The -Wl,--dynamic-list test is currently broken on Fedora 23, when you
configure with --with-python=python3.4. We see:
configure:13741: checking for the dynamic export flag
configure:13796: gcc -o conftest -g3 -O0 -fno-strict-aliasing -DNDEBUG -fwrapv -Wl,--dynamic-list=/home/pedro/gdb/mygit/src/gdb/proc-service.list conftest.c -ldl -lncurses -lm -ldl -lpthread -ldl -lutil -lm -lpython3.4m -Xlinker -export-dynamic >&5
conftest.c:182:30: fatal error: python3.4/Python.h: No such file or directory
compilation terminated.
configure:13796: $? = 1
The correct -I path is in PYTHON_CPPFLAGS:
PYTHON_CPPFLAGS='-I/usr/include/python3.4m -I/usr/include/python3.4m'
(Other Python-related tests in the file are already doing this.)
gdb/ChangeLog:
yyyy-mm-dd Pedro Alves <palves@redhat.com>
* configure.ac (checking for the dynamic export flag): Add
$PYTHON_CPPFLAGS to CPPFLAGS.
* configure: Regenerate.
