1 | The common case |
2 | ||
3 | ./autogen.sh && ./configure && make | |
4 | ||
5 | If something fails read the last lines. Typical reason to | |
6 | fail is a missing dependency, such as libtool or gettext. | |
7 | ||
8 | Autotools | |
9 | ||
10 | `./autogen.sh' generates all files needed to compile | |
11 | and install the code (run it after checkout from git) | |
12 | ||
13 | `make distclean' removes all unnecessary files, but the | |
14 | code can still be recompiled with "./configure; make" | |
15 | ||
16 | `make dist-gzip' (or -bzip2) creates a tarball that can | |
17 | be configured and compiled without running `./autogen.sh' | |
18 | ||
19 | Compiling | |
20 | ||
21 | Use SUID_CFLAGS and SUID_LDFLAGS when you want to define | |
22 | special compiler options for typical suid programs, for | |
23 | example: | |
24 | ||
25 | ./configure SUID_CFLAGS="-fpie" SUID_LDFLAGS="-pie" | |
26 | ||
27 | The SUID_* feature is currently supported for chfn, chsh, | |
b5b8805f | 28 | newgrp, su, write, mount, and umount. |

30 | Use DAEMON_CFLAGS and DAEMON_LDFLAGS when you want to define |
31 | special compiler options for daemons; supported for uuidd. | |
22a3b8c9 | 32 | |
03d00d49 KZ |
33 | Use SOLIB_CFLAGS and SOLIB_LDFLAGS when you want to define |
34 | special compiler options for shared libraries; supported for | |
35 | libmount, libblkid and libuuid. | |

37 | FIXME: add notes about klib and uClib. | |

39 | |
40 | Compile certain portion | |
41 | ||
42 | See ./configure --help and use --disable-* and --enable-* options. | |
43 | ||
44 | It's also possible to disable all the programs and enable only wanted. | |
45 | For example: | |
46 | ||
47 | ./configure --disable-all-programs --enable-fallocate | |
48 | ||
49 | Note that the configure script tracks dependencies between libs and | |
50 | tools. Always see warning messages and follow error messages if any | |
51 | dependence is necessary. For example to compile mount(8) you need also | |
52 | libmount, libblkid and libuuid: | |
53 | ||
54 | ./configure --disable-all-programs --enable-mount --enable-libmount \ | |
55 | --enable-libblkid --enable-libuuid | |
56 | ||
57 | ||

58 | Static linking |
59 | ||
60 | Use --enable-static-programs[=LIST] configure option when | |
61 | you want to use statically linked programs. | |
62 | ||
63 | Note, mount(8) uses get{pw,gr}nam() and getpwuid() | |
64 | functions for translation from username and groupname to | |
65 | UID and GID. These functions could be implemented by | |
66 | dynamically loaded independent modules (NSS) in your libc | |
67 | (e.g. glibc). These modules are not statically linked to | |
68 | mount(8) and mount.static is still using dlopen() like | |
69 | dynamically linked version. | |
70 | ||
71 | The translation won't work in environment where NSS | |
72 | modules are not installed. | |
73 | ||
74 | For example normal system (NSS modules are available): | |
75 | ||
76 | # ./mount.static -v -f -n -ouid=kzak /mnt/foo | |
77 | LABEL=/mnt/foo on /mnt/foo type vfat (rw,uid=500) | |
78 | ^^^^^^^ | |
79 | and without NSS modules: | |
80 | ||
81 | # chroot . ./mount.static -v -f -n -ouid=kzak /mnt/win | |
82 | LABEL=/mnt/win on /mnt/win type vfat (rw,uid=kzak) | |
83 | ^^^^^^^^ |
