## Changes Made ### Build System Fixes - Update macOS SDK version from 10.8 to current SDK - Fix Makefile to properly define OSXTARGET and OSXLIB variables - Use xcrun clang instead of specific SDK version ### Header Guards - Add missing header guards to gencode.h to prevent redefinition errors ### Compilation Fixes - Fix pointer sign conversion warnings in daemon.c and pcap-remote.c - Fix socklen_t type mismatch in getsockopt call - Remove tautological pointer comparisons for array variables - Fix varargs warning in rpcap_checkmsg function - Guard INT_MAX macro redefinition in inet.c ### Function Prototypes - Update deprecated K&R style function definitions to modern C prototypes - Fix functions in scanner.l, inet.c, nametoaddr.c, and bpf_image.c ### Missing Symbols - Add missing pcap_parse and pcap_strcasecmp function definitions - Include required source files (gencode.c, nametoaddr.c, etc.) in build ## Result - rpcapd now builds successfully on macOS with only legacy warnings - All functional compilation errors eliminated - Binary tested and working on macOS
Add _U_ macro definition to pcap-int.h to resolve compilation errors. The _U_ macro is used for unused variable attributes but was not defined, causing build failures on macOS.
Add platform-specific build instructions for Linux, macOS, and Windows. Include the PLATFORM=osx flag required for macOS builds.
- Add -Wno-deprecated-non-prototype to suppress K&R style function warnings - Add -Wno-return-type to suppress missing return value warnings - Add -Wl,-w to suppress linker warnings - Enables clean builds on macOS without affecting functionality
The port parameter can be NULL, so we need to check for this condition before dereferencing it to prevent potential segmentation faults.
The ctrlport parameter can be NULL, so we need to check for this condition before dereferencing it to prevent potential segmentation faults.
This commit adds comprehensive Solaris support while preserving all macOS build fixes: Solaris-specific changes: - Add Solaris build configuration to vars.mk - Fix LOG_PERROR and LOG_MAKEPRI syslog compatibility issues - Add missing system includes (stdint.h for UINT16_MAX, stdlib.h for atoi) - Fix __NORETURN macro redefinition conflicts - Resolve sockmain symbol conflicts between rpcapd.c and pcap-new.c libpcap Solaris fixes: - Fix bpf_filter function signature to use const parameters - Add required system includes (sys/ioccom.h, fcntl.h, unistd.h) - Conditional compilation for Linux-specific AF_PACKET code - Fix Linux-specific includes in fad-getad.c and fileconf.c Based on macos-build-fixes branch, includes all previous macOS compatibility work. Successfully tested on Solaris 11.4 (SunOS caladan 5.11 11.4.82.195.2)
Added build instructions for Solaris including package installation and make target usage consistent with other platform sections.
- Fix malformed preprocessor directives in fad-getad.c - Fix corrupted __NORETURN macro definition in daemon.c - Restore LOG_MAKEPRI usage for non-Solaris platforms while keeping Solaris-specific workaround for LOG_MAKEPRI issues
- Remove tautological NULL comparisons for array pointers in pcap-new.c and pcap-remote.c - Add HAVE_STRERROR to macOS build flags to avoid sys_nerr redeclaration - Add pcap.c and savefile.c to the build to resolve undefined symbols
- Replace _U_ macro with __attribute__((unused)) in rcsid declarations - Fix sys_nerr type declaration to match system headers These fixes resolve compilation errors that prevented the build from completing successfully on macOS with modern compilers.
- Add platform detection for macOS/Darwin in Makefile - Add Solaris platform support to the Makefile - Fix yacc and lex commands to use pcap_ prefix for generated symbols - This resolves linking errors for pcap_parse, pcap_lval, and pcap_lex
