Subject: [Help-gsl] Building gsl-1.15 under MinGW
Hi all,
I'm trying to build gsl-1.15 under MinGW and are having some problems.
I was following the instructions from INSTALL.
After running ./configure and make the compiler stops at infnan.c with the
following error message:
infnan.c:98:3: error: #error "cannot define gsl_finite without
HAVE_DECL_FINITE or HAVE_IEEE_COMPARISONS"
infnan.c:115:3: error: #error "cannot define gsl_isnan without
HAVE_DECL_ISNAN or HAVE_IEEE_COMPARISONS"
========================================
Rather strange. When I build with MinGW (gcc-3.4.5) in my msys shell,
there's no problem.
A diff on our configure outputs is attached (the '-' is what the OP had, the
'+' is what I had). Perhaps that rings a bell for someone here .... doesn't
ring any bells for me, but :-)
Perhaps of more siginificance is the contents of (the generated)
gsl-1.15/config.h. You should be able to find the following line in that
file:
#define HAVE_DECL_FINITE 1
And you should also be able to find this line:
#define HAVE_IEEE_COMPARISONS 1
Does your gsl-1.15/config.h contain those lines ? (Your configure output
suggests that you should at least have the first.)
What does 'gcc -v' output for you ?
Cheers,
Rob
