Subject: [Rd] complex.h in R
Message-ID: <4335A2EA.1050000@lindaspaces.com>

Hi,
    How does complex.h used in R? Whether a compiler support complex.h 
or not, does it affect R's performance? I used PGI compiler to build 
R-devel on AMD Opteron, but the configuration file failed to link BLAS 
library despite the fact it is located in the usual location, 
/usr/lib64.  PGI said they don't support complex.h. R configuration 
script printed out that doublecomplex is not supported. Are "supporting 
complex.h" and "linking BLAS library" related?
any comments on this issue?

note: I can ignore linking BLAS and proceed to compile R with PGI 
compiler successfully.

Regards,
Jennifer
