Re: [fpc-pascal] Linux Linking Error]

[Rick Seiden]

(I sent this earlier today, but haven't seen it on the list.  It's been 
over 5 hours, so I'm resending.  I'm sorry if you end up getting both!)


From the FPC IDE.  I have not installed Lazarus at this point.

I'm not sure how to compile from the command line.  I'm sorry, I'm a 
lame Windows person trying to make it in the Linux world, so command 
line calls aren't second nature to me.  I can't even get the mouse to 
work in the FPC IDE!


So, if you could give me the command I should use to compile, I'd be 
happy to post the full error message.


Thanks again
Rick

I assume you are running this from some IDE ? The text mode IDE or the Lazarus 
IDE.
It would be instructive to try and compile from the command-line, this way
you'll get the complete error message.

In the case of Lazarus, start lazarus from within a console window. The
error messages of the compiler and linker will then also be displayed on
the console window.

The reason is that the mail also contained an html version. All such  
mails are held for moderator approval because it stops most spam and  
viruses (just filtering on list member addresses is not enough,  
because there have been cases in the past where viruses were sent  
with the address of a subscriber forged in the from-field).


I don't mind letting such mails through every morning, but when you  
send such mails there will indeed be a delay before they appear on  
the list. If you want to turn off html mail, see the following url

You can't compile on amd64, since you still have to create the compiler (and
debug the actual problem).

So you need:

- a starting compiler (2.0.4 or 2.1.4)
- a 2.3.x (development) snapshot or svn checkout, which are afaik on FTP's
  server. Note that sourceforge only contains releases, not snapshots

Then you need to crosscompile (see http://www.stack.nl/~marcov/buildfaq.pdf
) to AMD64, and fix the problems in the end.

It is possible to create a binary for amd64, but that binary doesn't work,
and I don't know why. FreeBSD keeps complaining it can't execute it.

[fpc-pascal] Using AnsiString/WideString with C Library

[gmjimen]

Hello.

I'm writing a wrapper for a C library that allows the use of UNICODE. I did
wrappers for C libraries but using only ASCII strings. I did:

UNIT example;

INTERFACE

PROCEDURE Proc (Text: ANSISTRING);

IMPLEMENTATION

  { Wrapper for the C function. }
  PROCEDURE _C_Proc_ (Text: PCHAR); CDECL; EXTERNAL 'lib.dll' NAME 'proc';

PROCEDURE Proc (Text: ANSISTRING);
BEGIN
  _C_Proc (PCHAR (Text));
END;

END.

This way I can use Pascal strings with C functions.

I've read the documentation and I find that I can use WIDESTRING in a similar
way, but I'm not sure which character codification WIDESTRING uses. The C
library uses 'standard C strings' (that is 'char *string;') an there's a
function to define the character codification to be used by the library. It's
possible to use ASCII, UTF-8, UTF-16 and UTF-32.

Can WIDESTRING use all UNICODE codifications and ASCII strings?

If it can't, is there a way to use UNICODE strings?

Thanks in advance.

UCS2 which is a subset (more like a draft for) of UTF16.  Maybe Microsoft
has fixed this to be fully UTF16 compliant in XP+ though.

If there are differences, they revolve around the differences between UCS2
and UTF16. (surrogate pairs mostly, maybe endianess support)

There is no such thing. There are multiple unicode encodings (UTF-*, UCS-*
etc)

An ansistring uses 8 bit characters, while a widestring uses 
16-bit characters. A widestring is normally UCS-2 or UTF-16 encoded.

Assignments to and from ansistrings convert to and from the system code 
page, i.e. if the system uses an ISO-8859-1 encoding, converting 
ansistrings from/to widestring converts to/from ISO-8859-1.
Further, there is utfencode and utf8decode, which convert an utf-8 
encoded ansistring to/from a widestring.

gdk_window_get_frame_extents(GDK_WINDOW(widget^.window),@grect);

Thanks for the answers.

I think I'll duplicate the functions, one for ASCII (ANSISTRING) coding and
the other for UTF-8 (WIDESTRING). I think this is the best way.

