Hi I am trying to create a new LLVM project that uses autoconf to configure it. the example requires me to define * LLVM_SRC_ROOT - The root of the LLVM source tree. * LLVM_OBJ_ROOT - The root of the LLVM object tree Is this required? Why? I just want to use the libraries that were installed using Ubuntu 10.04. I can compile programs using llvmc $ llvmc --version Low Level Virtual Machine (http://llvm.org/): llvm version 2.7 ( 2.7-0ubuntu1) Optimized build. Built Apr 28 2010 (14:19:53).

AC_CHECK_LIB is what you probably want. http://www.gnu.org/software/hello/manual/autoconf/Libraries.html -eric -------------- next part -------------- An HTML attachment was scrubbed...

The LLVM build system allows for external LLVM projects to re-use its Makefile infrastructure. In short, it allows external projects (which are not part of the LLVM source tree) to build off of the LLVM build system; this allows external projects to write LLVM-style Makefiles that just specify the library or tool name to build, and the LLVM build system takes care of the rest (like linking in LLVM libraries, using pre-defined rules for compiling C++ code to object files, finding LLVM header files, etc). This whole system is documented at http://llvm.org/docs/Projects.html. If you've installed LLVM headers and libraries somewhere (such as in /usr/local/include and /usr/local/lib) and don't wish to reuse the LLVM build system, then you obviously don't need to worry about writing your autoconf scripts and Makefiles the LLVM way. Instead, you would just use AC_CHECK_LIB to locate the LLVM libraries you need, as Eric has described. -- John T.> > AC_CHECK_LIB is what you probably want. > > http://www.gnu.org/software/hello/manual/autoconf/Libraries.html > > -eric-------------- next part -------------- An HTML attachment was scrubbed...
