It is safer to build the libraries with clang++ if you're going to later use those libraries with clang++(you can get the distro version of clang from your distro's repo). The same applies to g++.<br/> The master branch is the dev version. Release versions will be forked.<br/> +### FAQ + +#### tool complains that it can't find stddef.h +Tool complains that it cannot find `stddef.h` or some other similar header. If that happens to you , it's because the tool can't find the clang built-in headers. run `llvm-config --libdir`, then head on to `clang`. Inside that directory you should see one(or maybe more) llvm/clang versions. Pick the one you used to build cgrep against. Inside that directory there will be a directory named `include`. Pass that to the tool any way you see fit.<br/> +Alternatively, `$(llvm-config --libdir)/clang/$(llvm-config --version)/include` should give the path the tool needs to include. If you build your llvm/clang from upstream, this might not work. SVN bulds will have the svn string attached to the version number.<br/> +You could,for example, use `--extra-arg=-I/usr/lib/llvm-9/lib/clang/9.0.0/include` to call cgrep or you could just alias `cgrep` to `cgrep --extra-arg=-I/usr/lib/llvm-9/lib/clang/9.0.0/include`.<br/> + ### Acknowledgements Project mutator uses the following libraries: * [LLVM/Clang](http://llvm.org) |
