Recomplile the RTL for 2.5.1 - How to do this ?

[delphian]

Guys i need to make a small change to the rtl in 2.5.1 . i understand i need to rebuild the FPC to do this , i'm using win64 as the OS and x86_64 aswell , how do it do this ? am right in saying i need to recompile the exe for FPC ( fpc.exe ) from the 2.5.1 source complier directory ?

Depends: if your change affects the compiler, yes, you need to rebuild fpc.exe.
If the change affects how your own app runs => you only need to rebuild the RTL (and packages).

In practise there is little difference, you run make all, and it does both.

I have my fpc as a checkout from SVN, but it should be the same anyway.

To compile the RTL (and/or fpc itself) you need a working compiler. fpc 2.4.0 prefered, but 2.5.1 may work (but does not always).

change into the fpc directory (where the sources  are)

path_to_make\make.exe clean distclean

path_to_make\make.exe all   FPC=c:\path_to_fpc_orPPC386\fpc.exe
  or put in whatever option you want it compiled with
  path_to_make\make.exe all  -OPT="xxx"

path_to_make\make.exe  install  INSTALL_PREFIX=c:\path_to_your_installation  COPYTREE=echo

You may have to delete the example directory of your previous installation, before you an install.

Thanks Martin

I've got FPC recompliled , i think i've done the bits to get lazarus done but when i got complile my app it complains as if the RTL hasnt been changed. ( i copied the new fpc into my lazarus dir where it belongs , checked the date to made sure i grabbed the correct one and also checked activeX.pp which i have changed in both packages\winunits-base\src in the source dir from the compliler for 2.5.1 & where it is in lazarus..)

any clues ?

activeX.pp doesn't matter. you need activeX.ppu

When you made the compiler, it should have recompiled the RTL too, and created all ppu files.

When you compile a project (or even Lazarus itself), it compiles using the ppu files.
