From: Max Reitz Date: Mon, 27 May 2019 14:25:40 +0000 (+0200) Subject: ui/curses: Fix build with -m32 X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=dc3c871ae0f06030cfd713e44fcf79a4705553d1;p=qemu.git ui/curses: Fix build with -m32 wchar_t may resolve to be an unsigned long on 32-bit architectures. Using the %x conversion specifier will then give a compiler warning: ui/curses.c: In function ‘get_ucs’: ui/curses.c:492:49: error: format ‘%x’ expects argument of type ‘unsigned int’, but argument 3 has type ‘wchar_t’ {aka ‘long int’} [-Werror=format=] 492 | fprintf(stderr, "Could not convert 0x%04x " | ~~~^ | | | unsigned int | %04lx 493 | "from wchar_t to a multibyte character: %s\n", 494 | wch, strerror(errno)); | ~~~ | | | wchar_t {aka long int} ui/curses.c:504:49: error: format ‘%x’ expects argument of type ‘unsigned int’, but argument 3 has type ‘wchar_t’ {aka ‘long int’} [-Werror=format=] 504 | fprintf(stderr, "Could not convert 0x%04x " | ~~~^ | | | unsigned int | %04lx 505 | "from a multibyte character to UCS-2 : %s\n", 506 | wch, strerror(errno)); | ~~~ | | | wchar_t {aka long int} Fix this by casting the wchar_t value to an unsigned long and using %lx as the conversion specifier.
