PHP 4.0 Bug #9360: Type of the parameter conflicts with previous declaration of function

From: amra@us.ibm.com Operating system: OS400 PHP version: 4.0.4pl1 PHP Bug Type: Compile Failure Bug description: Type of the parameter conflicts with previous declaration of function When compiling using a C compiler, it does not allow parameters that are defined as const to be passed to a function that does not have the const qualifier in the prototype. Also, there are some parameter mismatches. Details below. ---------- begin [main/network.c] ---------- ERROR :129 Type of the parameter conflicts with previous declaration of function . INFORMATIONAL :129 Prototype has type pointer to unsigned character . INFORMATIONAL :129 Argument has type pointer to constant unsigned character . ---------- end [network.qwobj] ---------- Line 129: host_info = gethostbyname(host); But host is const char *. So I had to change line to as follows: host_info = gethostbyname((char *)host); ---------- begin [fsock.qwobj] ---------- ERROR :110 Type of the parameter conflicts with previous declaration of function . INFORMATIONAL :110 Prototype has type pointer to unsigned character . INFORMATIONAL :110 Argument has type pointer to constant unsigned character . ERROR :183 Type of the parameter conflicts with previous declaration of function . INFORMATIONAL :183 Prototype has type pointer to unsigned character . INFORMATIONAL :183 Argument has type pointer to signed integer . ERROR :183 Type of the parameter conflicts with previous declaration of function . INFORMATIONAL :183 Prototype has type pointer to signed integer . INFORMATIONAL :183 Argument has type pointer to unsigned integer . ---------- end [fsock.qwobj] ---------- Line 110: host_info = gethostbyname((char *)addr); But addr is const char *. So I had to change line to as follows: host_info = gethostbyname((char *)addr); Line 183: Protoype for getsockopt is: getsockopt(int, int, int, char *, int *). However, Line 183 contains: if (getsockopt(sockfd, SOL_SOCKET, SO_ERROR, &error, &len) < 0) { where error is int and len is socklen_t. I had to change line to as follows: if (getsockopt(sockfd, SOL_SOCKET, SO_ERROR, (char *)&error, (int *)&len) < 0) { I hope that these types of changes are made, so as to compile easily on any platform. -- Edit Bug report at: http://bugs.php.net/?id=9360&edit=1
