Mbed-os: cstddef: No such file or directory

mbed-os/platform/platform.h:22:19: fatal error: cstddef: No such file or directory

I cloned this repository and tried to compile this program:

/**
 * Nucleo program that does not do anything. Test of basic compilation. 
**/

#include <mbed.h>
void main()
{

}

With this command:

arm-none-eabi-gcc main.c --specs=nosys.specs -I../../software/mbed-os/

Where ../../software/mbed-os/ is path to the root of this repository. The error I get:

In file included from ../../software/mbed-os/mbed.h:51:0,
                 from main.c:5:
../../software/mbed-os/platform/platform.h:22:19: fatal error: cstddef: No such file or directory
compilation terminated.

The version of my compiler:

>arm-none-eabi-gcc --version
arm-none-eabi-gcc (GNU Tools for ARM Embedded Processors) 5.4.1 20160919 (release) [ARM/embedded-5-branch revision 240496]

I'm running this all on Windws 7 x64 and Debian 8 Jessiex64 with same result. I found some vague mentions of something called private_settings.py in some forum threads, but nobody really bothered to explain what is that supposed to do.

@Darker We have a hal that includes code and header files for many targets, and many features in the code that can be turned on and off. Further, we have a few more arguments to gcc than just --specs=nosys.specs. As such we have a bunch of tools that run the compiler for us. Please use the pip package mbed-cli to compile.

Further, we use GCC version 4.9.3.

Finally, it looks like you are missing system header files. But I'm not sure this is even the real problem here. Could you try changing your GCC version and using mbed-cli first?

[toyowata]

@Darker The cstddef is C++ header file. Can you rename your source file from main.c to main.cpp?

Hi, I do have this problem:

$ mbed new mbed-os-program
$ cd mbed-os-program
$ mbed compile -t GCC_ARM -m NUCLEO_F746ZG -v
[Fatal Error] platform.h@22,19: cstddef: No such file or directory

$ sudo mbed config --list
[mbed] Global config:
GCC_ARM_PATH=/usr/bin
ARM_PATH=/home/jack/apps/gcc-arm-none-eabi-7-2017-q4-major

[mbed] Local config (/home/jack/mbed/mbed-os-program):
No local configuration is set

cstddef: No such file or directory
How can I solve this?

[0xc0170]

GCC_ARM_PATH=/usr/bin

what gcc is there ? the ARM path points to gcc (use GCC 6 as that one is supported). T hus I would fix GCC_ARM_PATH to point to GCC ARM 6 version

[bkht]

Hi, thank you very much for helping me!
I now have
$ arm-none-eabi-gcc --version
arm-none-eabi-gcc (GNU Tools for Arm Embedded Processors 7-2017-q4-major) 7.2.1 20170904 (release) [ARM/embedded-7-branch revision 255204]
So, I need to install arm-none-eabi-gcc v6 better?

I looking where to download v6.... and update once I know...

[pan-]

@bkht what type of file triggers the error ? C or C++ ?

[0xc0170]

On
https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads
Only version 7 is listed...
Where can I get v6?

scroll down more, 6 is there

[bkht]

Many thanks!!!

Hi, I just installed gcc 6.3.1

$ arm-none-eabi-gcc --version
arm-none-eabi-gcc (GNU Tools for ARM Embedded Processors 6-2017-q2-update) 6.3.1 20170620 (release) [ARM/embedded-6-branch revision 249437]

$ sudo mbed config -G ARM_PATH "/home/jack/apps/gcc-arm-none-eabi-6-2017-q2-update-linux"
$ sudo cp /home/jack/apps/gcc-arm-none-eabi-6-2017-q2-update-linux/bin/arm-none-eabi-gcc /usr/bin/.
$ sudo mbed config -G GCC_ARM_PATH "/usr/bin"

$ arm-none-eabi-gcc --version
6.3.1

$ sudo mbed config --list
[mbed] Global config:
GCC_ARM_PATH=/usr/bin
ARM_PATH=/home/jack/apps/gcc-arm-none-eabi-6_2-2016q4

[mbed] Local config (/home/jack/mbed/mbed-os-program):
TOOLCHAIN=GCC_ARM
TARGET=NUCLEO_F746ZG

But the result is the same:

$ mbed compile -v
[Fatal Error] platform.h@22,19: cstddef: No such file or directory

I also tried 6.2.1
What else can I verify to correct the problem?

[0xc0170]

@bkht what type of file triggers the error ? C or C++ ?

If you can answer this question, where is the error coming from (not only what header file).

[bkht]

Hi, this is the complete output, hope that helps (unfortunately, it's not clear to me):

@bkht You may need arm-none-eabi-newlib or similar to get the c std lib.

[bkht]

I use Linux Mint 18.1
$ uname -a
Linux GS72 4.4.0-59-generic #80-Ubuntu SMP Fri Jan 6 17:47:47 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
How do I install 'arm-none-eabi-newlib'? I searched, but no luck.

[pan-]

@bkht The following lines are suspicious:

$ sudo cp /home/jack/apps/gcc-arm-none-eabi-6-2017-q2-update-linux/bin/arm-none-eabi-gcc /usr/bin/.
$ sudo mbed config -G GCC_ARM_PATH "/usr/bin"

Why do you copy manually arm-none-eabi-gcc into /usr/bin/ ? A compiler is not just a binary, it come with a linker, headers files, object files, library files, ...

If you have extracted GCC in /home/jack/apps/gcc-arm-none-eabi-6-2017-q2-update-linux/ then you can set GCC_ARM_PATH to /home/jack/apps/gcc-arm-none-eabi-6-2017-q2-update-linux/bin:

sudo mbed config -G GCC_ARM_PATH "/home/jack/apps/gcc-arm-none-eabi-6-2017-q2-update-linux/bin"

[bkht]

Thank you! That actually works better. I still have problems, but I will first try different versions of the compiler.

@bkht the main function is not defined by mbed OS; it shall be defined by your application. Add the following code in a file named main.cpp in the root or your project:

#include "mbed.h"

DigitalOut led1(LED1);

// main() runs in its own thread in the OS
int main() {
    while (true) {
        led1 = !led1;
        wait(0.5);
    }
}

This application should blink your board LED every 500ms.

[bkht]

Thank you very much!, Now it all works!
I didn't even notice main.ccp was not in there, as I was trying to test my toolchain installation. :-)
Many thanks!
