Hi, I found a compile warning in APR, following is a C program that will report warning when compiled in my system:
~/Downloads/apr-1.6.5$ cat a.c #include <apr.h> #include <stdio.h> int main(void) { apr_off_t a = 0; printf("%" APR_OFF_T_FMT "\n", a); return(0); } ~/Downloads/apr-1.6.5$ gcc -I./include a.c a.c:7:33: warning: format specifies type 'long' but the argument has type 'apr_off_t' (aka 'long long') [-Wformat] printf("%" APR_OFF_T_FMT "\n", a); ~~~ ^ 1 warning generated. I checked apr.h and found it define APR_OFF_T_FMT as "ld" because macro DARWIN_10 is not defined.
