This is one of those things where you have to have the setting right before any possible TRY_COMPILE actions in any CMakeLists files. It's *conceptually* equivalent to changing the compiler.<br><br>What you tried by using -DCMAKE_AR should work if you start with an empty binary tree. (And starting with an empty binary tree is a reasonable thing to do when essentially everything needs to be rebuilt anyway.)<br>

</p>
<p><font face="Arial" size="2"> We're using the Intel compiler for some of our builds of ITK. The "-fast" option tries to statically link. So I thought I'd build Insight statically. The problem occurred when I tried to use the static libraries generated by "/usr/bin/ar", and the symbols could not be found. Turns out that the Intel compiler requires you to use their version of ar, namely xiar.</font></p>
<p><font face="Arial" size="2"> I tried all the obvious things like changing "CMAKE_AR" in my cache file, defining an AR environment variable, a -DCMAKE_AR=xiar to CMake, etc. Turns out that the value is cached in CMakeFiles/CMakeCXXCompiler.cmake, but no good way to change it (the CMakeCXXCompiler.cmake overrides CMakeCache.txt) short of editing the file (which is what I ended up doing).</font></p>
<p><font face="Arial" size="2"> Could the CMake developers provide an easy way to override the CMAKE_AR command to make linking statically with the Intel compiler straightforward?</font></p>
