[LLVMdev] LLVM Cygwin build RLIMIT_RSS configuration problem

There seems to be a problem with the LLVM Cygwin configuration. Cygwin does not
support the RLIMIT_RSS symbol.

llvm[1]: Compiling Program.cpp for Debug build
/usr/src/llvm/lib/System/Unix/Program.inc: In function 'void
llvm::SetMemoryLimi
ts(unsigned int)':
/usr/src/llvm/lib/System/Unix/Program.inc:123: error: 'RLIMIT_RSS' was
not decla
red in this scope
make[1]: *** [/usr/build/llvm/lib/System/Debug/Program.o] Error 1
make[1]: Leaving directory `/usr/build/llvm/lib/System'
make: *** [all] Error 1

I am not really up on LLVM configuration otherwise I would look into the problem
myself.

[LLVMdev] LLVM Cygwin build RLIMIT_RSS configuration problem

This may well actually be a problem with the Cygwin getgid() function.

[LLVMdev] LLVM Cygwin build RLIMIT_RSS configuration problem

In order to get Cygwin working there is a need to add a HAVE_RLIMIT_RSS and
associated logic.

Hi Aaaron,

This was just recently added. Does cygwin even have getrlimit and
setrlimit?  IIRC correctly, it doesn't. So, perhaps these functions need
to be written differently for Cygwin. What's the equivalent win32 call?

If cygwin does have getrlimit/setrlimit then we'll have to figure out
what RLIMIT_RSS should be under cygwin. Is there the notion of running
set size under cygwin?

Reid.

[LLVMdev] LLVM Cygwin build RLIMIT_RSS configuration problem

Hello, Reid.
> to be written differently for Cygwin. What's the equivalent win32 call?I can be wrong, but there is no direct equivalent in WinAPI. AFAIK,
there are only few possibilities to set such limits on "pure" win32
subsystem.
