c - Is libsasl2 broken on OSX Yosemite? Missing sasl_client_done -

i've been having problem installed version of libsasl2 (cyrus sasl).

in particular, seems local headers , sasl_version study version 2.1.26, no symbol provided global function sasl_client_done.

i'm pretty sure i'm supposed have symbol because:

it's there in provided sasl/sasl.h header the cyrsus sasl news file lists "implemented sasl_client_done()/sasl_server_done()" 2.1.24 feature it's there everywhere provides 2.1.26 outside of yosemite

for reproduction:

note sample below prints "impl: 'cyrus sasl', version: 33619994, major: 2, minor: 1, step: 26" the sample compiles , executes on linux install same library version after uncommenting code

the uncommented code produces link error on yosemite

undefined symbols architecture x86_64: "_sasl_client_done", referenced from: _main in foo-072675.o ld: symbol(s) not found architecture x86_64 clang: error: linker command failed exit code 1 (use -v see invocation)

invoking compiler with:

clang -wall -werror -lsasl2 -o foo foo.c -v

with clang -v of:

and code in question:

#include <sasl/sasl.h> #include <stdio.h> #include <stdint.h> int main(int argc, char ** argv) { const char *impl; int version; uint32_t buf; uint16_t major; uint8_t minor; uint8_t step; sasl_version(&impl, &version); buf = version; major = buf >> 24; minor = (buf << 8) >> 24; step = (buf << 24) >> 24; printf("impl: '%s', version: %d, major: %d, minor: %d, step: %d\n", impl, version, major, minor, step); /* { int (* scd)(void); scd = &sasl_client_done; printf("sasl_client_done: %p\n", scd); } */ homecoming 0; }

i'm thinking something's screwy way cyrus sasl got packaged yosemite (using symbol list mavericks perhaps?).

as matter of interest, checked 10.10.4 , see symbol there:

$ nm /usr/lib/libsasl2.dylib |grep sasl_client_done 000000000000724a t _sasl_client_done

the sample code works fine (with commented section uncommented). same cyrus sasl version still returned though:

impl: 'cyrus sasl', version: 33619994, major: 2, minor: 1, step: 26 sasl_client_done: 0x7fff8e3dc24a

c osx osx-yosemite sasl
