You might want to use the Anaconda compilers outside of conda-build On macOS and are modifying a different recipe, you should end up with anĪnaconda compilers implicitly add RPATH pointing to the conda environment ¶ You should end up with a super_duper_clang_osx-64 package. With any of your desired changes in place, go ahead and build the recipe. Remember that these have been modified by build.sh. The activate scripts that are being installed are where we actually set theĮnvironment variables. We define macos_machine in aggregate's conda_build_config.yaml: The symlink for Clang is a Clang implementation detail that sets the host The main material is in theįINAL_CPPFLAGS="-D_FORTIFY_SOURCE=2 -mmacosx-version-min=$".shĪctivate scripts are named according to our package name so they won't The Clang package recipe is in the clang folder. With that warning in mind, let's look at good ways to customize Clang. Remember that choosing the wrong flags can reduce security, reduce performance, We have also used them for all packages in Anaconda Distribution 5.0.0, exceptįor some minor customizations in a few recipes.
We have been careful to select good, general purpose, secure, and fast flags. You can then edit theĬonda_build_config.yaml file to specify your own packages. Packages by copying these recipes and changing the flags.
This design is intended to make it easy for you to customize your own compiler
INSTALL GFORTRAN IN CONDA ENVIRONMENT SOFTWARE
The compiler packages listed above are small packages that only include theĪctivation scripts and list most of the software they provide as runtime In particular, you'll need to copy the cross-linux.cmake file there, and reference it in your build.sh file: As anĮxample, please see our recipe for libnetcdf at In order to teach CMake about the sysroot, you must do additional work. We've filed issues at:Īdditionally, this Stack Overflow issue has some more information: Its own sysroot, CMake insists on ignoring that.
Even though the compiler itself understands Unfortunately, some software tools do not handle sysroots in intuitive ways.ĬMake is especially bad for this. Normal builds with Anaconda's compilers on Linux. Sysroot is said to be "cross-compiling." When the target OS and the build OSĪre the same, it is called a "pseudo-cross-compiler." This is the case for Any compilation that uses a sysroot other than the system System provides, and it is what establishes the libc compatibility bound for Ordinarily, the sysroot is something that your They include not only GCC, but also a "sysroot" with glibc, as well as the rest _sysconfigdata files by updating your Python package manually.Īnaconda's compilers for Linux are built with something called crosstool-ng.
INSTALL GFORTRAN IN CONDA ENVIRONMENT UPDATE
Other than conda-build while working with the new compilers, conda does notĪutomatically update Python, so make sure you have the correct Normally gets the latest from the default channel. Latest Python version available in the currently configured channels, which Conda-build automatically tries to use the The new _sysconfigdata customization system is only present in recent This variable is set at activation time using the activation hooks _PYTHON_SYSCONFIGDATA_NAME, which tells Python which _sysconfigdata file The compiler packages set the environment variable Itself is made with these Anaconda compilers. The Anaconda compilers as the default compilers. Python packages also include an alternative _sysconfigdata file that sets System, such as gcc and g++, as the default compilers. This file sets the compilers provided by the To enable this, the latest Python package builds haveĪ default _sysconfigdata file. Some users want to use the latest Anaconda packages but do not yet want to use You can activate the root environment with the command conda activate root. With the compiler packages in CONDA_PREFIX/etc/conda/activate.d, so no Conda-build does this activation for you using activation hooks installed Which you will use the compilers must first be activated so the scripts will We set these variables in conda activate.d scripts, so any environment in Many build tools such as make and CMake search by default for aĬompiler named simply gcc, so we set environment variables to point these Helping prevent the common mistake of using the wrong compiler. These fullĬompiler names are shown in the build logs, recording the host platform and You use will be something like x86_64-conda_cos6-linux-gnu-gcc. Package are "prefixed." Instead of gcc, the executable name of the compiler With (pseudo) cross-compiling in mind, all of the executables in a compiler The compiler packages can be installed with conda.
