Cannot find -lsgx_tstdcxx
bsdinis opened this issue · comments
I have Intel-SGX and the drivers installed on my linux machine
However, I don't have libsgx_tstdcxx, but I have libsgx_tcxx.
If I make that change, though, the loader doesn't find any reference to __explicit_bzero_chk.
Is there anything I need to correct?
System Details
Thinkpad L460
$ uname -a
Linux althea 5.2.8-200.fc30.x86_64 #1 SMP Sat Aug 10 13:21:39 UTC 2019 x86_64 x86_64 x86_64 GNU/LinuxAccording to the Intel SGX Developer Reference, libsgx_tstdcxx is deprecated and should be replaced by libsgx_tcxx.
So the problem is the __explicit_bzero_chk.
Not sure how to solve
Hi
We are aware of several problems related to newer versions of the SDK and gcc.
One idea (to be tried) is maybe to replace the call to bzero() by a call to memset().
Please feel free to submit a pull request if you happen to solve the issue.
OK, another thing I have noticed is the use of -Wall and -Werror in production.
This is, in general, a bad practice, as it makes it harder for users to compile (especially with newer compiler versions); I'm going at it right now, I'll get back if find a solution
TaLoS is a research prototype. This is not production code.
Besides, -Wall -Werror allowed use to find and fix in advance several problems.
Fair enough, I mentioned production code as a proxy for "client" code, ie code to be compiled by users and not developers.
As an aside, do you have a roadmap for a production ready version (or integration in sgxssl) ?
There is no roadmap for TaLoS. The authors of TaLoS either changed institution or are working on different projects.
Nevertheless I am trying to address the issues when I have time.
