Hi, I am playing with boost contexts which is configured out by the current port. I am able to make execution_context and fcontext work on amd64. The first using a simple test program and the second using a non-trival program.
The only actual change in boost itself is to use a mmap(... MMAP_STACK ...) for stack allocation. So I like to enable the disabled parts. They are not extensivly tested and some other parts might need a patch too (there are several classes creating stacks). At the moment I just like to know if I am taking the right approach port-wise. So, any comments or advise? -Otto Index: Makefile =================================================================== RCS file: /cvs/ports/devel/boost/Makefile,v retrieving revision 1.75 diff -u -p -r1.75 Makefile --- Makefile 11 Sep 2018 19:26:14 -0000 1.75 +++ Makefile 21 Nov 2018 12:17:35 -0000 @@ -7,7 +7,7 @@ COMMENT= free peer-reviewed portable C++ VERSION= 1.66.0 DISTNAME= boost_${VERSION:S/./_/g} PKGNAME= boost-${VERSION} -REVISION= 0 +REVISION= 2 CATEGORIES= devel MASTER_SITES= ${MASTER_SITE_SOURCEFORGE:=boost/} EXTRACT_SUFX= .tar.bz2 @@ -45,11 +45,7 @@ BOOST_LIBS= boost_atomic-mt \ boost_unit_test_framework-mt boost_unit_test_framework \ boost_wserialization-mt boost_wserialization \ boost_wave-mt \ - boost_type_erasure-mt boost_type_erasure \ - -.for _lib in ${BOOST_LIBS} -SHARED_LIBS+= ${_lib} ${SO_VERSION} -.endfor + boost_type_erasure-mt boost_type_erasure HOMEPAGE= http://www.boost.org/ @@ -63,6 +59,12 @@ WANTLIB += ${COMPILER_LIBCXX} bz2 c icud COMPILER= base-clang ports-gcc +.if ${MACHINE_ARCH} == "amd64" +PKG_ARGS+=-Damd64=1 +.else +PKG_ARGS+=-Damd64=0 +.endif + MODULES= lang/python MODPY_RUNDEP= No @@ -102,7 +104,24 @@ BOOTSTRAP= --with-bjam=${WRKSRC}/bjam \ # 'context' and 'coroutine' use MD bits and miss support for Alpha, # PA-RISC, SPARC and SuperH.
