Dear llvm,
I just tried to compile a simple file hello.c. But each time I used
llvmgcc hello.c, it gave me the following error:
xli3|csil-suna33|~/cs426|[13]% llvmgcc hello.c
as: error opening '/var/tmp//ccapglpE.o': file exists!
Use -f command line argument to force output
I really got confused. Could you please let me know what's wrong?
thanks,
Jerry

First try doing an 'rm -f /var/tmp/*' and try again. If that still
doesn't work, please post the output of: 'llvmgcc hello.c -v'
It may be possible that the wrong 'as' is installed on CSIL. llvmgcc
should print out a path to an 'as' utility as part of the -v output. If
you can figure out where it is, please post the results of 'as -v' where
the as invoked is the same one GCC is running. If this doesn't make
sense, just post the 'llvmgcc -v' output and I'll help you from there...
Thanks,
-Chris
Thanks, Chris,
Below is the output of 'llvmgcc he.c -v'

I think the as is the following one:
/home/vadve/lattner/cvs/gcc_install_sparc/bin/llvm-as
But actually, this path DOESN'T exist. I don't know why is that, please
help with that. Thanks a lot.

The problem with llvmgcc invoking as instead of llvm-as has been fixed.
3 llvm-specific executables needed to be copied into a default location
where gcc can find them if it does not find them as configured (gcc was
configured for the paths on our research machines and copied over). Let
us know if you have additional problems.

Dear Prof. Adve,
Now I can use llvmgcc to compile a .c file into .bc file. But I still have
trouble simply run the .bc code. Below is the sequence I got when I tried.
I really don't know what's going on here. Please let me know how can I fix
it.
Thanks,

lli on the CSIL machines has a problem which has been fixed on our
research machines. I'm planning to update the CSIL tree today.
