Re: [Help-gsl] Compiling & Testing New Interpolation Type

[Jean-François Caron]

Make is the command that is failing.  I do the following:
 CC=/usr/bin/clang CFLAGS=-g ./configure --disable-shared 
--prefix=/Users/jfcaron/Projects/GSL/compiled
make

I use —disable-shared because the MacOS section of INSTALL recommends it, but 
removing it changes nothing.

Many things are compiled (with clang), and eventually I reach this error 
message:

I have read the INSTALL sections about MacOS and PPC platforms, but they don’t 
seem to be relevant to this issue.  The compilation error occurs while making 
the ieee-utils target, in the file fp-darwin.c.  It seems that something 
expects all MacOS hosts to still be PPC machines?  The ./configure step is able 
to figure it out:

checking build system type... i686-apple-darwin13.1.0

Here is the output of sw_vers and clang -v on my system:

address@hidden:~/Projects/GSL/gsl-1.6$ sw_vers
ProductName:    Mac OS X
ProductVersion: 10.9.2
BuildVersion:   13C64
address@hidden:~/Projects/GSL/gsl-1.6$ clang -v
Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
Target: x86_64-apple-darwin13.1.0
Thread model: posix

Thanks for the help so far.  Let me know if I should paste the entire configure 
& make logs, or if I can provide other information for figuring this out.
