Preparing a Mac machine for Bilder¶
NOTE: as of Catalina, installing in /opt is no longer an option, so we have moved to /usr/local
If all you need is python and sphinx (e.g., for builds of documentation), then you need only
- XCode with command line tools
- Latex installed as noted below
and then you can add the arguments, -W python, and your installed Python and CMake will be used if your path is correct.
Bilder on Darwin¶
Darwin comes with bash, so it is Bilder ready for the most part.
OS X Versions¶
Yosemite's XCode that supports C++ 11 by default.
El Capitan's clang compiler supports OpenMP.
Case insensitive file system¶
We have noted and filed bugs for CMake errors on OS X when using the case-sensitive file system. To fix we use the case-insensitive file system. There may be problems with various packages and the case-insensitive file system.
C and C++ compilers and Xcode command line tools¶
Install Xcode. To obtain version 11.3 (11.x is required for LLVM@12), visit https://developer.apple.com/xcode/download, then at the bottom third of the page, click on the "Additional Tools" link . Sign in with your Apple ID. Also download the Command Line Tools to match the version of Xcode that you are getting. The Xcode.app directory that is unpacked by opening the .xip file should be moved to the /Applications/ folder. The Command Line Tools is a DMG that has a PKG installer, so just run that. One must additionally execute this command before using any command line tools:
sudo xcodebuild -license
If you are upgrading from a previous installation you will want/need to run the following command
sudo xcode-select -s /Applications/Xcode.app
One can check the version of Xcode from the command-line with
xcodebuild -version
/usr/bin/clang --version
The clang should be version 11.0.0 with Xcode 11.3.1.
HomeBrew¶
One must select a non-OSX package manager for some additional packages. The candidates are HomeBrew, MacPorts, and Fink, with the HomeBrew being our recommendation at this time, as it is active, and it has the philosophy of not building extraneous stuff that is already present on OSX, which MacPorts tends to do, thus using up more disk space. HomeBrew also installs packages in their own subdirs with links to other places in $HOMEBREWDIR
with $HOMEBREWDIR being either /usr/local/homebrew
if on Intel Mac, or /opt/homebrew
if on Apple ARM architecture (M1, M2, etc.). Thus removal of a package a matter removing a directory and then removing broken links in $HOMEBREWDIR.
To install homebrew, go to https://brew.sh and follow the installation directions.
Get various packages...
brew install subversion gnupg libpng freetype gd ghostscript ninja wget imagemagick bison flex gperf libcapn pkg-config
git large file support (for VisIt)
brew install git-lfs
git lfs install --force --skip-smudge
Fortran comes with the homebrew gcc compiler.
brew install gcc # Intel architecture
On Apple ARM architecture gcc needs to be installed from source and there are some other packages to install
brew install --build-from-source gcc # ARM architecture
brew install qt@5 curl # ARM only. Qt is version 5.15.10 as of 7/3/2023
OPTIONAL:
If you receive an error regarding ruby version:
brew install ruby@2.3
may help.
LaTeX¶
Those with sufficient hard drive space (3.4GB after install) may wish to download the full MacTeX package from http://www.tug.org/mactex/downloading.html. After installing, one can see the 'README ME FIRST.pdf' in /Applications/Tex. You will likely need to add /usr/texbin to your path:
setenv PATH /usr/texbin:${PATH} # For tcsh
export PATH=/usr/texbin:${PATH} # For bash
For those who like GUIs, the !TeXworks in /Applications/TeX/TeXworks should work fine.
For those with limited space, install BasicTeX from https://tug.org/mactex/morepackages.html. Add to your PATH:
/usr/local/texlive/2017/bin/universal-darwin/
and then install the packages noted at
LaTeX packages needed by Bilder
You may need to use sudo.
sudo tlmgr update --self
sudo tlmgr install <needed packages>
and then used the autoupdate feature to get any additionally needed packages. This minimal installation is 230 M instead of the usual 2GB.
