java - How to link static library in jni? -

-

i have created header file "abc.h" declaration

int abc();

then, created .cpp file "abc.cpp" definition

int abc() {    return 0; }

now created static library libabc.a above files.

i have created helloworld android project. created jni folder in subfolders "header" , "src" in it. in header folder have put abc.h , in src folder have put "abc.cpp". have created file "xyz.cpp" in jni folder wants use abc() function. when run ndk-build command error. jni/jnimagiccleanmanager.cpp:84: error: undefined reference function abc (something this)

how definition of abc() static library libabc.a have put libabc.a in same folder parallel android.mk. following android.mk file

local_path := $(call my-dir) include $(clear_vars) magic_clean_root := .. magic_clean_src_root := ../$(local_path)/src magic_clean_src_files := xyz.cpp magic_clean_c_includes := $(local_path)/headers/  local_static_libraries := magicclean local_module := myjnilib2   local_src_files := $(magic_clean_src_files) local_c_includes := $(magic_clean_c_includes) local_c_includes += . include $(build_shared_library)

edit 1 : many asking why have abc.cpp when have static library, keeping code only. please tell how call function static library.

before use local_static_libraries need use prebuilt_static_library example, example uses gnu static lib, same yours.

include $(clear_vars)  local_module            := gnustl_static local_cppflags += -std=c++11 local_src_files         := ${ndk_root}/sources/cxx-stl/gnu-libstdc++/4.9/libs/armeabi/thumb/libgnustl_static.a local_export_c_includes := ${ndk_root}/sources/cxx-stl/gnu-libstdc++/4.9/libs/armeabi/include local_export_c_includes += ${ndk_root}/sources/cxx-stl/gnu-libstdc++/4.9/include/  include $(prebuilt_static_library)

you should put in android.mk

i'm trying plot frequency characteristic equation using ezplot, matlab gives following warning, "contour not rendered non-finite zdata". have used command plot frequency equations warning , plot display empty , not change axis range well. can please help. appreciated. here's code i'm using. % transfer matrix case-i, thin rotor clear all; clc; ei = 1626; l = 0.15; m = 0.44108; = 2.178*10^-4; i_p = 2.205*10^-5; itr = 0.24; i_pr = 0.479; syms p n; f = [1 l*1i l^2/(2*ei)*1i l^3/(6*ei); 0 1 l/ei -l^2/(2*ei)*1i; 0 0 1 -l*1i; 0 0 0 l]; p = [ 1 0 0 0; 0 1 0 0; 0 -it*p^2+i_p*n*p 1 0; -m*p^2 0 0 1]; p_r = [1 0 0 0; 0 1 0 0; 0 -itr*p^2+i_pr*n*p 1 0; -m*p^2 0 0 1]; = f*p*f*p*f*p*f; b = p_r*f*p*f*p*f; r = a(1,2)/a(1,4); a12_p = 0; a22_p = a(2,2)-r*a(2,4); a32_p = a(3,2)-r*a(3,4); a42_p = a(4,2)-r*a(4,4); ap(2,2) = a22_p; ap(3,2) = a32_p; ap(4,2) = a42_p; ap(4,4) = 1; c = b*ap; m = [c(3,2) c(3,4); c(4,2) c(4,...

i using indy udp server read string of data. however, not know how work adata parameter. can around converting binary using bytetobin function below , convert hex using bintohex1 . feel stupid , works slow. know how can directly results without 2 conversions? thanks!! here codes: procedure tform1.idudpserver1udpread(athread: tidudplistenerthread; const adata: tidbytes; abinding: tidsockethandle); var buf: tidbytes; buffer: string; data_received: string; begin if bytestostring(adata) <> 'hello' begin buffer := hextostring('00'); setlength(buf, length(buffer)); copytidstring(buffer, buf, 0); abinding.sendto(abinding.peerip, abinding.peerport, buf); data_received := bintohex1(bytetobin(adata[1]) + bytetobin(adata[2]) + bytetobin(adata[3]) + bytetobin(adata[4]) + bytetobin(adata[5]) + bytetobin(adata[6]) + bytetobin(adata[7]) + bytetobin(adata[8]) + bytetobin(adata[9]) + bytetobin(adata[10]) + bytetobin(adata[11...
