Thanks guys. Sorry for the confusion. I thought "U" meant undefined and "T" meant it *belongs* in the text section, NOT that it actually *exists* in the text section :)
Here is my linker command. g++ -g -o unit_tests unit_tests.o -L/home/user/build/openssl/debug/lib -lcrypto -lssl --L/home/user/build/libcurl/debug/lib -lcurl -ldl -lstdc++ -lpthread -lrt -lz -lstdc++ When I built libcurl, I specified the --with-ssl=/.../ flag to point to my openssl build.
