[LLVMdev] Unable to do even basic Clang tutorial

I'm trying to do the tutorials at:

https://github.com/loarabia/Clang-tu...i/TutorialOrig

and I can't even do the first tutorial. I installed LLVM 3.1 and Clang 3.1 and when I do:

~/loarabia-Clang-tutorial-3d79443$ clang++ tutorial1.cpp In file included from tutorial1.cpp:5: In file included from ./llvm/Support/raw_ostream.h:17: ./llvm/Support/llvm/ADT/StringRef.h:13:10: fatal error: 'llvm/Support/type_traits.h' file not found

include "llvm/Support/type_traits.h"
^
1 error generated.

Do you know what I am doing wrong? I'm not sure what is the best way to handle this header file problem.

I'm running Ubuntu 12.04.

Thank you.

the tutorial seems to use LLVM 3.0 and probably hasn't been updated to LLVM 3.1
yet.

Ciao, Duncan.

Did you build it or "install" it from a package? If you build it, then
you need do a 'make install' and include the installed location of
clang/llvm headers directories in your include path.

I downloaded the 3.1 LLVM and Clang sources.

I followed the directions at: http://clang.llvm.org/get_started.html

I am able to use Clang to compile stuff, but I could already do that with GCC.

I'm trying to use Clang for parsing code, but I can't even get started.

Can you tell me how to "include the installed location of clang/llvm headers directories in your include path"?

Thanks!

Use the -I<install path>/include .

This directory <install path>/include should look something like:

clang/ clang-c/ llvm/ llvm-c/

Hi Ashok,

The documentation suggests that I put clang inside of llvm/tools and so I have two separate include directories. I tried both of them and neither worked:

$ clang++ -I llvm/include tutorial1.cpp

In file included from tutorial1.cpp:5:

In file included from llvm/include/llvm/Support/raw_ostream.h:17:

In file included from llvm/include/llvm/ADT/StringRef.h:13:

llvm/include/llvm/Support/type_traits.h:20:10: fatal error: 'llvm/Support/DataTypes.h' file not found

#include "llvm/Support/DataTypes.h"

^

1 error generated.

$ clang++ -I llvm/tools/clang/include/ tutorial1.cpp

tutorial1.cpp:5:10: fatal error: 'llvm/Support/raw_ostream.h' file not found

#include "llvm/Support/raw_ostream.h"

^

1 error generated.

Any help you can provide is very much appreciated.

The "make install" should collect everything into your <install path>.
The <install path> will then have bin, lib and include dirs.

And you should be able to specify the install path with the --prefix option when configuring. I believe the default is /usr/local (see: configure --help to verify).

I followed the directions at http://clang.llvm.org/get_started.html and after make, I did make install.

The only thing I didn't do though was make at the clang directory as the directions said clang would automatically get built.

When I do make in the clang directory, I get:

~/llvm/tools/clang$ make

../../Makefile.common:61: ../../Makefile.config: No such file or directory

../../Makefile.common:69: /Makefile.rules: No such file or directory

make: *** No rule to make target `/Makefile.rules'. Stop.

Do you think that the problem is with the distro I chose? I'm using Ubuntu 12.04.

$ ls /usr/local/include/

llvm llvm-c

Does this mean Clang wasn't installed properly on my Ubuntu machine?

I did a make install in my ~/build directory and I thought this would install Clang. At least there is a /usr/bin/clang.

When I do make in my ~/build/tools/clang directory, I get:

~/build/tools/clang$ make

make[1]: Entering directory `/home/username/build/tools/clang/utils/TableGen'

make[1]: Nothing to be done for `all'.

Hi Ashok,

As I mentioned in my earlier e-mail, my /usr/local/include does not have clang/ or clang-c/.

I'm unable to do a make or make install in the Clang build directory. How do I fix this?

Thanks!

Looks like your make/install is incomplete wrt clang. I follow the
instuctions for checking out the sources but build using cmake instead
of configure:

> cmake -G ""Unix Makefiles" -DLLVM_TARGETS_TO_BUILD="X86" -DCMAKE_BUILD_TYPE="Release" -DCMAKE_INSTALL_PREFIX="../bin" ../llvm
> make install

This builds and installs llvm+clang in the bin directory one level above
llvm. I tried using configure earlier but had some problems.

Hi Ashok,

I created a new Ubuntu 12.04 virtual machine and followed directions except that I know use your cmake command instead of configure, and I got the error below.

Any help is very much appreciated.

OK. Thanks. I now get the following error (which appears to be a problem w/ the tutorial itself?):

Uhmmm... sorry if I sound blunt, but you are trying to use a C++
framework for doing a complex task when it is obvious that you are not
familiar enough with the usage of a C++ toolkit (compiler+linker).

In my humble opinion, you should learn well how C++ development works
(and learn C++ well too). Then you can start using the Clang libraries
fixing yourself all those problems you found so far in no time.

You will need to link to the LLVM/clang libraries. To get the correct
flags, you can run:
./llvm-config --ldflags --libs

and use the flags reported.
