...how to create R packages using C++ classes. For this purpose I have written a small package MyClass (which I try to attach since I do not have access to a website). MyClass has methods WriteFileC() and WriteFileCpp() which implement C-style and C++-style writing of a table to a file using FILE or ofstream respectively, and the corresponding R-functions writeFileC.R and writeFileCpp.R. While I can compile and execute my package w/o problems on Fedora Core 4, I can only execute writeFileC.R on my Intel-MacBook Pro, but not writeFileCpp.R. Executing my functions I get the following output: > lib...

We can get the llvm assembler for a Module with something as simple as std::ofstream f("code.llvm"); f << *M; Is there a method for obtaining the llvm assembler of a given Function? -- Óscar

It seems that support for dumping text representation of LLVM objects to standard channels and C++ output streams was removed. My guess is that now we must use errs() instead of std::cerr, llvm::raw_fd_ostream instead of std::ofstream, etc. The changes are not trivial, as for instance llvm::raw_fd_ostream without flags fails if the file exists, but std::ofstream does not. The changes include using new names for flags that already exist on the standard namespace (F_Force instead of O_TRUNC, etc). Is all this an unintended chang...

Hello, Any call to xapian-compact compiled for Win32/Cygwin ultimately fails when it tries to rename/replace iamflint.tmp with the final version. The reason is you cannot rename an opened file with Win32/Cygwin libc. To correct this, just close the output ofstream (xapian-compact.cc(534)) like: """ ofstream output(dest.c_str()); if (!output.write(buf, input.gcount())) { cerr << argv[0] << ": error writing '" << dest << "': " << strerror(errno) << endl; exit(1); } output.close...

Hi, # TL;DR I've been building an application with and without the address sanitizer (with gcc 5.3 and clang 3.7.1) and I've observed that the application's behaviour changes (assertion hit/ not hit). I'm wondering if this could be a bug in address sanitizer or if the application I'm running is just buggy (e.g. doing bad things like relying on memory layout, etc.). I'm

This should be enough for clients which want to keep using std::ostream. > The changes are not trivial, as for instance ll...

I think something like "F->print(f);" will do the right thing. -Eli

Also, each of LLVM <=2.5, 2.6 and 2.7(svn) provide their own, incompatible llvm::raw_fd_ostream constructors. This makes it unneccessarily hard to su...
