Re: Compilation on latest FreeBSD

[Martin Schanzenbach]

I pushed a commit into master for this. It may be that usage of *swap16 
was introduced rather recently (March 2025) and never tested for 
portability.

Hopefully this fixes it for you.

On a whim, maybe this patch works for you?

Hello,


I only occasionally compile on recent OpenBSDs. This error is new to 
me and completely unclear what the problem ist.

in src/include/gnunet_common.h there is an ifdef for FreeBSD that 
defines bswap_XY to bswapXY, which should exist: 
https://man.freebsd.org/cgi/man.cgi?query=bswap16&apropos=0&sektion=9&manpath=FreeBSD+15.0-CURRENT&arch=default&format=html

Now, I do not know if FreeBSD wants any special linker flags for 
those symbols. But that does not seem to be the problem at all, the 
problem seems to be that the bswap_16 symbol is not found, which 
should not really ever happen...


Anyway, maybe you can fiddle around with gnunet_common.h to make it 
compile somehow and provide a patch?


Best

Martin

Dear,

I see that there are not many reactions in general for FreeBSD. 
Maybe I will share what I did:
