When I use SGX SDK to sign enclave.so,an error happened:

<EnclaveConfiguration>
<ProdID>0</ProdID>
<ISVSVN>0</ISVSVN>
<StackMaxSize>0x40000</StackMaxSize>
<HeapMaxSize>0x100000</HeapMaxSize>
<TCSNum>10</TCSNum>
<TCSPolicy>1</TCSPolicy>

<DisableDebug>0</DisableDebug>
<MiscSelect>0</MiscSelect>
<MiscMask>0xFFFFFFFF</MiscMask>
</EnclaveConfiguration>
[check_symbol_table elfparser.cpp:228] symbol 'memset' is undefined
The input enclave file is not correct.
Error happened while signing the enclave.

it shows symbol 'memset' is undefined,Did I miss something when compile the enclave?

Hi:

To find out the reason, you may need to share your make file. Maybe you linked the wrong dynamic library, check your enclave link option carefully .

you

Yes,You are right,The reason

Yes,You are right,The reason is I am not link some static libraries,so it can't generate the right .so file,and the sign tool can't sign it,now I link the libraries,it works!

Hi,

I need to use the glib-2.0 library in a program. So, I've tried to link the required library. However, I got an error that the functions used in my code (which are defined in glib-2.0 library) are not defined. Something like the following error.

LINK => nnenc.so

[check_symbol_table elfparser.cpp:231] symbol 'g_byte_array_set_size' is undefined

My makefile looks like the following (plus the SGX flags, because I just put the extra flags here):

Nnenc_Link_Flags := -lgmp \ -lpbc \ -lbswabe \ -lcrypto -lgmp\ -L/usr/local/lib -lpbc\ -Wl,-Bdynamic -L /usr/lib/x86_64-linux-gnu -lglib-2.0

It is worth mentioning that I have tried the following options as well and I got the same error.

Nnenc_Link_Flags := -lgmp \ -lpbc \ -lbswabe \ -lcrypto -lgmp\ -L/usr/local/lib -lpbc\ -L/usr/lib/x86_64-linux-gnu -lglib-2.0

I do not know what is wrong with my linker because I included the required headers and libraries.

Would you please let me know how can I solve this problem.
