Hello,

it seems that you successfully shared your directory - but maybe the write access is disabled. Please check the settings of the shared folder.

Does it work?

Best regards,

Thanks Manfred for your quick reply,

I have given read/write access to that folder ..

on other hand as well i tried using sudo chmod a+w to remove wirte protection on directories and allow make file to create obj directory and others but with no luck.

i am super rookie in embedded systems but trying to learn.

Hello All, 

I have managed to solve it by removing the dot before /obj and modified it in the make file to look like below:

###############################################################################
# GENERAL SETTINGS & PATHS
###############################################################################
EMWI_APP_PATH     = ../GeneratedCode

SRC_PATH          = ../Source

EMWI_RTE_PATH     = ../../PlatformPackage/RTE
EMWI_GFX_PATH     = ../../PlatformPackage/RGBA8888
EMWI_BSP_PATH     = ../../TargetSpecific
WIRINGPI_PATH     = /home/pi/wiringPi/wiringPi
OBJ_PATH          = /obj
BIN_PATH          = .

SDK_PATH          = /opt/vc
LIB_PATH          = $(SDK_PATH)/lib
 

but now i am faced with another error as follows that i am trying to solve as well

Best Regards

Hello Kasem,

well, now the object files are stored on the RasPi and not on the shared directory of the Windows PC. Please try to get a proper write access to the shared folder - there should be no need to "fix" the makefile...

Best regards,

Manfred.

Hello Manfred,

Thanks a lot for your reply,

I have managed to solve it by changing the make file Bin path as follows:

###############################################################################
# GENERAL SETTINGS & PATHS
###############################################################################
EMWI_APP_PATH     = ../GeneratedCode

SRC_PATH          = ../Source

EMWI_RTE_PATH     = ../../PlatformPackage/RTE
EMWI_GFX_PATH     = ../../PlatformPackage/RGBA8888
EMWI_BSP_PATH     = ../../TargetSpecific
WIRINGPI_PATH     = /home/pi/wiringPi/wiringPi
OBJ_PATH          = /obj
BIN_PATH          = /usr/bin

SDK_PATH          = /opt/vc
LIB_PATH          = $(SDK_PATH)/lib

 

Best Regards
