When trying to build gtk+ I get: /tmp/guix-build-libsoup-2.70.0.drv-0 --- stderr --- ** ERROR:../libsoup-2.70.0/tests/ssl-test.c:394:do_tls_interaction_test: Unexpected status 7 Connection terminated unexpectedly (expected 6 SSL handshake failed) ------- Full log written to /tmp/guix-build-libsoup-2.70.0.drv-0/build/meson-logs/testlog.txt FAILED: meson-test /gnu/store/9m03qg3zrcfr3sxmr5592vkaa4p33sci-meson-for-build-0.53.2/bin/meson test --no-rebuild --print-errorlogs ninja: build stopped: subcommand failed. command "ninja" "test" failed with status 1 gtk+ had a problem: TEST: tree-relationships...

The 'hicolor' theme was not found either, perhaps you need to install it. You can get a copy from: http://icon-theme.freedesktop.org/releases FAIL GTester: last random seed: R02S4bb1d91fca6f2b72aa71362d1367bf22 (pid=9372) /a11y/tree/relations: OK FAIL: tree-relationships That's because hicolor-icon-theme was not found. Adding it to native-inputs helped, so I did. Pushed to wip-desktop with slight changes to mend these problems. Would it be possible to remove the dependency on Java? Java is not reproducible right now which makes building gtksourceview (any version) difficult for me.
