|
|
.
|
|
.
|
|
.SH NAME
|
|
.
|
|
freetype-config \- Get information about a libfreetype installation
|
|
.
|
|
.
|
|
.SH SYNOPSIS
|
|
.
|
|
.B freetype-config
|
|
.RI [ options ]
|
|
.
|
|
.
|
|
.SH DESCRIPTION
|
|
.
|
|
.B freetype-config
|
|
returns information needed for compiling and linking programs with the
|
|
FreeType library, such as linker flags and compilation parameters.
|
|
.
|
|
Alternatively, it can be used to query information about the
|
|
FreeType library version installed on the system, such as the
|
|
installation (directory path) prefix or the FreeType version number.
|
|
.
|
|
.PP
|
|
If
|
|
.BR pkg-config (1)
|
|
is found in the path,
|
|
.B freetype-config
|
|
acts as a wrapper for
|
|
.BR pkg-config .
|
|
.
|
|
.PP
|
|
This program is part of the FreeType package.
|
|
.
|
|
.
|
|
.SH OPTIONS
|
|
.
|
|
There are two types of options: output/display selection options, and
|
|
path override options.
|
|
.
|
|
.
|
|
.SS Output selection options
|
|
.
|
|
Only one of the output selection options should be given at each program
|
|
invocation.
|
|
.
|
|
.TP
|
|
.B \-\-prefix
|
|
Return the prefix value of the installed FreeType library (the default
|
|
prefix will be `/usr' in most cases for distribution-installed
|
|
packages).
|
|
.
|
|
.TP
|
|
.B \-\-exec-prefix
|
|
Return the executable prefix value of the installed FreeType library
|
|
(will often be the same as the prefix value).
|
|
.
|
|
.TP
|
|
.B \-\-ftversion
|
|
Return the FreeType version number, directly derived from file
|
|
`freetype.h'.
|
|
.
|
|
.TP
|
|
.B \-\-version
|
|
Return the `libtool version' of the FreeType library.
|
|
.
|
|
.TP
|
|
.B \-\-libtool
|
|
Return the library name for linking with libtool.
|
|
.
|
|
.TP
|
|
.B \-\-libs
|
|
Return compiler flags for linking with the installed FreeType library.
|
|
.
|
|
.TP
|
|
.B \-\-cflags
|
|
Return compiler flags for compiling against the installed FreeType library.
|
|
.
|
|
.TP
|
|
.B \-\-static
|
|
Make command line options display flags for static linking.
|
|
.
|
|
.TP
|
|
.B \-\-help
|
|
Show help and exit.
|
|
.
|
|
.
|
|
.SS Path override options
|
|
.
|
|
These affect any selected output option, except the libtool version
|
|
returned by
|
|
.BR \-\-version .
|
|
.
|
|
.TP
|
|
.BI \-\-prefix= PREFIX
|
|
Override
|
|
.B \-\-prefix
|
|
value with
|
|
.IR PREFIX .
|
|
.
|
|
This also sets
|
|
.BI \-\-exec-prefix= PREFIX
|
|
if option
|
|
.B \-\-exec-prefix
|
|
is not explicitly given.
|
|
.
|
|
.TP
|
|
.BI \-\-exec-prefix= EPREFIX
|
|
Override
|
|
.B \-\-exec-prefix
|
|
value with
|
|
.IR EPREFIX .
|
|
.
|
|
.
|
|
.SH BUGS
|
|
In case the libraries FreeType links to are located in non-standard
|
|
directories, and
|
|
.BR pkg-config (1)
|
|
is not available, the output from option
|
|
.B \-\-libs
|
|
might be incomplete.
|
|
.
|
|
It is thus recommended to use the
|
|
.BR pkg-config (1)
|
|
interface instead, which is able to correctly resolve all dependencies.
|
|
.
|
|
.PP
|
|
Setting
|
|
.B \-\-exec-prefix
|
|
(either explicitly or implicitly) might return incorrect results if
|
|
combined with option
|
|
.BR \-\-static .
|
|
.
|
|
The same problem can occur if you set the
|
|
.B SYSROOT
|
|
environment variable.
