It fixes following output: ``` HOSTCC tools/kwboot tools/kwboot.c: In function 'kwboot_tty_change_baudrate': tools/kwboot.c:662:6: error: 'struct termios' has no member named 'c_ospeed' 662 | tio.c_ospeed = tio.c_ispeed = baudrate; | ^ tools/kwboot.c:662:21: error: 'struct termios' has no member named 'c_ispeed' 662 | tio.c_ospeed = tio.c_ispeed = baudrate; | ^ tools/kwboot.c:690:31: error: 'struct termios' has no member named 'c_ospeed' 690 | if (!_is_within_tolerance(tio.c_ospeed, baudrate, 3)) | ^ tools/kwboot.c:693:31: error: 'struct termios' has no member named 'c_ispeed' 693 | if (!_is_within_tolerance(tio.c_ispeed, baudrate, 3)) | ``` Tested-by: Michal Vasilek Signed-off-by: Josef Schlehofer --- diff --git a/package/boot/uboot-mvebu/patches/0001-tools-termios_linux.h-Fix-compilation-on-non-glibc-s.patch b/package/boot/uboot-mvebu/patches/0001-tools-termios_linux.h-Fix-compilation-on-non-glibc-s.patch new file mode 100644 index 0000000000..e2f8a08bea --- /dev/null +++ b/package/boot/uboot-mvebu/patches/0001-tools-termios_linux.h-Fix-compilation-on-non-glibc-s.patch @@ -0,0 +1,44 @@ +From 82a6da13c3a113eefdb378ff53635f32a6184d6f Mon Sep 17 00:00:00 2001 +From: =?UTF-8?q?Pali=20Roh=C3=A1r?= +Date: Thu, 8 Sep 2022 16:59:36 +0200 +Subject: [PATCH] tools: termios_linux.h: Fix compilation on non-glibc systems +MIME-Version: 1.0 +Content-Type: text/plain; charset=UTF-8 +Content-Transfer-Encoding: 8bit + +TCGETS2 is defined in header file asm/ioctls.h provided by linux kernel. +On glib systems it is automatically included by some other glibc include +header file and therefore TCGETS2 is present in termios_linux.h when +linux kernel provides it. + +On non-glibc systems (e.g. musl) asm/ioctls.h is not automatically included +which results in the strange error that BOTHER is supported, TCGETS2 not +defined and struct termios does not provide c_ispeed member. + + tools/kwboot.c: In function 'kwboot_tty_change_baudrate': + tools/kwboot.c:662:6: error: 'struct termios' has no member named 'c_ospeed' + 662 | tio.c_ospeed = tio.c_ispeed = baudrate; + | ^ + +Fix this issue by explicitly including asm/ioctls.h file which provides +TCGETS2 macro (if supported on selected architecture) to not depending on +glibc auto-include behavior and because termios_linux.h requires it. + +With this change it is possible compile kwboot with musl libc. + +Reported-by: Michal Vasilek +Signed-off-by: Pali Rohár +--- + tools/termios_linux.h | 1 + + 1 file changed, 1 insertion(+) + +--- a/tools/termios_linux.h ++++ b/tools/termios_linux.h +@@ -29,6 +29,7 @@ + #include + #include + #include ++#include + #include + + #if defined(BOTHER) && defined(TCGETS2)
