KSDK Linker Error - Command line too long

[larrykoos]

I'm using KDS 1.1.1 with MQX_KSDK 1.0.0. I've built a project with Processor Expert targeting a K64 part. After using the project successfully for several weeks, I have reached a point where I get a linker error such as:

arm-none-eabi-g++: error: C:/Freescale/KDS_1.1.1/eclipse//../toolchain/arm-none-eabi/lib/m4fp/v4-sp-d16/libm.a: No such file or directory

Through experimentation, I have determined this error is caused by a linker command line that exceeds a maximum threshold. Here is an example of the command line auto-generated by the tool:

arm-none-eabi-g++ -mcpu=cortex-m4 -mthumb -mfloat-abi=hard -mfpu=fpv4-sp-d16 -O0 -fmessage-length=0 -fsigned-char -ffunction-sections -fdata-sections  -g3 -T

Clearly, the right way to fix this is to make a library of MQX and link in the library to the application, but I can't figure out how to do this without breaking the Processor Expert environment. Can anyone tell me the correct process?

Thanks.

tried:

new project, added ksdk_platform_lib.a to the linker path.

added (manually) all the KSDK/platform files (only the .h) putting all in the same folder ( Hal and Driver), so the includes are less. In the C and C++ compiler settings I added all the necessary path but when i compile cpp files a get an error like this:

In file included from C:\Users\jack\Dropbox\MBD\Progetti\TwingTec\Firmware\workspace\firmware\Sources\Includes\Hal/fsl_pit_hal.h:33:0,

                 from C:\Users\jack\Dropbox\MBD\Progetti\TwingTec\Firmware\workspace\firmware\Sources\Init/Cpu.h:82,

                 from C:\Users\jack\Dropbox\MBD\Progetti\TwingTec\Firmware\workspace\firmware\Sources\Init/UART3.h:69,

                 from ../Sources/SBUS.h:24,

                 from ../Sources/Futaba_sbus/FUTABA_SBUS.h:4,

                 from ../Sources/Futaba_sbus/FUTABA_SBUS.cpp:1:

C:\Users\jack\Dropbox\MBD\Progetti\TwingTec\Firmware\workspace\firmware\Sources\Includes\Hal/fsl_pit_hal.h: In function 'bool PIT_HAL_GetIntCmd(uint32_t, uint32_t)':

C:\Users\jack\Dropbox\MBD\Progetti\TwingTec\Firmware\workspace\firmware\Sources\Includes\Hal/fsl_pit_hal.h:287:22: error: 'FSL_FEATURE_PIT_TIMER_COUNT' was not declared in this scope

     assert(channel < FSL_FEATURE_PIT_TIMER_COUNT);

so it seems that it can't find the FSL_FEATURE_PIT_TIMER_COUNT #define that is in fsl_pit_features.h THAT IS IN SAME DIRECTORY AS fsl_pit_hal.h.

Any ideas?

[giacomopetrini]

Ok, found. I forgot to add the CPU type to the C++ preprocessor... ("CPU_MK64FN1M0VMD12").

[larrykoos]

Erich,

As far as I know, its not possible to build MQX as a library and continue to use PE. Is this correct or is there a way to do it?

Also, is there a way to get the tool to auto-generate the file used to pass a list of files to the linker?

[arwedspringer]

I have the same problem since yesterday.

Is there any known solution yet?

Thanks for any help.

[larrykoos]

No. We determined yesterday that it is not as simple as the command line being too long. We have another project that produces a longer command line but it links correctly. This morning we will try to verify that the problem is machine independent by building the problem on another laptop. Please let me know if you learn anything as well. Thanks.

[arwedspringer]

I figured out that exactly ONE character is removed from the command line string, which is always at the same position!

I added three dummy characters to the path string which was not found anymore. In the result the position where the character is missing has moved by three!

So I added a long empty entry in     property setting > Cross ARM C++ Link > Miscellaneous   just before the library which isn't found and now the linking works fine again.

(see the picture)

I know, this is just a quick hack but it works for the moment until the bug is fixed.

[giacomopetrini]

:smileyshocked:

ok, good to know.

Bye Giacomo

[arwedspringer]

I just had a look at the command line.

The missing character is exactly at position 8192 of the parameter string (whithout the command "arm-none-eabi-g++") 

So it seams that there is a problem if the created parameter string is greater than 8k bytes...

Bye Springer

[larrykoos]

This hack works on my project as well. Hopefully someone with more knowledge with the tool can help out here and give us a real fix.

Really good catch. Thanks.
