Library tripled in size with GCC 4.2

[Eric Gorr]

I am using Mac OS X 10.5 and Xcode 3.1.1.

With GCC 4.0, the size of the debug version of my static library was  
~400mb. With GCC 4.2, the amount of debug information increased  
dramatically and it is now ~1.2GB.

However, the real problem appears to be with the version of libtool  
that I am using. Here are the details:



$/Developer/usr/bin/libtool -V
Apple Computer, Inc. version cctools-698.1

$ lipo -info /Developer/usr/bin/libtool
Architectures in the fat file: /Developer/usr/bin/libtool are: i386  
ppc7400



So, it is no surprise that a 32-bit version of libtool would be  
failing with this error message:



/Developer/usr/bin/libtool: can't vm_allocate() buffer for output  
file: libCore.a of size 1206037468 ((os/kern) no space available)



So, my question is does a 64-bit version of libtool exist?
If so, how easy or practical would it be to get Xcode to use it  
instead of the 32-bit version?
Anyone played around with doing this?


Any comments, hints or suggestions would be appreciated.

thank you.



p.s. here are the details on GCC & ld:
