Name: libaio Version: 0.3.106 Release: 1 Summary: Linux-native asynchronous I/O access library Copyright: LGPL Group: System Environment/Libraries Source: %{name}-%{version}.tar.gz BuildRoot: %{_tmppath}/%{name}-root # Fix ExclusiveArch as we implement this functionality on more architectures ExclusiveArch: i386 x86_64 ia64 s390 s390x ppc ppc64 ppc64pseries ppc64iseries alpha alphaev6 %description The Linux-native asynchronous I/O facility ("async I/O", or "aio") has a richer API and capability set than the simple POSIX async I/O facility. This library, libaio, provides the Linux-native API for async I/O. The POSIX async I/O facility requires this library in order to provide kernel-accelerated async I/O capabilities, as do applications which require the Linux-native async I/O API. %package devel Summary: Development files for Linux-native asynchronous I/O access Group: Development/System Requires: libaio Provides: libaio.so.1 %description devel This package provides header files to include and libraries to link with for the Linux-native asynchronous I/O facility ("async I/O", or "aio"). %prep %setup %build make %install [ "$RPM_BUILD_ROOT" != "/" ] && rm -rf $RPM_BUILD_ROOT make install prefix=$RPM_BUILD_ROOT/usr \ libdir=$RPM_BUILD_ROOT/%{_libdir} \ root=$RPM_BUILD_ROOT %clean [ "$RPM_BUILD_ROOT" != "/" ] && rm -rf $RPM_BUILD_ROOT %post -p /sbin/ldconfig %postun -p /sbin/ldconfig %files %defattr(-,root,root) %attr(0755,root,root) %{_libdir}/libaio.so.* %doc COPYING TODO %files devel %defattr(-,root,root) %attr(0644,root,root) %{_includedir}/* %attr(0755,root,root) %{_libdir}/libaio.so %attr(0644,root,root) %{_libdir}/libaio.a %changelog * Tue Jan 3 2006 Jeff Moyer - 0.3.106-1 - Add a .proc directive for the ia64_aio_raw_syscall macro. This sounds a lot like the previous entry, but that one fixed the __ia64_raw_syscall macro, located in syscall-ia64.h. This macro is in raw_syscall.c, which pretty much only exists for ia64. This bug prevented the package from building with newer version of gcc. * Mon Aug 1 2005 Jeff Moyer - 0.3.105-1 - Add a .proc directive for the ia64 raw syscall macro. * Fri Apr 1 2005 Jeff Moyer - 0.3.104-1 - Add Alpha architecture support. (Sergey Tikhonov ) * Tue Jan 25 2005 Jeff Moyer - 0.3.103-1 - Fix SONAME breakage. In changing file names around, I also changed the SONAME, which is a no no. * Thu Oct 14 2004 Jeff Moyer - 0.3.102-1 - S390 asm had a bug; I forgot to update the clobber list. Lucky for me, newer compilers complain about such things. - Also update the s390 asm to look more like the new kernel variants. * Wed Oct 13 2004 Jeff Moyer - 0.3.101-1 - Revert syscall return values to be -ERRNO. This was an inadvertant bug introduced when clobber lists changed. - add ppc64pseries and ppc64iseries to exclusivearch * Tue Sep 14 2004 Jeff Moyer - 0.3.100-1 - Switch around the tests for _PPC_ and _powerpc64_ so that the ppc64 platforms get the right padding. * Wed Jul 14 2004 Jeff Moyer - 0.3.99-4 - Ok, there was a race in moving the cvs module. Someone rebuild from the old cvs into fc3. *sigh* bumping rev. * Wed Jul 14 2004 Jeff Moyer - 0.3.99-3 - Actually provide libaio.so.1. * Tue Mar 30 2004 Jeff Moyer - 0.3.99-2 - Apparently the 0.3.93 patch was not meant for 0.3.96. Backed it out. * Tue Mar 30 2004 Jeff Moyer - 0.3.99-1 - Fix compat calls. - make library .so.1.0.0 and make symlinks properly. - Fix header file for inclusion in c++ code. * Thu Feb 26 2004 Jeff Moyer 0.3.98-2 - bah. fix version nr in changelog. * Thu Feb 26 2004 Jeff Moyer 0.3.98-1 - fix compiler warnings. * Thu Feb 26 2004 Jeff Moyer 0.3.97-2 - make srpm was using rpm to do a build. changed that to use rpmbuild if it exists, and fallback to rpm if it doesn't. * Tue Feb 24 2004 Jeff Moyer 0.3.97-1 - Use libc syscall(2) instead of rolling our own calling mechanism. This change is inspired due to a failure to build with newer gcc, since clobber lists were wrong. - Add -fpic to the CFLAGS for all architectures. Should address bz #109457. - change a #include from to . Fixes a build issue on s390. * Wed Jul 7 2003 Bill Nottingham 0.3.96-3 - fix paths on lib64 arches * Wed Jun 18 2003 Michael K. Johnson 0.3.96-2 - optimization in io_getevents from Arjan van de Ven in 0.3.96-1 - deal with ia64 in 0.3.96-2 * Wed May 28 2003 Michael K. Johnson 0.3.95-1 - ppc bugfix from Julie DeWandel * Tue May 20 2003 Michael K. Johnson 0.3.94-1 - symbol versioning fix from Ulrich Drepper * Mon Jan 27 2003 Benjamin LaHaise - bump to 0.3.93-3 for rebuild. * Mon Dec 16 2002 Benjamin LaHaise - libaio 0.3.93 test release - add powerpc support from Gianni Tedesco - add s/390 support from Arnd Bergmann * Fri Sep 12 2002 Benjamin LaHaise - libaio 0.3.92 test release - build on x86-64 * Thu Sep 12 2002 Benjamin LaHaise - libaio 0.3.91 test release - build on ia64 - remove libredhat-kernel from the .spec file * Thu Sep 5 2002 Benjamin LaHaise - libaio 0.3.90 test release * Mon Apr 29 2002 Benjamin LaHaise - add requires initscripts >= 6.47-1 to get boot time libredhat-kernel linkage correct. - typo fix * Thu Apr 25 2002 Benjamin LaHaise - make /usr/lib/libredhat-kernel.so point to /lib/libredhat-kernel.so.1.0.0 * Mon Apr 15 2002 Tim Powers - make the post scriptlet not use /bin/sh * Sat Apr 12 2002 Benjamin LaHaise - add /lib/libredhat-kernel* to %files. * Fri Apr 12 2002 Benjamin LaHaise - make the dummy install as /lib/libredhat-kernel.so.1.0.0 so that ldconfig will link against it if no other is installed. * Tue Jan 22 2002 Benjamin LaHaise - add io_getevents * Tue Jan 22 2002 Michael K. Johnson - Make linker happy with /usr/lib symlink for libredhat-kernel.so * Mon Jan 21 2002 Michael K. Johnson - Added stub library * Sun Jan 20 2002 Michael K.
