-shared

Produce a shared object which can then be linked with other objects to form an executable. Not all systems support this option. For predictable results, you must also specify the same set of options that were used to generate code (-fpic, -fPIC, or model suboptions) when you specify this option.[1]

-fpic

Generate position-independent code ( PIC ) suitable for use in a shared library, if supported for the target machine. Such code accesses all constant addresses through a global offset table ( GOT ). The dynamic loader resolves the GOT entries when the program starts (the dynamic loader is not part of GCC ; it is part of the operating system). If the GOT size for the linked executable exceeds a machine-specific maximum size, you get an error message from the linker indicating that -fpic does not work; in that case, recompile with -fPIC instead. (These maximums are 8k on the SPARC and 32k on the m68k and RS/6000 . The 386 has no such limit.)

Position-independent code requires special support, and therefore works only on certain machines. For the 386, GCC supports PIC for System V but not for the Sun 386i. Code generated for the IBM RS/6000 is always position-independent.

When this flag is set, the macros "__pic__" and "__PIC__" are defined to 1.

-fPIC

If supported for the target machine, emit position-independent code, suitable for dynamic linking and avoiding any limit on the size of the global offset table. This option makes a difference on the m68k, PowerPC and SPARC .

Position-independent code requires special support, and therefore works only on certain machines.

When this flag is set, the macros "__pic__" and "__PIC__" are defined to 2.

-fpie

-fPIE

These options are similar to -fpic and -fPIC, but generated position independent code can be only linked into executables. Usually these options are used when -pie GCC option will be used during linking.

-fpie and -fPIE both define the macros "__pie__" and "__PIE__". The macros have the value 1 for -fpie and 2 for -fPIE. 

Pseudo-assembly:

PIC: This would work whether the code was at address 100 or 1000

100: COMPARE REG1, REG2

101: JUMP_IF_EQUAL CURRENT+10

...

111: NOP

Non-PIC: This will only work if the code is at address 100

100: COMPARE REG1, REG2

101: JUMP_IF_EQUAL 111

...

111: NOP

If your code is compiled with -fPIC, it's suitable for inclusion in a library - the library must be able to be relocated from its preferred location in memory to another address, there could be another already loaded library at the address your library prefers.

### This file configures various client-side behaviors.

###

### The commented-out examples below are intended to demonstrate

### how to use this file.

### Section for authentication and authorization customizations.

[auth]

### Set password stores used by Subversion. They should be

### delimited by spaces or commas. The order of values determines

### the order in which password stores are used.

### Valid password stores:

###   gnome-keyring        (Unix-like systems)

###   kwallet              (Unix-like systems)

###   keychain             (Mac OS X)

###   windows-cryptoapi    (Windows)

# password-stores = gnome-keyring,kwallet

###

### Set KWallet wallet used by Subversion. If empty or unset,

### then the default network wallet will be used.

# kwallet-wallet =

###

### Include PID (Process ID) in Subversion application name when

### using KWallet. It defaults to 'no'.

# kwallet-svn-application-name-with-pid = yes

###

### The rest of this section in this file has been deprecated.

### Both 'store-passwords' and 'store-auth-creds' can now be

### specified in the 'servers' file in your config directory.

### Anything specified in this section is overridden by settings

### specified in the 'servers' file.

###

### Set store-passwords to 'no' to avoid storing passwords in the

### auth/ area of your config directory.  It defaults to 'yes',

### but Subversion will never save your password to disk in

### plaintext unless you tell it to (see the 'servers' file).

### Note that this option only prevents saving of *new* passwords;

### it doesn't invalidate existing passwords.  (To do that, remove

### the cache files by hand as described in the Subversion book.)

# store-passwords = no

### Set store-auth-creds to 'no' to avoid storing any subversion

### credentials in the auth/ area of your config directory.

### It defaults to 'yes'.  Note that this option only prevents

### saving of *new* credentials;  it doesn't invalidate existing

### caches.  (To do that, remove the cache files by hand.)

# store-auth-creds = no

### Section for configuring external helper applications.

[helpers]

