It++ /cygwin error, help

[wavestar]

I use cywin try to link the it++ library.
My verstion: itpp_3.10.7
external lib: itpp_external_2.3.10
It seems to me that I have problems when lik the libcblas library.

Thanks a lot,

Thanks a lot, guys.
Yes, I changed the lib order. It works now
with Eclipse/cygwin/gcc.

Can I compiled the it++ with visual studuio C++ 2005 express and with ACML
in window platform, and run in Intel dual core?

Thanks a lot to share the knowlege.

Best,

Maybe the order of libraries in linking flags is incorrect? I remember that Cygwin is quite picky about such issue.
Please, try putting "-latlas -lf77blas" after "-llapack -lcblas".

BTW, IT++ 3.10.7 is quite outdated and not supported any longer (it means that it includes known bugs, which were fixed in later versions). Please consider upgrading to the latest stable release (4.0.3 at the time of writing this post).

BR,

You can link to the ACML 3.6.0 (GNUFortran) with Cygwin.
I also runs on my Intel CoreDuo, much faster than with the
BLAS reference library.
See my posting in the "Help" Forum.
