 |
|
I'm working on making a JVMTI client just to get a bit of experience with it but visual studio is starting to beat me here.
So this will compile perfectly fine however if I try to add another function it's like my headers are broken and all the defines from jni like jint and JNICALL are not valid types anymore.
| Code: | #include <jvmti.h>
#include <iostream>
using namespace std;
JNIEXPORT jint JNICALL Agent_OnLoad(JavaVM *jvm, char *options, void *reserved)
{
cout << "AgentLoading..." << endl;
return JNI_OK;
} |
This is all I do to break it...
| Code: | #include <jvmti.h>
#include <iostream>
using namespace std;
JNIEXPORT jint JNICALL Agent_OnLoad(JavaVM *jvm, char *options, void *reserved)
{
cout << "AgentLoading..." << endl;
return JNI_OK;
}
JNICALL jint objectCallback(jlong class_tag, jlong size, jlong* tag_ptr, jint length, void* user_data)
{
return JVMTI_VISIT_OBJECTS;
} |
errors are like..
variable "jint" is not a type name
JNICALL error - this declaration has to storage class or type specifier

| This is for sure some random setting in VS as it works fine in code blocks.

jint appears to be a custom type implemented by the JavaVM code, probably just a typedef to a normal int such as:
For VS to error saying its not a valid type, there would need to either be a missing include somewhere that defines this type, or there are missing #defines needed to ensure the proper compiling settings are being enabled in the various Java headers.
