From df3ca59116bff161c0fa44b1af7915dc8c1da20e Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Sat, 11 Dec 2004 18:47:22 +0000 Subject: Dan Fandrich: Here's a stab at a consolidation of the SSL detection heuristics into configure. Source files aren't changed by this patch, except for setup.h and the various config*.h files. Within the configure script, OPENSSL_ENABLED is used to determine if SSL is being used or not, and outside configure, USE_SSLEAY means the same thing; this could be even further unified some day. Now, when SSL is not detected, configure skips the various checks that are dependent on SSL, speeding up the configure process and avoiding complications with cross compiles. I also updated all the architecture- specific config files I could see, but I couldn't test them. --- configure.ac | 115 ++++++++++++++++++++-------------- curl-config.in | 8 +-- lib/Makefile.netware | 1 + lib/config-amigaos.h | 3 + lib/config-riscos.h | 3 - lib/config-vms.h | 7 ++- lib/config.dj | 1 + lib/setup.h | 17 ----- packages/vms/config-vms.h_with_ssl | 7 ++- packages/vms/config-vms.h_without_ssl | 7 ++- src/config-riscos.h | 5 +- 11 files changed, 93 insertions(+), 81 deletions(-) diff --git a/configure.ac b/configure.ac index b204653d9..d7f4c1f45 100644 --- a/configure.ac +++ b/configure.ac @@ -433,35 +433,6 @@ AC_HELP_STRING([--disable-nonblocking],[Disable non-blocking socket detection]), CURL_CHECK_NONBLOCKING_SOCKET ]) -dnl ********************************************************************** -dnl Check for the random seed preferences -dnl ********************************************************************** - -AC_ARG_WITH(egd-socket, -AC_HELP_STRING([--with-egd-socket=FILE], - [Entropy Gathering Daemon socket pathname]), - [ EGD_SOCKET="$withval" ] -) -if test -n "$EGD_SOCKET" ;
