Question

So here is the story. I have this device that uses Linux and more open source tools(btw its an ARM). And I was given the task of creating some magic cashier application with it.

I have done it and now my boss have made a new request. He wants me to make that stuff(the device) connect to a remote database(preferably Oracle). So thats what I started doing with the light version of oracle instant client. Everything is fine and cool until I ran my first hello world:

#include <occi.h>

using namespace oracle::occi;

int main(){
  Environment *env = Environment::createEnvironment();
  Connection *conn = env->createConnection("HR", "password");
  env->terminateConnection(conn);
  Environment::terminateEnvironment(env);
  return 0;
}

Linking against occi, clntsh, thread;
And setting the library search path, along other stuff to: “${workspace_loc:/OracleTest/instantclient_10_2}” that is the directory that holds my .so files;

Here is the compilation command:

ucfront-g++ -Wl,-elf2flt="r" -static -o OracleTest  ./main.o   -locci -lclntsh -lthread -L/usr/local/arm-elf/lib -L"C:\workspace\OracleTest\instantclient_10_2" -L/usr/local/fit-libs/lib

And here is the error:

/usr/local/arm-elf/bin/ld.real: cannot find -locci collect2: ld returned 1 exit status

And there are a few things that I would like to mention:

1- I’m running windows and compiling this for linux, the instant client version that I’ve downloaded is for linux x86(No Idea if that will work or if it could be the source of the problem).

2- I’m using a modified version of eclipse to develop, specific for that device.

3- I have no idea if I should move those Oracle libs to the device after the compilation, so if anyone could give me orientation on that, I would be very thankful.

TLDR: I wan’t to compile the above code but it fails to link, help, please!

EDIT:

To the two first answers, no I haven’t found any specific ARM libraries, I don’t think there are any.

Here is the link if anyone can find anything that resemble an ARM distribution I would be thankful.
There are two RISC distribution but I don’t know if they are compatible with ARM :

Instant Client for HP-UX PA-RISC (64-bit)
Instant Client for HP-UX PA-RISC (32-bit) 

Answer 1

If you do not have ARM versions of the Oracle library, you’re totally out of luck there and would need to get one (perhaps there is a free driver?) or implement the wire protocol manually.
