Hi Nelson, (Please keep the bug Cc’d.)

Please remove everything but ‘gcc-toolchain’. Now, if you want to have Objective-C support, you of course have to install ‘gcc-objc’ and/or ‘gcc-objc++’. However, you’ll have to make sure that they come after ‘gcc-toolchain’ in your profile, like so: guix install gcc-toolchain gcc-objc > Maybe it is related to another problem that I wanted to eventually > raise on a guix list.

The GNU build system purposefully makes no assumptions on the location of tools: ‘configure.ac’ files have AC_PROG_SED, AC_PATH_PROG, and similar calls. > On your GUIX systems, do you have a reasonably populated /bin? Ditto > the other three. No. By default, one gets /bin/sh, and nothing more. This is a radical departure from Unix tradition, but (1) GNU’s Not Unix ;-), and (2) the lack of a global name space gives rise to many interesting properties: transactional upgrades and rollbacks are now possible, per-user profiles, on-the-fly environments with ‘guix environment’, etc. > (packages > (list (specification->package "nss-certs"))) Note that this is bogus, due to <https://issues.guix.gnu.org/issue/35541>, which will be fixed in Guix 1.0.1 in the coming days. You should write: (packages (append (list (specification->package "nss-certs")) %base-packages)) to get the full set of “base packages” (Coreutils, grep, etc.) in $PATH by default. Once you’ve made that change, you have to reconfigure your system: guix system reconfigure /etc/config.scm HTH! Thanks, Ludo’.
