Hi all,

I have installed and applied succesfull all patches from the dbgrid_dist.tar.gz.

all access to dbase and interbase(firebird) produce a access violation. (mysql not tested). Passwords, username, path - all ok. and set to my environment.

The next step was to run the ibtest from the fpc1.1 source tree and the same access violation occurs:

testib

An unhandled exception occurred at 0x080824E3 :
EAccessViolation : Access violation
0x080824E3

Then I tested the ibase60 unit, the following error occurs:

./testib60

Connecting to testdb.gdb: OK.
Starting Transaction : Runtime error 216 at 0x08055623 0x08055623
0xBFFFED64
0x4007FDD7
0x08059DAD
0x080486A7(gdb) run

the next step was to compile with debug option and this is the output:

[New Thread 1024 (LWP 3241)]
Connecting to testdb.gdb: OK.
Starting Transaction :
Program received signal SIGSEGV, Segmentation fault. [Switching to Thread 1024 (LWP 3241)]
0x4007fa25 in isc_start_multiple () from /usr/lib/libgds.so

Can anybody help me?

p.s.
hi jesus, I send this also to the fpc-devel list
thx

Is this 1.1 or 1.0 ?

Did you try this in version 1.0 ? It works with that version for me. If it does not work in version 1.1, one of the compiler guys will have to look at it...

It seems that TIBQuery.IsCursorOpen its not implemented, it simply returns false, this prevents buffer allocation.

I set

function TIBQuery.IsCursorOpen: Boolean;
begin
  Result := (FDatabasenil);
end;

but I'm not sure if that is enought, at least the test proyect in dbgrid_dist runs ok. still there are problems on closing the program, I'm investigating...

if somebody wants to try here is the link to the lazarus proyect and fcl/db patches (without this report):

Sorry, I should say that I was using 1.0.8-pre1. With 1.1 I get Access Violation too, but I can debug!. here is what gdb shows:

This looks like a Lazarus problem and not a DB problem

This is in version 1.1, in version 1.0.7 it works.

Am Mittwoch, 23. April 2003 20:21 schrieb Jesus Reyes I think this is fixed with the actual cvs version from fpc and lazarus
