| How To Compile with CMake |
| |
| Building with CMake |
| ========================== |
| This document describes how to compile, build and install curl and libcurl |
| from source code using the CMake build tool. To build with CMake, you will |
| of course have to first install CMake. The minimum required version of |
| CMake is specifed in the file CMakeLists.txt found in the top of the curl |
| source tree. Once the correct version of CMake is installed you can follow |
| the instructions below for the platform you are building on. |
| |
| CMake builds can be configured either from the command line, or from one |
| of CMake's GUI's. |
| |
| Important notice |
| ================== |
| If you got your curl sources from a distribution tarball, make sure to |
| delete the generic 'include/curl/curlbuild.h' file that comes with it: |
| rm -f curl/include/curl/curlbuild.h |
| |
| The purpose of this file is to provide reasonable definitions for systems |
| where autoconfiguration is not available. CMake will create its own |
| version of this file in its build directory. If the "generic" version |
| is not deleted, weird build errors may occur on some systems. |
| |
| Command Line CMake |
| ================== |
| A command line build of Curl is similar to the autotools build of Curl. It |
| consists of the following steps after you have unpacked the source. |
| # 1st create an out of source build tree parallel to the curl source |
| # tree and change into that directory |
| mkdir curl-build |
| cd curl-build |
| # now run CMake from the build tree, giving it the path to the top of |
| # the Curl source tree. CMake will pick a compiler for you. If you |
| # want to specifiy the compile, you can set the CC environment |
| # variable prior to running CMake. |
| cmake ../curl |
| make |
| # currently make test is not implemented |
| #make test |
| # Install to default location: |
| make install |
| |
| ccmake |
| ========= |
| CMake comes with a curses based interface called ccmake. To run ccmake on |
| a curl use the instructions for the command line cmake, but substitue |
| ccmake ../curl for cmake ../curl. This will bring up a curses interface |
| with instructions on the bottom of the screen. You can press the "c" key |
| to configure the project, and the "g" key to generate the project. After |
| the project is generated, you can run make. |
| |
| cmake-gui |
| ========= |
| CMake also comes with a Qt based GUI called cmake-gui. To configure with |
| cmake-gui, you run cmake-gui and follow these steps: |
| 1. Fill in the "Where is the source code" combo box with the path to |
| the curl source tree. |
| 2. Fill in the "Where to build the binaries" combo box with the path |
| to the directory for your build tree, ideally this should not be the |
| same as the source tree, but a parallel diretory called curl-build or |
| something similar. |
| 3. Once the source and binary directories are specified, press the |
| "Configure" button. |
| 4. Select the native build tool that you want to use. |
| 5. At this point you can change any of the options presented in the |
| GUI. Once you have selected all the options you want, click the |
| "Generate" button. |
| 6. Run the native build tool that you used CMake to genratate. |
