(could someone give some infos instead of laughing ?), user space profiling in libgmon. I wish someone of the Linux libc developers would write this chapter. All i can say now that there is going to be a change from the a.out executable format to the elf (executable and linkable format) which also means a change in building shared libraries. Currently both formats (a.out and elf) are supported. <P> <P> Most parts of the Linux libc package are under the Library GNU Public License, though some are under a special exception copyright like crt0.o. For commercial binary distributions this means a restriction that forbids statically linked executables. Dynamically linked executables are again a special exception and Richard Stallman of the FSF said: <P> <P><I>[...] But it seems to me that we should unambiguously permit distribution of a dynamically linked executable *without* accompanying libraries, provided that the object files that make up the executable are themselves unrestricted according to section 5 [...] So I'll make the decision now to permit this. Actually updating the LGPL will have to wait for when I have time to make and check a new version.</I> <P> <BR> <HR> <P><ADDRESS> <I>Converted on: <BR> Fri Mar 29 14:43:04 EST 1996</I> </ADDRESS> </BODY> </HTML>
