About getenv() on OSX - c++

Question

I need to get the value of the environment variable ANDROID_HOME on OSX (set in .bash_profile). I can verify its existence by typing echo $ANDROID_HOME in the terminal.
Here is the code: (Xcode project)
void testGetEnv(const string envName) {
char* pEnv;
pEnv = getenv(envName.c_str());
if (pEnv!=NULL) {
cout<< "The " << envName << " is: " << pEnv << endl;
} else {
cout<< "The " << envName << " is NOT set."<< endl;
}
}
int main() {
testGetEnv("ANDROID_HOME");
}
The output is always The ANDROID_HOME is NOT set.. I don't think I'm using getenv() correctly here. Either that, or .bash_profile is not in effect when the getenv() is called.
What am I missing?

Your code seems correct - so you're most probably calling your program in an environment where ANDROID_HOME is indeed not set. How are you starting your program?
I changed your source code to actually be compilable, and it works fine on my OS X system:
#include <iostream>
#include <string>
#include <stdlib.h>
using namespace std;
void testGetEnv(const string envName) {
char* pEnv;
pEnv = getenv(envName.c_str());
if (pEnv!=NULL) {
cout<< "The " << envName << " is: " << pEnv << endl;
} else {
cout<< "The " << envName << " is NOT set."<< endl;
}
}
int main() {
testGetEnv("ANDROID_HOME");
}
Compile that with:
g++ getenv.cpp -o getenv
Now run:
./getenv
The ANDROID_HOME is NOT set.
export ANDROID_HOME=something
./getenv
The ANDROID_HOME is: something
