Not able to build the apps about sgx-step

[jovanbulck]

this is normally not an issue in SGX-Step, but indicates that you didn't set the environment for yr SGX-SDK installation properly. You should normally do source /opt/intel/sgxsdk/environment in the shell where you execute the Makefile

Hope this helps

Solved. turns out i didn't set the environment correctly.
although, i run into a different problem when using 'make run' in the 'foreshadow' folder:

Solved. i rebuild everything from the start.

Great, I'll close this issue. Sorry didn't see you troubles earlier.. These are indeed typical linker dependency problems fixed by setting the environment as described in the linux-sgx README :)

Hey, i'm currently trying to build the 'foreshadow' app but when i run the makefile i get this error:

[===] Enclave [===]
[GEN] sgx_edger8r encl.edl
make[1]: sgx_edger8r: Command not found
Makefile:84: recipe for target 'edger' failed
make[1]: *** [edger] Error 127
Makefile:72: recipe for target 'build-Enclave' failed
make: *** [build-Enclave] Error 2

I edited the makefile inside the 'Enclave' folder by:

• adding the line:
  SGX_SDK ?= /opt/intel/sgxsdk
  (when i tried to print the value of SGX_SDK through "echo" i got blank output).
• changing the EDGER variable to be
  EDGER = $(SGX_SDK)/bin/x64/sgx_edger8r

the error above seemed to be solved but then i encountered a new one:
[===] Enclave [===]
[GEN] /opt/intel/sgxsdk/bin/x64/sgx_edger8r encl.edl
[CC] encl_t.c (trusted edge)
[CC] encl.c (core)
[LD] encl.o encl_t.o -lsgx_trts encl.unsigned.so
Makefile:51: recipe for target 'encl.so' failed
make[1]: *** [encl.so] Error 127
Makefile:72: recipe for target 'build-Enclave' failed
make: *** [build-Enclave] Error 2

i followed the installation instructions inside the README, would appreciate some help.

Thanks,
Bar.

I have the same problem. May I ask which part of the environment setting is wrong?

Great!Solved,thanks!
