similar to: [LLVMdev] FreeBSD's 11.0-CURRENT contrib/llvm/include/llvm/ADT/IntrusiveRefCntPtr.h's IntrusiveRefCntPtr and its use violates C++ privacy rules

why llvm contains IntrusiveRefCntPtr instead of using only std::shared_ptr? IntrusiveRefCntPtr widely used in llvm and clang source code. Due to better performance? for example in main func of clang frontend: int cc1_main(ArrayRef<const char *> Argv, const char *Argv0, void *MainAddr) { ensureSufficientStack(); std::unique_ptr<CompilerInstance> Clang(new CompilerInstance());

This should be fixed in 5044196b412f. That helped a bit, but not yet fully. Looks like it might be still reachable memory, so leakcheck isn't that helpful. Oooh. I think I see.

You need to link in the libclang* as well.

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. On 7/10/2012 11:35 AM, NY Knicks Fan wrote: > OK.

I am using the clang API (version 3.1 - trunk 153913) to compile some very simple code as follows class MyClass { ~MyClass() ; }; MyClass::~MyClass() { } int main() { return 0; } My problem is that I get the error message: test.cpp:20:10: error: destructor cannot have a return type MyClass::~MyClass() If someone can point me to the right direction that would be great. It compiles fine if

Thanks Dimitry. That worked.

Manuel, After the discussion at last night, I have agreed that GetTemporaryDirectory() on Win32 would do bad thing, thank you. dir = GetTemporaryDirectory(); dir.eraseFromDisk(erase_contents = true); dir = GetTemporaryDirectory(); /* It doesn't create anything on Win32 due to caching */ I suppose Manuel wants GetTemporaryDirectory() to keep semantics similar mkdtemp(3). Though it is in

Hi. I'm attempting to compile Asterisk 12, but we want to use chan_sip instead of pjsip. I am missing something. I assumed that chan_sip was going to be added by default. Apparently not. I saw it in the menuconfig. Dumb question, but double xx beside It..does that mean not avail/not going to be installed? Can someone point me in the proper direction? A specific area where I can learn to

Hi, I'm officialy announcing the new 1.1.23 stable release of Samba Console, along with a stable IMC release too (1.2.24). This code is just going in production at a new customer site this week. From the project web site : Samba Console <http://imc.sourceforge.net/samba/index.html> is the first console developped for IMC. It offers a simple and ergonomic interface for managing a

Hi, I'm not sure if this is a libclang, llvm::cl or clang-interpreter issue so I'll try posting here for a response. I am using libclang as a frontend to the LLVM JIT (3.3 release). I started from the clang-interpreter example and have everything working (given a C/C++ source file I can have it JIT'd to memory and executed) for a single run. When I try to compile a second source

Oh, so it looks like I hit a bit of a wall there :-) I’ll take a look thanks. That bug talks about R_ARM_THM_CALL which I assume are thumb related.