But I've look for the description for UTF8Encode, UTF8Decode, UTF8ToAnsi and
UTF8ToUnicode in the documentation and I can't find it. What does they do?

A widestring is not suitable to hold a utf-8 string. A ansistring on
the other hand is. (ansi is just a name .. it can hold iso or utf-8
strings)

A widestring is suitable to hold ucs-2 or utf-16 strings.

What are the permissions exactly ? You should be able to execute ld as

You would think that would allow me to execute it as a normal user.  The

is write it, but...


I was going to copy and paste the output to prove that it didn't  do it,

said it couldn't find /usr/bin/ld.  I just did ls, saw it there, with

[fpc-pascal] No Browser Info Available

[Rick Seiden]

I'm having problems running fp ide under Ubuntu 6.x under VMWare 
Workstation 5.5.


I go to an xterm session, and then run fp.  The first mouse click 
generates an error that is obviously from FP.  It says


No Browser info available

with an OK "button".

After that the mouse won't work in the terminal window at all.  I've 
searched and can't find anything on this.  Anyone have any ideas?


Thanks in advance.

Got 2.0.4

Got from ftp.


Then you need to crosscompile (see http://www.stack.nl/~marcov/buildfaq.pdf
) to AMD64, and fix the problems in the end.


Got it.
Trying to figure out the right parameters.

cd ~/fpc
gmake distclean
# next all on one line
gmake all install CPU_TARGET=x86_64 OS_TARGET=freebsd CROSSBINDIR=~/cross/bin 
BINUTILSPREFIX=x86_64-freebsd-INSTALL_PREFIX=/usr/local

Does the install_prefix at the end installs anything on /usr/local?
or is everything installed on ~/cross/bin
Don't want to install a chunk of am64 code on an i386 machine. :-)

[fpc-pascal] building snapshot

[Francisco Reyes]

Although ultimately my goal is to try to cross compile to amd64 from i386 
(FreeBSD) I figure I would start easy with a "standard compile".


The process completed.
When I run compiler/utils/fpc
It reads:

Free Pascal Compiler version 2.0.4 [2007/05/25] for i386

I downloaded the 2.3 snapshot (ot at least that is what I thought).

[fpc-pascal] Optimization levels

[Francisco Reyes]

Looking at the compiler parameters I see:

-Oggenerate smaller code
-OGgenerate faster code (default)

Is the difference in speed/size significant?

-O1level 1 optimizations (quick optimizations)
-O2level 2 optimizations (-O1 + slower optimizations)
-O3level 3 optimizations (-O2 repeatedly, max 5 times)

Is it safe to use any of those?
When, if at all, it could be a bad idea to use them? 


-Op target processor:
-Op1   set target processor to 386/486
-Op2   set target processor to Pentium/PentiumMMX (tm)
-Op3   set target processor to PPro/PII/c6x86/K6 (tm)
-Op4   set target processor to Pentium 4 (tm)
-Op5   set target processor to Pentium M (tm)

Which of those would be 586 and 686 type CPUs?
Specially AMD cpus.

Like.

[fpc-pascal] When is make cycle needed?

[Francisco Reyes]

Reading the docs I see there is a "make cycle" target, but I am not sure 
when it is necessary.


For the snapshot build seems that only "make all".
So when is make cycle needed?

Perhaps it is my newbiness, but the explanation in the manual doesn't mean 
much to me.


"make cycle" is a bootstrap of the compiler, and builds the rtl and compiler 
at least three times. The only starting point prerequisites are installed 
binutils and a starting compiler.

Whenever the compiler changes.

It's to make sure that a compiler change does not cause any errors:
the changed compiler (ppc1) must generate a compiler binary (ppc2)
which is then used to create another compiler binary (ppc3) - the 
last 2 binaries must be exactly equal.

Try running compiler/ppc386. fpc simply executes the first  
ppc it finds in the path afaik.

Usually not.

Yes.

When you want to debug the result, or when you want a quick compile  
(higher optimization levels take more time).

-Op3. It will make very little difference though.
