I am using TWR-K20D72M and I opened a Sample program (Freescale\Freescale_MQX_4_0\mqx\examples\hello ) which is given in the MQX 4.0.1 Demo examples. When I choose Build tool option as Freescale
the program compiles OK but When I choose Build tool option as GCC It gives me error.The Error is below
|mingw32-make: *** No rule to make target `C:/Freescale/Freescale_MQX_4_0/lib/twrk20d72m.cw10gcc/debug/bsp/intflash.ld', needed by `explicit-dependencies'.||MQX_MODBUS_TEST1||C/C++ Problem|
I read somewhere that The GCC can only work with MQX 4.0.1 and above so I am using MQX 4.0.1 .
Can some suggest me the reason for this error.How I can I remove this error.......
You have to build MQX libraries for GCC compiler first, before an application. Drag and drop
into your Project window in CW 10.4 IDE and build the MQX libraries. At post built step, the linker command file will be copied from the bsp folder to the lib folder. Then build the example application.
Hi. I have opened this C:\Freescale\Freescale_MQX_4_0\config\twrk70f120m\cw10gcc\twrk20d72m.wsd
and I tried to compile BSP project. The result is a lot of warnings (117).

How Can I solve this?
warnings by MQX library build will be removed in next MQX version. For the moment, unless you make changes to the BSP source code, you may focus on your application.
