IntelliSense doesn't recognize TObjectPtr as Pointers, TArray member functions

[reDBo0n]

Created a new UE5.1 First Person Project with the Epic Games provided Linux binaries (here). Added the following code block (to the Constructor of the Character)

TArray<USkeletalMeshComponent*> TestArray;
TestArray.AddUnique(Mesh1P);

TObjectPtr<USkeletalMeshComponent> TestPtr = Mesh1P;
if(TestPtr){
    TestPtr->SetOnlyOwnerSee(true);
}
Mesh1P->SetOnlyOwnerSee(true);

Following "errors" got marked by IntelliSense, although the code compiles just fine:

• class "TArray<USkeletalMeshComponent *, FDefaultAllocator>" has no member "AddUnique"
• no suitable constructor exists to convert from "USkeletalMeshComponent *" to "TObjectPtr"
• expression must have bool type (or be convertible to bool)
• operator -> or ->* applied to "TObjectPtr" instead of to a pointer type

I reset the Database, refreshed the project, tried with and without the "Optional Fixes"

Got 2 times the same Warning

Warning : Epic Games has included 199 paths that don't exist. Is this on purpose? No invalid paths returned. No fixes needed.

You can ignore that warning.

I did get the same bug with Intellisense on Ubuntu. The bug isn't there with Windows using cl. Looking into it.

I was able to get it to work by using 13.0.1 from the llvm download page instead of the clang++ that comes with UE5.

https://stackoverflow.com/questions/17045954/how-to-install-clang-using-precompiled-binaries

I commented out the first two commands because I just downloaded the tarball from the website: https://github.com/llvm/llvm-project/releases/tag/llvmorg-13.0.1

Even though I was on 22.04 I downloaded clang+llvm-13.0.1-x86_64-linux-gnu-ubuntu-18.04.tar.xz

I extracted the contents. Created a new directory called ~/llvm_13.0.1 Then did a simple copy of the extracted contents to this new directory.

So llvm_13.0.1 should now have directories called bin,lib, etc.

I don't know if the other 2 steps are required but I did them. You also might want to add the export PATH=/home/s/bin:$PATH step permanently because it will go away once you close the terminal.

Note: This example uses 's' as the parent directory but I used llvm_13.0.1

# wget <clang-binaries-tarball-url>
# sudo tar -xf <clang+llvm-..tar.xz> --strip-components=1 -C /home/s  

# Set the path environmental variable  
export PATH=/home/s/bin:$PATH

# Tell ldconfig about new shared library in /home/s/lib
cd /home/s
cat > libs.conf << "END"
/home/s/lib
END

sudo mv libs.conf /etc/ld.so.conf.d/libs.conf
sudo ldconfig

I also had to add a clang dependency by using this command: sudo apt install libncurses5

I had to change the compiler path in my extension settings in VSCode. /home/yourUserName/llvm_13.0.1/bin/clang++

After you change the compiler path restart VSCode and it'll ask you which path you want to use. Choose the new one you just changed to.

Woops, I actually didn't test your code. I tested a simple TArray example and it was able to see all the TArray functions. Your code should still work with intellisense now though. I'll test it later to be sure.

[boocs]

Test the new Intellisense compiler with your code and all the Intellisense errors are gone.

[reDBo0n]

Yeah can confirm.

Changed the compiler inside the extension to my distro clang++ and it worked.
