Hello,
A while back, someone posted a question about the error:
/usr/include/libguile/scmconfig-64.h:83: error: ‘long long long’
is too long for GCC
but no fix was posted. I ran into this issue and am posting my
resolution in case anyone else runs into it.
I'm running Fedora 10 x86_64 with guile 1.8.5 and HDF5 1.8.1.
HDF5 /usr/include/H5public.h near line 127 has:
#if H5_SIZEOF_LONG_LONG>0
# define long_long long long
... snip ...
#endif
which is still present in the latest 1.8.2 release.
Guile /usr/include/libguile/scmconfig-64.h near line 83 has:
typedef long long long_long;
I tracked the origin of this line to gen-scmconfig.c, line 287 and it
is present in the recent 1.8.6 release.
If HDF5 is loaded before guile, the typedef becomes:
typedef long long long long
which confuses gcc (and me). As a temporary fix, I added:
#undef long_long
just before the typedef in scmconfig-64. It's not an elegant solution
but it works.
The HDF5 folks said they'd think about fixing this:

Hello Mark,
I checked with the developers on this. They said the
long_long hack was added to the code to pacify Windows compilers.
However, it looks like it may no longer be needed, as Visual Studio
2003/.NET, 2005, and 2008 say they support it now.
I'll enter a bug report for us to investigate and remove this from
HDF5.
Thanks!
