src/Makefile: keep private headers in <liburing/*.h> 2019-07-24T15:11:44+00:00 Stefan Hajnoczi stefanha@redhat.com 2019-07-24T08:24:50+00:00 c31c7ec4bcd7bb0d7b28897d730431c02b9d4ea1 It is not possible to install barrier.h and compat.h into the top-level /usr/include directly since they are likely to conflict with other software. io_uring.h could be confused with the system's kernel header file. Put liburing headers into <liburing/*.h> so there is no chance of conflicts or confusion. Existing applications continue to build successfully since the location of <liburing.h> is unchanged.

It is not possible to install barrier.h and compat.h into the top-level
/usr/include directly since they are likely to conflict with other
software.  io_uring.h could be confused with the system's kernel header
file.

Put liburing headers into <liburing/*.h> so there is no chance of
conflicts or confusion.

Existing applications continue to build successfully since the location
of <liburing.h> is unchanged.  In-tree examples and tests require
modification because src/liburing.h is moved to src/include/liburing.h.

Makefiles: Support specifying CFLAGS on the command line 2019-07-08T21:25:57+00:00 Bart Van Assche bvanassche@acm.org 2019-07-08T19:57:47+00:00 64f89fa1469122ec480bf7d315a61de44c0a78c4 This patch makes the liburing build work as expected for e.g. the following command: make CFLAGS=-m32 and avoids that the build fails as follows for the above command: make[1]: Entering directory 'liburing/test' cc -m32 -o poll poll.c -luring /usr/bin/ld: cannot find -luring collect2: error: ld returned 1 exit status Makefile:18: recipe for target 'poll' failed make[1]: *** [poll] Error 1 make[1]: Leaving directory 'software/liburing/test' Makefile:12: recipe for target 'all' failed make: *** [all] Error 2 Signed-off-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Jens Axboe <axboe@kernel.dk> 
This patch makes the liburing build work as expected for e.g. the following
command:

make CFLAGS=-m32

and avoids that the build fails as follows for the above command:

make[1]: Entering directory 'liburing/test'
cc -m32 -o poll poll.c -luring
/usr/bin/ld: cannot find -luring
collect2: error: ld returned 1 exit status
Makefile:18: recipe for target 'poll' failed
make[1]: *** [poll] Error 1
make[1]: Leaving directory 'software/liburing/test'

example/io_uring-test.c: Fix iovecs increment 2019-06-13T09:04:32+00:00 Stephen Bates sbates@raithlin.com 2019-06-13T09:04:32+00:00 733223acd6540cc38d7e0b1235f74b42d643b138 This example misses an increment though the iovecs array. This causes the same buffer to be filled from the block device every time. It would be good to fix this since it is one of the first examples a new-comer to io_uring is exposed too.
