From: Bernd Kuhls Date: Sat, 27 May 2017 11:52:37 +0000 (+0200) Subject: package/opencv: fix build with old glibc versions X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cbf2b6e3db65500f7bb29aa029a620570026373c;p=buildroot.git package/opencv: fix build with old glibc versions Prior to glibc 2.18, definitions like SIZE_MAX or INT_FAST32_MAX from were only made available for C code, or in C++ if __STDC_LIMIT_MACROS was defined. The code from jasper uses such definitions, without defining __STDC_LIMIT_MACROS. Unfortunately, defining __STDC_LIMIT_MACROS in the jasper headers doesn't work, since has already been included before, at a point where __STDC_LIMIT_MACROS was not defined. So to solve this problem, we simply pass -D__STDC_LIMIT_MACROS in CXXFLAGS when building opencv with jasper support. This patch uses the same solution used for libraw: https://git.buildroot.net/buildroot/commit/package/libraw?id=d246cf5fd01bb0d20a0e64194ffed514ea8dd0aa Fixes: http://autobuild.buildroot.net/results/095/095f7574afdb633c59a625cd063de03644b6d3a7/ Signed-off-by: Bernd Kuhls Signed-off-by: Thomas Petazzoni --- diff --git a/package/opencv/opencv.mk b/package/opencv/opencv.mk index ff5ab02b16..92cfd431a0 100644 --- a/package/opencv/opencv.mk +++ b/package/opencv/opencv.mk @@ -192,7 +192,8 @@ OPENCV_CONF_OPTS += -DWITH_GTK=OFF endif ifeq ($(BR2_PACKAGE_OPENCV_WITH_JASPER),y) -OPENCV_CONF_OPTS += -DWITH_JASPER=ON +OPENCV_CONF_OPTS += -DWITH_JASPER=ON \ + -DCMAKE_CXX_FLAGS="$(TARGET_CXXFLAGS) -D__STDC_LIMIT_MACROS" OPENCV_DEPENDENCIES += jasper else OPENCV_CONF_OPTS += -DWITH_JASPER=OFF
