I am trying to create a project in my home directory based off the instructions in http://llvm.org/docs/Projects.html. I have completed step 4 requiring me to set the values in autoconf/configure.ac In step 5, when I run AutoRegen.sh, I get the following error: Can't find the LLVM autoconf/m4 directory. The project should be checked out to projects directory So, I assumed that I set AC_CONFIG_AUX_DIR incorrectly in configure.ac. I tried setting it to an absolute path and a relative path but had no luck. Then I looked at AutoRegen.sh, and it seems to have a variable called llvm_m4 that is hardcoded to either ../../../autoconf/m4 or ../../llvm/autoconf/m4. If I hardcode in another option that allows llvm_m4 to be hardcoded to the same value that I set AC_CONFIG_AUX_DIR to, then I am able to run AutoRegen.sh. Am I doing something wrong? Regards, Ryan
It's complaining about the LLVM autoconf/m4 directory which contains the m4 macros that are used in your project's configure.ac. By convention, your project should be in the llvm/projects directory so that you have: 1. llvm/autoconf 2. llvm/projects/yourProj/autoconf The AutoRegen.sh in #2 is looking for #1. By convention that should be located at ../../../autoconf/m4. AC_CONFIG_AUX_DIR has nothing to do with it, as that comes into play only when autoconf is run, not when AutoRegen.sh is running. Probably the only thing you're doing "wrong" is not placing your project in the llvm/projects directory. If you need to have your project elsewhere, then what you did (change llvm_m4) is correct. But, please be aware, the directory you want is *not* your project's autoconf directory, but LLVM's autoconf directory. Reid. On Fri, 2006-04-14 at 18:40 -0500, Ryan M.

Thank you for the response. I guess the only thing that is confusing is that the LLVM documentation, at http://llvm.org/docs/Projects.html under the "Create a Project from the Sample Project" heading, indicates that (1) you can place your project *anywhere* you want, and (2) that you are supposed to use the AutoRegen.sh script as is. However, that seems not to be the case. The reason my project is not in the LLVM projects directory is because it is in a CVS directory as part of a different project I am working on. Again thanks for the help. Ryan Reid Spencer wrote:> It's complaining about the LLVM autoconf/m4 directory which contains the > m4 macros that are used in your project's configure.ac.
