[cfe-users] question about building
I'm new to LLVM and also new to Cmake. I've checked out multiple LLVM projects including clang (see below for list of projects checked out). I made the build directory. My question has three possible answers - A,B, or C, but if the answer is neither of those 3 can you please describe in detail what the correct answer is. My question is this, "Can I run cmake (A) with the path ONLY to the root of the LLVM project to build ALL of the projects I checked out, or (B) do I have to supply the path to the root of all the projects I checked out to cmake at once, or (C) do I run cmake multiple times in succession with a new path each time to the respective project I am building" Thank you in advance #.

[cfe-users] can't find binary/executable
Hi, my exact question is in paragraph numbered 3 below. The first two paragraphs have prefatory information. 1. I ran the following command to build llvm and clang (with the intention of building the examples), `sudo cmake -DLLVM_BUILD_EXAMPLES=1 -DCLANG_BUILD_EXAMPLES=1 -DCMAKE_BUILD_TYPE="Release" ../llvm` 2. After it completed, I ran `make` and `make install`. The output from `make install` showed this (for the PrintFunctions example in /clang/examples) [ 92%] Built target PrintFunctionNames_exports [ 92%] Built target PrintFunctionNames -- Installing: /usr/local/lib/PrintFunctionNames.so 3. Question: is there a step I need to do to run the PrintFunctionNames example? I can't find a binary/executable? 4. In the directory build/tools/clang/examples, I have this analyzer-plugin clang-interpreter CMakeFiles PrintFunctionNames AnnotateFunctions cmake_install.cmake Makefile 5. In build/tools/clang/examples/PrintFunctionNames/ I have this cmake_install.cmake Makefile CMakeFiles PrintFunctionNames.exports ___ cfe-users mailing list cfe-users@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-users
Re: [cfe-users] can't find binary/executable
Update, Sorry about that I found the instructions in the ReadMe for the PrintFunctionsDir, but they don't seem to be update or I'm running them wrong. The ReadMe says the following: "This is a simple example demonstrating how to use clang's facility for providing AST consumers using a plugin. Build the plugin by running `make` in this directory. Once the plugin is built, you can run it using: -- Linux: $ clang -cc1 -load ../../Debug+Asserts/lib/libPrintFunctionNames.so -plugin print-fns some-input-file.c $ clang -cc1 -load ../../Debug+Asserts/lib/libPrintFunctionNames.so -plugin print-fns -plugin-arg-print-fns help -plugin-arg-print-fns --example-argument some-input-file.c $ clang -cc1 -load ../../Debug+Asserts/lib/libPrintFunctionNames.so -plugin print-fns -plugin-arg-print-fns -an-error some-input-file.c" My ".so" file is /usr/local/lib/PrintFunctionNames.so Whether I run clang -cc1 -load ../../Debug+Asserts/lib/libPrintFunctionNames.so -plugin print-fns hello.c or clang -cc1 -load /usr/local/lib/PrintFunctionNames.so -plugin print-fns hello.c I get this output error: unable to load plugin '../../Debug+Asserts/lib/libPrintFunctionNames.so': 'Service unavailable' On Fri, Apr 21, 2017 at 9:50 AM, Michael Mitchell < michaeljohnmitch...@gmail.com> wrote: > Hi, > my exact question is in paragraph numbered 3 below.

Re: [cfe-users] can't find binary/executable
Problems been solved. For anyone else with the same question, the problem was that I wasn't using the clang that I had built the file against (clang came installed by default on the system). When I ran ./build/bin/clang and followed the instructions at this tutorial it worked fine https://clang.llvm.org/docs/ClangPlugins.html On Fri, Apr 21, 2017 at 10:07 AM, Michael Mitchell < michaeljohnmitch...@gmail.com> wrote: > Update, > > Sorry about that I found the instructions in the ReadMe for the > PrintFunctionsDir, but they don't seem to be update or I'm running them > wrong.
