Hi,
could someone please give me a hint,
how to use libapreq from my Apache module?
I'm using Apache 1.3.29 on OpenBSD 3.9-beta,
with the p5-libapreq-1.3 package which includes these files:
/usr/local/libdata/perl5/site_perl/i386-openbsd/auto/libapreq/include/apache_cookie.h
/usr/local/libdata/perl5/site_perl/i386-openbsd/auto/libapreq/include/apache_multipart_buffer.h
/usr/local/libdata/perl5/site_perl/i386-openbsd/auto/libapreq/include/apache_request.h
/usr/local/libdata/perl5/site_perl/i386-openbsd/auto/libapreq/libapreq.a
My module contains 3 files (mod_pref.c, mod_pref.h and pgsql.c
in the subdir module/) and builds and works fine using these commands:
gcc -Wall -ggdb -O0 -O2 -pipe -DDEV_RANDOM=/dev/arandom
-DMOD_SSL=208116 -DEAPI -DUSE_SETUSERCONTEXT -fPIC -DSHARED_MODULE -I
/usr/lib/apache/include -I /usr/local/include/postgresql -c
module/mod_pref.c -o build/mod_pref.o
gcc -Wall -ggdb -O0 -O2 -pipe -DDEV_RANDOM=/dev/arandom
-DMOD_SSL=208116 -DEAPI -DUSE_SETUSERCONTEXT -fPIC -DSHARED_MODULE -I
/usr/lib/apache/include -I /usr/local/include/postgresql -c
module/pgsql.c -o build/pgsql.o
gcc -shared -fPIC -DSHARED_MODULE -L /usr/local/lib -lpq
build/mod_pref.o build/pgsql.o -o mod_pref.so
apxs -n pref -a -i mod_pref.so
When I add however these 3 lines to my mod_pref.c:
#include <apache_request.h>
....
ApacheRequest *req = ApacheRequest_new(r);
req->disable_uploads = 1;
And to the compile and linking commands above - corresponding:
-I /usr/local/libdata/perl5/site_perl/i386-openbsd/auto/libapreq/include
and
-L /usr/local/libdata/perl5/site_perl/i386-openbsd/auto/libapreq
-lapreq \
/usr/local/libdata/perl5/site_perl/i386-openbsd/auto/libapreq/libapreq.a
then the mod_pref.so does build, but I can't run the httpd anymore:
laptop:afarber {862} sudo /usr/sbin/httpd -X
/usr/sbin/httpd:/usr/lib/apache/modules/mod_pref.so: undefined
symbol 'ApacheRequest_new'
I'm thankful for any hints as I couldn't find the solution on the web yet
nor in the WRAPMOD book I own
Is maybe the OpenBSD package wrong and a shared library is missing?
Or do I maybe need to rebuild the httpd itself and link it against libapreq.a?
Regards
Alex
PS: Here some more info from my PC:
laptop:afarber {532} perl -MApache::libapreq -e ccopts
-I/usr/local/libdata/perl5/site_perl/i386-openbsd/auto/libapreq/include
laptop:afarber {533} perl -MApache::libapreq -e ldopts
-L/usr/local/libdata/perl5/site_perl/i386-openbsd/auto/libapreq -lapreq
PPS: And here is my Makefile (I don't use "apxs -c", because I want .o files
go into "build/" subdir and the target mod_pref.so into the top dir)
# PostgreSQL flags
PG_CFLAGS := -I $(shell pg_config --includedir)
PG_LDFLAGS := -L $(shell pg_config --libdir) -lpq
# Apache module flags
LIBAPREQ = /usr/local/libdata/perl5/site_perl/i386-openbsd/auto/libapreq
AP_CFLAGS := $(shell apxs -q CFLAGS) $(shell apxs -q CFLAGS_SHLIB) \
-I $(shell apxs -q INCLUDEDIR) -I $(LIBAPREQ)/include
AP_LDFLAGS := $(shell apxs -q LDFLAGS_SHLIB) \
-L $(LIBAPREQ) -lapreq $(LIBAPREQ)/libapreq.a
VPATH = media server module java-client
MODULE = mod_pref.c pgsql.c
MODOBJS = $(MODULE:%.c=$(BUILD)/%.o)
mod_pref.so: $(MODOBJS)
$(CC) $(AP_LDFLAGS) $(PG_LDFLAGS) $^ -o $@
$(MODOBJS): $(BUILD)/%.o: %.c mod_pref.h
$(CC) $(CFLAGS) $(AP_CFLAGS) $(PG_CFLAGS) -c $< -o $@
