Hi list, I've been trying to install notmuch but I ran into problems related to talloc and, seemingly with notmuch's understanding of the talloc.h file. ./configure affirms that all needed headers are installed: [...] Checking for Xapian development files... Yes. Checking for GMime 2.4 development files... Yes. Checking for talloc development files... Yes. Checking for valgrind development files... No. [...] but then make complains: [...] CC lib/xutil.o CXX lib/database.o CXX lib/index.o CXX lib/message.o CXX lib/query.o CXX lib/thread.o AR lib/notmuch.a CXX notmuch notmuch.o: In function `main': notmuch.c:(.text+0x326): undefined reference to `_talloc_free' notmuch-config.o: In function `notmuch_config_set_user_other_email': notmuch-config.c:(.text+0x42): undefined reference to `_talloc_free' notmuch-config.o: In function `notmuch_config_close': notmuch-config.c:(.text+0x75): undefined reference to `_talloc_free' notmuch-config.o: In function `notmuch_config_set_user_primary_email': notmuch-config.c:(.text+0x1ab): undefined reference to `_talloc_free' notmuch-config.o: In function `notmuch_config_set_user_name': notmuch-config.c:(.text+0x1fb): undefined reference to `_talloc_free' notmuch-config.o:notmuch-config.c:(.text+0x24b): more undefined references to `_talloc_free' follow lib/notmuch.a(database.o): In function `_resolve_message_id_to_thread_id(_notmuch_database*, void*, char const*)': database.cc:(.text+0x186e): undefined reference to `_talloc_steal_loc' lib/notmuch.a(database.o): In function `_my_talloc_free_for_g_hash(void*)': database.cc:(.text+0x1a4c): undefined reference to `_talloc_free' lib/notmuch.a(database.o): In function `notmuch_database_add_message': database.cc:(.text+0x20e7): undefined reference to `_talloc_free' database.cc:(.text+0x216b): undefined reference to `_talloc_free' lib/notmuch.a(message.o): In function `_notmuch_message_create': message.cc:(.text+0x1ee): undefined reference to `_talloc_free' lib/notmuch.a(message.o): In function `_notmuch_message_create_for_message_id': message.cc:(.text+0x299): undefined reference to `_talloc_steal_loc' message.cc:(.text+0x372): undefined reference to `_talloc_free' lib/notmuch.a(message.o): In function `_notmuch_message_set_filename': message.cc:(.text+0xd9e): undefined reference to `_talloc_free' lib/notmuch.a(message.o): In function `_notmuch_message_add_term': message.cc:(.text+0x157e): undefined reference to `_talloc_free' lib/notmuch.a(message.o): In function `_notmuch_message_remove_term': message.cc:(.text+0x193b): undefined reference to `_talloc_free' lib/notmuch.a(message.o): In function `notmuch_message_destroy': message.cc:(.text+0x1b5a): undefined reference to `_talloc_free' lib/notmuch.a(query.o):query.cc:(.text+0x8fb): more undefined references to `_talloc_free' follow lib/notmuch.a(thread.o): In function `_thread_add_message(_notmuch_thread*, _notmuch_message*)': thread.cc:(.text+0x10c): undefined reference to `_talloc_steal_loc' lib/notmuch.a(thread.o): In function `notmuch_thread_destroy': thread.cc:(.text+0x854): undefined reference to `_talloc_free' lib/notmuch.a(message-file.o): In function `notmuch_message_file_close': message-file.c:(.text+0x5f5): undefined reference to `_talloc_free' collect2: ld returned 1 exit status make: *** [notmuch] Error 1 I have the talloc.h in /usr/include and talloc_free as well as _talloc_free is in there: % egrep "*talloc_free" /usr/include/talloc.h #define talloc_free(ctx) _talloc_free(ctx, __location__) #define talloc_destroy(ctx) talloc_free(ctx) #define TALLOC_FREE(ctx) do { talloc_free(ctx); ctx=NULL; } while(0) int _talloc_free(void *ptr, const char *location); void talloc_free_children(void *ptr); % Probably unusable system info: % uname -a Linux algorithm 2.6.31-ARCH #1 SMP PREEMPT Fri Oct 23 11:12:58 CEST 2009 i686 Intel(R) Core(TM)2 Duo CPU P9500 @ 2.53GHz GenuineIntel GNU/Linux What am I doing wrong?
