Error in template usage when compiling with Sun Studio 12 and stlport4

[Dagobert Michelsen]

Hi,

when I try to compile xapian-core 1.2.13 on Solaris 10 Sparc with Sun Studio 12 I get the following template compilation error:

I guess we'll have to construct a temporary qp_flag instead of just overloading operator< here.

Can you try the attached patch, please?

[Dagobert Michelsen]

I can confirm that the test works. Now I have several failing tests. I will open another ticket for that. Thanks again for the patch!

[Dagobert Michelsen]

I meant "I can confirm that the patch works". The source now compiles cleanly on Sun Studio 12.

Thanks for testing - committed to trunk (for 1.3.1) in r17048 and for 1.2.14 in r17050.
