<div>> Hi Kevin,</div>
<div> </div>
<div>>> 2. I had no problem running the V3.0 regression tests according to the</div>
<div>>> instructions. However, the instructions in the Testing Infrastructure</div>
<div>>> Guide for running the Test Suite presume the existence and use of</div>
<div>>> llvm-gcc, <a href="http://llvm.org/docs/TestingGuide.html"><font color="#0000FF"><u>http://llvm.org/docs/TestingGuide.html</u></font></a></div>
<div>>> <<a href="http://llvm.org/docs/TestingGuide.html"><font color="#0000FF"><u>http://llvm.org/docs/TestingGuide.html</u></font></a>>, both on-line and in the rc4</div>
<div>>> kits. Now that llvm-gcc is gone for V3.0, it isn’t completely obvious how</div>
<div>>> to run the test-suite using clang rather than llvm-gcc. I’ve made a couple</div>
<div>>> stabs at it without success. If there is new documentation that I’ve</div>
<div>>> missed, please be kind when you point out where I should have looked. :-}</div>
<div> </div>
<div>> Pass LLVMCC_OPTION=clang ENABLE_BUILT_CLANG=1 to make when running the testsuite.</div>
<div> </div>
<div>Duncan,</div>
<div>Thanks for the quick response!</div>
<div> </div>
<div><font face="Calibri, sans-serif" size="2">Since I don’t have llvm-gcc installed, I tried to do the configure by doing a “cd” to the test-suite directory </font></div>
<div><font face="Calibri, sans-serif" size="2">and just doing a “./configure”. It appeared to do something useful in spite of the fact that the instructions</font></div>
<div><font face="Calibri, sans-serif" size="2">in the Testing Infrastructure Guide explicitly say that I need to pass the option: “—with-llvmgccdir=???” </font></div>
<div><font face="Calibri, sans-serif" size="2">to the ./configure step, and I don’t have such a directory (not having installed llvm-gcc). It isn’t totally</font></div>
<div><font face="Calibri, sans-serif" size="2">obvious if I should attempt to use a clang related directory in its place, or what that should be.</font></div>
<div><font face="Calibri, sans-serif" size="2"> </font></div>
<div><font face="Calibri, sans-serif" size="2">However, I don’t think the configure worked, because all attempts to issue any “make” or “gmake” in</font></div>
<div><font face="Calibri, sans-serif" size="2">the test-suite directory, with any targets or options whatsoever, results in an error message saying:</font></div>
<div><font face="Calibri, sans-serif" size="2"> </font></div>
<div><font face="Calibri, sans-serif" size="2">“Makefile.config:37: /home/kharris/Makefile.config: No such file or directory</font></div>
<div><font face="Calibri, sans-serif" size="2">make: *** No rule to make target `/home/kharris/Makefile.config'. Stop.”</font></div>
<div><font face="Calibri, sans-serif" size="2"> </font></div>
<div><font face="Calibri, sans-serif" size="2">The “make” appears to be expecting a “Makefile.config” file in my login directory. My hypothesis is that</font></div>
<div><font face="Calibri, sans-serif" size="2">this is the result of the missing “—with-llvmgccdir=” option. </font></div>
<div><font face="Calibri, sans-serif" size="2"> </font></div>
<div><font face="Calibri, sans-serif" size="2">The test-suite appears to have no useful documentation of its own – the “docs” and “website” directories</font></div>
<div><font face="Calibri, sans-serif" size="2">just have placeholder .html files. </font></div>
<div><font face="Calibri, sans-serif" size="2"> </font></div>
<div><font face="Calibri, sans-serif" size="2">I’ve tried to read the “configure” shell script, but it is fairly dense, fairly obscure shell code without any</font></div>
<div><font face="Calibri, sans-serif" size="2">helpful comments. </font></div>

<div><font face="Calibri, sans-serif" size="2">Thanks, Wei-Ren! The thread referenced is similar to this one. There is a good suggestion for a very long </font></div>
<div><font face="Calibri, sans-serif" size="2">“make” command that looks like it ought to work, except that it succumbs to the same problem described</font></div>
<div><font face="Calibri, sans-serif" size="2">above – the error message about the missing Makefile.config file. </font></div>
<div><font face="Calibri, sans-serif" size="2"> </font></div>
<div><font face="Calibri, sans-serif" size="2">Moreover, if you read to the end of the thread, you discover that the ultimate solution was to go ahead</font></div>
<div><font face="Calibri, sans-serif" size="2">and install llvm-gcc after all. </font></div>
<div><font face="Calibri, sans-serif" size="2"> </font></div>
<div><font face="Calibri, sans-serif" size="2">My take-away from all this is that the test-suite has not actually been upgraded to work without llvm-gcc</font></div>
<div><font face="Calibri, sans-serif" size="2">yet. The existence of the test-suite in the release directory for rc4 seems to imply that it has </font></div>
<div><font face="Calibri, sans-serif" size="2">been modified to work with clang in the absence of llvm-gcc, but perhaps that is too strong an </font></div>
<div><font face="Calibri, sans-serif" size="2">assumption? </font></div>
<div><font face="Calibri, sans-serif" size="2"> </font></div>
<div><font face="Calibri, sans-serif" size="2">Has anyone successfully configured and run the test-suite from rc4 without installing llvm-gcc?</font></div>
