Hello,

I am back developing for Mac!

My compiled application with symbold is 93.5 MB in size and gdb cannot load it, so the debugger in Lazarus fails too.

This happens on both Leopard and Snow with FPC 2.2.x and 2.4.0 and Lazarus 0.9.28 and 0.9.29.

Only the 2 year old installation on Tiger still works.

Note that I have to use -Cg- to disable PIC due to some assembler code. Could this have an influence?

I tried to reduce the symbol size by compiling the LCL without symbols, but the option -g- did not do the trick - how could I try that?

Should I try installing FPC 2.5 from SVN?

Or install a newer gdb?

Any other ideas?

Thanks for any help!

Cheers,
Tobias

Stabs or DWARF (-g or -gw)? I've seen this in the past with DWARF and Lazarus-compiled applications, but never with Stabs.

No.

The option -g- does disable debug info generation. If it didn't work for you, that means that either the parameter was not actually used (I guess you did not specify it on the command line, but entered it in some dialog in Lazarus), or that after the -g- another -g parameter appears (which will reenabled debug information).

Should I try installing FPC 2.5 from SVN?

That could help if you are using DWARF. Almost nothing has been changed to Stabs.

Or install a newer gdb?

Unlikely (and that's not very easy).

I think Stabs, but apparently it worked with Dwarf in one particular installation. I will need to look into it more. Lazarus still says "Oops, debugger error" so I need to find out how to look at the communication between Lazarus and gbd to see the actual error.

With FPC 2.4.0 I get Fatal: Compilation aborted: Unhandled exception at ... on line 1 of some units. So I will try to install 2.5.1 from SVN ...

Does it still happen after cleaning the project and then rebuilding it?

I manually deleted all .ppu, .o, and .rst files and it happens on a fresh build.

By the way could -Cs20000000 do any harm? Maybe one 0 too many?

I saw 2.4.3 for Windows on the snapshots page, is there any such update for Mac?

Kind Regards,
Tobias Giesen

Then please file a bug report with source code to reproduce the crash.

The stack size only affects stack checking on Unix platforms. It has no influence on the program in any other way.

I don't think anyone builds FPC snapshots for Mac OS X.

I'd love to but probably it only happens in my project with close to 500 units, it can be really hard to strip such things down. There is unfortunately a lot of closed source code in it.

I will try installing FPC 2.5. Probably going to take a while to figure that out from SVN.

Hi,

I have the sources from SVN now, do I just cd into the folder and type make?

I couldn't find any documentation on making FPC anywhere on freepascal.org. Maybe I missed something?

On the website on the right is a link "Documentation".

OK after some more searching I found the Building faq (PDF) on http://freepascal.org/moreinfo.var
