Hello,
I downloaded and installed the latest Lazarus binary from source forge:
Lazarus-0.9.22-fpc-2.0.4-20070326-win32.exe
Apperently everything that is needed is inside this installer (?) which
is real nice.
I give it test by writing a little HelloWorld program and then during
debugging/running gdb.exe crashes, here is the program:
[snip]
My operating system is:
Windows XP Pro x64 Editition.
A debugger crashing doesn't seem normal to me... ?
I see you're running XP64... me too
Did you try gdb standalone running your app ? And dit it crash while
starting the app ?
I just tried it:
C:\Tools\Lazarus\mingw\bin>gdb.exe HelloWorld.exe
GNU gdb 6.0

This GDB was configured as
"i686-pc-mingw32"..."C:\Tools\Lazarus\mingw\bin/Hello
World.exe": not in executable format: File format not recognized
When I try:
j:\junk\gdb
gdb is started.
Apperently the gdb folder/path is added to the operating system environment
variables.
I have also installed a free pascal cross compiler which compiles to X64.
Maybe that's causing problems ?
Maybe Lazarus is using the wrong gdb.exe ?
However I explicity set the search path to gdb.exe in Lazarus options...
But maybe that not helping who knows.
However this theory can go into the waste basket since the cross compiler
only has one executable.
Strange.
Apperently gdb can't read the file format ?
I'll try free pascal's gdb as well:
C:\Tools\Compilers\Free Pascal\2.0.4 Stable for Win32\bin\i386-win32>gdb
j:\junk
\HelloWorld.exe
GNU gdb 6.2.1

Same problem, file format not recgonized.
Maybe I am not using the proper command line options ?
Surely Lazarus would use the proper command line options ?!?
I also tried downloading gnu debugger from it's website.
The wacky zip only contains sources codes which is a real bummer.
No binaries.
I shall download your patched binaries and see if they work with lazarus,
etc:
C:\Tools\GNU Debugger\gdb.6.6.patched>gdb.6.6.patched.exe
j:\junk\HelloWorld.exe
GNU gdb 6.6

recognized
(gdb)
Same problem, I'm probably not using the correct command line options.
Well one last final try with Lazarus ;):
MANY THANKS !
The Patched 6.6 GNU Debugger works with Lazarus, which puts a BIG SMILE ON
MY FACE =D
I must admit I am also running Delphi 2007 next to Lazarus... who knows..
maybe that could create debugger conflicts.
However the first time I tried the GNU Debugger it did execute but after
execution it still kinda crashed...
But maybe this was because other flawed (?) gnu debuggers were still running
in memory.. or maybe it still has a problem... I don't know..
I termined all gnu debuggers in memory and test the patched 6.6 a couple of
times... and now each time it works ok.
I shall use it in the coming days to test Lazarus and Free Pascal some more
and if I ran into problems I'll let you guys know.
Bye,
Skybuck.
