* guix/ui.scm (define-diagnostic): Use `free-identifier=?' to compare
the user's input with `_' and `N-". This should fix builds with Guile 2.1.
Reported by Cojocaru Alexandru <xojoc@gmx.com>.
This fixes a circular dependency introduced in commit acc26ff ("gnu: Add
pytz.").
* guix/build-system/python.scm (default-python): New procedure.
(python-build): Use it.
Suggested by Andreas Enge <andreas@enge.fr>.
* guix/scripts/substitute-binary.scm (with-networking): New macro.
(guix-substitute-binary): Wrap the body in `with-networking'.
* guix/packages.scm (&package-cross-build-system-error): New condition type.
(package-cross-derivation): Raise &package-cross-build-system-error
when the build system doesn't support cross builds.
* guix/ui.scm (call-with-error-handling): Add
package-cross-build-system-error? case.
* tests/packages.scm ("package-cross-derivation, no cross builder"): New test.
This fixes resolution of DT_NEEDED entries in cross-built libraries.
For instance, if ltdl.so needs libdl.so and has it in its RUNPATH, then
libdl.so is searched for in the right place.
* gnu/packages/cross-base.scm (cross-binutils): Pass
`--with-sysroot=/no-such-path'.
* gnu/packages/guile.scm (guile-2.0): Add Bash as an input
when (%current-target-system) is true. Use %standard-cross-phases as
a basis when (%current-target-system) is true.
* gnu/packages/ncurses.scm (ncurses): Add `cross-pre-install-phase'.
Use different phases when (%current-target-system) is true.
* gnu/packages/readline.scm (readline): Use %standard-cross-phases as
the base when (%current-target-system) is true.
* gnu/packages/libffi.scm (libffi): Use %standard-cross-phases as the
base when cross-compiling. Add (guix build gnu-cross-build) to the
#:modules when cross-compiling. Improve synopsis.
* gnu/packages/gawk.scm (gawk)[arguments]: Use `set-shell-file-name'
phase that works when cross-compiling; use `%standard-cross-phases' as
the base when (%current-target-system) is true.
* gnu/packages/base.scm (coreutils): Remove Perl input
when (%current-target-system) is true. Use %standard-cross-phases as
the base when (%current-target-system) is true.
* guix/build-system/trivial.scm (guile-for-build): New procedure.
(trivial-build): Use it.
(trivial-cross-build): New procedure.
(trivial-build-system): Use it.
* guix/scripts/package.scm (guix-package)[ensure-default-profile]: Check
whether S is true before checking its owner. Fixes the case where we
built %PROFILE-DIRECTORY just above.
* guix/build-system/gnu.scm (inputs-search-paths): New procedure.
(standard-search-paths): Use it.
(expand-inputs): New procedure.
(standard-inputs): Use it.
(standard-cross-packages, standard-cross-inputs,
standard-cross-search-paths, gnu-cross-build): New procedures.
(gnu-build-system): Set `cross-build' field to `gnu-cross-build'.
* gnu/packages/cross-base.scm: Export `cross-gcc', `cross-binutils', and
`cross-libc'.
* guix/build/gnu-cross-build.scm: New file.
* Makefile.am (MODULES): Add it.
* gnu/packages/patches/gcc-cross-environment-variables.patch: Add two
hunks, most notably one that changes GCC to honor LIBRARY_PATH_ENV
when cross-compiling.
* guix/packages.scm (expand-input): New procedure, moved out of...
(package-derivation): ... here. Adjust accordingly.
(package-cross-derivation): Add `cross-system' and `system'
parameters.
