusions:
1. fpc will compile programs on a 64-bit system.
2. The IDE is not tuned to a 64-bit system (strange however for a fedora 64-bit system)
3. The Lazarus rpm is not rigged for the 64-bit fpc. My questions:
1. Can programs compiled on a 64-bit system run on a 32-bit system (or is there a setting for it).
2. Does anybody have a solution as I'm a Pascal programmer from way back (started in 1985 with Borland Pascal for the Amstrad (does anybody remember this machine??)) and it is my opinion that Pascal is one of the best designed programming languages and fpc (I have tested it last year on a 32-bit system) a very good superset of the good old BPC 7.0. Therefore I would like to use it with Lazarus as a (sub?)set of Delphi. Thanks in advance

Hi,

I wanted to install fpc/laz on a friend's AMD64 myself a fey days ago in order to show the "power of FPC" but I realized quickly that AMD64 is a different "animal".

I can not answer any of your questions as I am not a developer.

However I can say that there are as many platform to support as there are developers! It seems that their big effort right now is towards GTK-2 as the older (GTK-1) will soon not be supplied on some distributions. I understand this is a big priority for them!

Now for AMD 64: I think that there are some developers working on this. The progress may not be as fast as one would like it to be, but we have to understand that it is a lot of work for the very small group of developers. If AMD64 becomes more popular, then the developers will quickly want to use it too and quickly we will have something that works.

Now for pascal: there are endless discussions on this list about that. The conclusions are always the same:

Pascal will not die because we do not want that to die...

Cheers

Alain

p.s. If you find out what to do install lazarus on AMD 64, please let us know.

Question - 1:

Once I have installed the module: fpc-2.0.2.x86_64-linux.tar then does that means that I use the "regular" source code: fpc-2.0.2.source.tar.gz in order to recompile FPC or to compile lazarus?

Question - 2 :

Is there a special Lazarus version for AMD64 ? Does it work on AMD64 ?

I think that you need to install fpc-2.0.2.x86_64-linux.tar and then use that to compile lazarus source code. Just download a package with Lazarus source code and do a:

make clean all

If this doesn´t work, then report what problems you had.

Question - 2 : Is there a special Lazarus version for AMD64 ? Does it work on AMD64 ?

Please test! =) There is no pre-compiled binary for download, that´s for sure, but this may be because there is no mainteiner. I think it works. Well, it even works on win64!

If this does work, you could consider taking the Lazarus source RPM, compile it and produce a amd64 rpm package, and send it back to be included as a Lazarus download.

There are no x86_64 rpms, because at first we didn't have access to a x86_64 to build it. When I got (ssh-)access to one I started building snapshots using fpc 2.1.1, see
http://wiki.lazarus.freepascal.org/index.php/Lazarus_Snapshots_Downloads for downloads. (Don't forget to read the disclaimer.)

IMHO fpc 2.0.2 is not stable enough for lazarus on x86_64, so no releases are made yet. I hope the upcoming fpc 2.0.4 will be good enough.

Vincent.

Akain, Filipe, Vincent,
Thanks for your answers and advice.
At least it's reassuring that's not ignorance on my side that causes the problems. With the limited use of the examples ( I only tested a few) it seems that fpc 2.0.2-4.fc5 (is that a snapshot version? I can't find it on the site) is working "out-of-the-(rpm)box" but that the IDE fails. Of course you can write programs using some editor but from the earliest (Borland) pascal on, the IDE was an invaluable tool. I would like to know why it won't start in a 64-bit environment and if there is a source that can be compiled separately and is compatible with fpc 2.0.2-4.fc5. Filipe, I will try to compile a source but I assume I have to change the makefile rather heavily to account for the different environment and the different fpc version. Although being retired my time is limited (for various reasons) so it may take a while.
You'll here from me.

There are no 64 bits rpms for lazarus, except for snapshots.

