From mboxrd@z Thu Jan 1 00:00:00 1970 From: Samuel Martin Date: Thu, 8 May 2014 23:58:55 +0200 Subject: [Buildroot] [PATCH] cmake: forward HOST_{C, LD}FLAGS as cmake flags Message-ID: <1399586335-22928-1-git-send-email-s.martin49@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net During the CMake bootstrap phase, the {C,LD}FLAGS set in the bootstrap environment are not forwarded/converted as CMake flags. The CMake build contains a bootstrap phase building a minimal CMake program using a standard Makfile, then reconfigures itself with this minimal program. On system with no ncurses installed, and because the prefix option points to $(HOST_DIR)/usr, if host-cmake was built after host-ncurses, then ncurses libraries and headers are correctly find (in the host tree) during the second configuration (because of the prefix). However, it fails at building ccmake (the curses interface) because the CMAKE_C_FLAGS, CMAKE_CXX_FLAGS and CMAKE_EXE_LINKER_FLAGS do not point to the host tree. Because these flags are needed when running the bootstrap script, this patch makes sure the same flags are set when running the second configuration.
