You may also have a problem with swap space. Have you increased swap?
A figure of 1000 or even 1200 MB is needed in my experience.

[Lazarus] Syntax error compiling fpc 3.0.0 3.0.0rc1 3.0.0rc2

[Donald Ziesig]

Hi All,

I ran out of room on the raspberry pi's 8GB NOOBS SD card so I just 
created a new SD 16GB card with the latest version of Raspbian.  I got 
all of the usual tools working in short order (VNC, SSH, FTP,...).


Then I decided to build a completely new version of FreePascal and 
Lazarus from source (just to prove that I can ;-) ), but I can't compile 
any style of fpc 3.0.0 from:


svn co http://svn.freepascal.org/svn/fpc/tags/release_3_0_0_rc2 fpc2
svn co http://svn.freepascal.org/svn/fpc/tags/release_3_0_0_rc1 fpc1
svn co http://svn.freepascal.org/svn/fpc/branches/fixes_3_0 fpc

I am using fpc 2.6.4 as the bootstrap compiler.

The error is consistent at flt_pack.inc, line 119.  The message is 
"Syntax error while parsing a conditional compiling expression".


I looked at the code and although it is not a trivial expression, I 
can't see anything wrong with it (unless one of the conditional define 
values is erroneous):


{$if defined(fpc_softfpu_implementation)
   or ( defined(FPC_SYSTEM_HAS_extractFloat64Frac)
 and defined(FPC_SYSTEM_HAS_extractFloat64Exp)
 and defined(FPC_SYSTEM_HAS_extractFloat64Sign)
)}

I am using the command:

make clean all OPT="dFPC_ARMHF -CX -CfVFPV2 -CaEABIHF -OpARMV6 -O2 
-XX -Xs"


from mitchelcomputing.co.uk (slightly modified).

==

I tried commenting out the entire conditional statement and replacing it 
with a failing conditional:


{$ifdef DRZ} // DRZ is not defined.

The compilation then ran to completion but the build failed because 
"Binary files ppp3 and ppcarm differ".  (Why there are two executables 
and what it means that they are different is beyond me :-[ ).


That error message is followed by many "recipe failed" messages.

Both ppp3 and ppcarm (which were left in the compiler directory) execute 
successfully in that they report version 3.0.1 for arm with detailed 
usage information.  I haven't tried compilation with them (yet).  I will 
try "hello world" a little later today (have to run an errand for my 
wife) and report the results.


I don't want to spend the time compiling Lazarus till I get a clean 
build and install of fpc.


Any help will be appreciated.

Thanks,

Don Ziesig

make sure you start off with a binary tailored for the Rpi. I think that 
the last time I started from scratch I got it from


http://sourceforge.net/projects/mseide-msegui/files/fpcarm/

Current Raspbian provides the necessary prerequisites, but you might 
need to tweak fpc.cfg or provide an explicit -Fl.


The compilation then ran to completion but the build failed because 
"Binary files ppp3 and ppcarm differ".  (Why there are two executables 
and what it means that they are different is beyond me :-[ ).


Because the standard build checks that repeated recompilations are 
substantially the same.

Donald, if all you want is a minimal FPC 3.0.0 for the Pi, I suggest you
use my minimal installers from http://www.getlazarus.org

The minimal version weights in at 40MB and includes the compiler, a few
tools like the console "fp" ide, and the rtl (no fcl, no lcl). I also
includes a fpc terminal shortcut which opens you default terminal with fpc
envirnonemt variables and configuration setup. It will not interfere any
other existing FPC or Lazarus setup. It also makes for a good starting
point to make the FPC compiler from sources:

Minimal Pi PFC 3.0.0:

http://cache.getlazarus.org/archives/fpc-3.0.0.raspberry-min.tar.gz

If on the other hand you want to run a newer version of Lazarus with FPC
3.0.0 on the Pi, I also have a bundle for that. It's also quite small (I
know SD card space on the Pi is a concern) at under 200MB for FPC 3.0.0
plus Lazarus. The FPC in this bundle comes with rtl, fcl, and a few other
packages (again some have been removed), and the Lazarus version has had
the graphic image sources, and tool sources removed (though tool binaries
are included).

This reduced in size and Pi specific FPC 3.0.0 with Lazarus can be
installed from here:

http://www.getlazarus.org/setup/?download#raspberry_pi

Final note:

I know many Pi users are concerned about the SD storage space required by
FPC and Lazarus and I've taken some care to reduce their sizes on Pi, but
please be aware more SD space will be used and is required when compiling
with Lazarus. The first time you build with Lazarus it will require space
to store the lcl compiled units (two hundred plus megabytes more), and any
lcl programs you write and compile can take upwards of 20-30MB each. If you
want to keep some of your compiled programs around, consider using the
"strip -s yourprogram" utility to reduce their size after you're done
developing a program. The storage saving will be significant.

Hi again Anthony,

I used your tiny version on my original SD card and it works fine, but I 
need the full-up debugging version on the big SD card.  With the 
additional 8 GB I don't think I'll have space problems.  If I do, I'll 
remove Python and Mathematica like I did on the original SD card.  That 
freed up a lot of space.


Thanks,

Don
