jrate-devel Mailing List for jRate

Hi,

I'm a student of University of York, and I'm trying to update some
features of jRate to cater RTSJ 1.1.
Now, I'm having the jRate source code, and the paper 'The Design and
Performance of the jRate Real-Time Java Implementation'. However, it's
hard to unstand this project in short time. Do you have more specific
materials to helping me unstand this project?

Thank you.

Hi Morgan,

Using the -m32 flag at JRate configure time gives me an error nanosleep()
not found. 

# ./configure --prefix....  CFLAGS=-m32
checking for pthread_create in -lpthread... no
checking for library containing nanosleep... no
configure: error: can't find nanosleep()

Without specifying -m32, it finds the it finds the pthread_create in
libpthread and doesn't care if nanosleep is present or not. I suppose I am
missing a 32 bit library but I can see libpthread.so in both /lib and
/lib64. Thanks for your help.

Cheers

Haseeb
