Build error on Ubuntu 24.10

[hector-cao]

I have this build error on Ubuntu 24.10

sdk/Makefile.source

In the target:

  $(MAKE) -C tlibc/ -j$(shell nproc) 2> /dev/null                                                             

The build error:

time/strptime.c:92:1: error: type defaults to 'int' in declaration of 'DEF_WEAK' [-Wimplicit-int]
time/strptime.c:92:1: error: parameter names (without types) in function declaration [-Wdeclaration-missing-parameter-type]

1. You need to add the following lines to the macro DEF_WEAK in the file ./linux-sgx/sdk/tlibc/time/strptime.c

#if 0
DEF_WEAK(strptime);
#endif

2. To compile SGX SDK for linux, you also need to delete the options '-V -qversion -version' in the file ./linux-sgx/sdk/cpprt/linux/libunwind/configure (this file should be generated by running ./autogen.sh first)

for ac_option in --version -v -V -qversion -version; do (line 4799)
for ac_option in --version -v -V -qversion; do (line 5765)

3. Modify the file ./linux-sgx/psw/enclave_common/sgx_enclave_common.cpp to add the following header: #include

#include
#include
#include
#include "sgx_enclave_common.h"

4. Modify the file ./linux-sgx/psw/ae/aesm_service/source/CMakeLists.txt to make it compatible withh C++17 standard

set(CMAKE_CXX_STANDARD 17)
