how to build mbuffer for macox

[echeng]

Thank you so much for this. I'm using mbuffer and IP over Thunderbolt and am getting 1GB/s during send/recv between machines.

Hi echeng,

I too compiled mbuffer from Lundman's tarball and when I run it, I notice that the buffer is always 0% full. Even your screenshot shows this...

Is this right?

[lundman]

That was one of the things that OSX is missing, a way to pass values around with pthread. As a quick port we went without it. If you want that to work, you will need to find a more correct porting solution.

Trying to get buffer installed but I get an error regarding openssl.

I ran "./configure" and then "make":

Code: Select all

Any help appreciated as I am using send/receive a lot shipping TBs.

and I have a fresh install of openssl via "brew install openssl"

Sounds like you should add to configure with ./configure CPPFLAGS=-I/usr/local/ssl/include (change depending on where brew sticks SSL). That probably then also needs LDFLAGS=-L/usr/local/ssl/lib too

Worked. Thanks!

brew placed it in /usr/local/openssl....

happy camper. But I sure want the next miniMac that I hope will be announced this fall to have more memory than 16GB. zfs eats memory, a lot of memory

lundman's tarball compiles nicely for me.

Just in case anyone else can't compile it, you can get the original buffer from MacPorts, and I believe it has enough of the same functionality. (I haven't tried it though.)
