Failed to build DeepMatch with Programmer Studio 6.1.0.1-preview

[GavynDracula]

Hi,

Recently, we want to run DeepMatch on our Netronome Agilio SmartNIC, but we failed.

When we build the project of deepmatch according to READEME, the Programmer Studio reports us several errors like "struct 'pktio_meta' has no field 'xxx'", e.g., "plugin.c(302): error : struct 'pktio_meta' has no field 'pkt_buf'".

We are really new to the development of Netronome SmartNICs and not able to figure out the root cause of this compilation error. Do you know the reason of that?

Hi, The README states "we used version 6.0.3.1 build 3241" of the SDK. Please grep your Netronome SDK source to find that structure and see how it is defined -- does it include the pkt_buf field (it may be in a file called pktio.h)?

[GavynDracula]

Hi, Joel. Thanks for your reply. Acutally, I have checked the declaration of 'struct pktio_meta' in the pktio.h, and there are reallly no such fields. In my SDK (version 6.1.0.1), 'struct pktio_meta" is defined as follow.

struct pktio_meta {
    union {
        struct {
            struct nbi_meta_pkt_info p_nbi;     /**< Std NBI-formatted metadata

It seems that Netronome has changed their some APIs in the latest SDK?

[jhypolite]

Yes, the API changed. Someone else tried installing with 6.1.0.1-preview and ran into the same compiler error. They reverted to 6.0.3.1 and the install worked. Are you able to contact Netronome to obtain the compatible SDK version? https://help.netronome.com/support/home

[GavynDracula]

Yes, I have submitted a ticket to apply for an older stable version. However, Netronome has not replied to me...

[GavynDracula]

Hi, Joel. We can only install the 6.0.4.1 version of SDK. However, when we compile DeepMatch with 6.0.4.1, a new error "error : No LM for spilling. (-Qspill=3). compilation stopped" appeared ... Do you learn about this compilation error?

[jhypolite]

Has Netronome responded about the SDK? The new error could be due to your build settings? You need reduced threads mode and to turn off/reduce features that are not needed, like debugging and multicast groups.

[jhypolite]

Note that Netronome has made SDK 6.0.3 available upon request. You must send them an explicit request for it.
