I am hitting a gcc/fltk craziness, and I have no clue what to look for.
The attached example is extracted from octave configure log,
and I am almost sure that nor the test nor the fltk header
are changed at all recently.
The problem is that the enumerations in FL/Enumerations.H are using the
C++ style syntax, and the conftest source code has the '.c' extension,
so gcc treats it as C.
The C++ syntax for an enumeration is as follows:
enum EColours { eRed, eGreen, eBlue };
The C syntax for an enumeration is as follows:
typedef enum { eRed, eGreen, eBlue } EColours;
You have two options. Either patch FL/Enumerations.H to use the C syntax
(there are also a number of C++ style comments that you may have to
change). Or, change the test to write out a file with a '.cpp'
extension, invoke g++ and drop the -Wimplicit-function-declaration (as
this is not valid for C++).
Hope this helps,
Dave.
