The question "What packages do I need to do normal C development?" should really be documented. How about a doc section - at the beginning of the chapter https://guix.gnu.org/manual/en/html_node/Development.html - that says: Packages needed for C development =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D For C development, you will typically need the packages make gcc-toolchain gdb Do NOT install glibc and binutils explicitly, as they would shadow the 'ld' wrapper that is necessary for proper operation of GCC. Additionally, the documentation page https://guix.gnu.org/manual/en/html_node/Application-Setup.html starts with the sentence "When using Guix on top of GNU/Linux distribution other than Guix System = =2E.." but then the majority of the page applies to native Guix as well. How about restructuring this documentation chapter into two pages: - one that explains things valid about Guix in general, - one that covers only the foreign-distro topics. > Another way to do software development is with =E2=80=98guix environment= =E2=80=99: >=20 > https://guix.gnu.org/manual/en/html_node/Development.html >=20 > For example, if you want to hack on Gettext, run: >=20 > guix environment gettext >=20 > That spawns a shell containing all the development tools and environment > variables to hack on gettext. Sounds very interesting. But for the moment, I use guix only as a test platform. Bruno
