I applied your patch but building fails however: It looks you are trying to cross compile something that needs to be compiled for the host. Is there something defined in your environment for cross compiling? -- Bas ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel

The mail escaped before being finished...
The text
Line: gcc -Os -pipe -march=armv5te -mtune=marvell-f -funit-at-a-time
cmake_bootstrap_22734_test.c -o cmake_bootstrap_22734_test
in the output you posted lets me suspect that you exported a CFLAGS
define like
export CFLAGS=-march=armv5te -mtune=marvell-f -funit-at-a-time
somewhere.
This is a fresh checkout from trunk and I am trying to build for Marvell
Kirkwood ('Seagate Dockstar).
The CFLAGS from target/linux/kirkwood/Makefile are overriding include/
host-build.mk. So removing include $(INCLUDE_DIR)/target.mk from
tools/cmake/Makefile did it for me. Did you include it on purpose?

[OpenWrt-Devel] [PATCH] Add CMake host tool support [V2]
Hi all, The attached patch against trunk adds CMake host tool support. When CONFIG_CMAKE is set in .config, the CMake tools will be build and installed in staging_dir/host/bin. To enable CONFIG_CMAKE, select Advanced configuration options (for developers) in the main menu and select Build CMake tool. When a package needs CMake to build, it just needs to have the line DEPENDS:=...@cmake in the Makefile. Please review this patch and add it to trunk. I'm working on creating an OpenWRT package of Gammu (http://wammu.eu/gammu/) that needs cmake to build, see https://dev.openwrt.org/ticket/7649 Can this patch please be added to backfire too? I'm working on a customer project based upon backfire that needs Gammu for communication with a GSM modem. It would be very nice to use backfire unmodified in the project. Revision history: V1: first attempt V2: remove target compiler flags inclusion for native build Thanks a lot in advance, Regards, -- Bas cmake.diff Description: Binary data ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel

Now the fishy part begins. :-) We need to tell cmake that we are cross compiling. Here is a good start: http://www.cmake.org/Wiki/CMake_Cross_Compiling I guess we need a toolchain file. I'm wondering if we can provide one for all packages that use cmake (it should be). So that is something that tools/cmake/Makefile could generate. Package should than simply call cmake -DCMAKE_TOOLCHAIN_FILE=.../staging_dir/somewhere/tc_file.cmake I'll take a look at it over the weekend. Hopefully, I can get the gammu package working as well. Thanks for your feedback so far! Regards, Bas. -- Bas. ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
