Subject: clang-3.3: Support Headers not picked up cstddef and more

Date: Wed, 29 May 2013 22:33:55 +0000

Package: clang-3.3
Version: 1:3.3~svn179851-1~exp1
Severity: normal

Dear Maintainer,

Since so many packages have been pushed from experimental into Sid with GCC-4.7 and part of GCC-4.8 I decided to see how building LLVM/Clang from trunk works. It fails with assembly issues I'll file later using GCC-4.7 as the CC.

Now, I decide to install the LLVM-3.3/Clang-3.3 toolchain in its entirety to see how well it builds and this is what I get:

Scanning dependencies of target LLVMSupport

----------------

What is it with this latest transition in GCC-4.7.4 and GCC-4.8 that seems to throw this error each and every time I test it? Am I missing a package that can resolve the relocation of these header file paths or does Debian need to contact LLLVM/Clang and make sure those paths are included when building the infrastructure?

Sincerely,

Marc J. Driftmeyer

Could you try to build the same way the package it built ? For now, I do
not support cmake build.

Thanks

Cmake aside which is going to be the defacto standard within the 
LLVM/Clang system, I found out the error with cstddef: After installing 
libstdc++6-4.7-pic this error is gone compiling 
LLVM/Clang/LLDB/Compiler-RT/Libcxx trunk against llvm-3.3 latest [have 
not yet tested bleeding edge 3.4] in Debian.

Now that <cstddef> no longer fails I've got this presently from trunk:

I'm going to track down and see if the latest checkout resolves this 
issue or not. I wish I had a deeper knowledge of both GCC and LLVM/Clang 
[though in this area I am gaining in] so as to not waste your time.



The other `error' I had with assembly [I alluded to as being a different 
bug] was the fact with a mixed gcc-4.7/gcc-4.8 transition from 
Experimental I checked more closely the cmake config and noted gcc-> 
gcc-4.8 while g++ -> g++-4.7 thus the error.

With the standard: -DCMAKE_CXX_COMPILER=/usr/bin/g++-4.7 
-DCMAKE_C_COMPILER=/usr/bin/gcc-4.7 ../llvm in a simple cmake config 
everything built from trunk.

I'm not sure what reason gcc-4.8 is set to default for gcc and thus cc 
compiler option, but the symlink states Feb 18, 2013 on this change, 
while the g++ symlink dates back to September 12, 2012.

Sincerely,

Marc J. Driftmeyer

Cmake build is not completed compare to the autotools.
See:
http://llvm.org/bugs/show_bug.cgi?id=15732
Until they are fixed, I am not planning to support two build system.

Even if I started some works on that:

Interesting. Thanks for the feedback.

fixed 710322 3.3-1
thanks

Hi,

On my system at least, this bug is fixed.

-- bar.cpp --
#include <cstddef>

int main() {

	return 0;
}

$ clang++ bar.cpp
$ ./a.out

If it stills fails on your system, please provide a testcase and reopen it.

Thanks
S
