I've just come across a subtle build issue (as haskell-platform just
got updated, I thought I might give it a try) The scenario is
* OSX 10.7 (everything is up to date with xcode etc... the usual)
* The 32bit version of Haskell Platform 2012.2
The issue is when libdiskfree.c is compiled and linked to git-annex,
OSX defaults to a 64bit binary, thus...
Linking git-annex ...
ld: warning: ignoring file Utility/libdiskfree.o, file was built for unsupported file format which is not the architecture being linked (i386)
Undefined symbols for architecture i386:
"_diskfree", referenced from:
_UtilityziDiskFree_zdwa_info in DiskFree.o
ld: symbol(s) not found for architecture i386
collect2: ld returned 1 exit status
make: *** [git-annex] Error 1
You can either compile up the c library in a 32bit mode if you have the 32bit
version of Haskell Platform installed as in the following example
laplace:git-annex jtang$ cc -m32 -c -o Utility/libdiskfree.o Utility/libdiskfree.c
Utility/libdiskfree.c: In function ‘diskfree’:
Utility/libdiskfree.c:61: warning: ‘statfs64’ is deprecated (declared at /usr/include/sys/mount.h:379)
laplace:git-annex jtang$ make
ghc -O2 -Wall -ignore-package monads-fd -outputdir tmp -IUtility -DWITH_S3 --make git-annex Utility/libdiskfree.o
Utility/Touch.hs:1:12:
Warning: -#include and INCLUDE pragmas are deprecated: They no longer have any effect
Utility/Touch.hs:2:12:

Utility/Touch.hs:3:12:

Utility/Touch.hs:4:12:

Linking git-annex ...
Or else just install the 64bit haskell platform. I'm not too sure where
you would but the intelligence to detect 32 or 64 outputs from the
different compilers. I suspect checking what ghc outputs then putting in
the appropriate -m32 or -m64 for the c compiler is the right thing to do.
Or just telling users to use the 64bit version of the haskell platform?
It may also be possible to get osx's c compiler to output a universal binary
to give you everything, but that be going down the _being too platform
specific route_.
> [[done]], it'll detect this and force -m32. --[[Joey]]
