Hi all, I've a problem with random number generator. Let us consider the following code fragment: long int s = 123456; mt19937 rnd_gen(s); When I try to compile it I get the following error message: /home/mpalesi/WORK/TOOLS/BGL/current/boost/random/mersenne_twister.hpp: In member function `void boost::random::mersenne_twister<UIntType, w, n, m, r, a, u, s, b, t, c, l, val>::seed(Generator&) [with Generator = long int, UIntType = uint32_t, int w = 32, int n = 624, int m = 397, int r = 31, UIntType a = 09908b0df, int u = 11, int s = 7, UIntType b = 09d2c5680, int t = 15, UIntType c = 0efc60000, int l = 18, UIntType val = 0c77666de]': /home/mpalesi/WORK/TOOLS/BGL/current/boost/random/mersenne_twister.hpp:67: instantiated from `boost::random::mersenne_twister<UIntType, w, n, m, r, a, u, s, b, t, c, l, val>::mersenne_twister(Generator&) [with Generator = long int, UIntType = uint32_t, int w = 32, int n = 624, int m = 397, int r = 31, UIntType a = 09908b0df, int u = 11, int s = 7, UIntType b = 09d2c5680, int t = 15, UIntType c = 0efc60000, int l = 18, UIntType val = 0c77666de]' src/apsra_mesh.cpp:253: instantiated from here /home/mpalesi/WORK/TOOLS/BGL/current/boost/random/mersenne_twister.hpp:103: error: ` gen' cannot be used as a function make: *** [obj/apsra_mesh.o] Error 1 The src/apsra_mesh.cpp:253 is the row "mt19937 rnd_gen(s);" I've no problem if I try to compile: mt19937 rnd_gen(123456); Please, could you help me to resolve this problem?
