There was a recent announcement on the free pascal mailing list that a new 3.0 branch of the FPC was committed to svn.

I decided to checkout a copy of the branch and using it with the latest official release of Lazarus, which I believe is 1.2.

The problem is I get errors when I "make all" on Lazarus 1.2.

Here are the svn repositories I checked out:

http://svn.freepascal.org/svn/fpc/branches/fixes_3_0 http://svn.freepascal.org/svn/lazarus/branches/fixes_1_2

Here is a listing of the "make all" output:

Oh, and here is an extra bit of information I neglected to mention. When I use FPC 3.0.1 to compile against the trunk version of Lazarus, there are no errors.

The point is, I think we should have a fixes version of Lazarus which can build with the new fixes 3.0 version of FPC.

Don't expect that lazarus 1.2 will be changed to be compileable with fpc 3.0 (in that case someone may ask same thing for lazarus 1.0). Trunk compiles with 3.0, so lazarus 1.4 will be able to compile with fpc-3.0.

I'm currently trying to test some of the less-common architectures with the end-of-era 2.7.1 and Lazarus trunk. Obviously this is a personal effort, but on occasion some sort of marker indicating which version/revisions on the FPC and Lazarus svn systems /should/ work together would be useful.

I've had a lot of hardware problems over the last year, and in several cases finding the correct combination of compiler and LCL that would allow me to reconstruct a particular binary was tricky. I've spent a bit of time over the weekend working out ways that I can insert the svn revision numbers of all relevant parts (i.e. a project itself, FPC and Lazarus) into a binary when it's built, but that's not much help for some of the older binaries particularly those which had to be built with FPC 2.7.1 due to code generation issues.

Lazarus 1.2 is soon history. Use the new branch for 1.4 instead : svn.freepascal.org/svn/lazarus/branches/fixes_1_4/ Bug reports for it are welcome.

Juha,

Okay great. It looks like the 1.4 branch you mentioned was created by mattias a few hours ago in revision 47333.

I'll be building installers to test Lazarus 1.4 and FPC 3.0 momentarily. Installers will be for OSX, Linux, and Windows.

PLEASE !!!
who write installers, share uninstall script as well, no any info about where to file copied. why hide like a fusion formule ? for fpc , copied same files to /bin, usr/ xxx bla bla... my idea is, add in installed folder in fpc.cfg so no need to copy files. for permission, define new group and installer folder owner set this group name (group name can fpc or/and lazarus [like a firebird]) who wantto use fpc or lazarus, user add to this created to groups.

I've been building FPC 3.0 and Lazarus 1.4 from svn sources. Here are some problems.

First, all Linux builds seem to be working correctly.

On Windows though I encountered a few problems.

1) In lcl\interfaces\win32\win32callbacks.inc lines 1547 and 1571, the following cannot compile:

  ItemState := TOwnerDrawState(PDrawItemStruct(LParam)^.itemState);

2) There is a similar problem in lcl/grids.pas:

  cfg.SetValue(AKey + '/style/value', Integer(AFont.Style)); // around

line 1905

  AFont.Style:= TFontStyles(cfg.GetValue(AKey + '/style/value', 0)); //

around line 1913

Hi,

Crosscompile working for me from Linux x86_64 to Windows i386-Win32 with FPC fixes_3_0 29421 and Lazarus fixes_1_4 47347.
