4 years ago Hi YiGene, Related to this I wrote this simple CMakelists.txt in order to create Visual Studio solutions using CMake tool and it seems it can also be compiled and it works ok, just if it is of interest.

CONFIGURE_FILE("${PROJECT_SOURCE_DIR}/config.cmake.in" "${PROJECT_BINARY_DIR}/modbusConfig.cmake" @ONLY)config.cmake.in is the file used to create modbusConfig.cmake (used by FindPackage to generate configuration variables). Here the content:

# - modbus_INCLUDE_DIRS : The directory where include files are.
# - modbus_VERSION : The version of this build. Example: "1.2.0"
# - modbus_VERSION_MAJOR : Major version part of VERSION. Example: "1"
# - modbus_VERSION_MINOR : Minor version part of VERSION. Example: "2"
# - modbus_VERSION_PATCH : Patch version part of VERSION. Example: "0"

it take me some time to get it build to 64bit under 2015 hence i put a note here
after we choose x64 to debug and release, run build
we see below errors: 1> d:\modbus\libmodbus-3.1.6\src\modbus.h(228): note: see previous definition of 'modbus_mapping_free' 1> Generating Code... 1> Link: 1> Creating library D:\modbus\libmodbus-3.1.6\src\win32\x64\Debug\modbus.lib and object D:\modbus\libmodbus-3.1.6\src\win32\x64\Debug\modbus.exp 1> 1> 1>modbus-rtu.obj : warning LNK4217: locally defined symbol modbus_free imported in function modbus_new_rtu 1> 1> 1>modbus-tcp.obj : warning LNK4217: locally defined symbol modbus_free imported in function _modbus_tcp_init_win32 1> 1> 1>modbus.obj : warning LNK4217: locally defined symbol modbus_set_bits_from_bytes imported in function modbus_reply 1> 1> 1>modbus-data.obj : error LNK2019: unresolved external symbol __imp_htonl referenced in function modbus_set_float_abcd 1> 1>
add ws2_32.lib
build success
PLEASE NOTE i didn't test the function, just build it
