Im working in kext, For socket filtering when i use sflt_register it failed to load by saying.
_sflt_register symbol is unresolved for this kext. (libkern/kext) link error.
Please help.
Have you run the kextlibs command on your kext? You're probably missing the BSD kpi from your list of dependencies in the Info.plist.

I create a post today because I have a problem with the blackfire installation.
I read all documentation and install this extension but I have an error message in my command consol.
I did add BlackFire but when I want to config the extension, this message appair :
Warning: PHP Startup: Unable to load dynamic library 'blackfire' (tried: D:/Programmes/WAMP/bin/php/php7.3.12/ext/blackfire (The specified module was not found.), D:/Programmes/WAMP/bin/php/php7.3.12/ext/php_blackfire.dll (The specified module was not found.)) in Unknown on line 0[enter image description here]
I'm sure as a good path and I don't understand why I have this message..
If you can help me,
Thanks in advance and good development !
I have an XCode project that builds with the legacy build system, but when using the new build system under xcode11 immediately fails with the err:
.. forcing incremental PIF cache clear after loading error: Required key 'productTypeIdentifier' is missing in StandardTarget dictionary
note: Using new build system
error: Build service could not start build operation: unknown error while handling message: MsgHandlingError(message: "no PIF transfer has been initiated")
I'm looking for any info that might help clarify this.
What is a 'StandardTarget dictionary'? Can I add the missing key directly? Or is this a consequence some other setting?
Are there any 'PIF transfer' experts out there?
I am trying to setup a network in the container (using Docker's libnetwork and libcontainer), but I keep running into this issue. As far as I can tell it's looking into some_app to get some sandbox information?

I was wondering if anyone could help me make sense of this and perhaps prevent it. Are these two separate errors?
Thank you
Here is the library I am trying to use
It took me a while to figure this out, but here goes:
Just like in Docker, libnetwork creates a veth interface pair. It then moves one end of the veth pair into the container namespace. During this process libnetwork tries to execute commands registered at runtime on the current instance of the binary (some_app in this case).
These commands do not exist on the external interface of some_app however. They are injected later using a library called reexec. For this to work, reexec needs to be initialized like this:
if reexec.Init() {
return
}
Also note that according to this thread libnetwork is currently not supported for applications outside of Docker.
NB: I discovered this by reading the source code, so I might be wrong but my issue went away after this.
I am configuring h323 with freeswitch but while loading mod_h323 module in freeswitch getting below error.
CRIT] switch_loadable_module.c:1520 Error Loading module /usr/local/freeswitch/mod/mod_h323.so
**/usr/local/freeswitch/lib/libh323_linux_x86_64_.so.1.26.5: undefined symbol: _ZN18H235Authenticators19GetEncryptionPolicyEv*
Please anyone knows how to fix this error ?
this is well known problem while compiling some of the module in freeswitch.reason for this can be one of these
1. Ptlib and H323plus need is not configured properly or installed correctly
2. package config is not configured to pc files
so for that
1. first check your library required for h323 is installed correctly and location for the same
2. find .pc file
3. configure pkg config path to that library
I'm getting this error on my latest (and first) AOSPA build for lt01wifi.
It happens when I try to open Browser but it crashes before it opens.
Error Log:
I/LibraryLoader( 5999): Loading: webviewchromium
E/ActivityThread( 5999): Failed to find provider info for com.google.settings
E/dalvikvm( 5999): dlopen("/system/lib/libwebviewchromium.so") failed: dlopen failed: empty/missing DT_HASH in "libwebviewchromium.so" (built with --hash-style=gnu?)
E/WebViewFactory( 5999): error instantiating provider
E/WebViewFactory( 5999): java.lang.RuntimeException: Cannot load WebView
Probably it is the .so file itself that is the problem.
It was built with --hash-style=gnu, which is not supported in Android platform.
You should build your .so file again.
And this link could be helpful.