Disable spindump¶
for faster compilations via
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.spindump.plist
LLVM-Clang¶
LLVM-Clang (aka LlvmClang) is different from AppleClang. It has support for target attributes and openmp, and provides a build chain for high-performance computing. Check out the llvm-project of your chosen version.
We use homebrew to install this with
brew install llvm@15
As of Jul 2023, the default llvm version is 16, but it will not build Trilinos. LLVM-15 is the first version to have OpenMP support on the M1 chips. LLVM-12 is well tested for non-M1 Mac's.
Java¶
You will need to install java by invoking the executable in any way such as...
java -version
Follow the instructions in the dialog that takes you to the Oracle website and choose the latest version to download. (As of March 2021 this is 16.)
Chose the macOS installer from
https://www.oracle.com/java/technologies/javase-jdk16-downloads.html
HostName¶
For bilder to properly send emails the fully qualified hostname must set on the machine. To check this try...
hostname -f
this should return machinename.domainname.com rather than just machinename. If it does not, then set the hostname of the machine by typing the following commands.
sudo scutil --set ComputerName "machinename"
sudo scutil --set LocalHostName "machinename"
sudo scutil --set HostName "machinename.domainname.com"
dscacheutil -flushcache
Restart your Mac after this.
Power Saving Modes¶
For build machines that are not personal machines, disabling certain options will help in connectivity and responsiveness:
Under Spotlight
- disabled the main HD. (multiple mdworkers taking up a lot of cpu.)
Under Energy Saver
- Computer sleep: Set to never
- Unchecked Put hard disks to sleep when possible
- Unchecked Wake for network access
Python¶
For some older packages the "python" binary might be needed. Homebrew no longer supports installing Python2. Individual packages may expect "python" to be from Python2 or Python3, so it not clear if Python2 is needed to be installed or if one can link the python executable to the python3 one. One can install Python2, in any case from https://python.org/downloads.
X11¶
X11 should not be needed, but if it is needed:
Install XQuartz X11.
Create a symbolic link so that the X11 headers can be found by the compiler:
sudo ln -s /opt/X11/include/X11 /usr/local/include/X11
DEPRECATED INSTRUCTIONS¶
Other gfortran options (besides HomeBrew)¶
Option 2: HPC¶
Install gfortran from SourceForge HPC. (Do not also install the other gcc compilers.)
As of March 29, 2015, the version is 4.9.0.
Install via
$ tar xzf gfortran-4.9-bin.tar.gz -C /
Option 3: GNU¶
Install gfortran using the installer from http://gcc.gnu.org/wiki/GFortranBinaries.
As of March 29, 2015, the version is 4.9.0.
The binaries will end up being installed in /usr/local/bin
Git¶
If any repository package requires Git protocol, then for Lion and earlier you may need Git from http://git-scm.com/download/mac and add /usr/local/git/bin to your path.
Macports ###¶
This provides wget, freetype, and other utilities. Get macports from http://www.macports.org/install.php and install.
Note: Before proceeding with the installation of various macports packages noted below on Lion machines with Xcode 4.3, one needs to run
sudo xcode-select -switch /Applications/Xcode.app
Otherwise, there will be an error installing zlib during the wget installation below.
After the macports installation, do
sudo port install wget
sudo port install ImageMagick +no_x11
sudo port install f2c
XCode¶
Lion¶
On Lion, the command line compilers are not installed automatically. After installing Xcode, navigate to the
Preferences->Download dialog
and install the Command Line Tools. The dialog is..
!screenShotCommandLineTools.png!
or from the command line do
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer/
xcodebuild
(hit agree)
You may subsequently need to build your first package with sudo in order to accept the Xcode licenses.
Mountain Lion ###¶
Same as Mavericks?
Mavericks¶
sudo xcode-select --install
Java¶
(The below does not apply to yosemite.)
The cmake build may fail due to missing java headers linked to in /System/Library/Frameworks/JavaVM.framework/Headers. To fix:
cd /System/Library/Frameworks/JavaVM.framework/Headers
sudo mv jni.h jni.h.missing
