Hello,<br>

 I built llvm1.4 with gcc3.4.3 and glibc2.3.2 on a redhat 9.0 machine,

but got this error:<br>

<small>/home/zhoufeng/bin/llvm/llvm-build/../llvm/lib/Support/FileUtilities.cpp:299:2:

#error Unimplemented ReadFileIntoAddressSpace - need to use read/write.<br>

gmake[1]: ***

[/home/zhoufeng/bin/llvm/llvm-build/lib/Support/Debug/FileUtilities.o]

Error 1<br>

gmake[1]: *** Waiting for unfinished jobs....<br>

gmake[1]: Leaving directory

`/home/zhoufeng/bin/llvm/llvm-build/lib/Support'<br>

gmake: *** [all] Error 1<br>

</small>I checked the source code and find this is caused by the

undefined "<b>HAVE_MMAP_FILE</b>" macro. But I don't know what this

macro is used for? How to sovle it? <br>

thanks.<br>
