Autotools: rework to simplify and fix recent issues (#674)
Completely rework the autotools build system, issues have cropped up due to the complexity and could cause issues on even semi-modern Linux systems (Ubuntu 20.04 for example). Changes include: Remove all curl/xc/cares m4 helper files, they go overboard on detections of functions and datatypes. Go back to more plain autoconf macros as they've come a long way over the years. Use known systems and heuristics to determine datatypes for functions like send() and recv(), rather than the error prone detection which required thousands of permutations and might still get it wrong. Remove unneeded configure arguments like --enable-debug or --enable-optimize, its more common for people to simply pass their own CFLAGS on the command line. Only require CARES_STATICLIB definition on Windows static builds, its not necessary ever for other systems, even when hiding non-public symbols. Remove some function and definition detections that were never used in c-ares The test framework is now embedded into the toplevel configure system, there was no need to chain build the test system as it is never built externally to c-ares. As a side-effect of the changes, a configure run completes in about 25% of the original time. This has been tested on various Linux distributions (of varying age), FreeBSD, MacOS, Windows (via MSYS2 with Mingw), and Solaris10/11 (by @dfandrich), AIX 7.3 (by @dfandrich). It is not unlikely that this may have broken more esoteric or legacy systems, and we'll likely need to be ready to accept bug reports and patches, but it has removed over 10k lines of build system code. It is very likely any issues that crop up will add far fewer lines of code to fix such systems. Fixes Bug: #670 Fix By: Brad House (@bradh352)pull/676/head

# |
||||
# DESCRIPTION |
||||
# |
||||
# For every FLAG1, FLAG2 it is checked whether the linker works with the |
||||
# flag. If it does, the flag is added FLAGS-VARIABLE |
||||
# |
||||
# If FLAGS-VARIABLE is not specified, the linker's flags (LDFLAGS) is |
||||
# used. During the check the flag is always added to the linker's flags. |
||||
# |
||||
# If EXTRA-FLAGS is defined, it is added to the linker's default flags |
||||
# when the check is done. The check is thus made with the flags: "LDFLAGS |
||||
# EXTRA-FLAGS FLAG". This can for example be used to force the linker to |
||||
# issue an error when a bad flag is given. |
||||
# |
||||
# INPUT gives an alternative input source to AC_COMPILE_IFELSE. |
||||
# |
||||
# NOTE: This macro depends on the AX_APPEND_FLAG and AX_CHECK_LINK_FLAG. |
||||
# Please keep this macro in sync with AX_APPEND_COMPILE_FLAGS. |

# AX_COMPILER_VENDOR |
||||
# |
||||
# DESCRIPTION |
||||
# |
||||
# Determine the vendor of the C, C++ or Fortran compiler. The vendor is |
||||
# returned in the cache variable $ax_cv_c_compiler_vendor for C, |
||||
# $ax_cv_cxx_compiler_vendor for C++ or $ax_cv_fc_compiler_vendor for |
||||
# (modern) Fortran. The value is one of "intel", "ibm", "pathscale", |
||||
# "clang" (LLVM), "cray", "fujitsu", "sdcc", "sx", "nvhpc" (NVIDIA HPC |
||||
# Compiler), "portland" (PGI), "gnu" (GCC), "sun" (Oracle Developer |
||||
# Studio), "hp", "dec", "borland", "comeau", "kai", "lcc", "sgi", |
||||
# "microsoft", "metrowerks", "watcom", "tcc" (Tiny CC) or "unknown" (if |
||||
# the compiler cannot be determined). |
||||
# |
||||
# To check for a Fortran compiler, you must first call AC_FC_PP_SRCEXT |
||||
# with an appropriate preprocessor-enabled extension. For example: |
||||
# |

# AC_LANG_PUSH([Fortran]) |

dnl ------------------------------------------------- |

dnl Public macro. |
||||
dnl |
||||
dnl This macro embeds shell code into configure script |
||||
dnl that amends, at configure runtime, the distclean |
||||
dnl and maintainer-clean targets of Makefiles located |
||||
dnl in all subdirs given in the mandatory white-space |
||||
dnl separated list argument. |
||||
dnl |
||||
dnl Embedding only takes place when using automake 1.14 |
||||
dnl or newer, otherwise amending code is not included |
||||
dnl in generated configure script. |
||||
dnl |
||||
dnl distclean and maintainer-clean targets are modified |
||||
dnl to avoid unconditional removal of dependency subdirs |
||||
dnl which triggers distclean and maintainer-clean errors |
||||
dnl when using automake 'subdir-objects' option along |
||||
dnl with per-target objects and source files existing in |
||||
dnl multiple subdirs used for different build targets. |
||||
dnl |
||||
dnl New behavior first removes each dependency tracking |
||||
dnl file independently, and only removes each dependency |
||||
dnl subdir when it finds out that it no longer holds any |
||||
dnl dependency tracking file. |
||||
dnl |
||||
dnl When configure option --disable-dependency-tracking |
||||
dnl is used no amending takes place given that there are |
||||
dnl no dependency tracking files. |

dnl |

dnl These basic checks are intended to be placed and |

dnl executed as early as possible in the resulting |

dnl ------------------------------------------------- |
||||
dnl Public macro. |
||||
dnl |
||||
dnl Usage of this macro ensures that generated configure |
||||
dnl script uses the same PATH_SEPARATOR check irrespective |
||||
dnl of autoconf or libtool version being used to generate |
||||
dnl configure script. |
||||
dnl |
||||
dnl Emits shell code that computes the path separator |
||||
dnl and stores the result in 'PATH_SEPARATOR', unless |
||||
dnl the user has already set it with a non-empty value. |
||||
dnl |
||||
dnl This path separator is the symbol used to separate |
||||
dnl or diferentiate paths inside the 'PATH' environment |
||||
dnl variable. |
||||
dnl |
||||
dnl Non-empty user provided 'PATH_SEPARATOR' always |
||||
dnl overrides the auto-detected one. |
||||
dnl |
||||
dnl Strictly speaking the check is done in two steps. The |
||||
dnl first, which does the actual check, takes place in |
||||
dnl XC_CONFIGURE_PREAMBLE macro and happens very early in |
||||
dnl generated configure script. The second one shows and |
||||
dnl logs the result of the check into config.log at a later |
||||
dnl configure stage. Placement of this second stage in |
||||
dnl generated configure script will be done where first |
||||
dnl direct or indirect usage of this macro happens. |
