[LLVMdev] LLVM 1.4 Build Error

[Henrik Bach]

The HAVE_MMAP_FILE macro comes from when you configured llvm. The configure 
tested if your system is giving access to a various resources required by 
llvm. LLVM needs the MMAP functionality by your system. Some times, if the 
required resources aren't present, we use other resources.

However, in this case the building process is stopped, because the 
functionality can't be implemented by other means.

I really can't tell if RedHat 9.0 has MMAP present, but it makes me wonder.

What does your config.log tell you about MMAP? Please snip the relevant 
parts.


Henrik.

P.S. Can't your email system use ascii instead? I'm not able to import your 
question automatically into my system on reply.

I checked the source code and find this is caused by the undefined 
"HAVE_MMAP_FILE" macro. But I don't know what this macro is used for? How to 
sovle it?
thanks.
