apachelogger ScottK: that cmake bug looks like fun btw
apachelogger also I do not think it is a cmake issue at all
apachelogger or perhaps it is, but only partially
apachelogger in particular it is probably falling over the fact that cxx has
a cmd and a arg, which generally speaking of course is a bit of a bogus
situation
apachelogger yeah
apachelogger gcc got three args with -d
apachelogger cmake does not call either
-*- apachelogger runs cmake with tracing
apachelogger /usr/share/cmake-2.8/Modules/Platform/UnixPaths.cmake(32):
EXECUTE_PROCESS(COMMAND dpkg-architecture -qDEB_HOST_MULTIARCH OUTPUT_VARIABLE
CMAKE_ARCH_TRIPLET OUTPUT_STRIP_TRAILING_WHITESPACE )
apacheloggerCalled from: [4]
/usr/share/cmake-2.8/Modules/Platform/UnixPaths.cmake
apachelogger [3]
/usr/share/cmake-2.8/Modules/Platform/Linux.cmake
apachelogger [2]
/usr/share/cmake-2.8/Modules/CMakeSystemSpecificInformation.cmake
apachelogger [1]
/home/me/src/git/libechonest/CMakeLists.txt
apachelogger /usr/bin/ccache: invalid option -- 'd'
apachelogger 5 bucks that call comes from a patch
apachelogger me@osiris:/tmp/cmake-2.8.4+dfsg.1$ grep -ri dpkg-architecture .
apachelogger
./debian/patches/ubuntu_multiarch_library_directory.diff:+EXECUTE_PROCESS(COMMAND
dpkg-architecture -qDEB_HOST_MULTIARCH OUTPUT_VARIABLE CMAKE_ARCH_TRIPLET
OUTPUT_STRIP_TRAILING_WHITESPACE)
debfx what's wrong with it?
apachelogger well, it causes ccache -dumpmachine to be called
apachelogger leading to an eror in ccache
apachelogger as obviously the call should be ccache gcc -dumpinfo
apachelogger eh
apachelogger dumpmachine
apachelogger debfx: perhaps the patch was applied differently upstream?
debfx how does ccache hook into the buildsystem? does it modify $PATH?
apachelogger no
apachelogger you set a new CXX and CC env var
apachelogger debfx: multiarch is something gcc, that should totally be
implemented in cmake upstream
apachelogger anyhow
apachelogger for some reason dpkg-architecture calls:
apachelogger execve(/bin/sh, [sh, -c, ${CC:-gcc} -dumpmachine], [/*
50 vars */]) = 0
apachelogger resulting in
apachelogger execve(/usr/bin/ccache, [/usr/bin/ccache, -dumpmachine],
[/* 50 vars */]) = 0
apachelogger which then produces crap outs
apachelogger I believe cmake pokes the env around a bit
apachelogger I know that it definitely stores CC/CXX as a combo of command +
argN
apachelogger so if cmake were to set its envrionemnt so that CC only contains
the command and no the arg (which is generally sane behaviour I suppose), that
would screw over the poor old dpkg-architecture
