Hi,
We are happy using ccache with clang but I just discovered today that
ccache hides documentation warnings!
I am using clang 3.7.1, ccache 3.2.4.
/opt/clang-3.7/bin/clang++ --version
clang version 3.7.1 (tags/RELEASE_371/final)
Target: x86_64-unknown-linux-gnu
Thread model: posix
ccache --version
ccache version 3.2.4
Here is a small function file (foo.cc) with wrong doxygen documentation.
If I compile directly with clang++ I have 3 warnings:
===================================================================
/opt/clang-3.7/bin/clang++ -Weverything -c foo.cc
foo.cc:7:5: warning: '\return' command used in a comment that is
attached to a function returning void [-Wdocumentation]
* \return true there is no return value... 2nd warning
~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
foo.cc:5:11: warning: parameter 'pThis' not found in the function
declaration [-Wdocumentation]
* \param pThis there is no such param... 1st warning...
^~~~~
foo.cc:10:6: warning: no previous prototype for function 'foo'
[-Wmissing-prototypes]
void foo(){}
^
===================================================================
ok, so far so good...
But if I compile it with ccache, the 2 warnings about documentation are
disappearing:
ccache /opt/clang-3.7/bin/clang++ -Weverything -c foo.cc
foo.cc:10:6: warning: no previous prototype for function 'foo'
[-Wmissing-prototypes]
void foo(){}
My CC* environment variables:
CCACHE_SLOPPINESS=include_file_mtime
CCACHE_DIR=/home/ccache/cmpbib/ccache
CCACHE_CPP2=yes
CCACHE_HARDLINK=1
CCACHE_HASHDIR=
How can I retrieve the documentation warnings with ccache? Do I do
something wrong?
Thanks,
Eric
