A recent (and even more recently reverted) change to Homebrew highlighted an interesting (read: maddening) quirk of clang on OS X. Here's the background.

Google no longer provides support for older versions than Mac OS X Yosemite 10.10. FAQ Can you install Google Chrome on a Mac? If you want to use Chrome as your default browser, you will need to manually set it to the default browser on your PC as Mac comes out with the Safari web browser pre-installed. Export LDLIBRARYPATH=$LDLIBRARYPATH:$INSTALLDIR/bin:$INSTALLDIR/lib; On Mac OS only, add the following line, replacing $INSTALLDIR as appropriate. Export DYLDLIBRARYPATH=$DYLDLIBRARYPATH:$INSTALLDIR/bin:$INSTALLDIR/lib; Save and close the file. Close and reopen the terminal to activate the changes in your environment.

When you compile something using clang on OS X there are (roughly speaking) two stages to the compile. In the first, your source code is loaded and the compiler searches its include paths to find your includes. Here's what clang's defaults look like for the Xcode 6.4 command line tools:

• The most popular streaming platform for Twitch, YouTube and Facebook. Cloud-based and used by 70% of Twitch. Grow with Streamlabs Open Broadcast Software (OBS), alerts, 1000+ overlays, analytics, chatbot, tipping, merch and more.
• Use a Mac OS X installation Disc. If you're unable to use Internet Recovery Mode or create a bootable USB installer, you can still use a Mac OS X installation disc. These discs are available for OS X Snow Leopard, OS X Lion, and OS X Mountain Lion. If your Mac is from 2012 or earlier, there was an installation disc in the original box.

Today I'm going to tell you a sad tale of a device called the Librem 5 and the company behind it, Purism.As of right now, this story does not have a happy ending. I am writing this series of articles as a protest against the behavior of Purism, a company which claims that transparency and openness are their core values. Late to area 51 (wolverine soft) mac os.

As you can see, the include search starts with /usr/local/include and /usr/include is the fourth item. So, in the case of a vanilla OS X install a binary attempting to compile using OpenSSL (let's say #include ) would find the OpenSSL headers in /usr/include after searching the previous 3 locations fruitlessly.

Once it's found (and the C preprocessor has run and all the objects have been compiled) we now need to link it. When compiling something against OpenSSL you'll link against -lssl, -lcrypto, or both. These command line flags simply tell the linker to look for something named 'libssl.dylib' or 'libcrypto.dylib' in the library search paths. But what are those paths?

The-lost-jedi mac os. This time we see two primary library search paths, /usr/lib and /usr/local/lib…which are reversed in priority from our include search path.

The result of this is that if you have something (like OpenSSL) that is present in both /usr/local/{include,lib} and /usr/{include,lib} you'll end up with the compiler using the headers from /usr/local/include and then linking against the library in /usr/lib. This can result in a variety of problems, the severity of which depend on how different the two versions of the library are and what features the binary you're compiling is using.

So why does this matter? Well, in El Capitan (10.11) Apple has chosen to remove the OpenSSL development headers, but not remove the dylibs. They deprecated use of system OpenSSL in Lion (10.7) so this makes sense on the surface, but the weird include/linker ordering means that if homebrew (or anything else living in your include/search paths) duplicates a system library bad things may occur. There are four possible paths (all of which are under the control of Apple and not us plebes):

• Change the linker order preference. Probably a good idea long term but likely to cause all sorts of unintended breakage as we find things that are implicitly depending on this crazy ordering.
• Re-add the OpenSSL headers for 0.9.8. Not a great option since 0.9.8 is scheduled for EOL at the end of this year and Apple has marked it deprecated in OS X since Lion (originally released July 20, 2011), but probably the safest and lowest friction option.
• Remove OpenSSL entirely. This would break any OS X app that links against it and would require Apple to ship updates to Ruby, Python, Apache, etc that statically link OpenSSL (or go down the route of a 'private' dylib like they've done with OpenSSH in El Capitan)
• Do nothing and let this be a significant source of pain for developers during El Capitan's lifecycle. This is the most likely scenario.

