Config.log after running export CC="gcc -lm" ; ./configure --with-long-double ;

I am using archlinux, a rolling-release distribution, and so the last versions of GCC and autotools is meant to be used when compiling.

I just downloaded the tarball from this link : http://ftp.gnome.org/pub/GNOME/sources/gnumeric/1.12/gnumeric-1.12.3.tar.xz

I extracted it and ran the configure script by doing :


cd ~/src/
wget http://ftp.gnome.org/pub/GNOME/sources/gnumeric/1.12/gnumeric-1.12.3.tar.xz
xz -d gnumeric-1.12.3.tar.xz ; 
tar xvf gnumeric-1.12.3.tar ; 
cd gnumeric-1.12.3 ; 
./configure --with-long-double ;

The script ends up failing with the two following lines :

checking for lgamma_r... no
checking for lgamma_r in -lm... yes
checking for lgamma... yes
checking sunmath.h usability... no
checking sunmath.h presence... no
checking for sunmath.h... no
checking for go_render_generall... yes
checking for fabsl... no
configure: error: Long doubles require the  function.

This is solved if one does before running the configure script by doing :

export CC="gcc -lm" ; ./configure --with-long-double ;
