[fpc-pascal] Help with understanding HeapTrc output
Sorry, but I know the output below is going to wrap horribly. I'm self-taught when it comes to understanding the heaptrc output. I also couldn't find clear documentation explaining the output. From the information below, I gathered the following information. But a few points I'm not sure about... 1) Every Call trace for block is a memory leak, correct? 2) Each Call trace for block is where the memory was allocated (start being used)? 3) I should trace the information from the bottom line to the top line... 4) Why does it quote more than one line?

[fpc-pascal] PowerPC: zipper streaming error
Hi all, Is anyone working on the unit zipper? I came across a problem when using the zip objects on PowerPC - they don't like files zipped on i386, and i386 don't like files zipped with PowerPC, but the PowerPC can zip its own files and read those again. I guess the zipper unit is lacking a check for big endian processor. Where can I report a bug for FPC? Btw, I'm using FPC 2.2.2. Thanks, and best regards Normann ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
[fpc-pascal] a few installation issues (trunc on freebsd)
I have a few question, regarding my attempts to install fpc from trunc (I read the build faq, yet I have not succeeded...) On a freebsd (7.0) box, I have downloaded and installed the pre-compiled fpc 2.2.2 ( to use as my initial compiler.) I have created my workind dir /data/fpc_trunc/svn and done my checkout (Revision: 12021) cd /data/fpc_trunc/snv svn co http://svn.freepascal.org/svn/fpc/trunk . then according to the build-faq, I have done cd compiler gmake cycle * First problem: I found if I simply go to the parent (svn) directory, and do a gmake all PP=/data/fpc_trunc/svn/compiler/ppc386 there, it will do some clean out, and stop because halfway through it will have deleted this compiler. So instead (which is not mentioned in the buildfaq?), I have installed the compiler and rtl at this stage: gmake install INSTALL_PREFIX=/data/fpc_trunc/inst/ cd ../rtl gmake install INSTALL_PREFIX=/data/fpc_trunc/inst/ Note: I am installing to a separate dir, as I want to use this installation in parallel to other installations. * Second Problem: when using fpc (instead of ppc), it will always find the ppc386 in the default installation. The only way I can change this is fpc -Xp/path/to/my/ppc386. (Which I found no documentation for. I got that from looking through the source) However, if I want to use fpc from lazarus, I may not be able to pass that (convenient) on the command line. Is there any INI file? (fpc.cfg did not help here, at least not the fpc.cfg in the same path as fpc exe). Or is it save to substitute fpc, with ppc386 everywhere it is called? any way I then go and create my fpc.cfg: cd ../../inst ./bin/fpcmkcfg -d basepath=/data/fpc_trunc/inst/lib/fpc/2.2.2 bin/fpc.cfg * 3rd problem, it uses the same prefix for the units (-Fu) and the bin (-FD), so the above creates correct -Fu config, but I must change the -FD conf. Any solution to this ? -Fu will be correct: -Fu/data/fpc_trunc/inst/lib/fpc/2.2.2/units/$FPCTARGET/rtl but -FD will *NOT* be (which I think it should?, or am I wrong?) -FD/data/fpc_trunc/inst/bin now I go back to the top svn checkout and to gmake all PP=/data/fpc_trunc/inst/lib/fpc/2.2.2/ppc386 * 4th Problem the compilation aborted (Sorry I don't remember where) because it tried to access the x11 package = I did solve that by going int packages/x11, did the make there, and did install it (with the install prefix) * 5th problem packages/graph stops, because it tries to use x86. (This exists in the sources rtl/unix/x86.pp) Somehow all the above has not installed this (not on my FreeBSD), the package is missing int he inst/lib directory And last not least, having checked out trunc (or being under the impression to have done so), why has the make install in the rtl installed something with 2.2.2 in the path? (If I run the ppc386 that was installed it will say 2.3.1. Maybe this last bit will solve some of the other questions... Any help is greatly appreciated. Many thanks.

I got that from looking through the source) However, if I want to use fpc from lazarus, I may not be able to pass that (convenient) on the command line. Does lazarus call fpc or ppcXXX? Is there any INI file? No. (fpc.cfg did not help here, at least not the fpc.cfg in the same path as fpc exe). Or is it save to substitute fpc, with ppc386 everywhere it is called? Yes, that's safe. any way I then go and create my fpc.cfg: cd ../../inst ./bin/fpcmkcfg -d basepath=/data/fpc_trunc/inst/lib/fpc/2.2.2 bin/fpc.cfg I'm not sure how well maintained fpcmkcfg is. For the (*nix) releases we use the samplecfg script (from compiler/utils) to generate configurations. But you shouldn't need a new configuration file, afaik samplecfg is identical in fixes and trunk (and in 2.2.2). * 3rd problem, it uses the same prefix for the units (-Fu) and the bin (-FD), so the above creates correct -Fu config, but I must change the -FD conf. Any solution to this ? -Fu will be correct: -Fu/data/fpc_trunc/inst/lib/fpc/2.2.2/units/$FPCTARGET/rtl but -FD will *NOT* be (which I think it should?, or am I wrong?)
Re: [fpc-pascal] widestring related? problem on arm (2.3.1)

Stems from ANSI2WIDEMOVE in cwstring.pp returning ESysEBADF (9). Do I need to define something on arm for widestrings? Run time error 231 in the unix wide string manager means that iconv returned an unexpected error code (in the sens that it's not supported by the code in the cwstring unit). Since you already compiled the cwstring unit with debug information, you can step into it (or set a breakpoint) and see what the error code is (or just add a writeln). Once you find out, it'll probably be easier to figure out what the problem is. Thanks Jonas - the error no is 9 - ESysEBADF - System error: Bad file number. The same code runs on x86_64 no probs and has been working on arm, but its been a month or so since I tried it on the arm hardware. I will install gdb on arm and see whats up.
