Comment #37 on issue 188 by [email protected]: protobuf fails to link
after compiling with LDFLAGS="-Wl,--as-needed" because of missing -lpthread
http://code.google.com/p/protobuf/issues/detail?id=188
i tried most recent official source release protobuf-c-0.15 on cygwin.
it failed with the the same symptom.
then i applied the below work around (just killing the exit statements from
configure), successfully configured and compiled the package - now its
operable for me at least up to the command line help (no deeper testing
done so far).
i want to share this result as it might help others in going ahead in a
timely fashion with their true targets. i dont want to imply it will work
all the time but it should work often on a normally working system despite
those error popped up.
----
what else to say? g++ used in the linker stage seems to benignly ignore
unknown options. "g++ (GCC) 4.3.4 20090804 (release) 1"
libtool: link: g++ -g -O2 -pthread -o .libs/cxx-generate-packed-data.exe
cxx-generate-packed-data.o test-full.pb.o /usr/local/lib/libprotobuf.a -lz
/usr/lib/gcc/i686-pc-cygwin/4.3.4/libstdc++.dll.a -pthread
-L/usr/lib/gcc/i686-pc-cygwin/4.3.4
g++: unrecognized option '-pthread'
g++: unrecognized option '-pthread'
