This is more a question rather than an issue. I'm trying to compile GetStarted without Visual Studio. The example works perfectly well in remote-debugging mode of Visual Studio, but when I try to compile it manually on board, I get a segmentation fault in alt_gpio_init(). It might be due to command line flags that I am using.
I think I figured out this one. One should not use hps.h included in Linux_alt_lib/altera_hps/hwlib, but the one in /usr/include/socal, and define LINUX_TASK_MODE. It works now.

The Makefile is:
TARGET = main
# ALT_DEVICE_FAMILY ?= soc_cv_av HWLIBS_ROOT = Linux_alt_lib/altera_hps/hwlib
CROSS_COMPILE = arm-linux-gnueabihf-
CPPFLAGS = -g -Wall -D$(ALT_DEVICE_FAMILY) -I$(HWLIBS_ROOT)/include/$(ALT_DEVICE_FAMILY) -I$(HWLIBS_ROOT)/include/ -I.. -Wformat=0 -std=c++11 CCFLAGS = -g -Wall -D$(ALT_DEVICE_FAMILY) -I$(HWLIBS_ROOT)/include/$(ALT_DEVICE_FAMILY) -I$(HWLIBS_ROOT)/include/ -I.. -Wformat=0 LDFLAGS = -g -Wall -lpthread CXX = $(CROSS_COMPILE)g++ CC = $(CROSS_COMPILE)gcc ARCH= arm
CFILES = $(wildcard *.c) OBJECTS = $(CFILES:.c=.o)
build: $(TARGET) $(TARGET): main.o $(OBJECTS) $(CXX) $(LDFLAGS) $^ -o $@ %.o : %.cc $(CXX) $(CPPFLAGS) -c $< -o $@ %.o : %.c $(CC) $(CCFLAGS) -c $< -o $@
.PHONY: clean clean: rm -f $(TARGET) .a .o *~
I compile main.cpp and alt_generalpurpose_io.c
