Error building how to deploy demo

Troubleshooting
#1

The recent API change breaks the example in tvm/apps/howto_deploy If you try to make the project with the current setup you get several warnings such as:

warning:

’DCHECK_NE’ macro redefined [-Wmacro-redefined]

#define DCHECK_NE(x, y) CHECK((x) != (y))

Other involved macros are DCHECK_EQ, DCHECK_GE, DCHECK_LE, etc. The error is to symbols not found, so its probably due to name changes:

Undefined symbols for architecture x86_64:

Will spend some time looking for the missing/changed names, but if anyone has seen this and has a solution, please let me know.

Thanks!

Hi @alopez_13, thanks for reporting!

The GetEntry method is defined in src/runtime/logging.cc. Would you like to check if this method exist? Thanks a lot!

#3

Oh I see. Would you like to add an include item in tvm_runtime_pack.cc?

#include "../../src/runtime/logging.cc"

Adding the include got rid of the error. Thanks!

The warnings are due to re-definitions of the macros. Not a show stopper.

#5

would you like to send a PR for the fix? Thanks a lot!

#6

Sure, it’s a minor fix. I haven’t fixed the duplicate macro definitions, but the build is successful and it gives the expected result. I’ll track the duplicate macros later.
