Issues when compiling libvirt-1.2.0 #10

Closed ruigulala closed 8 years ago

ruigulala commented 8 years ago

Thanks for building and maintaining such good tool. I've encountered a problem when using wllvm to build libvirt-1.2.0 on a x86-64 machine. The building process is fine when using clang alone or gcc. Here is the command that I use: CFLAGS="-g -O0" CC=wllvm ./configure --without-udev --prefix=$HOME/Tools/libvirt make Here is the error output.

Thanks Rui, I'll take a look...

Rui,

I tried on Ubuntu 14.04.3 with a 3.4 tool chain and the puppy built just fine.

Is it the make that is giving you trouble or an extract-bc command?

Let me know if you want me to investigate further (with the 3.6 tool chain for example).

Cheers, Ian.

ruigulala commented 8 years ago

Thank you Ian for the investigation. Yeah, could you please try the 3.6 tool chain? I was using clang 3.6.1 when having this error.

ianamason commented 8 years ago

OK trying that now.

While I'm waiting for the configure ...

Is it the make that is giving you trouble or an extract-bc command?

ianamason commented 8 years ago

Sorry Rui, Same success story with the 3.6.2 tool chain.

ruigulala commented 8 years ago

Ok, I see. The error came out during the make process. Thanks. I think may be I'm having some mis-configuration issue. I'll look into it.
