I want to compile llvm on ubuntu follow git wiki:
$ git clone -b llvm-4.0 https://github.com/obfuscator-llvm/obfuscator.git
$ mkdir build
$ cd build
$ cmake -DCMAKE_BUILD_TYPE=Release ../obfuscator/
When I execute cmake -DCMAKE_BUILD_TYPE=Release ../obfuscator/,report ab error:

I'm trying to build doxygen from source, with MSYS2.
I've installed make, bison, flex, and libiconv using the command $ pacman -S <package> and I've installed gcc, cmake and ninja using the explicit environment naming, e.g. $ pacman -S mingw-w64-ucrt-x86_64-<package>.
The build procedure:
git clone https://github.com/doxygen/doxygen.git
cd doxygen
mkdir build
cd build
cmake -G "MSYS Makefiles" ..
make
I'm getting 24% ready without warnings, but when building portable.cpp I get errors. The CMakeError.log shows two failures:
Determining if the function iconv_open exists failed
Performing C++ SOURCE FILE Test ICONV_ACCEPTS_CONST_INPUT failed
I've tried to install the iconv library using both the short libiconv name and the mingw-w64-ucrt-x86_64-iconv name.
I have MacOS Catalina, Cmake, Ninja and QtCreator installed with the following versions and paths:
[#bin]$ sw_vers -productVersion
10.15.6
[#bin]$ which cmake
/usr/local/bin/cmake
[#bin]$ cmake --version
cmake version 3.18.2
CMake suite maintained and supported by Kitware (kitware.com/cmake).
[#bin]$ which ninja
/usr/local/bin/ninja
I'm trying to build a project with QT creator using Cmake. However, the following message appears in QT Creator

As indicated on several websites (such as this SO question I tried the following command but it didn't work:
[#bin]$ ln -s /usr/bin/ninja /usr/bin/ninja-build
ln: /usr/bin/ninja-build: Operation not permitted
As indicated in the comments I tried also the following:
[#bin]$ sudo ln -s /usr/bin/ninja /usr/bin/ninja-build
Password:
ln: /usr/bin/ninja-build: Operation not permitted
I also tried:
[#bin]$ sudo ln -s /usr/bin/ninja /usr/local/bin/ninja-build
It didn't cause any error message but the problem in QT creator persisted
I'm trying to build https://github.com/AlbertWerner/cryptonotecoinwallet and facing an issue.
According to the README of the repo, I can run cmake command and it completes without any errors. But then, when I run make, it gives me the below error.
$ make
make: /usr/bin/cmake: Command not found
make: *** [Makefile:5138: cmake_check_build_system] Error 127
I'm using MSYS on Windows and here are the corresponding details.
$ echo $PATH

