| − | This page has simplified steps for building '''''quickly'''''. See [https://github.com/BRL-CAD/brlcad/blob/main/INSTALL INSTALL] for more detailed instruction. | + | BRL-CAD source files contain an [http://brlcad.svn.sourceforge.net/viewvc/brlcad/brlcad/trunk/INSTALL INSTALL] file with general instructions. This page contains simplified tips for building '''''quickly'''''. |
| | | | |
| | + | == Obtain Dev Tools == |
| | | | |
| − | == Step 1: Install Dev Tools ==
| + | If you downloaded the virtual machine disk image, YOU DON'T NEED TO INSTALL ANYTHING ELSE. Skip this step. |
| | | | |
| − | To build, you want the latest [https://cmake.org/download/ CMake], a recent compiler, and at least 3GB of disk space. You will also want [https://git-scm.com/downloads/guis Git] to obtain the latest source code.
| + | BRL-CAD uses the CMake build system and will compile with most compilers, so first up is to [http://www.cmake.org/cmake/resources/software.html download and install it]. If needed, compiling from their source distribution is actually very easy. |
| | | | |
| − | * Minimum versions:
| + | If you're on some other Debian/Ubuntu system, you can install pretty much everything you might want with aptitude: |
| − | ** CMake must be 3.18 or later
| |
| − | ** Git must be 2.17 or later
| |
| − | ** Compiler must be C++11-compliant
| |
| − | *** If using Visual Studio, version 2015 (14.0+) or later
| |
| − | *** If using GCC/G++, version 4.8.1 or later
| |
| − | *** If using LLVM/Clang 3.3 or later
| |
| − | *** If using Intel, version 2015 (15.0+) or later
| |
| | | | |
| | + | <pre> |
| | + | aptitude install build-essential make cmake |
| | + | aptitude install sed byacc flex xsltproc |
| | + | aptitude install libncursesw5-dev libfontconfig-dev |
| | + | aptitude install xserver-xorg-dev |
| | + | aptitude install libx11-dev libxi-dev libxt-dev libxau-dev libxext-dev libxmu-dev libxmu-headers |
| | + | aptitude install libtnt-dev libpng12-dev zlib1g-dev libsm-dev tcl8.5-dev tk8.5-dev itcl3-dev |
| | + | </pre> |
| | | | |
| − | * '''Windows''': Install [https://gitforwindows.org Git], [https://cmake.org/download/ CMake], and [https://visualstudio.microsoft.com/vs/community/ Visual Studio Community] or Professional. VS Code should also work, but you will need to install the "[https://visualstudio.microsoft.com/downloads/ Build Tools for Visual Studio]" also.
| + | If you're on a Mac or Windows, you just need to install CMake and developer tools. |
| | | | |
| | + | == Download BRL-CAD == |
| | | | |
| − | * '''Mac''': Install [https://cmake.org/download/ CMake] and XCode or run this in Terminal: <pre>xcode-select --install</pre>
| + | Release sources may be obtained from [https://sourceforge.net/projects/brlcad/files/BRL-CAD%20Source/ Sourceforge] or directory from Subversion: |
| | | | |
| | + | If you downloaded the virtual machine disk image, WE ALREADY DID THIS FOR YOU. See the brlcad.svn directory. |
| | | | |
| − | * '''Linux''' and Windows Subsystem for Linux ('''WSL'''):
| + | <pre> |
| | + | svn checkout https://brlcad.svn.sourceforge.net/svnroot/brlcad/brlcad/trunk brlcad |
| | + | cd brlcad |
| | + | </pre> |
| | | | |
| − | Installing is easiest with a package management system like apt, brew, yum, and dnf that install for you. Alas, the tools and names change frequently, so the following are platform-specific recommendations that may need to be adjusted for your system.
| + | == Configure == |
| | | | |
| − | ** WSL: You should be good to go.
| + | Next, we set up a build directory and configure our compilation. BRL-CAD adhere's to a high conformance standard and considers most warnings as errors, so we turn off that strict behavior just so the build doesn't halt on trivialities. |
| | | | |
| − | ** Debian/Ubuntu: <pre>apt install build-essential make cmake</pre>
| + | We could add -DCMAKE_BUILD_TYPE=Release to get an optimized build or -DCMAKE_BUILD_TYPE=Debug to get one better suited for development work. |
| | | | |
| − | If you're on an older distribution, you may need to manually install a more recent version of cmake.
