It shows error message Cannot create OCI environment in my Visual c++ -


i using microsoft visualstudio2015, trying run c++ program using oci functions, program terminating.

i set ocilib path in visual studio , starting successfully, got message initialising failed in log file

#include "ocilib.h"        ofstream logfile;         logfile.open("logfile.txt"); void err_handler(oci_error *err) { if(oci_errorgettype(err) == oci_err_oracle) { const mtext* sql =oci_getsql(oci_errorgetstatement(err)); if(sql != null) {   logfile<<"error - sql : "<<sql<<"\n"; } }  logfile<<"error - msg : "<<oci_errorgetstring(err)<<endl; ++nbr_error; }   if(!oci_initialize(err_handler, null, oci_env_default)) {  logfile<<"error - initialise failed\n";  exit(1); }

after running program shows error - msg: cannot create oci environment program terminating,

what supposed do.

download instantclient-basic , instantclient-sdk-windows http://www.oracle.com/technetwork/cn/topics/winsoft-085727.html.

you should choose x86 or x64 version based on program. , decompress , merge them 1 folder.

in program, oci_initialize(err_handler, the_folder, oci_env_default)
