| <p>Deprecated. Do not use.</p> |
| <p>The macros provided by this module were once intended for use by |
| cross-compiling toolchain files when CMake was not able to automatically |
| detect the compiler identification. Since the introduction of this module, |
| CMake’s compiler identification capabilities have improved and can now be |
| taught to recognize any compiler. Furthermore, the suite of information |
| CMake detects from a compiler is now too extensive to be provided by |
| toolchain files using these macros.</p> |
| <p>One common use case for this module was to skip CMake’s checks for a |
| working compiler when using a cross-compiler that cannot link binaries |
| without special flags or custom linker scripts. This case is now supported |
| by setting the <span class="target" id="index-0-variable:CMAKE_TRY_COMPILE_TARGET_TYPE"></span><a class="reference internal" href="../variable/CMAKE_TRY_COMPILE_TARGET_TYPE.html#variable:CMAKE_TRY_COMPILE_TARGET_TYPE" title="CMAKE_TRY_COMPILE_TARGET_TYPE"><code class="xref cmake cmake-variable docutils literal"><span class="pre">CMAKE_TRY_COMPILE_TARGET_TYPE</span></code></a> variable in the |
| toolchain file instead.</p> |
| <hr class="docutils" /> |
| <p>Macro CMAKE_FORCE_C_COMPILER has the following signature:</p> |
| <div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">CMAKE_FORCE_C_COMPILER</span><span class="p">(</span><span class="o"><</span><span class="n">compiler</span><span class="o">></span> <span class="o"><</span><span class="n">compiler</span><span class="o">-</span><span class="nb">id</span><span class="o">></span><span class="p">)</span> |
| </pre></div> |
| </div> |
| <p>It sets CMAKE_C_COMPILER to the given compiler and the cmake internal |
| variable CMAKE_C_COMPILER_ID to the given compiler-id. It also |
| bypasses the check for working compiler and basic compiler information |
| tests.</p> |
| <p>Macro CMAKE_FORCE_CXX_COMPILER has the following signature:</p> |
| <div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">CMAKE_FORCE_CXX_COMPILER</span><span class="p">(</span><span class="o"><</span><span class="n">compiler</span><span class="o">></span> <span class="o"><</span><span class="n">compiler</span><span class="o">-</span><span class="nb">id</span><span class="o">></span><span class="p">)</span> |
| </pre></div> |
| </div> |
| <p>It sets CMAKE_CXX_COMPILER to the given compiler and the cmake |
| internal variable CMAKE_CXX_COMPILER_ID to the given compiler-id. It |
| also bypasses the check for working compiler and basic compiler |
| information tests.</p> |
| <p>Macro CMAKE_FORCE_Fortran_COMPILER has the following signature:</p> |
| <div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">CMAKE_FORCE_Fortran_COMPILER</span><span class="p">(</span><span class="o"><</span><span class="n">compiler</span><span class="o">></span> <span class="o"><</span><span class="n">compiler</span><span class="o">-</span><span class="nb">id</span><span class="o">></span><span class="p">)</span> |
| </pre></div> |
| </div> |
| <p>It sets CMAKE_Fortran_COMPILER to the given compiler and the cmake |
| internal variable CMAKE_Fortran_COMPILER_ID to the given compiler-id. |
| It also bypasses the check for working compiler and basic compiler |
| information tests.</p> |
| <p>So a simple toolchain file could look like this:</p> |
| <div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">include</span> <span class="p">(</span><span class="n">CMakeForceCompiler</span><span class="p">)</span> |
| <span class="nb">set</span><span class="p">(</span><span class="n">CMAKE_SYSTEM_NAME</span> <span class="n">Generic</span><span class="p">)</span> |
| <span class="n">CMAKE_FORCE_C_COMPILER</span> <span class="p">(</span><span class="n">chc12</span> <span class="n">MetrowerksHicross</span><span class="p">)</span> |
| <span class="n">CMAKE_FORCE_CXX_COMPILER</span> <span class="p">(</span><span class="n">chc12</span> <span class="n">MetrowerksHicross</span><span class="p">)</span> |
| </pre></div> |
