Thanks, I've fixed this problem by manually define that macro in the
generated config file. My system does have the <b>mmap()</b> function.
It's just that configure didn't get the right result. Sorry for the
inconvenience.<span class="moz-smiley-s1"><span> :-) </span></span><br>

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.

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

<br>
I really can't tell if RedHat 9.0 has MMAP present, but it makes me
wonder.
<br>
<br>
What does your config.log tell you about MMAP? Please snip the relevant
parts.

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?
<br>
thanks.

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]: ***

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>
