I also tried to compile things differently,
f95 -fno-second-underscore -c -fPIC pattern_dist.f90
gcc -std=gnu99 -shared -L/usr -o pattern_dist.so pattern_dist.o
now, I get the following error:
Error in dyn.load("~/myfortran/pattern_dist.so") :
unable to load shared library '/home/myfortran/pattern_dist.so':
/home/myfortran/pattern_dist.so: undefined symbol: _g95_section_info
Calls: source -> eval.with.vis -> eval.with.vis -> dyn.load
However, doing nm with the shared object name, shows up that symbol:
> nm ~/myfortran/pattern_dist.so | grep _g95_section_info
U _g95_section_info
Does anyone have an idea of what might be going on?
Thanks