$ which cmake
/mingw32/bin/cmake
Seems like it's looking for cmake in the wrong path.
Makefile
cmake_check_build_system:
$(CMAKE_COMMAND) -H$(CMAKE_SOURCE_DIR) -B$(CMAKE_BINARY_DIR) --check-build-system CMakeFiles/Makefile.cmake 0
.PHONY : cmake_check_build_system # <== Line 5139
I'm not sure what's wrong. Please help me out.
Thanks.
Make sure that you launch MSYS2 using the mingw32.exe executable at the top level of your MSYS2 installation, and that you use that environment when you first run cmake. If you ran CMake in a different environment, remove all the files it created. The commands for running cmake and building the project should be something like this, assuming the developers have set it up in a reasonable way:
mkdir build
cd build
cmake .. -G"MSYS Makefiles"
make
I didn't try this myself because I am wary of running random code from the internet, but I found this note in the CMakefile indicating that the developers do not support MSYS2:
if (WIN32)
if (NOT MSVC)
message(FATAL_ERROR "Only MSVC is supported on this platform")
endif ()
...
So you will have to spend some effort on porting the Windows-specific code in this program to GCC if you really want to do this.
I've tried to build clang-tidy from sources but it complains about an undefined CMake command:
CMake Error at clang-apply-replacements/CMakeLists.txt:5 (add_clang_library):
Unknown CMake command "add_clang_library".
CMake Warning (dev) in CMakeLists.txt:
No cmake_minimum_required command is present. A line of code such as
cmake_minimum_required(VERSION 3.9)
should be added at the top of the file. The version specified may be lower
if you wish to support older CMake versions for this project. For more
information run "cmake --help-policy CMP0000".
This warning is for project developers. Use -Wno-dev to suppress it.
-- Configuring incomplete, errors occurred!
How can I build clang-tidy or, alternatively, how can I install the latest version on macOS?
Up-to-date steps:
git clone https://github.com/llvm/llvm-project.git
cd llvm-project
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra" ../llvm
make install clang-tidy
Reference, ninja, and other details: my own blog post.
EDIT: this answer is out of date — the LLVM project has moved to a single git repository at https://github.com/llvm/llvm-project. See answers below for updated instructions.
clang-tidy is intended to be built inside a checkout of llvm/clang, and depends on CMake macros from the llvm project. You should check out the llvm repo, then the clang repo inside llvm/tools/clang, then the clang-tools-extra repo inside llvm/tools/clang/tools/extra. Then you can run CMake on the top-level directory, and make clang-tidy should work.
If you're not interested in building it yourself, it looks like the Homebrew formula for LLVM also includes the extra tools: https://github.com/Homebrew/homebrew-core/blob/382d3defb5bc48ce2dccd17261be70c4ada9a124/Formula/llvm.rb#L181
I had same problem as Per Mildner. Got is solved with slightly modified code YvesgereY posted (I don't have enough reputation to post a comment to that answer, hence a new answer instead).
In short, I added -G "Unix Makefiles" to cmake. Without this option, no makefile will be generated. Also, I used -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra;". It didn't work when just clang-tools-extra was specified.
Here is the whole snippet:
git clone https://github.com/llvm/llvm-project.git
cd llvm-project
mkdir build
cd build
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=RelWithDebInfo -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra;" ../llvm
make -j8 install-clang-tidy
#jtbandes: Thank you for the information.
I'd like to share these explicit steps for us noobs:
1. Download the released sources from LLVM Download Page
LLVM source code -> Links to the file llvm-6.0.0.src.tar.xz
Clang source code -> Links to the file cfe-6.0.0.src.tar.xz
clang-tools-extra -> Links to the file clang-tools-extra-6.0.0.src.tar.xz
2. Detar each of these into the proper directory:
$ tar -zxvf <download_dir_path>/llvm-6.0.1.src.tar.xz
$ cd llvm-6.0.1.src/tools
$ tar -zxcf <download_dir_path>/cfe-6.0.1.src.tar.xz
$ cd llvm-6.0.1.src/tools/cfe-6.0.1.src/tools
$ tar -zxvf <download_dir_path>/clang-tools-extra-6.0.1.src.tar.xz
Results in a directory llvm-6.0.1.src/tools/cfe-6.0.1.src/tools/clang-tools-extra-6.0.1.src/clang-tidy; Which is incorrect. The lang-tools-extra-6.0.1.src needs to be renamed to extra (as mentioned by #jtbandes).
3. So rename it or provide a symbolic link:
$ cd llvm-6.0.1.src/tools/cfe-6.0.1.src/tools
$ mv clang-tools-extra-6.0.1.src extra
or
$ ln -s clang-tools-extra-6.0.1.src extra
The path llvm-6.0.1.src/tools/cfe-6.0.1.src/tools/extra/clang-tidy should now be valid
4. Build it:
$ cd llvm-6.0.1.src
$ mkdir build
$ cd build
$ cmake ..
$ make
Everything should make without errors or warnings.
5. Build Output:
The build output can be found in llvm-6.0.1.src/build/bin.
For everyone who are looking for latest (LLVM 11) Windows build instructions (ensure CMake, Visual Studio 2019 and git are installed and set in PATH):
git clone --config core.autocrlf=false https://github.com/llvm/llvm-project.git
cd llvm-project
mkdir build
cd build
cmake -G "Visual Studio 16 2019" -Thost=x64 -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra" ../llvm
cmake --build . --target clang-tidy --config RelWithDebInfo --parallel
cmake --build . --target clang-query --config RelWithDebInfo --parallel
This worked for me:
mkdir build
files="
llvm-12.0.1.src.tar.xz
clang-12.0.1.src.tar.xz
clang-tools-extra-12.0.1.src.tar.xz
"
for f in $files; do
echo "Untar $f"
tar xf $f
done
mv llvm-12.0.1.src llvm
mv clang-12.0.1.src llvm/tools/clang
mv clang-tools-extra-12.0.1.src llvm/tools/clang/tools/extra
cd build
cmake -G "Unix Makefiles" \
-DCMAKE_BUILD_TYPE=Release \
-DCMAKE_INSTALL_PREFIX=/usr/local/llvm \
-DCLANG_BUILD_TOOLS=ON \
../llvm
make -j16 install
As of LLVM 14.0.0, sparse checkouts do no longer work (at least temporarily) and the top-level directory contains no CMakeLists.txt. I believe the tree layout has changed after LLVM 13.0.1. In consequence, none of the approaches here worked without quite some modification.
Here is how you can build version 15.0.0git (the most recent at the time of this writing). See related issue: https://github.com/llvm/llvm-project/issues/53281.
First, get the compressed code or clone with git (slower)
$ wget "https://github.com/llvm/llvm-project/archive/refs/heads/main.zip" -O llvm.zip
$ unzip llvm.zip
As usual, create a build directory and run cmake in the llvm directory.
$ mkdir /build
$ cd /build
$ cmake -G "Unix Makefiles" \
-DCMAKE_INSTALL_PREFIX=/usr/local/llvm \
-DCMAKE_BUILD_TYPE=Release \
-DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra" \
/llvm-project-main/llvm
Navigate downwards in the generated files and only build clang-tidy.
$ cd /build/tools/clang/tools/extra/clang-tidy
$ make install
Cmake will install to /usr/local/llvm. Also, if you want to check out a specific version, use tags in the first step like this:
$ wget "https://github.com/llvm/llvm-project/archive/refs/tags/llvmorg-14.0.0.zip"
Note that you need to supply the matching builtin headers for running clang-tidy, which are located in GitHub under llvm-project/clang/lib/Headers and can by pointed to with -extra-arg=-I/path/to/builtin/headers.
I'm trying to build flatbuffers on OSX but I'm not sure how to proceed exactly. According to the doc. I should run cmake -G "Xcode". I did that and got the result:
-- The C compiler identification is Clang 5.1.0
-- The CXX compiler identification is Clang 5.1.0
-- Check for working C compiler using: Xcode
-- Check for working C compiler using: Xcode -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Check for working CXX compiler using: Xcode
-- Check for working CXX compiler using: Xcode -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Configuring done
-- Generating done
-- Build files have been written to: Temp/flatbuffers
However from there I'm not sure what to do. I've tried to run make but got the error message make: *** No targets specified and no makefile found. Stop.. Any idea how to build it?
When you ran cmake, you generated a project for the Xcode IDE (downloadable from the Apple app store).
If you want to build using make, use this command instead:
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release
After that,
make
should work as intended.
Instead make, just run following command in the shell:
$ cmakexbuild
After it finish you will get flatc in ./Debug folder.
On OSX it's recommended to use Homebrew to install the flatbuffer schema compiler.
brew install flatbuffers
Usage: Using the schema compiler
For Mac-OSX
Make sure Xcode is already installed in your machine. If not, install it by executing command xcode-select --install.
If you need latest changes download source code from repo or to get source code for a particular version download source from here
cd flatbuffers and execute cmake -G "Xcode" -DCMAKE_BUILD_TYPE=Release
If you encounter error like
CMake Warning:
No source or binary directory provided. Both will be assumed to be the
same as the current working directory, but note that this warning will
become a fatal error in future CMake releases.
-- The C compiler identification is unknown
-- The CXX compiler identification is unknown

