Hi Philip,
I'm still having this framework issue.
When I run the otool -L <myapp> command I get
/System/Library/Carbon.framework/Versions/A/Carbon ( Compatibility
version 2.0.0, current version 128.0.0)
/usr/lib/libz.1.dylib ( compatibility version 1.0.0, current version
1.2.3)
/usr/lib/libSystem.B.dylib ( compatibility version 1.0.0, current
version 88.3.9)
/usr/lib/libX11.6.dylib ( compatibility version 6.2.0, current
version 6.2.0)
Does that look right?
In the lazarus compiler options under the linking tab I have
-L/Library/Frameworks/SDL.framework -framework carbon sdl
and in the Show Options screen this translates to...
-k-L/Library/Frameworks/SDL.framework -k-framework -kcarbon -ksdl
Which I think all looks fine, but I still get the following error...
/usr/bin/ld: can't open: sdl ( No such file or directory, errno = 2)
Error:Error while linking
This is definitely the location of the framework because I can create an
XCode FreePascal project and that correctly links to SDL.framework in
that directory and I can see a 3D OpenGL spinning cube when it runs.
Thanks,
Dominique.

Dominique,
I don't believe that's the Carbon framework that your apps are using.
Use otool -L against any app compiled against the Carbon framework to
see the framework's location.
Try compiling with the -Cn switch, then look at the link.res text file
generated. This contains the actual switches that are being passed to
the linker.
Thanks.

Hi Philip,
I've just been re-reading your message. So when using frameworks,
there is no need to specify a library name, because the linker resolves
this automagically?
just for clarification the SDL.framework is located @
/Library/Frameworks/SDL.framework.
While I notice that Carbon.framework is located @
/Developers/SDKs/MacOS10.4u.sdk/System/Library/Frameworks/Carbon.framewo
rk
I even tried adding /Library/Frameworks/ to -Fl in the Libraries field
on the Path tab in case that would help, but that did not work either. I
still get the "Can't open : sdl ( No such file or directory, errorno =
2)".
So the compiler recognises that I'm passing a framework via the command
line, but it just can't find it. Is there something else I need to do to
use 3rd Party frameworks?
Dominique.

Dominique,
Did you put the sdl.framework bundle (folder) somewhere that the
linker
can find it? Typically this would be in the Library/Frameworks folder.
If the linker can find the framework it should be able to find any
externally declared functions in your program. You shouldn't need any
link directives in your source either.
Note how it's done in FPCMacOSAll.pas:
function sqrt(x: double_t): double_t; external name '_sqrt';
When you include -framework carbon the linker is able to find the
"_sqrt" function in the Carbon framework's library.
Thanks.

Hi Philip,
Thanks for pointing this out. On the Mac that option was being
hidden due to the dialog size, so I could not see the area where I
needed to put the framework. This is now entered, but I now get a
"Unable to find sdl" error message when it tris to link to the
framework. Is there something else I need to do? Also, if I have
sdl.pas in the project file, it complains that it cant link to
-lSDL-1.2.0 .
If it finds the framework, does it still need to link to it via -l?
Thanks,
Dominique.
Quoting "Hess, Philip J" <[EMAIL PROTECTED]>:
Dominique,
On the Compiler Options tab, check the "Pass Options To The Linker"
box
and enter this in text box: -framework sdl
This will be passed to FPC as -k'-framework' -k'sdl', which then
passes
the switches on to the linker.
Thanks.
-Phil

Subject: [lazarus] Using SDL.framework within Lazaru project
Hi all,
What is the correct way to use an *.framework within a Lazarus
project?
I can get SDL.framework working with XCode, but don't know where put
the -kSDL line to get it to pull in the framework.
Thanks,
Dominique.
