Compilation Issue while configuring Data Collection Manager(DCM) for board LS1021

nikhilkumar — Tue, 14 Jun 2016 09:56:23 GMT

Hi,

I am trying to enable the configuration to include the DCM driver in the kernel and compile image for the board LS1021, but i am getting the compilation error as :

"| drivers/misc/fsl_dcm.c: In function 'write_sram':

| drivers/misc/fsl_dcm.c:83:2: error: implicit declaration of function 'out_8' [-Werror=implicit-function-declaration]

| out_8(dcm->addr, offset);

| ^

| drivers/misc/fsl_dcm.c: In function 'read_sram':

| drivers/misc/fsl_dcm.c:94:2: error: implicit declaration of function 'in_8' [-Werror=implicit-function-declaration]

| return in_8(dcm->data);

| ^".

Please provide inputs how to resolve this issue.

Implicit declaration means the compiler detected this function usage in your code, but the function is not declared yet.

This is not a mistake, if the function is declared later. If this function is never declared, there should be an error reported.

Have a great day,
Alexander