### Set editor-cmd to the command used to invoke your text editor.

###   This will override the environment variables that Subversion

###   examines by default to find this information ($EDITOR,

###   et al).

# editor-cmd = editor (vi, emacs, notepad, etc.)

### Set diff-cmd to the absolute path of your 'diff' program.

###   This will override the compile-time default, which is to use

###   Subversion's internal diff implementation.

# diff-cmd = diff_program (diff, gdiff, etc.)

### Set diff3-cmd to the absolute path of your 'diff3' program.

###   This will override the compile-time default, which is to use

###   Subversion's internal diff3 implementation.

# diff3-cmd = diff3_program (diff3, gdiff3, etc.)

### Set diff3-has-program-arg to 'yes' if your 'diff3' program

###   accepts the '--diff-program' option.

# diff3-has-program-arg = [yes | no]

### Set merge-tool-cmd to the command used to invoke your external

### merging tool of choice. Subversion will pass 4 arguments to

### the specified command: base theirs mine merged

# merge-tool-cmd = merge_command

### Section for configuring tunnel agents.

[tunnels]

### Configure svn protocol tunnel schemes here.  By default, only

### the 'ssh' scheme is defined.  You can define other schemes to

### be used with 'svn+scheme://hostname/path' URLs.  A scheme

### definition is simply a command, optionally prefixed by an

### environment variable name which can override the command if it

### is defined.  The command (or environment variable) may contain

### arguments, using standard shell quoting for arguments with

### spaces.  The command will be invoked as:

###   <command> <hostname> svnserve -t

### (If the URL includes a username, then the hostname will be

### passed to the tunnel agent as <user>@<hostname>.)  If the

### built-in ssh scheme were not predefined, it could be defined

### as:

# ssh = $SVN_SSH ssh -q -o ControlMaster=no

### If you wanted to define a new 'rsh' scheme, to be used with

### 'svn+rsh:' URLs, you could do so as follows:

# rsh = rsh

### Or, if you wanted to specify a full path and arguments:

# rsh = /path/to/rsh -l myusername

### On Windows, if you are specifying a full path to a command,

### use a forward slash (/) or a paired backslash (\\) as the

### path separator.  A single backslash will be treated as an

### escape for the following character.

### Section for configuring miscelleneous Subversion options.

[miscellany]

### Set global-ignores to a set of whitespace-delimited globs

### which Subversion will ignore in its 'status' output, and

### while importing or adding files and directories.

### '*' matches leading dots, e.g. '*.rej' matches '.foo.rej'.

# global-ignores = *.o *.lo *.la *.al .libs *.so *.so.[0-9]* *.a *.pyc *.pyo

#   *.rej *~ #*# .#* .*.swp .DS_Store

### Set log-encoding to the default encoding for log messages

# log-encoding = latin1

### Set use-commit-times to make checkout/update/switch/revert

### put last-committed timestamps on every file touched.

# use-commit-times = yes

### Set no-unlock to prevent 'svn commit' from automatically

### releasing locks on files.

# no-unlock = yes

### Set mime-types-file to a MIME type registry file, used to

### provide hints to Subversion's MIME type auto-detection

### algorithm.

# mime-types-file = /path/to/mime.types

### Set preserved-conflict-file-exts to a whitespace-delimited

### list of patterns matching file extensions which should be

### preserved in generated conflict file names.  By default,

### conflict files use custom extensions.

# preserved-conflict-file-exts = doc ppt xls od?

### Set enable-auto-props to 'yes' to enable automatic properties

### for 'svn add' and 'svn import', it defaults to 'no'.

### Automatic properties are defined in the section 'auto-props'.

# enable-auto-props = yes

### Set interactive-conflicts to 'no' to disable interactive

### conflict resolution prompting.  It defaults to 'yes'.

# interactive-conflicts = no

### Section for configuring automatic properties.

[auto-props]

### The format of the entries is:

###   file-name-pattern = propname[=value][;propname[=value]...]

### The file-name-pattern can contain wildcards (such as '*' and

### '?').  All entries which match (case-insensitively) will be

### applied to the file.  Note that auto-props functionality

### must be enabled, which is typically done by setting the

### 'enable-auto-props' option.
