Hello,
I am currently porting an IRIX/Performer 2.1 based application to
Linux/Performer 2.4.
First of all, is there a document (or web page) describing issues in porting
performer applications from IRIX to Linux. I tried searching through the list
archives as well the Performer FAQ but did not come across much.
I have the following two issues which I would appreciate any assistance I can
get:
1) There is a function for 'sproc' within the Performer library. Does this
function do anything? Does it actually perform a similar function as the
IRIX 'sproc'? I generally used sproc with the PR_SADDR flag set. If the
performer version does not offer the same service, would Linux's 'clone'
function with the CLONE_VM flag set be the closest match?
2) It would appear that if an exception is thrown from a performer derived
object, the performer library intercepts this exception and causes a
signal to be raised which terminates the application. If this is true,
is there any way to build the application so that the standard exception
handling is re-enabled?
System Specs:
SGI 550
Dual PIII Xeon 800MHz
512MB RAM
VR3 Graphics card
RedHat 6.2
SGI ProPack 1.3 VWE
Performer 2.4
Thank you,
John Walter
