Thread: Class operators in Freepascal records like in Delphi 2010?

It does full clean-make-install cycle.

    set FPCMAKEPATH=C:/dev/fpc/2.4.2

    set OUTPATH=C:/dev/fpc/2.5.1

    %FPCMAKEPATH%/bin/i386-win32/make all FPC=%FPCPATH%/bin/i386-win32/ppc386.exe

    for /r %OUTPATH%\examples %%d in (.svn) do @rmdir /s /q %%d
    :quit

    As of Lazarus, just point FPC directory to C:/dev/fpc/2.5.1 (or wherever you set OUTPATH in the above .bat file), and use built-in feature to recompile it.
    Wow! thanks alexione! I will download the new fpc and try this out

    cheers,

    @alexione: hmm...I have downloaded the trunk fpc, but I have some questions.

    1. Do I set the %OUTPATH% string to the fpc folder that I just downloaded from SVN?
    2. Where do I put the batch file to do the compiling that you gave me? In the root fpc folder in 1 ?

    cheers,
    Paul

    Press any key to continue . . .
    I don't know what happened...do you think this means I need something path in my path environmental variable or similar?

    This is my compile script batch file that I placed in the g:\fpc\2.5.1 folder contain the SVN source and make file, etc.:

    Code:
    set FPCMAKEPATH=C:/lazarus/fpc/2.4.2
    set FPCPATH=C:/lazarus/fpc/2.4.2
    set OUTPATH=G:/dev/fpc/2.5.1
    for /r %OUTPATH%\examples %%d in (.svn) do @rmdir /s /q %%d
    %FPCMAKEPATH%/bin/i386-win32/make clean FPC=%FPCPATH%/bin/i386-win32/ppc386.exe

    for /r %OUTPATH%\examples %%d in (.svn) do @rmdir /s /q %%d
    :quit
    pause
    G:/dev/fpc/2.5.1 is where I want to install? freepascal 2.5.1, and C:/lazarus/fpc/2.4.2 is where (obviously, DUH!) where I have the existing freepascal comiler...

    It has nothing to do with directories. The problem is that you don't have binutils's gas assembler(as.exe) in your path. This is for some reason required when building the textmode IDE

    Ok, I have now added C:\lazarus\fpc\2.4.2\bin\i386-win32 to my path in the batch file (has as.exe there), so I will see if this helps

    Sweet! I think it worked...no errors now

    Here is the updated batch file:
    Code:
    set PATH=%PATH%;C:\lazarus\fpc\2.4.2\bin\i386-win32
    set FPCMAKEPATH=C:/lazarus/fpc/2.4.2
    set FPCPATH=C:/lazarus/fpc/2.4.2
    set OUTPATH=G:/dev/fpc/2.5.1
    for /r %OUTPATH%\examples %%d in (.svn) do @rmdir /s /q %%d
    %FPCMAKEPATH%/bin/i386-win32/make clean FPC=%FPCPATH%/bin/i386-win32/ppc386.exe
    if errorlevel 1 goto quit
    %FPCMAKEPATH%/bin/i386-win32/make all FPC=%FPCPATH%/bin/i386-win32/ppc386.exe
    if errorlevel 1 goto quit
    %FPCMAKEPATH%/bin/i386-win32/make install FPC=%FPCPATH%/bin/i386-win32/ppc386.exe INSTALL_BASEDIR=%OUTPATH%
    for /r %OUTPATH%\examples %%d in (.svn) do @rmdir /s /q %%d
    :quit
    pause
    All I have to do is try it out now with Lazarus

    Ok, now I'm having another issue...it is obviously because I am using a different version of FPC to compile my Lazarus projects now, but I am not sure what to do about it

    My Lazarus projects can't find standard units like IniFiles, Contnrs, etc. and I am unsure how to proceed.

    Here is a screenshot of my Lazarus Environmental (Files) options:



    And here is my fpc.cfg file (version 2.4.2, the 2.5.1 doesn't have one):

    Replace all mentions you can find of 2.4.2 with 2.5.1, and you should be good again

    Units compiled with a different version of the compiler cannot be used by the same compiler. It might be a very different PPU structure. Hence, you will also have to recompile lazarus when you've inserted the new FPC version info
