Hi! I ran into this compilation error while compiling flatpak-builder with --prefer-static (the key point is the missing symbols atthe end of the log - please just skim):

It seems to me that libelf.a has unresolved dependencies. I see that these symbols are defined in 'lib/libeu.a' but that does not get installed nor is it referenced in the .pc file for neither libdw nor libelf. I am not experienced with the package so this might be a simple mistake on my side. However, using static compilation seems to be controversial to most distros today (even LFS, which I am basing my distro on), and I suspect that I might just have run into an issue that nobody has seen because it is such an unusual usecase. Perhaps. 🙂 Anyways, any input would be appreciated! Kind regards, Henrik Holst
