#23303: procfs fails to compile under Snow Leopard ------------------------------------------+--------------------------------- Reporter: hans.ekkehard.plesser@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 1.8.2 Keywords: | Port: procfs ------------------------------------------+--------------------------------- Comment(by hans.ekkehard.plesser@…): This error persists under OSX 10.6.4 with XCode 3.2.3, MacPorts version 1.9.1 and procfs version 2.0. I have identified the following issues: * The Makefile for procfs has `g++` hardcoded. Thus, procfs is compiled with the currently active compiler, not with the MacPorts default compiler as it should. * procfs code compiles only if I select g++ 4.0.1. With 4.2.1 (which should be used according to Macports rules) or 4.4 (which I commonly use), several issues occur: - g++ 4.4 barfs at `-arch` options and does not compile anything; - g++ 4.2 does not accept `goto` instructions crossing variable initializations (in functions `OPEN_HANDLER(proc__windows__identify)` and `READ_HANDLER(system__firmware__variables)` - the system calls `IOConnectMethodStructureIStructureO()` and `IOConnectMethodScalarIScalarO()` are not known when using g++ 4.2, even with the 10.5 SDK; they were deprecated for 10.5 and have been removed from 10.6, see [http://developer.apple.com/mac/library/documentation/Darwin/Conceptual/64bit... Apple Developer Documentation]; they are replaced by `IOConnectCallStructMethod()` and `IOConnectCallScalarMethod()`, but I feel out of my depth here and have not tried to adapt the code. * Using g++ 4.0.1, compilation goes through, but the resulting code cannot be linked against pcre, which has been built (properly) using 4.2.1. I hope someone who knows more about MacPorts and OSX internals can fix the Makefiles/Portfile to respect MacPorts conventions about using the default system compiler (ie 4.2.1 for 10.6) and fix those system calls. -- Ticket URL: <http://trac.macports.org/ticket/23303#comment:4> MacPorts <http://www.macports.org/> Ports system for Mac OS
