As I mentioned in previous reply. SES stripped out most C++ headers. This from CrossWork itself but CrossWorks allows you to setup to use external full GCC. SES is a tripped down version of CrossWorks, not sure it supports that. So forget SES if you want to use C++.

SES stripped out most of the header files for C++ from GCC. hence does not compile C++ code. You need to use external full GCC for that.

you should really come up now with C++, it is totally anoying to program in C. Archaic C is in big discrepancy with the complexity of projects you do using NRF91 chips. Please go ahead with this. And stop finding excuses.

Best regards from Switzerland and sorry for the hard, but true words.

Hi LordLucan,

I can not comment on future releases, for that, you should contact your Regional Sales Manager. If you do not have the contact details for your RSM, you can send me a private message with your location, and I will provide it to you.

As mentioned earlier in the case, it should work fine if you build from the command line, but we have not done much, if any, testing with C++.

Best regards, and sorry for the ,

Didrik

I too would like to use C++ (it is 2020 after all!). I've set up a test project and on the command line and the support in Zephyr seems remarkably good. You've got C++17 standard compiler, streams, lambdas, containers, string etc. My test binary even runs ok on the nrf9160DK :)

However, the support for C++ in SES is woeful (despite having a ++ symbol on the icon!). SES just does not recognize cpp files at all and won't even build a project properly that's configured on the command line. Will the Nordic SES version support C++ properly at some point?

Regards,

Paul

Hi, and sorry for the slow response.

We do not have official C++ support in any of our SDKs, so you are mostly on your own here.

Best regards,

Didrik

Command line works, thank you.

do you know what is the problem of SES with C++? Command line build is not so convenient for us.

I just tried myself, and it does indeed look like SES has some problems with C++.

However, the attached project worked fine when building from the command line.

devzone.nordicsemi.com/.../hello_5F00_world_5F00_cpp.zip

Note that I had to disable (or rather, not set) CONFIG_LIB_CPLUSPLUS to make it compile.

Thanks Didrik,

I added CONFIG_CPLUSPLUS=y and CONFIG_LIB_CPLUSPLUS=y in prj.conf

built it on Window SES. Project can be built but just not compile the .cpp file which is in CMakeLists.

what I tested is to use "hello world" in zephyr\samples\hello_world:

changed src/main.c to src/main.cpp, also in CMakeLists

added CONFIG_CPLUSPLUS=y and CONFIG_LIB_CPLUSPLUS=y in prj.conf

Loaded project into SES, and the main.cpp is not in Project 'app/libapp.a' list, but main.c was there before modification:

build and run on nRF9160 DK board won't print "hello world" on terminal as main.c build does.

Did I miss something?

Thanks

Hi.

Did you enable C++ support using CONFIG_CPLUSPLUS and CONFIG_LIB_CPLUSPLUS?

Have you tried building from the command line (you will have to set two environment variables first: ZEPHYR_TOOLCHAIN_VARIANT=gnuarmemb and GNUARMEMB_TOOLCHAIN_PATH=<path to your toolchain install directory>)?

While C++ should be supported in NCS, I do not believe it is much tested, so you are largely on your own.

Best regards,

Didrik
