Hi All,

I tried the LibTooling example, and when I compile I got error like this :

[root@localhost Clang-tutorial-master]# sudo make
clang++ -I/home/krishan/llvm/tools/clang/include -I/home/krishan/buildllvm/tools/clang/include -I/home/krishan/llvm/include -I/home/krishan/buildllvm/include -D_DEBUG -D_GNU_SOURCE -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS -O3 -fomit-frame-pointer -std=c++11 -fvisibility-inlines-hidden -fno-exceptions -fno-rtti -fPIC -Woverloaded-virtual -ffunction-sections -fdata-sections -Wcast-qual -fno-rtti -c -o tutorial1.o tutorial1.cpp

Please help me on this, and give me some solution…

Hi Krish

Hi All,

1. You shouldn't build stuff as root.
2. If you are root, why are you using sudo ?

clang++ -I/home/krishan/llvm/tools/clang/include
-I/home/krishan/buildllvm/tools/clang/include -I/home/krishan/llvm/include
-I/home/krishan/buildllvm/include -D_DEBUG -D_GNU_SOURCE
-D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS -O3
-fomit-frame-pointer -std=c++11 -fvisibility-inlines-hidden -fno-exceptions
-fno-rtti -fPIC -Woverloaded-virtual -ffunction-sections -fdata-sections
-Wcast-qual -fno-rtti -c -o tutorial1.o tutorial1.cpp

What operating system are you using?
If it's Linux, which distribution is it?
Where is clang++? Did you install a package or did you build it
yourself? If you built it yourself, did you run 'make install'
afterwards?

Run the compiler command from above but add the -v switch, like this:

clang++ -v -I/home/krishan/llvm/tools/clang/include
-I/home/krishan/buildllvm/tools/clang/include
-I/home/krishan/llvm/include -I/home/krishan/buildllvm/include
-D_DEBUG -D_GNU_SOURCE -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS
-D__STDC_LIMIT_MACROS -O3 -fomit-frame-pointer -std=c++11
-fvisibility-inlines-hidden -fno-exceptions -fno-rtti -fPIC
-Woverloaded-virtual -ffunction-sections -fdata-sections -Wcast-qual
-fno-rtti -c -o tutorial1.o tutorial1.cpp

and show us the output.