So either use the snapshot rpms (http://www.hu.freepascal.org/lazarus/), release source rpms
(http://sourceforge.net/project/showfiles.php?group_id=89339&package_id=192183&release_id=420760) or follow the steps to compile from source:
http://wiki.lazarus.freepascal.org/index.php/Installing_Lazarus#Installing_from_source

Note, that you need three things: fpc, source code of fpc units (for code completion, e.g. fpc-src-2.0.2.xxx.rpm) and lazarus

Vincent

Thanks, Vincent,
Yes I had figured it out but fpc-2.0.20-4fc5 and fpc-src_.. (and fpc-doc...) are all in the FC5 package list.
Well, your mail gave me the link (http://www.hu.freepascal.org/lazarus/) that shows an fpc, fpc-src and lazarus rpm's for 64 bit! I hope later this day to give it a try (they are timestamped today) your working??)
If it functions as expected I'll report back and will inform the Fedora maintainers (probably via the forum).

No, you won´t. If you look into the Makefile you will notice it is already prepared for a huge number of architectures-operating system combinations. Also, the compiler version doesn´t change it´s executable name, so it has no effect on the Makefile. Only be careful to have the correct version on the compiler on the Path in case you have 2 different compilers installed.

Really, it´s just: make clean all =)

If it fails and the path is correct, then the compiler version is the problem.

thanks,

Isn´t is possible to run 32-bit software on your machine? I heard that some amd 64-bits machines can acctually run 32-bit software some how (has 2 processors, one 64 and one 32 or something like that). This way you could install the compiler and the IDE for 32-bits! It would also solve your question.

My questions: 1. Can programs compiled on a 64-bit system run on a 32-bit system (or is there a setting for it).

This will require a cross-built. The first thing to do is find cross-binutils suitable. I mean, as (the assembler), ld (the linker), strip and other binutils that run on a 64-bits environment but generate binaries for 32 bits.

Then you have to generate a cross-compiler (recompile the compiler to do that), and integrate everything.

Instead, this would be instantaneously solved if your machine can run 32-bit software.

Felipe,
Thanks. I will first try the current .rpm snapshot which is especially for 64-bit as well of fpc as for Lazarus.
I'll report back

Linux distributions support running 32-bit apps on an AMD64. This has little to do with the AMD64 processor itself.

I can perfectly run the 32-bit ppc386 on a 64-bit SuSE Linux.

Michael.

YEs, Michael, but my 64-bit FC5 can't run a 32-bit firefox, so I must use the 64-bit version.

That's probably because you don't have 32 bit versions installed of all the libraries it requires.

There is a post here about fpc with athlon 64:

http://community.freepascal.org:10000/bboards/message?message_id=155270&forum_id=24083#231973

It could be of use.

Felipe thanks, but that is not much relevant as it has to do with fpc running in 32-bit Linux on a AMD64 and that works( at least it did last year) but I want to run it in 64-bit Linux.
I have installed the overnight snapshot fpc-2.1.1-20060702.x86_64.rpm and it src companion without problems. However, fp is missing so I cannot start the ide (is it not in this package?). Then I installed lazarus-0.9.17-20060702.x86_64.rpm Also without a problem. when I started it the lazarus environment appeared. It gave a lot of warnings apparently due to the fact that the config-file was not quite correct but at least it started. However, I cannot do anything at all. When I try to drag e.g. a button to the form the buttonname is crossed and no button appears on the form. In the console it is complaining with all kind of messages (part is following): tmp]# lazarus &
[3] 22538
tmp]# TApplication.IconChanged - TODO: convert this message...no implementation in gtk or win32
NOTE: miscellaneous options file not found - using defaults NOTE: codetools config file not found - using defaults NOTE: help options config file not found - using defaults TMainIDE.DoNewProject A

[TCustomFormEditor.CreateComponent] Class='TForm'
TMainIDE.DoNewEditorFile end unit1.pas
TApplication.HandleException Access violation
Stack trace:
$0000003A16C3D242
and then a lot of lines like this, but it doesn't crash. I have not much experience with Lazarus so I have to dig into the manual(s) but at least it's a start. The same happens when I start as a normal user and not as "god".
Well a start is made. I first am going to find out where I can find the IDE, the lazarus problem will follow.
If somebody has suggestions pleas let me know.
