AC 21.5 This patch adds checks for headers to the existing TLS library checks. This should fix the first failure Vin reported recently. The second failure (missing openssl symbols at link time) needs a more extensive fix. diff -r d59bfb050ca8 ChangeLog --- a/ChangeLog Wed Oct 08 12:58:20 2014 -0600 +++ b/ChangeLog Thu Oct 09 15:43:06 2014 -0600 ＠＠ -1,3 +1,7 ＠＠ +2014-10-09 Jerry James <james(a)xemacs.org&gt; + + * configure.ac: Check for TLS headers as well as libraries. + 2014-10-07 Jerry James <james(a)xemacs.org&gt; * configure.ac: Add TLS support. diff -r d59bfb050ca8 configure.ac --- a/configure.ac Wed Oct 08 12:58:20 2014 -0600 +++ b/configure.ac Thu Oct 09 15:43:06 2014 -0600 ＠＠ -5332,20 +5332,35 ＠＠ fi dnl TLS support -if test "$with_tls" = "yes"; then - AC_CHECK_LIB(gnutls, gnutls_global_init, [with_tls=gnutls], - AC_CHECK_LIB(nss3, NSS_InitContext, [with_tls=nss], - AC_CHECK_LIB(ssl, SSL_library_init, [with_tls=openssl], [with_tls=no]))) -elif test "$with_tls" = "gnutls"; then - AC_CHECK_LIB(gnutls, gnutls_global_init, [with_tls=gnutls], +if test "$with_tls" = "gnutls"; then + AC_CHECK_HEADER([gnutls/gnutls.h], + [AC_CHECK_LIB(gnutls, gnutls_global_init, [with_tls=gnutls], + [XE_DIE("Required gnutls support cannot be provided.")])], [XE_DIE("Required gnutls support cannot be provided.")]) elif test "$with_tls" = "nss"; then - AC_CHECK_LIB(nss3, NSS_InitContext, [with_tls=nss], + AC_CHECK_HEADER([nss.h], + [AC_CHECK_LIB(nss3, NSS_InitContext, [with_tls=nss], + [XE_DIE("Required NSS support cannot be provided.")])], [XE_DIE("Required NSS support cannot be provided.")]) elif test "$with_tls" = "openssl"; then - AC_CHECK_LIB(ssl, SSL_library_init, [with_tls=openssl], + AC_CHECK_HEADER([openssl/ssl.h], + [AC_CHECK_LIB(ssl, SSL_library_init, [with_tls=openssl], + [XE_DIE("Required openssl support cannot be provided.")])], [XE_DIE("Required openssl support cannot be provided.")]) fi +dnl Autodetection +if test "$with_tls" = "yes"; then + AC_CHECK_HEADER([gnutls/gnutls.h], + [AC_CHECK_LIB(gnutls, gnutls_global_init, [with_tls=gnutls])]) +fi +if test "$with_tls" = "yes"; then + AC_CHECK_HEADER([nss.h], + [AC_CHECK_LIB(nss3, NSS_InitContext, [with_tls=nss])]) +fi +if test "$with_tls" = "yes"; then + AC_CHECK_HEADER([openssl/ssl.h], + [AC_CHECK_LIB(ssl, SSL_library_init, [with_tls=openssl], [with_tls=no])]) +fi if test "$with_tls" != "no"; then AC_DEFINE(WITH_TLS) if test "$with_tls" = "gnutls"; then I will push this patch momentarily. -- Jerry James http://www.jamezone.org/ _______________________________________________ XEmacs-Patches mailing list XEmacs-Patches(a)xemacs.org http://lists.xemacs.org/mailman/listinfo/xemacs-patches
