Makefile.gnuhost revision 1.17
1# $NetBSD: Makefile.gnuhost,v 1.17 2003/02/07 01:52:51 lukem Exp $ 2# 3# Rules used when building a GNU host package. Expects MODULE to be set. 4# 5# There's not a lot we can do to build reliably in the face of many 6# available configuration options. To be as low-overhead as possible, 7# we follow the following scheme: 8# 9# * Configuration is only re-run when an autoconf source file (such as 10# "configure" or "config.sub") is changed. 11# 12# * "config.status" is run to rebuild Makefiles and .h files if an 13# autoconf-parsed file (such as Makefile.in) is changed. 14# 15# * If UPDATE is set, "make install" is only run if a build has happened 16# since the last install in the current directory. 17 18.include <bsd.own.mk> 19 20GNUHOSTDIST?= ${.CURDIR}/../../gnu/dist/${MODULE} 21 22FIND_ARGS+= \! \( -type d \( \ 23 -name 'CVS' -o \ 24 -name 'config' -o \ 25 -name 'doc' -o \ 26 -name 'po' -o \ 27 -name 'nbsd.mt' -o \ 28 -name 'tests*' \ 29 \) -prune \) 30 31# Do this "find" only if actually building something. 32.if (${USETOOLS} == "yes") && empty(.MAKEFLAGS:M-V*) && \ 33 (make(all) || make(realall) || (!make(clean) && !make(cleandir) && !make(obj))) && \ 34 !defined(_GNU_CFGSRC) 35 36_GNU_CFGSRC!= find ${GNUHOSTDIST} ${FIND_ARGS} \ 37 -type f \( -name 'config*' -o -name '*.in' \) -print 38.MAKEOVERRIDES+= _GNU_CFGSRC 39.endif 40 41CONFIGURE_ENV+= CC=${HOST_CC:Q} \ 42 CFLAGS=${HOST_CFLAGS:Q} \ 43 CPPFLAGS=${HOST_CPPFLAGS:Q} \ 44 CXX=${HOST_CXX:Q} \ 45 CXXFLAGS=${HOST_CXXFLAGS:Q} \ 46 INSTALL=${HOST_INSTALL_FILE:Q} \ 47 LDFLAGS=${HOST_LDFLAGS:Q} \ 48 LEX=${LEX:Q} \ 49 PATH="${TOOLDIR}/bin:$$PATH" \ 50 YACC=${YACC:Q} 51 52CONFIGURE_ARGS+=--prefix=${TOOLDIR} --disable-shared 53 54.ifndef _NOWRAPPER 55MAKE_ARGS:= -f ${.PARSEDIR}/Makefile.gnuwrap ${MAKE_ARGS} 56.else 57MAKE_ARGS+= _NOWRAPPER=1 58.endif 59 60MAKE_ARGS+= BISON=true DESTDIR= INSTALL=${HOST_INSTALL_FILE:Q} 61 62ALL_TARGET?= all 63INSTALL_TARGET?=install 64 65.configure_done: ${_GNU_CFGSRC} ${.CURDIR}/Makefile 66 @mkdir build 2>/dev/null || true 67 @(cd build && ${CONFIGURE_ENV} sh ${GNUHOSTDIST}/configure ${CONFIGURE_ARGS}) 68 @touch $@ 69 70# The .build_done timestamp is only updated if a file actually changes 71# in the build tree during "make all".
