From 9a3a1a806f0c6963c671f0a46f6e910c6206e681 Mon Sep 17 00:00:00 2001 From: Christian Eggers Date: Wed, 16 Feb 2022 12:08:33 +0100 Subject: [PATCH] mc: fix build if ncurses have been configured without wide characters Some distros like poky-tiny set ENABLE_WIDEC=false, which disables wide character support for ncurses. The new patch fixes the build of mc for this case. Since 9000f8033662, NCURSES_WIDECHAR is set explicitly to 1 for musl. This doesn't work for ENABLE_WIDEC==false. In this case, NCURSES_WIDECHAR must be set explicitly to 0, as curses.h does not record whether the ncurses library has actually been built with or without wide characters. Fixes: 9000f8033662 ("mc: upgrade 4.8.25 -> 4.8.26") Signed-off-by: Christian Eggers Signed-off-by: Richard Purdie Signed-off-by: Anuj Mittal --- ...FTBFS-with-ncurses-build-with-disabl.patch | 87 +++++++++++++++++++ meta/recipes-extended/mc/mc_4.8.27.bb | 5 +- 2 files changed, 91 insertions(+), 1 deletion(-) create mode 100644 meta/recipes-extended/mc/files/0001-Ticket-4200-fix-FTBFS-with-ncurses-build-with-disabl.patch diff --git a/meta/recipes-extended/mc/files/0001-Ticket-4200-fix-FTBFS-with-ncurses-build-with-disabl.patch b/meta/recipes-extended/mc/files/0001-Ticket-4200-fix-FTBFS-with-ncurses-build-with-disabl.patch new file mode 100644 index 0000000000..408473664f --- /dev/null +++ b/meta/recipes-extended/mc/files/0001-Ticket-4200-fix-FTBFS-with-ncurses-build-with-disabl.patch @@ -0,0 +1,87 @@ +From e7bbf72544ab62db9c92bfe7bd1155227e78c621 Mon Sep 17 00:00:00 2001 +From: Andrew Borodin +Date: Sat, 28 Aug 2021 11:46:53 +0300 +Subject: [PATCH] Ticket #4200: fix FTBFS with ncurses build with + --disable-widec. + +Upstream-Status: Accepted [https://github.com/MidnightCommander/mc/commit/e7bbf72544] +Signed-off-by: Andrew Borodin +--- + lib/tty/tty-ncurses.c | 8 ++++++++ + lib/tty/tty-ncurses.h | 5 +++++ + lib/tty/tty-slang.h | 2 ++ + src/filemanager/boxes.c | 2 ++ + 4 files changed, 17 insertions(+) + +diff --git a/lib/tty/tty-ncurses.c b/lib/tty/tty-ncurses.c +index f619c0a7bf31..13058a624208 100644 +--- a/lib/tty/tty-ncurses.c ++++ b/lib/tty/tty-ncurses.c +@@ -560,6 +560,7 @@ tty_fill_region (int y, int x, int rows, int cols, unsigned char ch) + void + tty_colorize_area (int y, int x, int rows, int cols, int color) + { ++#ifdef ENABLE_SHADOWS + cchar_t *ctext; + wchar_t wch[10]; /* TODO not sure if the length is correct */ + attr_t attrs; +@@ -585,6 +586,13 @@ tty_colorize_area (int y, int x, int rows, int cols, int color) + } + + g_free (ctext); ++#else ++ (void) y; ++ (void) x; ++ (void) rows; ++ (void) cols; ++ (void) color; ++#endif /* ENABLE_SHADOWS */ + } + + /* --------------------------------------------------------------------------------------------- */ +diff --git a/lib/tty/tty-ncurses.h b/lib/tty/tty-ncurses.h +index d75df9533ab9..8feb17ccd045 100644 +--- a/lib/tty/tty-ncurses.h ++++ b/lib/tty/tty-ncurses.h +@@ -30,6 +30,11 @@ + #define NCURSES_CONST const + #endif + ++/* do not draw shadows if NCurses is built with --disable-widec */ ++#if defined(NCURSES_WIDECHAR) && NCURSES_WIDECHAR ++#define ENABLE_SHADOWS 1 ++#endif ++ + /*** typedefs(not structures) and defined constants **********************************************/ + + /*** enums ***************************************************************************************/ +diff --git a/lib/tty/tty-slang.h b/lib/tty/tty-slang.h +index 5b12c6512853..eeaade388af4 100644 +--- a/lib/tty/tty-slang.h ++++ b/lib/tty/tty-slang.h +@@ -23,6 +23,8 @@ + #define COLS SLtt_Screen_Cols + #define LINES SLtt_Screen_Rows + ++#define ENABLE_SHADOWS 1 ++ + /*** enums ***************************************************************************************/ + + enum +diff --git a/src/filemanager/boxes.c b/src/filemanager/boxes.c +index 3eb525be4a9b..98df5ff2ed9a 100644 +--- a/src/filemanager/boxes.c ++++ b/src/filemanager/boxes.c +@@ -280,7 +280,9 @@ appearance_box_callback (Widget * w, Widget * sender, widget_msg_t msg, int parm + switch (msg) + { + case MSG_INIT: ++#ifdef ENABLE_SHADOWS + if (!tty_use_colors ()) ++#endif + { + Widget *shadow; + +-- +2.34.1 + diff --git a/meta/recipes-extended/mc/mc_4.8.27.bb b/meta/recipes-extended/mc/mc_4.8.27.bb index 546e615d1d..e877780ea0 100644 --- a/meta/recipes-extended/mc/mc_4.8.27.bb +++ b/meta/recipes-extended/mc/mc_4.8.27.bb @@ -11,6 +11,7 @@ RRECOMMENDS:${PN} = "ncurses-terminfo" SRC_URI = "http://www.midnight-commander.org/downloads/${BPN}-${PV}.tar.bz2 \ file://0001-mc-replace-perl-w-with-use-warnings.patch \ file://nomandate.patch \ + file://0001-Ticket-4200-fix-FTBFS-with-ncurses-build-with-disabl.patch \ " SRC_URI[sha256sum] = "2f52dd9c75c20d8eac7701bd3a8c6c125aaf8cdd9cf12b78ca50a0102b543407" @@ -27,7 +28,9 @@ PACKAGECONFIG ??= "" PACKAGECONFIG[smb] = "--enable-vfs-smb,--disable-vfs-smb,samba," PACKAGECONFIG[sftp] = "--enable-vfs-sftp,--disable-vfs-sftp,libssh2," -CFLAGS:append:libc-musl = ' -DNCURSES_WIDECHAR=1 ' +# enable NCURSES_WIDECHAR=1 only if ENABLE_WIDEC has not been explicitly disabled (e.g. by the distro config). +# When compiling against the ncurses library, NCURSES_WIDECHAR needs to explicitly set to 0 in this case. +CFLAGS:append:libc-musl = "${@' -DNCURSES_WIDECHAR=1' if bb.utils.to_boolean((d.getVar('ENABLE_WIDEC') or 'True')) else ' -DNCURSES_WIDECHAR=0'}" EXTRA_OECONF = "--with-screen=ncurses --without-gpm-mouse --without-x --disable-configure-args" EXTRANATIVEPATH += "file-native" -- 2.40.1
