Re: [Libtirpc-devel] [EXTERNAL] - Re: Proposed enhancement to libtiroc

I’m sorry I didn’t see this proposal earlier. My bad.

What’s the justification for putting xdr_fixedstring() in libtirpc rather than in your application?

Thanks,
Dave

Steve,

It's been a long time since my proposal - but I'm still interested in this improvement. We are being forced to update our system, including alignment with tirpc.
I've pulled the code from git://git.linux-nfs.org/projects/steved/libtirpc.git<https://urldefense.com/v3/__http:/git.linux-nfs.org/projects/steved/libtirpc.git__;!!Obbck6kTJA!fNstzzAIWziPmmZTVITCae__iNLT77ZVJT0x8-KMXixElWPiDEw1wv05jUj0W4xfjuX6wqtZHQoxdK_FHzoU$>
But I'm not exactly sure how to build.

Following from autgen.sh - I've installed automake, libtool, and I opted out from gssapi (--disable-gssapi) - got the library to work.
Anything else I'm missing ?

For the commit - do you want me to commit a feature branch - add PR, or just a patch file. Not sure if anything changed since 2022.

Regards,
Yair

Thank you for that clarification!

Yair, please feel free to post the needed patches.
