Hi,

I try also in my Ubunux box (12.04) with clang 3.0 ( Ubuntu clang version
3.0-6ubuntu3 (tags/RELEASE_30/final) (based on LLVM 3.0) Target:
x86_64-pc-linux-gnu Thread model: posix )

and i have the following error when i try to build with clang :

[  4%] Building C object wiretap/CMakeFiles/wiretap.dir/file_wrappers.c.o
/home/alagoutte/wireshark2/wiretap/file_wrappers.c:818:13: error: implicit
conversion loses integer precision:
      '__blksize_t' (aka 'long') to 'int' [-Werror,-Wshorten-64-to-32]
                want = st.st_blksize;
                     ~ ~~~^~~~~~~~~~

Have also for all file the following warning...
warning: unknown warning option '-Wpragmas' [-Wunknown-warning-option]
