Issues Compiling WFServer on Raspberry Pi Bullseye

Installation Help
1

Hi,

Thanks for all of the recent updates. Great work.

I had a go at compiling WFServer on a Raspberry Pi running Bulleye.

Initially I had an issue with getpid, fork, setsid, gettablesize, close and dup not being declared in main.cpp. I was able to resolve this by adding #include <unistd.h>.

I’m now getting errors
…/wfview/rigctld.cpp:1376:38: error: ‘as_const’ is not a member of ‘std’; did you mean ‘is_const’?
1376 | for (const bandType &band : std::as_const(rigCaps->bands))

Any assistance would be appreciated.

I’m using the build instructions from here
https://wfview.org/wfview-user-manual/headless-server/

I’m trying to compile V2.03.

Hi Mike,

What compiler and compiler flags are you using?

as_const was introduced in C++17 so this suggests you have an old compiler. Maybe time to upgrade?

As it happens, that file isn’t actually used by wfserver anyway, so I have removed it from the build.

If you pull the updated master branch, it should now compile.

Thanks Phil,

That has fixed it. I will look at upgrading to Bookworm when I get some time and will recompile with the updated compiler. For now it is working well.

Had a quick DX contact to Spain on 20M.

Thanks for your help.
