Hello, This is not technically a bug with buildroot, but with libiconv in Arch Linux, but the only "workaround" that I found so far has to be done with the "configure" phase of building anything that use libiconv on Arch Linux. I need to pass "--with-libiconv" option to the configure script of uCLib, or any other that use the HOST (Arch Linux, in this case) libiconv, so that the configure can setup the compiler to find it. So, how can I pass this option in buildroot? Thanks.
Leo, I'm also using up-to-date Arch Linux and I don't remember having any specific problem in Buildroot due to it, even when building uClibc toolchains. Can you share a .config (and whether you're using latest master or any specific version) so that I can try to reproduce it?
Bug is one month old, and no detailed information was provided, despite being asked for. Leo, please reopen with more details if you still experience a problem.
