MQX 4.0.1 program Not Compiled with GCC

[yogesh8418]

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

error

Description	Resource	Path	Location	Type
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.......

Thanks

Hello yogesh patel,

what demo have you executed? Can you share console output?

How did you change compiler?

Hi martin

I am just executing the hello world example in the mqx example folder as shown in the picture below.

and the error is shown below in the picture.

You have to build MQX libraries for GCC compiler first, before an application. Drag and drop

c:\Freescale\Freescale_MQX_4_0\config\twrk20d72m\cw10gcc\twrk20d72m.wsd

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?

Thanks

Hello,

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.

Ok,

thanks.

So, I will wait MQX 4.1

In this moment I'm using MQX 4.0.2 + patch (FSLMQXOS_4_0_2_GA.exe + MQX_4.0.2.2_PATCH.zip)

Thanks again
