It is +a complete autotools based build system which demonstrates the +required changes in configure.ac, Makefile.am etc to successfuly +detect for and build an application against libgfapi. + +There are two approaches to building a libgfapi based application: + +1. In the presence of pkg-config in your build system. +This is the recommended approach which is also used in this example. +For this approach to work, you need to build glusterfs by passing +--pkgconfigdir=/usr/lib64/pkgconfig (or the appropriate directory) +in your distro. This already happens if you build RPMs with the +glusterfs.spec provided in glusterfs.git. You will also need to +install glusterfs-api RPM. + +2. In the absence of pkg-config in your build system. +Make sure your LDFLAGS includes -L/path/to/lib where libgfapi.so is +installed and -I/path/to/include/glusterfs where the 'api' directory +containing the headers are available. diff --git a/api/examples/autogen.sh b/api/examples/autogen.sh new file mode 100755 index 000000000..1fee6be11 --- /dev/null +++ b/api/examples/autogen.sh @@ -0,0 +1,5 @@ +#!/bin/sh + +aclocal +autoconf +automake --foreign diff --git a/api/examples/configure.ac b/api/examples/configure.ac new file mode 100644 index 000000000..b80177a4e --- /dev/null +++ b/api/examples/configure.ac @@ -0,0 +1,12 @@ + +AC_INIT([glfs-test],[0.1],[gluster-devel@nongu.org]) + +AM_INIT_AUTOMAKE + +AC_CONFIG_FILES([Makefile]) + +AC_PROG_CC + +PKG_CHECK_MODULES([GLFS], [glusterfs-api >= 3]) + +AC_OUTPUT diff --git a/api/examples/glfsxmp.c b/api/examples/glfsxmp.c new file mode 100644 index 000000000..1883b54bc --- /dev/null +++ b/api/examples/glfsxmp.c @@ -0,0 +1,57 @@ +#include <stdio.h> +#include <errno.h> +#include "api/glfs.h" +#include <string.h> +#include <time.h> + +int +main (int argc, char *argv[]) +{ + glfs_t *fs = NULL; + int ret = 0; + glfs_fd_t *fd = NULL; + struct stat sb = {0, }; + char readbuf[32]; + char writebuf[32]; + + char *volname = "iops"; + char *filename = "/filename2"; + + fs = glfs_new (volname); + if (!fs) { + fprintf (stderr, "glfs_new: returned NULL\n"); + return 1; + } + +// ret = glfs_set_volfile (fs, "/tmp/filename.vol"); + + ret = glfs_set_volfile_server (fs, "socket", "localhost", 24007); + +// ret = glfs_set_volfile_server (fs, "unix", "/tmp/gluster.sock", 0); + + ret = glfs_set_logging (fs, "/dev/stderr", 7); + + ret = glfs_init (fs); + + fprintf (stderr, "glfs_init: returned %d\n", ret); + + + ret = glfs_lstat (fs, filename, &sb); + fprintf (stderr, "%s: (%d) %s\n", filename, ret, strerror (errno)); + + fd = glfs_creat (fs, filename, O_RDWR, 0644); + fprintf (stderr, "%s: (%p) %s\n", filename, fd, strerror (errno)); + + sprintf (writebuf, "hi there\n"); + ret = glfs_write (fd, writebuf, 32, 0); + + glfs_lseek (fd, 0, SEEK_SET); + + ret = glfs_read (fd, readbuf, 32, 0); + + printf ("read %d, %s", ret, readbuf); + + glfs_close (fd); + + return ret; +} |
