c - link error in gsl_complex_mul -


i have started using gsl recenltly in huge old c project. have managed add libraries adding location in system in properties>c/c++>general>additional include directories.

in code, including following:

#include "gsl/gsl_matrix.h" #include "gsl/gsl_matrix_complex_double.h" #include "gsl/gsl_matrix_complex_float.h" #include "gsl/gsl_matrix_complex_long_double.h" #include "gsl/gsl_math.h" #include "gsl/gsl_spmatrix.h" #include "gsl/gsl_complex.h" #include "gsl/gsl_complex_math.h" #include "gsl/gsl_inline.h" #include "gsl/gsl_complex.h"

i can use functions of gsl. in fowllowing function:

void vector_complex_mul_elements(gsl_vector_complex *v1, gsl_vector_complex *v2) {     gsl_complex cpx1, cpx2, cpx3;     gsl_set_complex(&cpx1, 0, 0);     gsl_set_complex(&cpx2, 0, 0);     gsl_set_complex(&cpx3, 0, 0);      if(v1->size != v2->size)     {         printf("error: lenght of arrays not match.\n");         return;     }      for(i=0; < v1->size; i++)     {         cpx1 = gsl_vector_complex_get(v1, i);         cpx2 = gsl_vector_complex_get(v2, i);         //cpx3 = gsl_complex_mul(cpx1 , cpx2);         gsl_vector_complex_set(v1, i, cpx3);      } }

when uncomment line:

cpx3 = gsl_complex_mul(cpx1 , cpx2);

i following errors:

error lnk2001: unresolved external symbol "_log1p".

error lnk2001: unresolved external symbol "_log1p".

error lnk2001: unresolved external symbol "_hypot".

error lnk1120: 2 unresolved external references.

i have tried writing like:

gsl_vector_complex_set(v1, i, gsl_complex_mul(cpx1 , cpx2));

then these errors:

error lnk2019: reference unresolved external symbol "_log1p" in function "_gsl_complex_logabs".

error lnk2019: reference unresolved external symbol "_hypot" in function "_gsl_complex_div".

error lnk2001: unresolved external symbol "_log1p".

error lnk1120: 2 unresolved external references.

is linking problem or way using wrong?

these (lop1p , hypot) functions in standard maths library. including math.h , linking (-lm)? per gsl documentation.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
