[bug-goptical] No executable

[Denis Royer]

Hi all,
After having downloaded the .tar.gz goptical and unzipped it, I came to 
the install procedure. The "sleep" problem has been overcome with the 
forum prescription (#include  <unistd.h> in two files). Now the 
./configure, make, sudo make install, seem to proceed without error, but 
finally I cannot find any executable (.svg ?). Is it produced ? Is it 
hidden somewhere ? How can I check for errors ?
Thanks for advice.
Denis
