Bond >Release: FreeBSD 4.3-BETA i386 >Organization: None >Environment: >Description: bsd.prog.mk from /usr/share/mk/ doesn't properly link programs with C++ source files against -lstdc++ as it should. The majority of C++ programs hence fail to build. >How-To-Repeat: Construct a Makefile in the standard bsd.prog.mk format and include C++ files in the $SRCS variable (.cc, .C, .cxx, etc.). Be sure to use a piece of the C++ standard library in your code (e.g., iostreams). >Fix: --- /usr/src/share/mk/bsd.prog.mk.orig Wed Mar 21 22:30:10 2001 +++ /usr/src/share/mk/bsd.prog.mk Wed Mar 21 23:18:52 2001 @@ -27,10 +27,14 @@ .if defined(PROG) .if defined(SRCS) -# If there are Objective C sources, link with Objective C libraries. +# If there are Objective C or C++ sources, link with appropriate libraries. .if ${SRCS:M*.m} != "" OBJCLIBS?= -lobjc LDADD+= ${OBJCLIBS} +.endif +.if ${SRCS:C/\.(cc\$|C\$|cxx\$|cpp\$)//} != ${SRCS} +CXXLIBS?= -lstdc++ +LDADD+= ${CXXLIBS} .endif OBJS+= ${SRCS:N*.h:R:S/$/.o/g} >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
