Hi, I am working on CentOS7 I am trying the 1.1 Very High Level Embedding I am using Python 3.7.3 (default, Mar 27 2019, 22:11:17) [GCC 7.3.0] :: Anaconda, Inc. on linux I created a file by pasting the tutorial code into original.c #define PY_SSIZE_T_CLEAN #include <Python.h> int main(int argc, char *argv[]) { wchar_t *program = Py_DecodeLocale(argv[0], NULL); if (program == NULL) { fprintf(stderr, "Fatal error: cannot decode argv[0]\n"); exit(1); } Py_SetProgramName(program); /* optional but recommended */ Py_Initialize(); PyRun_SimpleString("from time import time,ctime\n" "print('Today is', ctime(time()))\n"); if (Py_FinalizeEx() < 0) { exit(120); } PyMem_RawFree(program); return 0; } After executing: gcc -o original original.c original.c:2:20: fatal error: Python.h: No such file or directory #include <Python.h> ^ compilation terminated. What am I doing wrong? Is the tutorial complete? Thanks, Jesse
