CGAL users discussion list

[Iordan Iordanov <>]

Hello all,

I have another problem related to this thread. Since last sime,
I was able to compile CGAL with LEDA, however I am unable to 
compile any simple program using LEDA from CGAL. I tried to 
investigate, but without positive results.

Please find attached to this message the output produced by make.

I should mention that initially I thought that I was using LEDA
incorrectly. I tried to compile the test leda_real in the package
Number_types, and I get the _same_ errors. In fact, I get the same
errors for any LEDA-related tests.
On the other hand, I tried compiling the tests/examples shipped
with LEDA itself, and it works just fine.
I have installed LEDA in the system folders, so I want to believe
there is no doubt that it is being detected, cmake confirms this.

Thank you,
