You can use the source code from a standard checkout of the llvm-project(as described above) to do stand-alone builds, but you may also buildfrom a sparse checkout or from thetarballs available on the releasespage.
GNU Binutils 2.19.1 Gold: This version of Gold contained a bug which causesintermittent failures when building LLVM with position independent code. Thesymptom is an error about cyclic dependencies. We recommend upgrading to anewer version of Gold.
Download C Project With Source Code
If you have the LLVM distribution, you will need to unpack it before you canbegin to compile it. LLVM is distributed as a number of differentsubprojects. Each one has its own download which is a TAR archive that iscompressed with the gzip program.
Once checked out repository, the LLVM suite source code must be configuredbefore being built. This process uses CMake. Unlinke the normal configurescript, CMake generates the build files in whatever format you request as wellas various *.inc files, and llvm/include/Config/config.h.
The result of such a build is executables that are not runnable on the buildhost but can be executed on the target. As an example the following CMakeinvocation can generate build files targeting iOS. This will work on macOSwith the latest Xcode:
Build products are named using one of the following templates: sqlite-product-version.zip sqlite-product-version.tar.gz sqlite-product-os-cpu-version.zip sqlite-product-date.zipTemplates (1) and (2) are used for source-code products. Template (1) isused for generic source-code products and templates (2) is used for source-codeproducts that are generally only useful on unix-like platforms. Template (3)is used for precompiled binaries products. Template (4) is used forunofficial pre-release "snapshots" of source code.The version is encoded so that filenames sort in order ofincreasing version number when viewed using "ls". For version 3.X.Y thefilename encoding is 3XXYY00. For branch version 3.X.Y.Z, the encoding is3XXYYZZ.The date in template (4) is of the form: YYYYMMDDHHMMFor convenient, script-driven extraction of the downloadablefile URLs and associated information, an HTML comment is embeddedin this page's source. Its first line (sans leading tag) reads:Download product data for scripts to readIts subsequent lines comprise a CSV table with this column header:PRODUCT,VERSION,RELATIVE-URL,SIZE-IN-BYTES,SHA3-HASHThe column header and following data lines have no leading space.The PRODUCT column is a constant value ("PRODUCT") for convenientregular expression matching. Other columns are self-explanatory.This format will remain stable except for possible new columnsappended to the right of older columns.Source Code RepositoriesThe SQLite source code is maintained in three geographically-dispersedself-synchronizingFossil repositories that areavailable for anonymous read-only access. Anyone can view the repository contents and download historical versionsof individual files or ZIP archives of historical check-ins.You can also clone the entire repository.
See the How To Compile SQLite page for additional informationon how to use the raw SQLite source code.Note that a recent version of Tclis required in order to build from the repository sources. The amalgamation source code files(the "sqlite3.c" and "sqlite3.h" files) build products and arenot contained in raw source code tree.
When you wrap your build command with the Build Wrapper, it will run the given command and gather all the configuration required for a correct analysis of C/C++/Objective-C projects such as macro definitions and include directories. The Build Wrapper does not impact your build; it merely monitors it and writes what it learns into files in a directory you specify.
By default, the reporting standard version is the version that is used to compile the code. This is ideal for most projects. However, there are some edge cases where there is a need to use a reporting standard that is different from the compilation standard. For this reason, we provide the following scanner property to adjust the reporting standard:
When you have a Solution made of C++ and C#, in order to both use the Build Wrapper and have an accurate analysis of the C# code, you must use the SonarScanner for MSBuild. The SonarScanner for MSBuild does not handle sonar-project.properties files, so the Build Wrapper output directory will have to be set during the MSBuild begin step.
To develop C programs, there are two things that we need:First, we need a code editor - this is the program that we will use to write our source code (a source code file is simply a text file, which has a ".c" extension, and which contains valid C code).
Secondly, we need a C compiler - this is a program that converts the source code we have written into an executable file that we can run.
In this case, "runme" is the name of the executable file that will be created if your code compiles successfully, and "hello.c" is the name of the source file.In the screenshot below, you can see that a new file called "runme" was created in the same directory as the source file.
