From ffbd8dfb8a1fcbc0cb209f8ede4841c543524525 Mon Sep 17 00:00:00 2001 From: Romain Naour Date: Sat, 23 Sep 2017 23:24:05 +0200 Subject: [PATCH] package/flex: disable reallocarray MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This doesn't compile with glibc 2.26 where reallocarray() as been introduced. It's a nasty issue, when reallocarray() is available for the target, flex will build a small tool called stage1flex for the host (using _FOR_BUILD) but with the config.h generated for the target. When the host doesn't have a glibc >= 2.26, reallocarray() is never defined while building stage1flex: misc.c:147:8: warning : implicit declaration of function « reallocarray » [-Wimplicit-function-declaration] mem = reallocarray(NULL, (size_t) size, element_size); ^~~~~~~~~~~~ misc.c:147:6: warning : assignment makes pointer from integer without a cast [-Wint-conversion] mem = reallocarray(NULL, (size_t) size, element_size); ^ Disable reallocarray for now, reallocarray() support may be enabled in a followup patch. Fixes: stage1flex-misc.o: In function `allocate_array': misc.c:(.text+0x38f): undefined reference to `reallocarray' stage1flex-misc.o: In function `reallocate_array': misc.c:(.text+0xc8a): undefined reference to `reallocarray' collect2: error: ld returned 1 exit status Signed-off-by: Romain Naour Signed-off-by: Arnout Vandecappelle (Essensium/Mind) --- package/flex/flex.mk | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/package/flex/flex.mk b/package/flex/flex.mk index b78269952e..0196624e9a 100644 --- a/package/flex/flex.mk +++ b/package/flex/flex.mk @@ -10,7 +10,8 @@ FLEX_INSTALL_STAGING = YES FLEX_LICENSE = FLEX FLEX_LICENSE_FILES = COPYING FLEX_DEPENDENCIES = $(TARGET_NLS_DEPENDENCIES) host-m4 -FLEX_CONF_ENV = ac_cv_path_M4=/usr/bin/m4 +FLEX_CONF_ENV = ac_cv_path_M4=/usr/bin/m4 \ + ac_cv_func_reallocarray=no HOST_FLEX_DEPENDENCIES = host-m4 define FLEX_DISABLE_PROGRAM -- 2.30.2
