Dynamic Librarys (dylibs)

[SEO]

First, sorry for the 'jumping' in the threads!
Not nice, therefore I created this new thread for dylibs Questions, and hope answers.
-----------------------------------

I compiled my SampleDylib and use the code:

Code: Select all

If OpenLibrary(0, "SampleDylib.dylib") 
  FunctionPointer = IsFunction(0, "addFunction") 
  If FunctionPointer 
    x = CallFunctionFast(FunctionPointer, 10,5) 
Debug x
  EndIf 
EndIf

I get Line 2: Syntax Error ! (FunctionPointer = IsFunction(0, "addFunction")

Any ideas?

I just try it here and it seems to work, could you test it again with the registered version ?

[SEO]

Yes I should (Have not doing that)

[SEO]

Nope!
Line 2 Syntax Error!

I have the SampleDylib.dylib in the same folder that the PB source file when I run from IDE. Is PB created some temporary bundle?

C code:

Code: Select all

int addFunction( int a, int b ) {
      return a + b;
  }


  int stringLength( char *str ) {
      return strlen(str);
  }

the syntax error is very wierd. could you try to retype it in a new source (don't copy/paste) ?

[SEO]

YEP!!

Then I get the same error on next line and so on.
But I cleanup and use new carrige returns in the code.

And then it works!

Sorry, it looks not work inside the bundle.

I tested some 'paths' /dsd/sds/SampleDylib.dylib
and inside the MacOs folder and as 'absolutepath on the desktop, but no...

This have NOT prioritet 10 only 1-2 ...

If fond some strange or perhaps i do some wrong...

As I wrote I DON'T get Dylibs to works and today I have this problem, that could Explain also why Dylibs not working inside the bundle.

Code: Select all

Result = LoadImage(tb1ico,"Resources/Toolbaricons/tbico1.png")

It looks that nothing works when I use to call something that is inside an folder. The Result = 0

And is this also the reason why the PB Example Project Toolbar.pb NOT was in the Mac Example Folder ???

This is a good question, should all the filesystem paths be relative to the bundle (ie: current directory set to the bundle path) by default ? If yes, it shouldn't be a problem to change (for your tests you can still use an absolute path).

Hi and thanks for the response!

Absolute paths on Mac is DEVIL! Criminal and forbidden... That is my an many Mac users opinion. That is beacuse you could move an file to an another folder or harddisk and Mac file system is following your file. So it find it also when you moved it.

Absolute paths are only used to display where the file is located .. like in an Window title ....


About the bundle: The file should be relative to the executable, you could not use an 'absolute path', what happens if you move your application bundle ? When an user download an application, he could use it every where... And how do I know as an developer of the app where he put his application?


My second test with the Toolbar...
I could not use something like this LoadImage "folder1/folder2/image.png"

Hi again,

I post this example how it works in an another language ...
or could work....

myPath$ = GetPath("") // This give the Executable (CurrDir)

Here opening an text file inside the bundle
myPath$ = GetPath("").child("folder1").child(folder2").child("textfile.txt")

So if my bundle is on the desktop folder i could address desktop folder like this:


myPath$ = getPath("")
myPath$ = myPath$.parent
or like this myPath$ = getPath(..)

Now myPath$ = desktopFolder

I mean for your tests you could use an absolute path, not for release ! To test it: LoadImage(0, "/Users/yourlogin/test.png"). About the bundle currentdir by default, it makes sens, so i will do this change. About the command to retrieve the executable path, it will be done as well.

It's a taste of Christmas ....
