c - zlib and gdi32 with OpenSSL? -

this follow question undefined reference rsa_generate_key in openssl? have openssl program generate rsa key, follows : #include <stdio.h> #include <openssl/rsa.h> #include <openssl/pem.h> int main(int argc, char* argv[]) { rsa *r = null; int ret; r = rsa_new(); bignum *bne = null; ret = rsa_generate_key_ex(r, 2048, bne, null); return 0; } when compile gcc -i../include rsatest.c -lcrypto -l. i undefined reference errors functions in libraries gdi32 , zlib. so correct this, have add -lz , -lgdi32, as gcc -i../include/ rsatest.c -lcrypto -lz -lgdi32 -l. my question is, aren't static libcrypto , libssl self sufficient? in why having add libraries make work? there option should have added while compiling library prevent this? i'm using 64 bit windows mingw compiler. made openssl library of msys , make.

Formatting string according to pattern without regex in php -

how can format arbitrary string according flexible pattern? solution came using regular expressions, need 2 "patterns" (one search , 1 output). example: $str = '123abc5678"; desired output: 12.3ab-c5-67.8 i use pattern in variable (one user can define without knowledge of regular expressions) this: $pattern = '%%.%%%-%%-%%.%'; so user have use 2 different characters (% , .) a solution regex this: $str = '123abc5678'; $pattern_src = '@(.{2})(.{3})(.{2})(.{2})(.{1})@'; $pattern_rpl = "$1.$2-$3-$4.$5"; $res = preg_replace($pattern_src, $pattern_rpl, $str); //$res eq 12.3ab-c5-67.8 way complicated since user need define $pattern_src , $pattern_rpl. if string vary in length, more complex explain. yes, write function/parser builds required regular expressions based on simple user pattern %%.%%%-%%-%%.%. wonder if there "built in" way achieve php? thinking sprintf etc., doesn't seem trick. ideas? ...
