Symbol name collision with pkcs11.h identifier CKM_RSA_AES_KEY_WRAP

[jepio]

Describe the bug
Building an application that includes both sdk/keyvault/azure-security-keyvault-keys/inc/azure/keyvault/keys/key_client_models.hpp and OASIS pkcs11.h fails due to both defining a symbol named CKM_RSA_AES_KEY_WRAP. Namespacing is irrelevant here, as pkcs11.h defines a macro.

Exception or Stack Trace
gcc compiler error:

In file included from /workspaces/azure_kms_pkcs11/pkcs11_compat.h:12,
                 from /workspaces/azure_kms_pkcs11/attributes.h:1,
                 from /workspaces/azure_kms_pkcs11/aws_kms_pkcs11.cpp:11:

To Reproduce

apt-get install gcc g++ p11-kit libp11-kit-dev
g++ -c snippet.cpp -I/usr/include/p11-kit-1/p11-kit -I<path to azure-sdk-for-cpp>

Code Snippet
Add the code snippet that causes the issue.

#include <pkcs11.h>
#include <azure/keyvault/keys/key_client_models.hpp>

Expected behavior
pkcs11 and Azure sdk can be used in the same compilation unit.

Thank you for submitting this issue. Looking into it .

[gearama]

as a temporary workaround reverse the includes

#include <azure/keyvault/keys/key_client_models.hpp>
#include <pkcs11.h>

Also you might need to call the macro as such KeyEncryptionAlgorithm::(CKM_RSA_AES_KEY_WRAP) – taking macro in braces disables macro expansion.
