Re: [Orclib-devel] trouble building the C++ example code

[vincent r. <vin...@gm...>]

Hi,

I got really busy and only found time for setuping clang on my box. I will
start testing clang tomorrow.
Could send me the complete gcc 4.3.6 failing build error log ?
And also the clang one ? The clamng error you pasted in your mail is weird
as it is like it does not see the class operator overload....

Regards,

Vincent