OK, let's go ahead and compile our first very simple C program using the gcc compiler. We will use a basic text editor to write the source code, and the commands for compiling and running the program are illustrated below:
Now that we have installed the command line tools, let's install a powerful (and free) code editor called Visual Studio Code. We will use this editor to write the source code for our programs. In addition, Visual Studio Code has an "Integrated Terminal" feature which means we can compile and run our program without leaving the Visual Studio Code environment.
The integrated terminal pane will appear inside the Visual Studio Code environment. In the screenshot below, the terminal pane appears underneath the source code. You can type the same commands in this integrated terminal as you can type from the regular Terminal window - as shown, the source file has been compiled and executed. The output appears directly in the terminal pane.
We recommend that developers who want the fastest incremental builds use theNinja build system. You can use thegenerated Visual Studio project files to edit Clang source code and generate asecond build directory next to it for running the tests with these steps:

cloc counts blank lines, comment lines,and physical lines of source code in many programming languages.Given two versions of a code base, cloc can computedifferences in blank, comment, and source lines.It is written entirely in Perl with no dependencies outside thestandard distribution of Perl v5.6 and higher (code from some external modules is embedded within cloc)and so is quite portable.cloc is known to run on many flavors of Linux, FreeBSD,NetBSD, OpenBSD,Mac OS X, AIX, HP-UX, Solaris, IRIX, z/OS, and Windows.(To run the Perl source version of cloc on Windows one needs ActiveState Perl5.6.1 or higher, Strawberry Perl, Cygwin, or MobaXTerm withthe Perl plug-in installed.Alternatively one can use the Windows binary of cloc generated with PAR::Packer to run on Windows computers that have neither Perl nor Cygwin.)
Although cloc does not need Perl modules outside those found in the standard distribution, cloc does rely on a few external modules.Code from three of these external modules--Regexp::Common,Win32::Autoglob, and Algorithm::Diff--is embedded within cloc. A fourth module,Digest::MD5, is used only if it is available.If cloc finds Regexp::Common or Algorithm::Diffinstalled locally it will use thoseinstallation. If it doesn't, cloc will install the partsof Regexp::Commonand/or Algorithm:Diffit needs to temporary directories that are createdat the start of a cloc run then removed when the run is complete. The necessary code from Regexp::Common v2.120 andAlgorithm::Diff v1.1902 are embedded withinthe cloc source code (see subroutinesInstall_Regexp_Common() andInstall_Algorithm_Diff() ).Only three lines are needed from Win32::Autoglob and these areincluded directly in cloc.
The default Windows download, cloc-1.64.exe, was built with PAR::Packer on a Windows 7 computer with Strawberry Perl. Windows executables of cloc versions 1.60 and earlier were built withperl2exeon a 32 bit Windows XP computer. A small modification was madeto the cloc source code before passing it to perl2exe; lines 87 and88 were uncommented:85 # Uncomment next two lines when building Windows executable with perl2exe86 # or if running on a system that already has Regexp::Common. 87 #use Regexp::Common;88 #$HAVE_Rexexp_Common = 1;
Otherwise,to build a Windows executable with pp from PAR::Packer,first install a Windows-based Perl distribution (for exampleStrawberry Perl or ActivePerl) following their instructions. Next, opena command prompt, aka a DOS window and install the PAR::Packer module.Finally, invoke the newly installed pp command with thecloc souce code to create an .exe file:C:> perl -MCPAN -e shellcpan> install PAR::Packercpan> exitC:> pp cloc-1.64.plA variation on the above is if you installed the portable versionof Strawberry Perl, you will need to run portableshell.batfirst to properly set up your environment. The Strawberry Perlderived executable on the SourceForge download area was createdwith the portable version on a Windows 7 computer.
Languages with file extension collisions are difficult tocustomize with --read-lang-def or--force-lang-def as they have no mechanism to identify languages with common extensions. In thissituation one must modify the cloc source code.
cloc's method of operation resembles SLOCCount's: First, createa list of files to consider. Next, attempt to determine whether or notfound files contain recognized computer language source code. Finally, for files identified as source files, invoke language-specific routinesto count the number of source lines. 2ff7e9595c