I favor either removing the OpenSSL dylibs entirely for El Capitan or re-adding the OpenSSL headers and then removing everything in the next major release, but I don't envy whoever has to make this choice. Everything has downsides.

In computing, a screen of death is an informal term for a type of computer operating systemerror message, displayed onscreen when the system has experienced a fatal system error. Computer users have dubbed these messages 'screens of death' as they typically result in unsaved work being lost and often indicate serious problems with the system's hardware or software. These error screens are usually the result of a kernel panic, although the terms are frequently used interchangeably. Most screens of death are displayed on an even background color with a message advising the user to restart the computer.

Known screens of death[edit]

• The Blue Screen of Death (also called BSoD, or stop error) is a common name for a screen displayed by the Microsoft Windows operating system when a critical system error occurs. By far, this is the most famous screen of death.
• Two Black Screens of Death are known: One is a failure mode of Windows 3.x. One appears when the bootloader for Windows Vista and later fails.
• The TiVo green screen of death
  A Green Screen of Death is a green screen that appears on a TiVo with a message that includes the words 'the DVR has detected a serious problem and is now attempting to fix it' or 'A severe error has occurred'. Its appearance often means that the hard drive of the device has failed.^[1][2] Blue Screens of Death on the Windows Insider builds of Windows 10 appears as green instead of blue, starting with build 14997.^[3]
• The Purple Screen of Death is used by VMware ESXi, a server virtualization product by VMware, Inc. It is displayed in the event of a fatal kernel error. The screen provides error codes that can be used for debugging purposes.
• Four Red Screens of Death are known: One appears in early beta versions of Windows Vista, but it later became a black screen. Another appeared in Windows 98 and is caused by Advanced Configuration and Power Interface (ACPI). It also appears on the Atari Jaguar System if there is a loading cartridge error or a pirated cartridge is detected, marked by the sound of a roaring jaguar and a red Atari Jaguar logo on a screen that changes color from black to red. And the last one is the PlayStation 2's Red Screen of Death, it is very similar to the PS2 startup screen, except after the startup, a red screen appears with a message saying 'Please insert a PlayStation or PlayStation 2 format disc.' The sound at the start of the Red Screen is actually a low pitched version of PS2 menu screen with a creepy whistle and then the ambient sounds like the menu. This error can be obtained by inserting a non-compatible disc/game disc e.g, a PC disc and later Xbox 360 discs with the new banner.
• A White Screen of Death appears on several other operating systems, content management systems^[4][5] and BIOSes. One is in iOS 7, and the screen of death appears when a white iPhone 5 or later or a white iPod touch (5th generation) is frozen. Everything on the screen goes white, and a black Apple logo is all that's displayed on the screen.^[6]
• A Yellow Screen of Death occurs when an ASP.NET web app encounters a problem and crashes.^[7]
• A kernel panic is used primarily by Unix and Unix-like operating systems: the Unix equivalent of Microsoft's Blue Screen of Death. It is a routine called when the kernel detects irrecoverable errors in runtime correctness; in other words, when continued operation may risk escalating system instability, and a system reboot is easier than attempted recovery.
• A Sad Mac is a symbol used by older-generation Apple Macintosh computers, starting with the original Macintosh 128K, to indicate a severe hardware or software problem that prevented startup from occurring successfully. A similar symbol exists for the iPod.
• A Sad Tab is an icon displayed on a tab in Google Chrome when that tab crashes. The symbol is similar to that of the Sad Mac.
• The Bomb icon is a symbol that was displayed when a classic Mac OS program had an application crash. The bomb symbols were also used by the Atari ST line of computers when the system encountered a fatal system error. The number of bombs indicated the exact cause of the error.
• Guru Meditation is the name of the error that occurred on early versions of the Amiga computers when they crashed. It was also used on the Nintendo DS, most commonly seen when using homebrew. (The top screen was black, and the bottom screen was red with white debug font saying 'Guru Meditation Error! data abort!' with some hex addresses below it.)
• PowerMax crashes happen when the computer fails to turn on correctly. it will say -the system could not turn on correctly, the system will need to reset- .
• Kernel Debug Land is the name of the Kernel Debugger users of Haiku/BeOS are dropped into when a kernel crash is experienced.
