Does it work with default LDFLAGS?
(In reply to comment #3) > Does it work with default LDFLAGS? > Indeed it does, I forgot I had --as-needed in LDFLAGS.
Not sure what I'm doing wrong :) but --as-needed gave me no trouble for protobuf 2.1.0 on x86. $cat /var/db/pkg/dev-libs/protobuf-2.1.0/LDFLAGS -Wl,-O1,--as-needed,-z,now
Same here on amd64 with 2.2.0. Please reopen if you have any hints about how to reproduce it with 2.2.0.
This still affects 2.2.0a. ./.libs/libprotobuf.so isn't being compiled with -lpthread, even with the latest gcc (4.4.2) According to the man-page for gcc, "-pthread" is not supported for i386/x86_64 (i.e. it has no effect), so -lpthread should have been specified by libtool. Even the latest libtool (2.2.6b) does this wrong too.

Have you reported this to upstream too?
http://code.google.com/p/protobuf/issues/detail?id=188
*** Bug 320933 has been marked as a duplicate of this bug. ***
reopening, the current patch isn't enough (see also the upstream ticket)
Reassigning as I no longer maintain protobuf.
Created attachment 232441 [details, diff] fixing as-needed issues It was actual trivial bug in acx_threads, should be fine now.
ok, fixed in -r1, together with the addition of static-libs USE flag.
breaks darwin, #472514
ok, the real proper fix for this would be: a) make a patch for the maintained ax_pthread.m4 at http://git.savannah.gnu.org/cgit/autoconf-archive.git containing the changes made by protobuf devs (the part about detecting GCC inconsistencies) since this upstream already has sections for darwin b) have the protobuf devs change to use ax_pthread.m4 from a maintained source
