I am getting the following error for STL files on GCC 4.1.2. And the same code works properly without any compilation errors on GCC 3.4.6.
I am including some built-in headers in my code that in turn include these STL files. Hence, I cannot modify the header files.I compile it using the following:
gcc -I/grid/0/gs/java/jdk64/current/include -I/grid/0/gs/java/jdk64/current/include/linux -I/grid/0/tmp/direct/include/ydmg/ ydmg.cpp -I/grid/0/tmp/direct/include/ -o libydmg.so
Do I need to include some other parameter while compiling?
Could the compiler version be the cause of this problem?
The error is as follows:

Any help would be appreciated.
Here is the C++ code. I am calling the methods from ydmg and yut libraries using JNI. This code is working perfectly fine on gcc 3.4.6. Its gives errors on gcc 4.1.2.
#include <stdio.h>
#include "ydmg/bd.h"
#include <jni.h>
#include "yut/string.h"
extern "C" int getAge();
JNIEXPORT jint JNICALL Java_ydmgBd_getAge(JNIEnv *, jobject)
{
ydmgBd bdObject;
yutString s = bdObject.getKeys();
printf("\ngetKeys() returns the key as : %s",s.c_str());
yutHash user;
yutString value = "abc";
yutString key ="login";
user.set(key,value);
ydmgBd bd1(user);
bool val = bd1.save(user);
if(val){
printf("\ntrue");
}else {
printf("\nfalse");
}
int age = bd1.getAge();
printf("\nAge : %d ",age);
printf("\nhi");
return 1;
}
int main(){
return 0;
}
If you compile cpp code with gcc
and not with g++
, you must link with -lstdc++
, so that option is definitely missing.
However, the problem already occurs at the parsing step, so my suggestion is to check the namespaces... e.g. have a look at the error output:
...
ytl::std::operator!=
...
std
should not be in your personal ytl
namespace. You are doing something wrong with your includes.
One of your header files is almost certainly including:
#include <vector>
Before that line, add:
#undef max
And I believe your compiles will start working. This is happening b/c you are also using the C std library, which for some functions uses macros, and in this case, causes the preprocessor to freak out. I've seen this same error on Linux, and undefining that symbol was all i needed to get things compiling again.
