Question

Hello,

new SDK (RUT9_R_GPL_00.07.03) contains libmodbus + couple of patches.

One of them changes the interface to original libmodbus => not possible to compile previously developed software.

...

-MODBUS_API int modbus_read_registers(modbus_t *ctx, int addr, int nb, uint16_t *dest);

-MODBUS_API int modbus_read_input_registers(modbus_t *ctx, int addr, int nb, uint16_t *dest);

+MODBUS_API int modbus_read_registers(modbus_t *ctx, int addr, int nb, uint8_t *dest);

+MODBUS_API int modbus_read_input_registers(modbus_t *ctx, int addr, int nb, uint8_t *dest);

...

How to keep original libmodbus in a build system and properly link the software ?

thank you,

A.B.

Hello,

Below is a brief suggestion from the developers:

"If you want to keep original interfaces, then probably the easiest way is to add another libmodbus package without patches and name it like libmodbus_org (or something like that) and link your previously developed software with libmodbus_org.

Another option is to update your developed software with our patches."

Best regards,
