hi I was trying to compile a simulation code on multiple platforms. It involves a thread-safe 48bit POSIX random number generator (RNG), drand48_r/seed48_r. I tried gcc 4.4 on Ubuntu 10.4 and it compiled fine. However, when I run gcc 4.0 on Mac OS X, it gave me error: posix_randr.h:29: error: array type has incomplete element type and the offending lines read like: typedef struct drand48_data RandType; __device__ float rand_uniform01(RandType t[RAND_BUF_LEN]); ... Similar error when compiling on Windows with MinGW gcc 3.4. Because drand48 is supposed to be a POSIX function, I am a bit surprised when seeing multiple platforms responded differently. Did I miss anything? or this is the correct behavior? thanks Qianqian