| + | <pre> |
| | + | mkdir .build |
| | + | cd .build |
| | + | cmake .. -DBRLCAD_ENABLE_STRICT=OFF |
| | + | </pre> |
| | | | |
| − | ** Fedora: <pre>yum install clang++ make cmake</pre>
| + | == Compile == |
| | | | |
| − | ** CentOS: <pre>yum install python3-pip devtoolset-9</pre><pre>pip3 install cmake</pre><pre>scl enable devtoolset-9 bash</pre>
| + | Compilation will usually take anywhere from a couple minutes to an hour depending on your hardware. If you had a quad-core CPU, you might run '"make -j4" to request compiling in parallel. |
| | | | |
| | + | <pre> |
| | + | make |
| | + | make test |
| | + | </pre> |
| | | | |
| − | * BSD: we assume you know what you're doing and can follow the gist
| + | We run make test to see if all went well. If the build fails, it can be helpful to run make again capturing output to a log file. E.g., make > build.log 2>&1 |
| | | | |
| − | == Step 2: Install Dependencies == | + | == Install == |
| | | | |
| − | * '''Windows''': You can skip this step.
| + | Depending on the version of sources you start with, BRL-CAD should install into /usr/brlcad/SUBDIR where SUBDIR is rel-VERSION or dev-VERSION. |
| | | | |
| − | * '''Mac''': Install the latest [https://www.xquartz.org XQuartz]
| + | <pre> |
| − | | + | sudo make install |
| − | * '''Linux''': BRL-CAD needs the Xorg development packages
| + | ls -la /usr/brlcad |
| − | | + | /usr/brlcad/*/bin/mged |
| − | ** Debian/Ubuntu: <pre>apt install libc6-dev libfreetype-dev libfontconfig-dev</pre><pre>apt install xserver-xorg-dev libx11-dev libxi-dev libglu1-mesa-dev</pre>
| + | </pre> |
| − | | |
| − | ** Fedora: <pre>yum install freetype-devel fontconfig-devel</pre><pre>yum install libX11-devel libXext-devel libXi-devel mesa-libGL-devel</pre>
| |
| − | | |
| − | == Step 3: Download BRL-CAD ==
| |
| − | | |
| − | We recommend obtaining BRL-CAD by forking or cloning our repository on [https://github.com/BRL-CAD/brlcad GitHub].
| |
| − | | |
| − | * '''Windows''': If you're going to build with Visual Studio, run Git GUI specifying this repository to clone: <pre>https://github.com/BRL-CAD/brlcad.git</pre>. If you're building under WSL, clone from the git-bash command line.
| |
| − | | |
| − | * '''Mac''': You can either run the Git GUI, or you can run this in Terminal: <pre>git clone https://github.com/BRL-CAD/brlcad.git</pre>
| |
| − | | |
| − | * '''Linux''' and '''WSL''': <pre>git clone https://github.com/BRL-CAD/brlcad.git</pre>
| |
| − | | |
| − | The "brlcad" folder created after cloning is a full source checkout of BRL-CAD and contains a README with additional info. If you run into trouble cloning from git, snapshot source releases [https://sourceforge.net/projects/brlcad/files/BRL-CAD%20Source/ are available].
| |
| − | | |
| − | | |
| − | == Step 4: Create a Build directory ==
| |
| − | | |
| − | You can create a build folder anywhere, but it's typically named "build" and is in or near your "brlcad" source directory.
| |
| − | | |
| − | * '''Windows''': create a folder named "build" inside your "brlcad" folder
| |
| − | | |
| − | * '''Mac''', '''Linux''': <pre>mkdir -p brlcad/build</pre> | |
| − | | |
| − | | |
| − | == Step 5: Configure ==
| |
| − | | |
| − | It's first recommended during configure and compilation that you temporarily suspend any anti-virus software as they're notorious for issuing false-positives alerts and blocking necessary operations. Some BRL-CAD tools use temporary network ports that will need to be allowed as well, if prompted.
