This project of mine was to build an ISO for an old Thinkpad that would act as a reciever from https://github.com/badaix/snapcast, but I couldn't find anything useful on this libarchive error. "libarchive-dev" is installed on the host using "apt install". You guys probably know how to recreate this, but the host is just a Debian netinst, no DE, and then git installed. Installed dependencies as of https://medium.com/@hungryspider/building-custom-linux-for-raspberry-pi-using-buildroot-f81efc7aa817, cloned the Buildroot repo from Github, " make pc_x86_64_bios_defconfig", and then replaced the .config file generated by the one I used the first time (was sanity/dependancy checking). Ran make, which ran for about a good 30-45 mins until it stopped and I saw the libarchive error.

From host/x86_64-buildroot-linux-gnu/sysroot/usr/lib/pkgconfig/libarchive.pc:

	[...]
	Requires.private: iconv libssl libcrypto


From build/libarchive-3.6.2/configure.ac:

	AC_ARG_WITH([iconv],
	  AS_HELP_STRING([--without-iconv], [Don't try to link against iconv]))


And with the following local buildroot patch:

diff --git a/package/libarchive/libarchive.mk b/package/libarchive/libarchive.mk
index cfc148d01d..02cca9cee9 100644
--- a/package/libarchive/libarchive.mk
+++ b/package/libarchive/libarchive.mk
@@ -70,7 +70,7 @@ endif
 ifeq ($(BR2_PACKAGE_LIBICONV),y)
 LIBARCHIVE_DEPENDENCIES += libiconv
 else
-LIBARCHIVE_CONF_OPTS += --without-libiconv-prefix
+LIBARCHIVE_CONF_OPTS += --without-libiconv-prefix --without-iconv
 endif
 
 ifeq ($(BR2_PACKAGE_LIBXML2),y)


The opkg package builds without errors (after re-build of the libarchive package)...

Regards,
Peter
