Oracle Virtualbox crashing (aborting) on macOS [Solved]

 I run into issues every time I update my VirtualBox version on my MacBook Pro. If you run into issues where you can't start a VM instance, try this fix.

Open Virtualbox >> Go to your VM image >> Click on Settings >> Go to Audio >> Uncheck the "Enable Audio" box.

[Solved] 'cryptopp/aes.h' file not found; Expected namespace name

If you are facing errors like "'cryptopp/aes.h' file not found" or getting "Expected namespace name" error for "using namespace CryptoPP;" or similar compilation errors, refer to the following settings:

• Add "/usr/local/include" in Header search paths
• Add "/usr/local/lib" in Library search paths
• Add -lcryptopp as a Linker flag

Refer to this article for more information: https://com.puter.tips/2021/02/how-to-use-cryptopp-in-xcode.html

[How To] Use Boost in Xcode

Using Boost C++ Libraries (https://www.boost.org/) is relatively easier than setting up Cryptopp. [Ref.: https://com.puter.tips/2021/02/how-to-use-cryptopp-in-xcode.html]

Step-1: Install boost libraries

$ brew install boost

Step-2: Link boost in Build Settings

• Navigate to Linking >> Other Linker Flags
• Add following flags as per your requirement
• -lboost_chrono
• -lboost_system
• -lboost_timer
• -lboost_regex

[Solved] code signature not valid for use in process using Library Validation

So I was working on a C++ project on Xcode, and I updated to the latest version of Xcode with recommended default settings; then I started having the following errors:

dyld: Library not loaded: /usr/local/lib/libcryptopp.dylib

  Referenced from: /Users/devharsh/Library/Developer/Xcode/DerivedData/server-bohvcuztzndrrzhcoglrvuijfasj/Build/Products/Debug/server

  Reason: no suitable image found.  Did find:

/usr/local/lib/libcryptopp.dylib: code signature in (/usr/local/lib/libcryptopp.dylib) not valid for use in process using Library Validation: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed.

/usr/local/lib/libcryptopp.dylib: code signature in (/usr/local/lib/libcryptopp.dylib) not valid for use in process using Library Validation: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed.

/usr/local/lib/libcryptopp.dylib: code signature in (/usr/local/lib/libcryptopp.dylib) not valid for use in process using Library Validation: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed.

Program ended with exit code: 9

Solution:

• Go to Xcode > Targets > Build Settings
• Scroll down and go to the Signing tab
• Click on "Enable Hardened Runtime" and set it to "No"
• Recompile, and it should be fixed