| |
| − | | |
| − | Next, you'll run CMake to configure and generate a build system.
| |
| − | | |
| − | CMake needs to know the top-level source dir (i.e., "brlcad" dir you cloned) and "build" dir you made are located. For your first time, we also recommend setting these CMake variables to avoid trivial issues:
| |
| − | BRLCAD_ENABLE_STRICT=OFF
| |
| − | BRLCAD_ENABLE_COMPILER_WARNINGS=OFF
| |
| − | BRLCAD_BUNDLED_LIBS=ON
| |
| − | | |
| − | * '''Windows''': you can use CMake GUI where you'll specify 1) your source dir (i.e. path to the "brlcad" folder that has README), 2) the build dir, and 3) variables. CMake does not display variables the first time you run, but you can "+ Add Entry" to add them or run "Configure" to list them. Once dirs and variables are set, run "Configure" again and finally "Generate" to create a Visual Studio build system. [[File:Running_cmake_on_windows.png|200px|thumb|right|Running CMake GUI on Windows]]
| |
| − | | |
| − | * '''Mac''': You can either run CMake GUI like described for Windows, specifying your source dir, build dir, and the above variables, or you can follow the steps below for Linux in Terminal.
| |
| − | | |
| − | * '''Linux''': <pre>cd brlcad/build</pre><pre>cmake .. -DBRLCAD_ENABLE_STRICT=NO -DBRLCAD_BUNDLED_LIBS=ON -DCMAKE_BUILD_TYPE=Release</pre>
| |
| − | | |
| − | See [https://github.com/BRL-CAD/brlcad/blob/main/INSTALL INSTALL] for more CMake options.
| |
| − | | |
| − | If CMake was successful, there will be a summary of the build printed at the end, it will say "Configured", and then "Generated" after a build system is finally done being written out for compiling BRL-CAD.
| |
| − | | |
| − | If CMake was unsuccessful, scan the output for any error messages indicating what is failing or missing as it's typically a missing tool, missing library, or erroneous setting.
| |
| − | | |
| − | == Step 6: Compile ==
| |
| − | | |
| − | '''Windows''': navigate to your build directory and open the BRLCAD.sln file with Visual Studio. You can ignore any warning about a duplicate "regress" target. Compile the default ALL_BUILD solution.
| |
| − | | |
| − | '''Mac''', '''Linux''': while still in the build directory from Step 4, run <pre>make</pre>. If you have multiple cores, you can alternatively compile in parallel specifying a desire number of cores, e.g., <pre>make -j10</pre>
| |
| − | | |
| − | If the build fails, re-run while capturing all output to a log: make 2>&1 | tee build.log
| |
| − | Please [https://github.com/BRL-CAD/brlcad/issues report] any build failures.
| |
| − | | |
| − | Note: Compilation can take anywhere from a couple minutes to an hour depending on hardware. If you had a quad-core CPU, you might run '"make -j4" to speed things up by compiling in parallel.
| |
| | | | |
| | + | == Quick test == |
| | | | |
| − | == Step 7: Run! ==
| + | You don't have to install, though, and can just run binaries that are in the brlcad/.build/bin directory. |
| − | | |
| − | You don't have to install to run BRL-CAD. You can run the binaries you just compiled as they are in the brlcad/build/bin directory. On Windows, they can be in Debug/ or Release/ folders. Of the hundreds of tools in BRL-CAD, here's just a few to get you started: | |
| | | | |
| | <pre> | | <pre> |
| − | bin/benchmark run | + | bin/benchmark |
| | bin/mged | | bin/mged |
| − | bin/archer
| |
| | </pre> | | </pre> |
| | | | |
| − | The first command (benchmark) will evaluate system performance and you can send results to benchmark at brlcad dot org.
| + | That's it! If you have a Release compile, you can submit your benchmark results to benchmark at brlcad dot org. Be sure to check out the extensive [[Documentation]] and [[Main_Page]] for tutorials and [[Contributor Quickies]] for ways to get involved! |
| − | | |
| − | The second command (mged) is BRL-CAD's main graphical user interface application.
| |
| − | | |
| − | The third command (archer) is BRL-CAD's newer graphical interface under development.
