[LLVMdev] [Cygwin] 'make tools-only' configuration error

[Aaron Gray]

I did not report this first error earlier as I thought it trivial.

Basically it looks like something odd is happening with the configuration and 'include/llvm/config/config.h'

Getting this error on building the tools on a fresh Cygwin install and update :-

$ make tools-only
make[1]: Entering directory `/usr/build/llvm/lib/System'
llvm[1]: Compiling Path.cpp for Debug build
In file included from /usr/src/llvm/lib/System/Path.cpp:104:

sys::Path llvm::sys::Path::GetTemporaryDirectory()':

e this function)
/usr/src/llvm/lib/System/Unix/Path.inc:93: error: (Each undeclared identifier is

make[1]: *** [/usr/build/llvm/lib/System/Debug/Path.o] Error 1
make[1]: Leaving directory `/usr/build/llvm/lib/System'
make: *** [all] Error 1

On commenting out the "#define HAVE_MKDTEMP 1" this error is bypassed, but what is leading to this error ?

This happens on a new fresh install of Cygwin, GCC 3.4.3, binutils 2.15, and fresh llvm from CVS !

And it is repeatable. Either I am doing something basic wrong or there is an issue here, what I do not understand is why I did not run into it when we (Reid Spencer and myself) did the previous Cygwin debugging session.

It looks like the configure script is failing drastically, I am confused.

Still getting the previous error :-

Doing 'make tools-only ENABLE_OPTIMIZED=1 gives a simular but different error :-

I have gone back to the older Cygwin environment that worked before but am now getting the same results as with the newer Cygwin installation. Why it worked before but not now I do not know.

The first error in this mail does not occur with the older Cygwin installation.

The only thing I can think is it is my instillation proceedure but I cannot find anything wrong with it.
