Compiling for Radiomaster TX16s

[wilopaan]

Hi all,

something changed in the last days. I was able to compile the firmware for tx16s the last weeks, but some days ago it started producing the following error:

Any hints?

[wilopaan]

Just a side note: compiling for the T12 or x9e is ok with the same tools (compiler version , ...).

[wilopaan]

No help?
I just got my tx16s and I am very eager to build a new OpenTx for it.

[jtaylor]

I am getting no errors compiling on openSUSE LEAP 15.2. I don't have the transmitter so don't know if the firmware works, but it compiles clean. Are you using the recommended version of gcc-arm-none-eabi? People seem to have problems if they don't use the recommended version. I think it's gcc-arm-none-eabi-4_7-2013q3-20130916, I'm not at my Linux system at the moment so can't check but I think that's what I'm using.

I got it working.

There is a incompatibility in core_cm4.h. There is an anonymous typedef. After fixing that, it compiles fine.

[Kilrah]

I wouldn't have an idea apart from using the wrong compiler version, the one mentioned in the instructions must be used for firmware you intend to fly with.

Also you never give data about your problem so it's not easy to help you, we don't even know what OS you're compiling on.

Maybe it is an issue with the host-compiler? This is a gcc from trunk:

Compiled again this morning using your cmake options (openSUSE Leap 15.1) with no errors. Pasted my cmake output and versions below in case you want to compare. One big difference is I'm using gcc 7.5.0

Thank you.

Yes, seems the error is introduced due my very new compiler: something change in C/C++ that typedef unnamed structs must have a tag name.

Maybe the CMSIS (thridparty) is outdated?
