Configure Cmake

Description

Propagate R's configuration variables into the Cmake options, where possible.

Usage

configure(
  c.compiler = TRUE,
  c.flags = c.compiler,
  cxx.compiler = TRUE,
  cxx.flags = cxx.compiler,
  fortran.compiler = TRUE,
  fortran.flags = fortran.compiler,
  cpp.flags = c.compiler || cxx.compiler,
  pic.flags = TRUE,
  ld.flags = c("exe", "module", "shared"),
  make = TRUE,
  ar = TRUE,
  ranlib = TRUE,
  release.build = TRUE
)

formatArguments(options)

Arguments

c.compiler	Logical scalar indicating whether to propagate R's choice of C compiler.
c.flags	Logical scalar indicating whether to propagate R's choice of C flags.
cxx.compiler	Logical scalar indicating whether to propagate R's choice of C++ compiler.
cxx.flags	Logical scalar indicating whether to propagate R's choice of C++ flags.
fortran.compiler	Logical scalar indicating whether to propagate R's choice of Fortran compiler.
fortran.flags	Logical scalar indicating whether to propagate R's choice of Fortran flags.
cpp.flags	Logical scalar indicating whether to propagate R's choice of C/C++ preprocessing flags.
pic.flags	Logical scalar indicating whether to propagate R's choice of each language's position-independent flags. This also sets the CMAKE_POSITION_INDEPENDENT_CODE variable.
ld.flags	Logical scalar indicating whether to add R's choice of linker flags to the CMake variables for each target type.
make	Logical scalar indicating whether to propagate R's choice of make command.
ar	Logical scalar indicating whether to propagate R's choice of command to make static libraries.
ranlib	Logical scalar indicating whether to propagate R's choice of command to index static libraries.
release.build	Logical scalar indicating whether to configure Cmake for a release build. Note that this has no effect on Windows, where the release flags must be set during the build itself.
options	Character vector of optional arguments from configure.

Value

For configure, a named character vector containing the name and value of each option.

For formatArguments, a character vector with Cmake arguments on the command line. NA values are ignored, and values with spaces or empty strings are quoted.

Defaults for biocmake

Description

Defaults for biocmake

Usage

defaultCommand()

defaultDownloadVersion()

defaultMinimumVersion()

defaultCacheDirectory()

Details

The BIOCMAKE_CMAKE_COMMAND environment variable will override the default setting of defaultCommand.

The BIOCMAKE_CMAKE_DOWNLOAD_VERSION environment variable will override the default setting of defaultDownloadVersion.

The BIOCMAKE_CMAKE_MINIMUM_VERSION environment variable will override the default setting of defaultMinimumVersion.

The BIOCMAKE_CMAKE_CACHE_DIRECTORY environment variable will override the default setting of defaultCacheDirectory.

Value

For defaultCommand, a string specifying the expected command-line invocation of an existing Cmake installation.

For defaultDownloadVersion, a string specifying the version of Cmake to download if no existing installation can be found.

For defaultMinimumVersion, a string specifying the minimum version of an existing Cmake installation.

For defaultCacheDirectory, a string containing the path to the cache directory for biocmake-managed Cmake installations.

Download Cmake

Description

Download Cmake binaries for the current architecture. This uses dir.expiry to remove unused versions of the biocmake-managed Cmake.

Usage

download(
  download.version = defaultDownloadVersion(),
  cache.dir = defaultCacheDirectory(),
  ignore.cache = FALSE
)

Arguments

download.version	String specifying the Cmake version to download.
cache.dir	String specifying the location of the directory in which to cache Cmake installations.
ignore.cache	Logical scalar specifying whether to ignore any existing cached version of Cmake, in which case the binaries will be downloaded again.

Value

String containing the path to the Cmake executable.

Find Cmake

Description

Find an existing Cmake installation or, if none can be found, install a biocmake-managed Cmake instance.

Usage

find(
  command = defaultCommand(),
  minimum.version = defaultMinimumVersion(),
  can.download = TRUE,
  ...
)

Arguments

command	String containing the command to check for an existing installation.
minimum.version	String specifying the minimum acceptable version of an existing installation.
can.download	Logical scalar indicating whether to download Cmake if no acceptable existing installation can be found.
...	Further arguments to pass to download.

Details

If the BIOCMAKE_FIND_OVERRIDE environment variable is set to a command or path to a Cmake executable, it is returned directly and all other options are ignored.

On Windows, it is strongly recommended to download Rtools (see https://cran.r-project.org/bin/windows/Rtools/rtools44/rtools.html). This provides a pre-configured Cmake that is guaranteed to work.

Value

String containing the command to use to run Cmake.
