Re: [Bug-apl] libapl load problem....

[Peter Teeson]

I’ve been thinking about this and I believe it’s probably because libapl.so is C++ but Cocoa is Obj-C.

Pure C plays nicely with Obj-C but there needs to be wrappers for C++ to play nicely with Obj-C.

So while I wait for your wise replies I will research what to do to use C++ dlls in Obj-C; I don’t even know if that is possible.

Hi all:

The following is for svn 1048 ./configure —with-android —with-libapl

Using MacOS Yosemite 10.10.5 and Xcode 6.4 and a vanilla Cocoa Document app.

In the AppDelegate code I have the following:

void *libaplHandle; // plain C file pointer

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {

    // Load libapl from default location.

    const char* libaplPath="/usr/local/lib/apl/libapl.so"; // TO DO Make this path a User Preference....}

    libaplHandle = dlopen(libaplPath, RTLD_LAZY|RTLD_GLOBAL);

    if (NULL == libaplHandle) {

        char *error = dlerror();

        printf("AppDelegate - dlopen(libaplHandle) error: %s",error);

    }

}

AppDelegate - dlopen(libaplHandle) error: dlopen(/usr/local/lib/apl/libapl.so, 9): Symbol not found: _CERR

  Referenced from: /usr/local/lib/apl/libapl.so

  Expected in: flat namespace

 in /usr/local/lib/apl/libapl.so

I really have no idea why this happens. Please educate me…..

Thanks and

respect…..
