AaronW writes "While checking the GCC website I saw that GCC version 3.4 was officially released on April 18th. Version 3.4 includes numerous changes and enhancements, including better optimization, and the ability to build a profiled version of gcc which is 7.5-11% faster on i386 hardware.

Profiling shared libraries

[wowbagger]

Has the ability to profile shared libraries been fixed? I have tried to do this, and even if you compile a shared library with -pg, and specify it in the LD_PROFILE environment variable, the resulting profile file cannot be processed by gprof V2.4 - instead you get "error: unsupported profile revision 131,071"

I *really* need to profile a shared library, and building it as a staticly linked executable is not an option.

GCJ

[InsaneCreator]

Could someone explain how well does the gcj Java compiler work? I hear that AWT and Swing are not really usable, so how well does it work with SWT or maybe even wxWidgets?

I'm currently in the process of choosing the language/tools for a cross platform app (open source, of course) and I've narrowed the selection down to Java+gcj and c++. Native executables & widgets are a must, since my target audince most likely won't have a JVM installed.

Re:Broken C++ ABI ... again

[Dr.Dubious DDQ]

Well, if you want to be technical about it, it's not "Broken" C++ ABI, but a "Finally fixed, even though that makes it no longer bug-for-bug compatible with older GCC C++ ABI's"...

As I understand it, they've been working towards a more standards compliant C++ implementation, and that's why the binary compatibility gets lost.

I am, though, hoping that there was NOT a loss of compatibility between the 3.3.3 that I'm using now and the 3.4 series. Will find out once I clean off enough disk space to finish compiling up slack packages for myself...
