windows - Did gfortran drop svml support on Cygwin? -

-

i having trouble compiling fortran code on brand-new cygwin installation, can trace undefined references functions in intel svml (short vector math library) library.

specifically, getting errors of form

import_gamess.o:import_gamess.f90:(.text+0xb58b):  undefined reference `vmldpow2'

and function vmldpow2 part of svml library, shown here, pass option gfortran in makefile as

f90 = gfortran -m64 -msse2 -o3 -march=native -mtune=native -fopenmp \   -ffast-math -fassociative-math -freciprocal-math -ffinite-math-only \   -fno-signed-zeros -fno-trapping-math -msahf -mmovbe -mrecip \   -mveclibabi=svml -ftree-vectorize -fexternal-blas    -fblas-matmul-limit=50  -static

(i using libraries lapack , lblas.)

the file compiled fine on laptop, running cygwin 1.7.17 on windows 7. (this installed circa 2013-04-18; gfortran version there 4.5.3.) trying replicate installation on new desktop, running windows 7, , have installed cygwin 1.7.25. getting above errors on both 32-bit , 64-bit installs (running gfortran 4.7.3 , 4.8.1, respectively), new install of 64-bit cygwin on desktop. not getting errors on linux boot on same desktop, can't @ moment.

it clear me there either (a) broken link svml, or (b) missing parts of library, on newer cygwin installs. have searched extensively, best of ability, ways reinstate library, appears intrinsic part of gnu compiler. did gnu compiler, in fact, drop support library? if not, surmise need repair either library or files link it. in case, library available? files should repair , how?

i recognize, though, there distinct possibility i'm barking wrong tree , happy set straight on if that's case. should looking?

the site corresponding link gfortran 4.8.1 reads -mveclibabi: 

to use option, both -ftree-vectorize , -funsafe-math-optimizations  have enabled, , svml or acml abi-compatible library must  specified @ link time.

the same holds true versions 4.7.1 , 4.7.2.

my guess need have intel mkl installed (and environment set up) , link against it. additionally, need specify -funsafe-math-optimizations.

or, drop -mveclibabi=svml , use gfortran vectorizing intrinsics.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
