Hi!
When I compile AmberTools 1.5 using gcc-4.6.1 under Ubuntu, it works fine.
However, when I compile using gcc-4.4.6, I get the error of : /usr/bin/ld: cannot find -lgfortran
The full error log is given below.
Regards,
Adam
Error log:
adam.adam-MS-7750:~/amber11/AmberTools/src$ ./configure gnu
Could not find the X11 libraries; you may need to edit config.h
to set the XHOME and XLIBS variables.
Warning: the X11 libraries are not in the usual location !
To search for them try the command: locate libXt
On new Fedora OS's install the libXt-devel libXext-devel
libX11-devel libICE-devel libSM-devel packages.
On old Fedora OS's install the xorg-x11-devel package.
On RedHat OS's install the XFree86-devel package.
On Ubuntu OS's install the xorg-dev package.
For the moment Amber will be configured not to build XLEaP.

You don't need to build AmberTools in order to build the cuda executables.
You just need to have AmberTools 1.5 extracted in the AMBER directory. Where
are you finding the gcc 4.6 requirement btw? - I have no issues building all
of AMBER 11 and AmberTools 1.5 using RedHat 6 and GCC 4.4.6 and NVCC 4.0.
All the best
Ross
