Build lazarus os OSX PPC, some problems.
« on: March 11, 2017, 06:26:43 pm »
Hello
  {first post here, hello to all lazarus-user|dev}

On a PowerMac G5, osx 10.5.8 i build some version of Lazarus:

Lazarus-1.6.2 + fpc 3.0.2 : build ok out of the box, ad seems funcional, compile ad run fine.

Lazarus-1.4.2 and 1.4.4 + fpc-2.6.4 builds ok, and compile a simple test program, but show both a similar problem: selecting Tool->Option both gave error:

lazarus-1.4.2:

TApplication.HandleException Error reading ComponentsListView.Items.LazData: Stream read error

That suggests that there was an error regarding handling big endian systems in the LCL of Lazarus 1.4.x, or in FPC's component streaming.

Interestingly, this old issue related to endianness seems to have been resolved in Lazarus 1.6.
function GetRandomNumber: integer; // xkcd.com
begin
  GetRandomNumber := 4; // chosen by fair dice roll. Guaranteed to be random.
end;
