Here you invoke cmake, specifying the path to your toolchain file and the path to the import_executables.cmake that you have just built on the previous step. Now the helpers are built and you can cross-compile: $ mkdir target Do it like this (assuming you're in the mariadb source tree): $ mkdir host When cross-compiling these tools naturally should be built for the host architecture, not for the target architecture. Note that during the build few helper tools are compiled and then immediately used to generate more source files for this very build. Normally these MariaDB configuration settings are detected by running a small test program, and it cannot be done when cross-compiling. With appropriate values for your target architecture. Besides cmake specific variables it should have, at least SET(STACK_DIRECTION -1) To cross-compile with cmake you will need a toolchain file. Also enable the "mariadb server" below the "mysql support" option. After C++ is enabled MariaDB is an option under "Target Packages" ->"Libraries" -> "Databases" -> "mysql support" -> "mysql variant" -> "mariadb". In the menuconfig you need to enable "Enable C++ Support" first under "Toolchain". Cmake linux to mac toolchain file how to#I've also searched on how to build CMake, but most searches turn up how to build other things with CMake rather than building CMake itself.Buildroot is a way to cross compile MariaDB and other packages into a root filesystem. I've tried searching for CMake dependencies or system requirements and can't find anything. I'd try installing glibcxx 3.4.14 on the Linux box, but it doesn't look like it's available for this processor. I got build errors, and that binary didn't work either. My last effort involved trying to statically cross-compile CMake to hopefully get rid of the linking error with cmake -DCMAKE_TOOLCHAIN_FILE=./toolchain-technologic.cmake -DBUILD_SHARED_LIBS=OFF -DCMAKE_BUILD_TYPE=Release -DCMAKE_EXE_LINKER_FLAGS_RELEASE="-static". I don't know how to check which is happening or if something else is happening that I don't know about. I've never cross-compiled before, but I can see one of two scenarios happening: either the binary got created with a link to a higher version of glibcxx on the host machine or the manufacturer's toolchain is more modern than their image. Sure enough, the library is not there: prompt# strings /usr/lib/libstdc++.so.6 | grep GLIBC However, use of the binary on the Linux box gives the errorĬmake: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.14' not found (required by cmake) SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY) SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY) # For libraries and headers in the target directories SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER) # Search for programs in the build host directories SET(CMAKE_FIND_ROOT_PATH /pathto/crosstool-linux-gcc-4.5.2-gclibc-2.9-oabi/arm-unknown-linux-gnu /pathto/crosstool-linux-gcc-4.5.2-gclibc-2.9-oabi/arm-unknown-linux-gnu/arm-unknown-linux-gnu) SET(CMAKE_CXX_COMPILER /pathto/crosstool-linux-gcc-4.5.2-gclibc-2.9-oabi/arm-unknown-linux-gnu/bin/arm-unknown-linux-gnu-g++) SET(CMAKE_C_COMPILER /pathto/crosstool-linux-gcc-4.5.2-gclibc-2.9-oabi/arm-unknown-linux-gnu/bin/arm-unknown-linux-gnu-gcc) Here is my toolchain file: # This one is important When that failed, I downloaded the toolchain suggested on the manufacturer's website and used the cross-compiling guide at [to build the CMake executables. Cmake linux to mac toolchain file download#Next I tried to download and build CMake 2.8.8 on the Linux box itself, but it was too much for the system. I'd made progress installing the various libraries needed, but when I got to step 1.3.1 and tried to run CMake, I got the errorĬMake 2.8 or higher is required. I have to compile from source rather than use apt since Debian 6.0 (Squeeze) binaries require thumb support that the Cavium does not give, and not many of the needed packages are available for Debian 5.0 (Lenny). My overall goal is to get ROS running on the Linux box. My workstation is a Core i5 running Ubuntu 12.04 LTS (Precise Pangolin). It's currently running version 2.6.24.4 of the Linux kernel and Debian 5.0 (Lenny). System: The host is a Linux box with a Cavium ARM9 CPU. What I want to do may not be possible, but I'd at least like to know why it isn't possible if that's the case. In short I'm trying to cross compile CMake with CMake, and I don't think I'm linking libraries correctly.
