This breaks the compiler's built-in search +path. I've included two patches. The first works on the configure.in file, which +requires your autoconf stuff to test and I'm not ready to meddle with at the +moment. The other works directly on the configure file. I've tested the second +one; it should mirror what the first patch tries to achieve and works for me. + +--- a/configure ++++ b/configure +@@ -2938,10 +2938,6 @@ + echo "$as_me:2938: checking if $CXX works" >&5 + echo $ECHO_N "checking if $CXX works... $ECHO_C" >&6 + +- save_CPPFLAGS="$CPPFLAGS" +- eval cf_includedir=${includedir} +- CPPFLAGS="$CPPFLAGS -I${cf_includedir}" +- + cat >conftest.$ac_ext <<_ACEOF + #line 2946 "configure" + #include "confdefs.h" +@@ -2978,7 +2974,6 @@ + cf_cxx_works=no + fi + rm -f conftest.$ac_objext conftest.$ac_ext +- CPPFLAGS="$save_CPPFLAGS" + + echo "$as_me:2983: result: $cf_cxx_works" >&5 + echo "${ECHO_T}$cf_cxx_works" >&6 diff --git a/sys-libs/ncurses/ncurses-6.0-r1.ebuild b/sys-libs/ncurses/ncurses-6.0-r1.ebuild index ccdd8a5..e173592 100644 --- a/sys-libs/ncurses/ncurses-6.0-r1.ebuild +++ b/sys-libs/ncurses/ncurses-6.0-r1.ebuild @@ -37,6 +37,7 @@ PATCHES=( "${FILESDIR}/${PN}-6.0-pkg-config.patch" "${FILESDIR}/${PN}-5.9-gcc-5.patch" #545114 "${FILESDIR}/${PN}-6.0-ticlib.patch" #557360 + "${FILESDIR}/${PN}-6.0-cppflags-cross.patch" #601426 ) src_prepare() {
