I am using LLVM 2.5 release, together with llvm-gcc4.2-2.5.<br>
For the hello.c demo testing found close to the end of the
GettingStarted document:<br>
<br>
#include <stdio.h><br>
<br>
int main() {<br>
printf("hello world\n");<br>
return 0;<br>
}<br>
<br>
Following the instructions:<br>
obtaining the bc file: <i>llvm-gcc -O3 -emit-llvm hello.c -c -o
hello.bc</i><br>
running through lli: <b> </b><i>lli hello.bc</i><br>
<br>
I got this error msg: <i><b>ERROR: Program used external function
'puts' which could not be resolved! Abort</b></i><br>
<br>
I think this might have to do with my LD_LIBRARY_PATH settings, thus
explicitly checked that it includes a path to libc,<br>
echo $LD_LIBRARY_PATH: <b><i>/lib:/usr/lib:/opt/llvm-2.5/lib:.:/home/czhao/suif/suif_1.3.0/i686-cygwin-cygwin/solib/</i></b><br>
<br>
<br>
How could I fix this WinXP/Cygwin only thing?<br>
<br>
I tried the same steps on a Debian4-i386 machine, everything works fine.<br>
<br>
<br>
Thank you very much<br>
<br>
