DESCRIPTION
ERROR: ld.so: object 'libfakeroot-sysv.so' from LD_PRELOAD cannot be
preloaded (cannot open shared object file): ignored. USAGE:
clang-check [options] <source0> [... <sourceN>]
OPTIONS:
General options:
-help - Display available options (-help-hidden
for more)
-help-list - Display list of available options
(-help-list-hidden for more)
-version - Display the version of this program
clang-check options:
-analyze - Run static analysis engine
-ast-dump - Build ASTs and then debug dump them
-ast-dump-filter=<string> - Use with -ast-dump or -ast-print to
dump/print only AST declaration nodes having a certain substring
in a qualified name. Use -ast-list to list all filterable
declaration node names.
-ast-list - Build ASTs and print the list of
declaration node qualified names
-ast-print - Build ASTs and then pretty-print them
-extra-arg=<string> - Additional argument to append to the
compiler command line
-extra-arg-before=<string> - Additional argument to prepend to the
compiler command line
-fix-what-you-can - Apply fix-it advice even in the presence
of unfixable errors
-fixit - Apply fix-it advice to the input source
-p=<string> - Build path
-p <build-path> is used to read a compile command database.
For example, it can be a CMake build directory in which a file
named compile_commands.json exists (use
-DCMAKE_EXPORT_COMPILE_COMMANDS=ON CMake option to get this
output). When no build path is specified, a search for
compile_commands.json will be attempted through all parent paths
of the first input file . See:
http://clang.llvm.org/docs/HowToSetupToolingForLLVM.html for an
example of setting up Clang Tooling on a source tree.
<source0> ... specify the paths of source files. These paths are
looked up in the compile command database. If the path of a file
is absolute, it needs to point into CMake's source tree. If the
path is relative, the current working directory needs to be in
the CMake source tree and the file must be in a subdirectory of
the current working directory. "./" prefixes in the relative
files will be automatically removed, but the rest of a relative
path must be a suffix of a path in the compile command database.
For example, to run clang-check on all files in a subtree of the
source tree, use:
find path/in/subtree -name '*.cpp'|xargs clang-check
or using a specific build path:
find path/in/subtree -name '*.cpp'|xargs clang-check -p
build/path
Note, that path/in/subtree and current directory should follow
the rules described above.

The full documentation for clang-check is maintained as a Texinfo
manual. If the info and clang-check programs are properly installed at
your site, the command
info clang-check
should give you access to the complete manual.
Opportunity
Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.
Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.
Free Software
Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.
Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.
Free Books
The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.
Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.
Education
Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.
Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
