Hi,
I suspect you're using ghc on a win32 platform. ghc-win32 doesn't
presently support non-blocking I/O, hence the behaviour you're
seeing.

Hello,
I
am playing around with concurrency using ghc 5.02.2. What I’d like
to do is have a bunch of threads do something indefinitely, while one thread
monitors stdin for user input (the user input affects the behavior of the other
threads in some way). From the documenta

On Solaris, you can build GNU C++ either way; that is, to use shared
libraries or linked libraries. (In fact you can also build it to enable
both, and select one or the other at link time.) So, this is certainly
worth checking. The easiest way to check it is to run "ldd -r" on the
exe
Many platforms have the C++ runtime and the C++ standard library as a
static library (probably because the C++ ABI is not as stable as it
should be...). I think this applies to both Mac OS and to Windows
[mingw32], perhaps it's the same with Solaris.
If that is the case, it would explain the pro

We run Solaris + gcc 2.95.3. The exact error message looks like this:

What is the O/S and compiler? That the C++ new operator is not found is
very strange. Throw is another story, as throw doesn't appear in the
compiled code with some compilers.

I have occasional problems getting ghc-5.04.1 to compile a very large
source file with -O switched on. The source file is generated by
another tool, and is rather large at 25762 lines (2776340 bytes).
Without -O, the compilation goes normally, taking about 10 minutes or so.
With -O, the compiler

Thanks, that indeed solved the problem.
