fc_config

Fortran configuration helpers

waflib.Tools.fc_config.fc_flags(conf)[source]

Configuration Method bound to waflib.Configure.ConfigurationContext

Defines common fortran configuration flags and file extensions

waflib.Tools.fc_config.fc_add_flags(conf)[source]

Configuration Method bound to waflib.Configure.ConfigurationContext

Adds FCFLAGS / LDFLAGS / LINKFLAGS from os.environ to conf.env

waflib.Tools.fc_config.check_fortran(self, *k, **kw)[source]

Configuration Method bound to waflib.Configure.ConfigurationContext

Compiles a Fortran program to ensure that the settings are correct

waflib.Tools.fc_config.check_fc(self, *k, **kw)[source]

Configuration Method bound to waflib.Configure.ConfigurationContext

Same as waflib.Tools.c_config.check() but defaults to the Fortran programming language (this overrides the C defaults in waflib.Tools.c_config.validate_c())

waflib.Tools.fc_config.fortran_modifier_darwin(conf)[source]

Configuration Method bound to waflib.Configure.ConfigurationContext

Defines Fortran flags and extensions for OSX systems

waflib.Tools.fc_config.fortran_modifier_win32(conf)[source]

Configuration Method bound to waflib.Configure.ConfigurationContext

Defines Fortran flags for Windows platforms

waflib.Tools.fc_config.fortran_modifier_cygwin(conf)[source]

Configuration Method bound to waflib.Configure.ConfigurationContext

Defines Fortran flags for use on cygwin

waflib.Tools.fc_config.check_fortran_dummy_main(self, *k, **kw)[source]

Configuration Method bound to waflib.Configure.ConfigurationContext

Determines if a main function is needed by compiling a code snippet with the C compiler and linking it with the Fortran compiler (useful on unix-like systems)

Configuration Method bound to waflib.Configure.ConfigurationContext Returns True if ‘useful’ link options can be found in txt

waflib.Tools.fc_config.check_fortran_verbose_flag(self, *k, **kw)[source]

Configuration Method bound to waflib.Configure.ConfigurationContext

Checks what kind of verbose (-v) flag works, then sets it to env.FC_VERBOSE_FLAG

waflib.Tools.fc_config._match_ignore(line)[source]

Returns True if the line should be ignored (Fortran verbose flag test)

Given the output of verbose link of Fortran compiler, this returns a list of flags necessary for linking using the standard linker.

private

waflib.Tools.fc_config.check_fortran_clib(self, autoadd=True, *k, **kw)[source]

Configuration Method bound to waflib.Configure.ConfigurationContext

Obtains the flags for linking with the C library if this check works, add uselib=’CLIB’ to your task generators

waflib.Tools.fc_config.getoutput(conf, cmd, stdin=False)[source]

Obtains Fortran command outputs

Task generator method

The configuration test declares a unique task generator, so we create other task generators from there for fortran link tests

Feature:link_main_routines_func
waflib.Tools.fc_config.mangling_schemes()[source]

Generate triplets for use with mangle_name (used in check_fortran_mangling) the order is tuned for gfortan

waflib.Tools.fc_config.mangle_name(u, du, c, name)[source]

Mangle a name from a triplet (used in check_fortran_mangling)

waflib.Tools.fc_config.check_fortran_mangling(self, *k, **kw)[source]

Configuration Method bound to waflib.Configure.ConfigurationContext

Detect the mangling scheme, sets FORTRAN_MANGLING to the triplet found

This test will compile a fortran static library, then link a c app against it

waflib.Tools.fc_config.set_lib_pat(self)[source]

Task generator method

Sets the Fortran flags for linking with Python
feature:pyext
waflib.Tools.fc_config.detect_openmp(self)[source]

Configuration Method bound to waflib.Configure.ConfigurationContext

Detects openmp flags and sets the OPENMP FCFLAGS/LINKFLAGS

waflib.Tools.fc_config.check_gfortran_o_space(self)[source]

Configuration Method bound to waflib.Configure.ConfigurationContext

waflib.Tools.fc_config.conf(f)

Decorator: attach new configuration functions to waflib.Build.BuildContext and waflib.Configure.ConfigurationContext. The methods bound will accept a parameter named ‘mandatory’ to disable the configuration errors:

def configure(conf):
        conf.find_program('abc', mandatory=False)
Parameters:f (function) – method to bind
waflib.Tools.fc_config.feature(*k)

Decorator that registers a task generator method that will be executed when the object attribute feature contains the corresponding key(s):

from waflib.Task import feature
@feature('myfeature')
def myfunction(self):
        print('that is my feature!')
def build(bld):
        bld(features='myfeature')
Parameters:k (list of string) – feature names
waflib.Tools.fc_config.before_method(*k)[source]

Decorator that registera task generator method which will be executed before the functions of given name(s):

from waflib.TaskGen import feature, before
@feature('myfeature')
@before_method('fun2')
def fun1(self):
        print('feature 1!')
@feature('myfeature')
def fun2(self):
        print('feature 2!')
def build(bld):
        bld(features='myfeature')
Parameters:k (list of string) – method names
