Did you read

IIRC this error happens if you use ccache and you don't set CCACHE_CPP2.


I set it, the first two lines of my configure script helper look like:

export CCACHE_CPP2=1
./autogen.sh CC=clang CXX=clang++ \

Thanks.

Smells like compile-step specific -I switches are passed into a compiler 
invocation that ultimately just causes a link-step.  I'd try to get 
better information about what commands are actually invoked by the build 
(something like "make libwpd verbose=1") and figure out from there 
(might be an autotools issue?; building libwpd involves the dreaded 
libtool AFAIK).  I cannot reproduce here (Fedora 22, recent Clang trunk 
build).

And it works without ccache?

Without ccache works all right.
Though:

$ ccache -V
ccache version 3.1.11

I guess I have something wrong with it.
FTTB I'll work without ccache.

Thanks for the help.

Depending on how you invoke your configure-script helper, that might
only be valid for while your configure script runs, and not when you
later call make.

PS: also use CCACHE_HARDLINK=1 - not only does that save a little
diskspace, it also should be a tiny bit faster.

Compiling with clang 3.7: breaks in 'external/libwpd'

2015-10-10 Thread Giuseppe Castagno 

Hi all,

I'm trying to compile with clang 3.7 (home built from source I got as 
described here [1]) on Ubuntu 14.04.


Building LO master f99743e from scratch breaks as:

...

Making all in lib
  CXX  libwpd_internal.lo
clang: error: argument unused during compilation: '-I .'
clang: error: argument unused during compilation: '-I ../..'

Compilation exited abnormally with code 2 at Sat Oct 10 11:20:08
...

Configured as:

CC=clang
CXX=clang++
--with-external-tar=/srv5/git/LO/externals
--with-lang=en-US
--enable-compiler-plugins
--enable-sal-log
--with-parallelism=1

single core build log of broken project can be read from
http://pastebin.com/QgMyzkJt

Any Idea?

Thanks
