There is an upstream fix[1], but backporting it is not straight forward. /scratch/union/staging_dir/toolchain-x86_64_gcc-15.1.0_glibc/x86_64-openwrt-linux-gnu/include/c++/15.1.0/cstddef:81:21: error: redefinition of 'struct std::__byte_operand' 81 | template<> struct __byte_operand { using __type = byte; }; | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /scratch/union/staging_dir/toolchain-x86_64_gcc-15.1.0_glibc/x86_64-openwrt-linux-gnu/include/c++/15.1.0/cstddef:78:21: note: previous definition of 'struct std::__byte_operand' 78 | template<> struct __byte_operand { using __type = byte; }; | ^~~~~~~~~~~~~~~~~~~~ make[4]: *** [Makefile:438: ../obj_s/cursesp.o] Error 1 1. https://ncurses.scripts.mit.edu/?p=ncurses.git;a=commit;h=394a1a6cf317912584592e33184ef550e738a4b9 Signed-off-by: John Audia Link: https://github.com/openwrt/openwrt/pull/19335 Signed-off-by: Robert Marko --- diff --git a/package/libs/ncurses/Makefile b/package/libs/ncurses/Makefile index 0fcc3888401..b6b9a4eb896 100644 --- a/package/libs/ncurses/Makefile +++ b/package/libs/ncurses/Makefile @@ -10,7 +10,7 @@ include $(TOPDIR)/rules.mk PKG_NAME:=ncurses PKG_CPE_ID:=cpe:/a:gnu:ncurses PKG_VERSION:=6.4 -PKG_RELEASE:=2 +PKG_RELEASE:=3 PKG_SOURCE:=$(PKG_NAME)-$(PKG_VERSION).tar.gz PKG_SOURCE_URL:=@GNU/$(PKG_NAME) @@ -52,7 +52,7 @@ define Package/libncurses-dev TITLE:=Development files for the ncurses library endef -TARGET_CFLAGS += $(FPIC) +TARGET_CFLAGS += $(FPIC) -std=gnu17 CONFIGURE_ARGS += \ --enable-echo \
