Any advice? If you can't even install a package with no dependencies except base, I think there's trouble: $ cabal install cmath Resolving dependencies... Configuring cmath-0.3...

That's a good guess based on the error messages - or math.h isn't in whatever paths we're looking in. What sort of system are you compiling this on? You could write a test C program using those functions, if you're familiar with your C tool-chain. Antoine

I had this problem with an updated archlinux 64bit. I ``fixed'' it forcing binutils to downgrade. pacman -Udd http://arm.konnichi.com/core/os/x86_64/binutils-2.20.1-4-x86_64.pkg.tar.xz cabal install cmath pacman -S binutils I'm also having a similar error with bindings-sc3 now, but it does not ``fix'' it.

Pathnames indicated it's OS X. My first question is whether the appropriate Xcode is installed, including the optional components (pre-Xcode 4, the "BSD" packages needed to compile most Unix software were optional). Note that Xcode 4 from the App Store actually puts an installer program in /Applications; that has to be run to actually install Xcode. -- brandon s allbery allbery.b@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms

If math.h wasn't in the paths at all, wouldn't I get an error about _every_ function being undefined?

[...] My first question is whether the appropriate Xcode is installed, including the optional components (pre-Xcode 4, the "BSD" packages needed to compile most Unix software were optional).

I really am not sure about whether I installed the BSD packages. I'd guess I did, but maybe not. How can I tell, and is there a simple remedy?

It's XCode 3.2.6. Also, I've got 20 copies of math.h on my hard drive, at least of couple of which feature definitions of "gamma," "isinf," etc. Thanks for your help! Tom

The problem isn't math.h; these are link errors, so it's /usr/lib/libm.dylib that is somehow wrong. I can't help with this too much as I'm on Lion so it's a symlink to libSystem.dylib (and if that's messed up, you don't even *boot* much less compile stuff). -- brandon s allbery allbery.b@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms

I've got some free time again so I'm returning to this problem. 2 important facts: - A test C program, using one of the "undefined" functions (isnan) compiles with GCC and runs - I went in by hand and temporarily replaced each version of math.h on my computer with a version that has the necessary functions defined. Cabal-install still failed with the same error. This makes it seem like cabal doesn't have access to _any_ math.h file, but if this were the case, wouldn't I get many more undefined-function errors than I do?

Unless you are using an older ghc with -fvia-C, is not used or useful. The modern -fasm codegen doesn't know what to do with C-level declarations. If your is using macros to define gamma as something else, you will need to find that something else or use a wrapper library. I note that OS X doesn't have a gamma(). There are lgamma() and tgamma() and variations thereon.

Hmm, that's true... I don't really understand how .hsc files are compiled, but isn't the "#include " in cmath done in the very standard FFI style?

What do you mean by OS X not having them? On my system (10.6), gamma() is defined (at least in math.h (well, at least the ones in /usr/include/architecture/i386/ and /Developer/SDKs/MacOSX10.6.sdk/usr/include/architecture/i386/)) Thanks for your help. Tom

7.0.4 has -fasm by default, but you can force -fvia-C still. With -fasm, the include files are not used afaik; since direct assembly code is created and not C code, a C include file is not useful.

I'm on 10.7, and I have no gamma(). I just checked the 10.6 SDK includes; it has extern double gamma ( double ); /* Legacy API: please use C99 tgamma() instead. */ so apparently it was deprecated and is now removed. -- brandon s allbery allbery.b@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms

cmath doesn't build now, but I successfully installed hsc3 (which depends on cmath) on my computer less than 6 months ago. Same CPU and OS version, but different ghc/HP, and possibly different XCode. Also: Some other packages which have the same FFI C-include style build fine on my machine. Some which even include math.h. For example: - strptime - mp3decoder So maybe it's not a problem involving not having -fvia-c? Tom On 4/19/12, Brandon Allbery wrote:

Also, is there a way that I could "short circuit" (in the "True || _ = True" sense) the whole process of fixing this? For example, cabal-install cmath on a machine with similar architecture and OS, break out my SICP [0], and try to replicate cabal's storage methods by hand?
