[SPDK] Re: nvmf_tgt does not start with -L flag though SPDK configured with --enable-debug option

Hi, Wenhua

I guess you were using a stale nvmf_tgt, not the newly built nvmf_tgt.
From v20.07, applications will be built at build/bin/*.
So just try:  build/bin/nvmf_tgt -m 0x3f -e 0x20 -L nvme -L nvmf -L nvmf_tcp

 --Thanks

Subject: [SPDK] nvmf_tgt does not start with -L flag though SPDK configured with --enable-debug option

Hi,

I just had my SPDK system updated to v20.07.

While testing my NVMe-oF initiator, I wanted to check target side log, so I configured the SPDK with the –enable-debug option and ran make.

  1.  make clean
  2.  ./configure –enable-debug
  3.  Make

I then tried to start NVMe-oF target with -L flag but nvmf_tgt could not start.

~/spdk/spdk$ sudo app/nvmf_tgt/nvmf_tgt -m 0x3f -e 0x20 -L nvme -L nvmf -L nvmf_tcp
2020-08-20 00:50:38.757781 [0x7f55b3d75980] app.c: 943:spdk_app_parse_args: *ERROR*: app/nvmf_tgt/nvmf_tgt must be configured with --enable-debug for -L flag app/nvmf_tgt/nvmf_tgt [options]
options:
-c, --config <config>     config file (default none)
     --json <config>       JSON config file (default none)
     --json-ignore-init-errors
                           don't exit on invalid config entry ….

This used to work with v20.01 (or v20.04).

What could be wrong here?

Thanks,
-Wenhua Liu
