Check the version of Boost libraries
Boost does not provide any pkg-config files so to check the version of the Boost libraries, we need to use the means that the library itself provides.
def CheckBoost(context, version):
# Boost versions are in format major.minor.subminor
v_arr = version.split(".")
version_n = 0
if len(v_arr) > 0:
version_n += int(v_arr[0])*100000
if len(v_arr) > 1:
version_n += int(v_arr[1])*100
if len(v_arr) > 2:
version_n += int(v_arr[2])
context.Message('Checking for Boost version >= %s... ' % (version))
ret = context.TryRun("""
#include <boost/version.hpp>
int main()
{
return BOOST_VERSION >= %d ? 0 : 1;
}
""" % version_n, '.cpp')[0]
context.Result(ret)
return ret
conf = Configure(env, custom_tests = { 'CheckBoost' : CheckBoost })
if not (conf.CheckBoost('1.33')):
print 'Boost version >= 1.33 needed'
TryRun is not good for cross-compiling. Fortunately the BOOST_VERSION is a preprocessor define, so it should be enough to TryCompile. Replace the call to TryRun above with:
ret = context.TryCompile("""
#include <boost/version.hpp>
#if BOOST_VERSION < %d
#error Installed boost is too old!
#endif
int main()
{
return 0;
}
""" % version_n, '.cpp')
(I didn't test it, so there might be typo in this code. Please fix this page if you actually try it. Fixed. TryCompile returns an int. Removed tuple subscript [0])
