Let's see if we can include the attachment this time, yes? --ado -----Original Message----- From: John Faith [mailto:jfaith@freescale.com] Sent: Thursday, January 11, 2007 1:39 PM To: tz@lecserver.nci.nih.gov Subject: Cross building tzcode Hello, In the hope that this might be useful to someone else, attached is a patch to the main tzcode Makefile that we use to cross build. The reason for the patch is that in a cross-compiling environment, generating the data files requires a zic which runs on the host and the target requires the cross-built binary, so the Makefile generates both. I have tested this with ARM targets. We build using a rpm .spec file with something like: make HOST_CC=<path_to_the_host_cc> TOPDIR=%{__prefix} TZDIR=%{_prefix}/share/zoneinfo ETCDIR=%{_prefix}/usr/bin By the way, you can probably ignore the parts about "nawk"->"awk" (I did not have nawk installed), and the bit about "ksh"->"bash" (I didn't have ksh). Thanks! , John Faith Freescale Semiconductor --- timezone-2006n/Makefile.orig 2006-10-02 12:32:16.000000000 -0700 +++ timezone-2006n/Makefile 2006-10-19 10:25:23.000000000 -0700 @@ -218,9 +218,11 @@ CFLAGS= zic= ./zic ZIC= $(zic) $(ZFLAGS) +zic-host= ./zic-host +ZIC-HOST= $(zic-host) $(ZFLAGS) # The name of a Posix-compliant `awk' on your system. -AWK= nawk +AWK= awk # The path where SGML DTDs are kept.
