Usr used to mean вЂњeverything user-related,вЂќ but this has evolved into вЂњuser usable programs and data over time.вЂќ This means that the usr contains shareable, read-only data, and often contains the largest share of behind-the-scenes data on any operating system. The same is true of usr and var and other folders and directories. As a general rule, exposing anything that could negatively impact a building if it was accidentally damaged or tampered with is considered a good idea. When buildings are constructed, wiring and plumbing are hidden behind walls.

Unlike Applications or Documents or Downloads, some files and folders are hidden by default by the Mac operating system (macOS). But to help you do it all by yourself, weвЂ™ve gathered our best ideas and solutions below.ДЇeatures described in this article refer to the MacPaw site version of CleanMyMacВ X.ДЄpple operating systems are constructed using a Linux file system hierarchy, which means that traditional UNIX system directories hide certain files and directories.

Ln -s /usr/local/Cellar/openssl/1.0.So here's a tip for you: Download CleanMyMac to quickly solve some of the issues mentioned in this article. Ln -s /usr/local/Cellar/openssl/1.0.2o_1/include/openssl /usr/local/include/openssl I ended up deleting Xcode from the Applications directory, which resulted in xcode-select -p returning /Library/Developer/CommandLineTools.

When I ran xcode-select -p, it showed /Applications/Xcode.app/Contents/Developer.

#Mac usr local install

The command returned with xcode-select: error: command line tools are already installed, use 'Software Update' to install updates. I have Yosemite 10.10.5 and running xcode-select -install didnвЂ™t fix the problem for me. The command-line tools seem to resolve this issue. One symptom is that /usr/local/include is not on the include search path. 3:ДЄt least on Mavericks, IвЂ™ve found that if I install the Xcode application without installing the command-line tools, then the tools are sort of available, but normal unix-ey builds donвЂ™t work correctly. If you want to check exactly what folders your compiler is looking through for header files you can write:ДЄ workaround would be to: export C_INCLUDE_PATH=/usr/local/includeД®xport CPLUS_INCLUDE_PATH=/usr/local/includeДЄt least this tricked the pre-processor to behave here рџ™‚ Solution no. I donвЂ™t know why Homebrew doesnвЂ™t automatically check this upon installation, since it does check for XcodeвЂ¦ This installs the command-line tools that also create /usr/lib/ and /usr/include/. Note that it doesnвЂ™t work without the double hyphens given by the previous answer.

I also use Homebrew and had a similar problem on Mac OSX Maverick 10.9.5 and Xcode 6.0.1, but it was solved by running:

IвЂ™m on OS X 10.9.3 with Xcode 5.1.1 in case it is relevant. Is there a way for me to get g++ to acknowledge the stuff in /usr/local by default? Is there a standard way homebrew users do this? So the only issue seems to be that g++ fails to acknowledge /usr/local.Д«ut it is tedious to type all this out all the time, especially when IвЂ™m just writing small single file programs. So then I explicitly told g++ to use /usr/local/lib Kyumins-iMac:gcjlib math4tots$ g++ main.cpp -lgmp -lgmpxx -I/usr/local/include -L/usr/local/lib
