I have a python file that I want to run on the board. Hence I want to embed the python interpreter (written in C) in the board. I managed to write separate C project that runs the Python file. It compiles and runs as I want to. Here's the makefile for same. TM4c1294XL; http://www.kynix.com/…C1294XL.html

CC=gcc
CFLAGS=-I python3.5 -I config -I . -c -w
LDFLAGS= -lpython3.5m -lpthread -ldl -lutil -lm -Xlinker -export-dynamic -Wl,-O1 -Wl,-Bsymbolic-functions

all: classifier trainer test link

test:
$(CC) $(CFLAGS) test.c

trainer: Trainer.c
$(CC) $(CFLAGS) Trainer.c
$(CC) Trainer.o $(LDFLAGS) -o Trainer

.ONESHELL:
classifier: Classifier.c
$(CC) $(CFLAGS) Classifier.c
# $(CC) Classifier.o $(LLFLAGS) -o Classifier

link:
$(CC) test.o Classifier.o $(LDFLAGS) -o test

clean:
rm -f Trainer.o Trainer Classifier.o Classifier
http://dpaste.com/3BCY2RE is my entire directory of project "hello" (It is not the one from the examples).

I included "Classifier.h" in my "hello.c" and I am getting the following errors:" http://dpaste.com/3KKCF84": http://dpaste.com/3KKCF84

Compiler include options (No preincludes):

"${CG_TOOL_RO­OT}/include"
"${workspace_loc:/${Pr­ojName}/Terra­inPredict}"
"${workspace_loc:/${Pr­ojName}/Terra­inPredict/con­fig}"
"${workspace_loc:/${Pr­ojName}/Terra­inPredict/pyt­hon3.5}"
"${SW_ROOT}/e­xamples/boards/ek-tm4c1294xl"
"${SW_ROOT}"
Linker file search paths:

"libc.a"
"${workspace_loc:/${Pr­ojName}/Terra­inPredict/lib­terrainclf.a}"
"${SW_ROOT}/dri­verlib/ccs/De­bug/driverlib­.lib"
and:

"${CG_TOOL_RO­OT}/lib"
"${workspace_loc:/he­llo/TerrainPre­dict/libterra­inclf.a}"
"${CG_TOOL_RO­OT}/include"
Am I wrong with some of my configurations? Or is this some problem with python interpreter? Any help is greatly appreciated

As @KevinDTimm suggested, the problem is that there is no pyconfig.h for my environment. This file is required by python to define important variables like source of system clock. I tried removing safety checks in existing pyconfig.h. The first error I am getting is in pytime.h as :

"_PyTime_t need signed 64-bit integer type"
Which was further because of the following code block:

#ifdef PY_INT64_T
/* _PyTime_t: Python timestamp with subsecond precision. It can be used to
store a duration, and so indirectly a date (related to another date, like
UNIX epoch). */
typedef PY_INT64_T _PyTime_t;
#define _PyTime_MIN PY_LLONG_MIN
#define _PyTime_MAX PY_LLONG_MAX
#else
# error "_PyTime_t need signed 64-bit integer type"
#endif
It appears to me that it needs a variable that stores time. I need help in assigning that variable.
