Building curl 7.55.1 with the following:
./configure --with-ssl=$install_path/openssl_64 --enable-shared=no --without-libidn --without-ldap-lib --without-zlib

When I attempt to build and link curl to a test application, I get:

../../PLUSNative/Debug32/libPLUSNative.so: undefined reference to `pthread_detach'

../../PLUSNative/Debug32/libPLUSNative.so: undefined reference to `pthread_join'

../../PLUSNative/Debug32/libPLUSNative.so: undefined reference to `pthread_create'

collect2: error: ld returned 1 exit status

Adding -pthread to the compiler options of the test app fixes the issue, but I never needed to do this before (we've been using curl for years).

I rolled back and tested with 7.55.0 and it works with no issues. Going through the changelog I see one difference is --enable-threaded-resolver is defaulted to on. Unfortunately, there is a bug where I cannot turn it off (without the patch). I'm curious if I am on the right track here with the issue? Could it be due to the threaded resolver being on?
