[issue6237] Build errors when using LDFLAGS="-Wl,--no-undefined"
Funda Wang added the comment: Regarding python binary target, the actual command when linking is: gcc -pthread -Wl,--as-needed -Wl,--no-undefined -Wl,-z,relro -lstdc++ - Xlinker -export-dynamic -o python \ Modules/python.o \ -LL. -lpython2.6 -lpthread -ldl -lutil -lm The linking order is wrong. "-lstdc++" is LIBADD, it should appear after OBJECTS such as Modules/python.o. The same applies to -pthread. The command should looks like: gcc -Wl,--as-needed -Wl,--no-undefined -Wl,-z,relro -Xlinker -export- dynamic -o python \ Modules/python.o \ -LL. -lpython2.6 -lpthread -ldl -lutil -lm -lstdc++ -- ___ Python tracker <http://bugs.python.org/issue6237> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
