如何使用IDC或IDAPython获取当前IDA Pro版本？

Great question—handling version-specific function differences in IDA is super common, and grabbing the current version is the first step to making your scripts cross-compatible. Here's how to do it with both IDC and IDAPython:

IDC provides a straightforward function to get the IDA version as a human-readable string. Use GetIdaVersion():

// Retrieve the version string (e.g., "7.7", "8.0")
auto ida_version = GetIdaVersion();
// Print the result to IDA's message window
Message("Current IDA Version: %s\n", ida_version);

If you need to compare versions numerically, you can parse the string into major/minor components using standard IDC string functions like strtok or atoi.

IDAPython offers two convenient options depending on whether you want a readable string or a machine-friendly numeric format:

Option 1: Get version as a string #

Use idaapi.get_version() to fetch the version string directly:

import idaapi

version_str = idaapi.get_version()
print(f"Current IDA Version: {version_str}")

Option 2: Get version as a numeric tuple #

For easier version comparisons (great for branching logic), use idaapi.get_kernel_version() which returns a tuple of (major, minor, revision):

import idaapi

major, minor, rev = idaapi.get_kernel_version()
print(f"IDA Version: {major}.{minor}.{rev}")

Once you have the version data, you can branch your code to use the correct function names for each IDA release. For example, in IDAPython:

import idaapi

major, minor, _ = idaapi.get_kernel_version()

# Check if running IDA 7.6 or newer
if major >= 7 and minor >= 6:
    # Use the updated function name for newer versions
    idaapi.new_version_function()
else:
    # Fall back to the older function name for legacy versions
    idaapi.old_version_function()
