compile / make file error HELP !!! ?

[Alex Angel]

Hi all,

Anybody an idea ? Trying to compile APM quadcopter with latest nuttx v7.xx

Nuttx part done, PX4 done , APM I think is done ... 

This came up :

 /opt/gcc-arm-none-eabi-4_9-2015q3/arm-none-eabi/include/c++/4.9.3/bits/postypes.h:227:16: error: 'mbstate_t' was not declared in this scope

   typedef fpos<mbstate_t> streampos;

                

compilation terminated due to -Wfatal-errors.

make[3]: *** [uORBDevices_nuttx.cpp.o] Error 1

make[3]: Leaving directory `/home/lexx/ArduPilot/ardupilot/modules/PX4Firmware/Build/px4fmu-v2_APM.build/home/lexx/ArduPilot/ardupilot/modules/PX4Firmware/src/modules/uORB'

make[2]: *** [/home/lexx/ArduPilot/ardupilot/modules/PX4Firmware/Build/px4fmu-v2_APM.build//home/lexx/ArduPilot/ardupilot/modules/PX4Firmware/src/modules/uORB/module.pre.o] Error 2

make[2]: Leaving directory `/home/lexx/ArduPilot/ardupilot/modules/PX4Firmware/Build/px4fmu-v2_APM.build'

make[1]: *** [/home/lexx/ArduPilot/ardupilot/modules/PX4Firmware/Build/px4fmu-v2_APM.build/firmware.px4] Error 2

make[1]: Leaving directory `/home/lexx/ArduPilot/ardupilot'

make: *** [px4-v2] Error 2

But

mbstate_t was included in mchar.h file and posttypes.h also include the mchar.h file

Any suggestion or perhaps even HELP would be appreciate

Alex,

 

     This is the issue:  https://github.com/ArduPilot/ardupilot/issues/4532

 

     There’s a temporary fix here:  https://github.com/ArduPilot/ardupilot/pull/4528

 

     Sid is working on a new windows toolchain which includes the updated gcc compiler.  I’ve already tested it and it works but we need to fix the directory that it’s installing to and then we will make the new .msi available.

Randy, from what I can see it's totally different issue. He appears to be using Linux and gcc 4.9 which is not affected by that bug.

Alex, if I understood you correctly you are trying to change the nuttx submodule to a different version, is that right?

Hello Lucas,

Yes I'm building apm quadcopter firmware with latest nuttx version. Not just PX4. 

There is a px4 version out there. Im also trying to port APM to work with this latest nuttx since I didn't see any version of APM out there to work with nuttx v7.xx

Hello Randy,

So are you sure this is the problem? Like Lucas mentioned here I'm using linux not windows. Does this also affects the toolchain on linux or what ... ?

Alex,

 

     I’m sure Lucas is correct, that I was mixing up the issues.

[Alex Angel]

Hy,

Well I don't know who is actually right or not I still didn't solve this. I tried with the different toolchain and still failed.

Lucas wanted to suggest something else .... I guess ....

Any idea ?

Hi Alex,

We never build with a version of nuttx that is not the one we support
in https://github.com/ArduPilot/PX4Nuttx

Adding support for a newer version of nuttx is nice, but it's not
something we deal with daily. I think the first step would for you to
detail how you are doing it and how we could reproduce it. From your
log it seems to be a toolchain problem, but could be something else.

Ok so what do you need to know or what do you think the problem is related to?

Before that I had some errors with the I2C frequency .. but solved them,

When trying to build on newest nuttx I got mostly errors related to file structure.

If this error is related to toolchain can somebody please explain to me why ?

Toolchain as far as I know are provided by ARM manufacturer. Why are there different toolchains out there or different versions ?

I can understand you have toolchain for running on linux or windows etc ... But I understand there are different versions out there ? 

Who makes them and why does APM team has anything to do with it ? If its the toolchain for arm cross compile then there should be just 1 PERFECT toolchain available from ST itself.

This part is what really is confusing and don't understand what Randy was saying about this kind of errors and that they need to make a new one ...

I suggest you to build with the nuttx version we support before trying
to update it to a version we don't. Please follow the wiki on
dev.ardupilot.org on how to build it.

It could be related to toolchain, to nuttx, to px4, to a lot of things
we don't support. We support the nuttx version I pointed out. If you
want to update nuttx you will need to go through all the odds and bugs
that that entails.

real world vs ideal world. unfortunately it's not like this.

Hello,

Yes thats what Im trying to do, so that's why I asked for help. I do not want to use the older nuttx or the one currently supported. I need to go through with this and I'm very close to the finish.

Can somebody tell me what this error is related to or how to fix it ? Do you know perhaps what this error is for Lucas ? Like I mentioned this question was trying to solve the error not going backwards.

Hello randy,


could this be the reason why ? 

https://webcache.googleusercontent.com/search?q=cache:http://comments.gmane.org/gmane.comp.embedded.nuttx/7508

and porting an implementation of the libstdc++ to NuttX ?

could this be a soltuion ? https://gcc.gnu.org/gcc-5/changes.html

Hi,

I am not sure that uOrb is used in APM, but it use in PX4 flightstack : look here :
