Makefile.gnuhost revision 1.58
1 # $NetBSD: Makefile.gnuhost,v 1.58 2026/10/10 01:41:05 tls 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 MKUPDATE != "no", "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 20 # Disable use of pre-compiled headers on Darwin. 21 BUILD_OSTYPE!= uname -s 22 HOST_COMPILER_CLANG!= if ${HOST_CC} --version | grep -q -s clang; then echo yes; else echo no; fi 23 .if ${HOST_COMPILER_CLANG} == "yes" 24 HOST_CFLAGS+=-O2 -no-cpp-precomp 25 .endif 26 27 # Allow selection of Xcode target OS version 28 .if ${BUILD_OSTYPE} == "Darwin" && defined(SDKROOT) 29 CONFIGURE_ENV+= SDKROOT=${SDKROOT:Q} 30 .endif 31 32 MAKE_PROGRAM?= ${MAKE} 33 34 .for i in 3 2 35 .if exists(${.CURDIR}/../../external/gpl${i}/${MODULE}/dist) 36 GNUHOSTDIST?= ${.CURDIR}/../../external/gpl${i}/${MODULE}/dist 37 .endif 38 .endfor 39 40 FIND_ARGS+= \! \( -type d \( \ 41 -name 'CVS' -o \ 42 -name 'config' -o \ 43 -name 'doc' -o \ 44 -name 'po' -o \ 45 -name 'nbsd.mt' -o \ 46 -name 'tests*' \ 47 \) -prune \) 48 49 # Do this "find" only if actually building something. 50 .if (${USETOOLS} == "yes") && empty(.MAKEFLAGS:M-V*) && \ 51 (make(all) || make(realall) || (!make(clean) && !make(cleandir) && !make(obj))) && \ 52 !defined(_GNU_CFGSRC) 53 54 _GNU_CFGSRC!= find ${GNUHOSTDIST} ${FIND_ARGS} \ 55 -type f \( -name 'config*' -o -name '*.in' \) -print 56 .MAKEOVERRIDES+= _GNU_CFGSRC 57 .endif 58 59 CONFIGURE_ENV+= \ 60 AR=${HOST_AR:Q} \ 61 AWK=${TOOL_AWK:Q} \ 62 CC=${HOST_CC:Q} \ 63 CFLAGS=${HOST_CFLAGS:Q} \ 64 CONFIG_SHELL=${HOST_SH:Q} \ 65 CPPFLAGS=${HOST_CPPFLAGS:Q} \ 66 CXX=${HOST_CXX:Q} \ 67 CXXFLAGS=${HOST_CXXFLAGS:Q} \ 68 INSTALL=${HOST_INSTALL_FILE:Q} \ 69 LDFLAGS=${HOST_LDFLAGS:Q} \ 70 LEX=${LEX:Q} \ 71 FLEX=${LEX:Q} \ 72 M4=${TOOL_M4:Q} \ 73 MAKE=${MAKE_PROGRAM:Q} \ 74 PATH="${TOOLDIR}/bin:$$PATH" \ 75 RANLIB=${HOST_RANLIB:Q} \ 76 YACC=${YACC:Q} 77 78 BUILD_ENV+= ${CONFIGURE_ENV} 79 80 CONFIGURE_ARGS+=--prefix=${TOOLDIR} 81 .if ${MKPIC} == "no" 82 CONFIGURE_ARGS+=--disable-shared 83 .endif 84 85 .if ${MAKEVERBOSE} == 0 86 CONFIGURE_ARGS+=--silent 87 .endif 88 89 90 .if ${MAKE_PROGRAM} == ${MAKE} 91 .ifndef _NOWRAPPER 92 # Some systems have a small ARG_MAX.
