From 6286793e32535b2db1bc82398257a953ee36936f Mon Sep 17 00:00:00 2001 From: rcritten <> Date: Wed, 4 Jan 2006 22:07:58 +0000 Subject: Changes to allow the mod_nss to work in Apache 2.2.0. Based on a patch from Oden Eriksson. The conditional to determine which API to use is a bit weak at the moment but it works with Apache 2.0.54 and 2.2.0. --- Makefile.am | 4 +- Makefile.in | 6 +- configure | 7 +- configure.in | 4 +- mod_nss.c | 8 +- mod_nss.h | 9 + nss_engine_pphrase.c | 10 +- nss_engine_vars.c | 4 + nss_expr_eval.c | 8 +- nss_expr_parse.c | 1867 ++++++++++++++++++++++++++++++-------------------- nss_expr_parse.h | 111 ++- nss_expr_parse.y | 8 +- nss_expr_scan.c | 3 +- 13 files changed, 1252 insertions(+), 797 deletions(-) diff --git a/Makefile.am b/Makefile.am index 06486dc..61500fc 100644 --- a/Makefile.am +++ b/Makefile.am @@ -7,11 +7,13 @@ nss_pcache_SOURCES = nss_pcache.c ## Define the source file for the module libmodnss_la_SOURCES = mod_nss.c nss_engine_config.c nss_engine_init.c nss_engine_io.c nss_engine_kernel.c nss_engine_log.c nss_engine_pphrase.c nss_engine_vars.c nss_expr.c nss_expr_eval.c nss_expr_parse.y nss_expr_scan.l nss_util.c nss_engine_rand.c +libmodnss_la_LDFLAGS = -module -avoid-version ## Set the includes and libraries needed INCLUDES = -I@apache_inc@ @nspr_inc@ @nss_inc@ @apr_inc@ LIBS = @nspr_lib@ @nss_lib@ -lssl3 -lsmime3 -lnss3 -lsoftokn3 -lplc4 -lplds4 -lnspr4 @SSL2_TRUE@AM_CFLAGS=-DWANT_SSL2 +EXTRA_CPPFLAGS=@extra_cppflags@ install-libLTLIBRARIES: libmodnss.la @APXS@ -i -a -n nss libmodnss.la @@ -65,7 +67,7 @@ nss_expr_parse.c nss_expr_parse.h: nss_expr_parse.y LTCOMPILE = $(LIBTOOL) --mode=compile $(CC) $(DEFS) \ $(DEFAULT_INCLUDES) $(INCLUDES) $(AM_CPPFLAGS) $(CPPFLAGS) \ -
