A meson module to convenienty check for features.
Meson already provides means to check for features through compiler objects, but I've found myself still writing a lot of boilerplate code for what pretty much amounts to "setup-thing, check-thing, set-config".
meson-check addresses this through convention over configuration, by wrapping
all of that boilerplate up into convenient functions.
For the moment, the module is very C-centric, with existing (but limited) C++ support. Patches are welcome.
pip install meson-check
config = configuration_data()
check = import('check')
# Optionally, set some things up
check.setup(args: '-D_GNU_SOURCE', config: config)
# Check for a symbol in the standard library
check.symbol('clock_gettime')
# Check for a symbol in select libraries
check.symbol('shm_open', libraries: ['c', 'rt'])
# Check for a header declaration
check.declaration('unistd.h', 'environ')
# Check for a specific prototype declaration
check.declaration('sys/mman.h', 'int mincore(void *, size_t, unsigned char *)')
# Check for a header file
check.header('link.h')All functions return a boolean representing whether the check was successful or not.
