So, if libical needs TZ info, forcibly enable it (or depend on it). The only gotcha is that we don;t install TZ for musl. However, from the look of it, it should be ready to support tzdata, so our current limitation is probably just incorrect. I'm trying to confirm that. In the meantime, you should select BR2_TARGET_TZ_INFO from the libical Config.in, but only if not musl. And in the .mk, use the suggestion by Baruch. So: Config.in: config BR2_PACKAGE_LIBICAL bool "libical" depends on blabla select BR2_TARGET_TZ_INFO if BR2_TOOLCHAIN_USES_GLIBC || BR2_TOOLCHAIN_USES_UCLIBC libical.mk: ifeq ($(BR2_TARGET_TZ_INFO),) LIBICAL_CONF_OPTS += -DUSE_BUILTIN_TZDATA=true endif Which means that on glibc or uClibc, we'd rely on the system-wide tzdata, but on musl we'd use the bundled one.

Yann has submitted a patch that adds TZ support for musl, and I already merged it. So all what needs to be done is to "select BR2_TARGET_TZ_INFO" in libical. Marc, could you submit such a patch?

A ver recent commit makes this available for all types of toolchains, not just glibc or uClibc. So, your change can now easily be changed to use: config BR2_PACKAGE_LIBICAL bool "libical" depends on exiting-blabla select BR2_TARGET_TZ_INFO > comment "libical needs a toolchain w/ C++, dynamic library, wchar" > depends on !BR2_INSTALL_LIBSTDCPP || !BR2_USE_WCHAR || \ > BR2_STATIC_LIBS > diff --git a/package/libical/libical.mk b/package/libical/libical.mk > index e8cb3f8..a8bcefb 100644 > --- a/package/libical/libical.mk > +++ b/package/libical/libical.mk > @@ -14,4 +14,8 @@ LIBICAL_LICENSE_FILES = LICENSE > # Gentoo/alpinelinux as well > LIBICAL_CONF_OPTS = -DSHARED_ONLY=true > > +ifeq ($(BR2_PACKAGE_LIBICAL_BUILTIN_TZDATA),y) > +LIBICAL_CONF_OPTS += -DUSE_BUILTIN_TZDATA=true > +endif And of course you can now drop this change, although I would still keep it as: LIBICAL_CONF_OPTS += -DUSE_BUILTIN_TZDATA=OFF to be sure it does not get used.
