Lazarus and Windows XP:

for some days now i get this error message

C:\lazarus\lcl\intfgraphics.pas(641,49) Error: Identifier not found
"TTiffIFD"

while trying to compile svn lazarus after svn update

I tried svn cleanup and deleted the whole /lazarus directory tree without success

Perhaps that happens due to an old svn vesrion? -> Subversion 1.6.3

No probs with Debian Linux!

To compile Lazarus svn you need fpc 2.6.0 or a recent fpc 2.6.1 or a recent fpc 2.7.1.

we need a STLA (Search the List Archives) button :LOL:

what version of FPC are you compiling with? IIRC, that's the problem...

counting your message, there are 6 messages with TTiffIFD in them... make that 7 with mine... i've not seen other responses to your message yet...

the others are as follows...

HTH

Plus others in fpc-devel. What we need is a "I've just committed something to svn trunk which breaks it for 2.6.x, normal service will be resumed shortly" button.

hahaha... i *knew* that i had seen other posts about that problem but i got sidetracked and my message was waiting to be sent for over an hour... i should have searched those other lists in my thunderbird before sending it :?

hehehe... that, too!! :LOL:

Feeding that error message to Google results in one hit- a months-old bug report in Mantis that's now closed.

Now granted that this issue has arisen when somebody's trying to recompile Lazarus from the command line rather than from inside the IDE, but I wonder if there would be some way to extract error messages from reported bugs and have an "is this a known problem?" button?

In any event, having to know exactly what revision of FPC to use for/with Lazarus is a problem, and the potential of having (temporarily) broken Lazarus revisions is a bigger one.

That would be wrong.
fpc 2.6.1 was changed, which broke Lazarus. Lazarus was adapted, so it can not compile with older fpc 2.6.1.
Compilation with fpc 2.6.0 was not affected.

With emphasis please on my "normal service will be resumed shortly", I'm not suggesting that the core developers gratuitously break things. I was thinking of cases where something is changed in one or other of the projects, and where somebody knows that this will cause problems for minutes or hours (or, in very rare cases, days). Some sort of "health warning" would be useful, so that people (or scripts working on their behalf) know that it's best to hold off any updates to their local copy until the situation is resolved.

To compile Lazarus svn you need fpc 2.6.0 or a recent fpc 2.6.1 or a recent fpc 2.7.1.

Not too recent a 2.7.1. Anything newer than rev 22340 makes lazarus crash on some systems (it'll compile though).

Yes. It seems to be a compiler bug that somewhere causes memory corruption. It runs on my Linux 64bit without problems even with heaptrc and many checks on, so I have no idea how to help here.

Or use gitk ever now and again, to see a nice visual history of Lazarus development. Complements of git of course. ;-)

I wonder if there is any way of maintaining an "islands of stability" graph, tracking e.g. which revisions of Lazarus trunk are known to compile and work with which revisions of FPC 2.x.1?

Good news. It seems to be fixed:
