Re: [Discuss-gnuradio] cmake build

[Michael Dickens]

Unless Josh changed something recently, the cmake build (with volk disabled) 
worked for me under 10.6.8, XCode 3.2.3, 64-bit.  It looks like Ben is doing 
this testing on 10.5.8, XCode 3.1.4 -- which by default will use 32-bit for 
either PPC or Intel compiling, and, really, getting 64-bit was somewhat of a 
challenge until 10.6.  A "fat" or "universal" build o 10.5 meant 32-bit PPC and 
Intel merged into a single file.  IIRC, gcc under 10.5.8 could be coerced into 
doing 64-bit, but doing so was much more reliable using Apple's interface.  All 
of that changed with 10.6, since 64-bit was the default for any capable 
processor (and, all processors were Intel, and mostly legacy ones were 32-bit 
only), and "universal" meant (and still means) both 32- and 64-bit Intel 
compiling (merged).  Given that "we" designed the GR autotools build to work on 
OSX with both 32- and 64-bit compiling, starting early in 10.5 days, I'm glad 
that that build still works correctly.

With the above I mind, it would probably help to know from Ben what "arch" and 
"uname -a" return. Looking at Josh's pastebin change, I would bet that 
CMAKE_SYSTEM_PROCESSOR is "i386" (it is for all Intel OSX builds, as far as I 
know).  But, under 10.5,  CMAKE_SYSTEM_PROCESSOR should probably be "i386", not 
"x86_64" -- but, it really depends on what Ben's system is / provides. - MLD