Inside the log file CMakeError.log:

then refer this SO thread
success message is :

./FlatBuffers.xcodeproj or open project in xcode
Build and Run project from Xcode UI
cd Debugand you can see all the binaries present.
If you want flatc to be available globally:
ln -sf <path>/flatbuffers-1.12.0/Debug/flatc /usr/local/bin/flatc
Tried and Tested on
MacOSX: Mojave, version: 10.14.3, 10.14.6
Xcode: Version: 10.2.1(10E1001), 11.1(11A1027)
Note: Make sure you use the same version in a project for compatibility.
If you are not sure which version to pick, then you can clone the repo and go to a specific commit and build.
For e.g. For version 1.11, Commit version is bf9eb67a.
Follow the below steps to compile the flatbuffer code
Clone the Flatbuffer repo using - git clone https://github.com/google/flatbuffers.git
cd flatbuffers
cmake -G "Unix Makefiles"
make
FlatBuffers for LINUX(Ubuntu 16) install and build:
cd root project folder
yarn add flatc
cd node_modules of project
rm flatbuffers folder(if exist)
git clone https://github.com/google/flatbuffers.git
cd flatbuffers
cmake -G "Unix Makefiles" (install cmake if need)
make
cd root project folder
change path in command in package.json file from "./flatc" to "./node_modules/flatbuffers/flatc"
