Я сгенерировал код c, используя cython, из файла helloworld.py:
print("Hello World")
с помощью:
cython --embed helloworld.py
Затем я попытался скомпилировать его, используя GCC 7.3.0 в Ubuntu 18.04 с Python 3.6, и пакеты python-dev, python3-dev, установленные с помощью:
gcc `/usr/bin/python3-config --cflags --ldflags` helloworld.c -o helloworld
/usr/bin/python3-config --cflags --ldflags возвращается следующим образом:
-I/usr/include/python3.6m -I/usr/include/python3.6m -Wno-unused-result -Wsign-compare -g -fdebug-prefix-map=/build/python3.6-EKG1lX/python3.6-3.6.5=. -specs=/usr/share/dpkg/no-pie-compile.specs -fstack-protector-strong -Wformat -Werror=format-security -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -L/usr/lib/python3.6/config-3.6m-x86_64-linux-gnu -L/usr/lib -lpython3.6m -lpthread -ldl -lutil -lm -Xlinker -export-dynamic -Wl,-O1 -Wl,-Bsymbolic-functions
и вся команда заканчивается так:
/usr/bin/x86_64-linux-gnu-ld: /tmp/ccuXRvp5.o: relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIC
/usr/bin/x86_64-linux-gnu-ld: final link failed: Nonrepresentable section on output
collect2: error: ld returned 1 exit status
Кто-нибудь знает, как обойти эту проблему?
PS: я пытался запустить:
gcc `/usr/bin/python3-config --cflags --ldflags` -fPIC helloworld.c -o helloworld
но это заканчивается так:
