<h4 class="subsubsection">1.4.8.1 Project Variables</h4>

<dl>
<dt><a name="index-LIBRARY_005fNAME"></a>Library project: <strong>LIBRARY_NAME</strong></dt>
<dd><p><code>LIBRARY_NAME</code> should be assigned the list of name of libraries to
be generated.  Most UNIX systems expect that the filename for the
library has the word <samp>lib</samp> prefixed to the name; i.e. the <samp>c</samp>
library has filename of <samp>libc</samp>.  Prefix the <samp>lib</samp> to the
library name when it is specified in the <code>LIBRARY_NAME</code> variable
because the Makefile Package will not automatically prefix it.
</p></dd></dl>

<dl>
<dt><a name="index-C_005fFILES"></a>Library project: <strong>C_FILES</strong></dt>
<dd><p><code>xxx_C_FILES</code> is the list of C files, with a <samp>.c</samp> extension,
that are to be compiled to generate the <strong>xxx</strong> library.
Replace the <strong>xxx</strong> with the name of the library as listed by
the <code>LIBRARY_NAME</code> variable.
</p></dd></dl>

<dl>
<dt><a name="index-OBJC_005fFILES"></a>Library project: <strong>OBJC_FILES</strong></dt>
<dd><p><code>xxx_OBJC_FILES</code> is the list of Objective-C files, with a <samp>.m</samp>
extension, that are to be compiled to generate the <strong>xxx</strong> library.
Replace the <strong>xxx</strong> with the name of the library as listed by the
<code>LIBRARY_NAME</code> variable.
</p></dd></dl>

<dl>
<dt><a name="index-PSWRAP_005fFILES"></a>Library project: <strong>PSWRAP_FILES</strong></dt>
<dd><p><code>xxx_PSWRAP_FILES</code> is the list of PostScript wrap files, with a
<samp>.psw</samp> extension, that are to be compiled to generate the
<strong>xxx</strong> library.  PostScript wrap files are processed by the
<samp>pswrap</samp> utility which generates a <samp>.c</samp> and a <samp>.h</samp> file
from each <samp>.psw</samp> file; the generate <samp>.c</samp> file is the file
actually compiled.  Replace the <strong>xxx</strong> with the name of the
library as listed by the <code>LIBRARY_NAME</code> variable.
</p></dd></dl>

<dl>
<dt><a name="index-HEADER_005fFILES"></a>Library project: <strong>HEADER_FILES</strong></dt>
<dd><p><code>xxx_HEADER_FILES</code> is the list of header filenames that are to be
installed with the library.  If a filename has a directory path prefixed
to it then that prefix will be maintained when the headers are
installed.  It is up to the user to make sure that the installation
directory exists; otherwise, an error will occur when the library is
installed, see <a href="#library_002emake-variables">xxx_HEADER_FILES_INSTALL_DIR</a>.  Replace the <strong>xxx</strong> with
the name of the library as listed by the <code>LIBRARY_NAME</code> variable.
</p></dd></dl>

<dl>
<dt><a name="index-HEADER_005fFILES_005fDIR"></a>Library project: <strong>HEADER_FILES_DIR</strong></dt>
<dd><p><code>xxx_HEADER_FILES_DIR</code> is the relative path from the current
directory, where the makefile is located, to where the header files
specified by <code>xxx_HEADER_FILES</code> are located.  If a filename
specified in <code>xxx_HEADER_FILES</code> has a directory path prefixed to it
then that path will not be removed when the Makefile Package accesses
the files, so do not specify a path with <code>xxx_HEADER_FILES_DIR</code>
that is already prefixed to the header filenames, see <a href="#library_002emake-variables">xxx_HEADER_FILES_INSTALL_DIR</a>.  <code>xxx_HEADER_FILES_DIR</code>
is optional; leaving it blank or undefined, and the Makefile Package
assumes that the relative path to the header files is the current
directory where the makefile resides.  Replace the <strong>xxx</strong> with the
name of the library as listed by the <code>LIBRARY_NAME</code> variable.
</p></dd></dl>

<dl>
<dt><a name="index-HEADER_005fFILES_005fINSTALL_005fDIR"></a>Library project: <strong>HEADER_FILES_INSTALL_DIR</strong></dt>
<dd><p><code>xxx_HEADER_FILES_INSTALL_DIR</code> specifies the relative subdirectory
path below <code>GNUSTEP_HEADERS</code> where the header files are to be
installed.  If this directory or any of its parent directories do not
exist, then the Makefile Package will create them.  The Makefile Package
prefixes <code>xxx_HEADER_FILES_INSTALL_DIR</code> to each of the filenames in
<code>xxx_HEADER_FILES</code> when they are installed, so if the filenames in
<code>xxx_HEADER_FILES</code> already have a directory path prefixed then the
user is responsible for creating that directory, the Makefile Package
will not create.  <code>xxx_HEADER_FILES_INSTALL_DIR</code> is optional;
leaving it blank or undefined, and the Makefile Package assumes that the
installation directory is just <code>GNUSTEP_HEADERS</code> with no
subdirectory.  Replace the <strong>xxx</strong> with the name of the library as
listed by the <code>LIBRARY_NAME</code> variable.
</p></dd></dl>

<dl>
<dt><a name="index-CPPFLAGS"></a>Library project: <strong>CPPFLAGS</strong></dt>
<dd><p><code>xxx_CPPFLAGS</code> are additional flags that will be passed to the
compiler preprocessor when compiling Objective-C and C files to generate
the <strong>xxx</strong> library.  Adding flags here does not override the
default <code>CPPFLAGS</code>, see <a href="Overridable-Flags.html#Overridable-Flags">CPPFLAGS</a>, they are
in addition to <code>CPPFLAGS</code>.  These flags are specific to the
<strong>xxx</strong> library, see <a href="GNUmakefile_002epreamble.html#GNUmakefile_002epreamble">ADDITIONAL_CPPFLAGS</a>,
to see how to specify global preprocessor flags.  Replace the
<strong>xxx</strong> with the name of the listed as listed by the
<code>LIBRARY_NAME</code> variable.
</p></dd></dl>

<dl>
<dt><a name="index-OBJCFLAGS"></a>Library project: <strong>OBJCFLAGS</strong></dt>
<dd><p><code>xxx_OBJCFLAGS</code> are additional flags that will be passed to the
compiler when compiling Objective-C files to generate the <strong>xxx</strong>
library.  Adding flags here does not override the default
<code>OBJCFLAGS</code>, see <a href="Overridable-Flags.html#Overridable-Flags">OBJCFLAGS</a>, they are in
addition to <code>OBJCFLAGS</code>.  These flags are specific to the
<strong>xxx</strong> library, see <a href="GNUmakefile_002epreamble.html#GNUmakefile_002epreamble">ADDITIONAL_OBJCFLAGS</a>,
to see how to specify global compiler flags.  Replace the <strong>xxx</strong>
with the name of the library as listed by the <code>LIBRARY_NAME</code>
variable.
</p></dd></dl>

<dl>
<dt><a name="index-CFLAGS"></a>Library project: <strong>CFLAGS</strong></dt>
<dd><p><code>xxx_CFLAGS</code> are additional flags that will be passed to the
compiler when compiling C files to generate the <strong>xxx</strong> library.
Adding flags here does not override the default <code>CFLAGS</code>, see
<a href="Overridable-Flags.html#Overridable-Flags">CFLAGS</a>, they are in addition to <code>CFLAGS</code>.
These flags are specific to the <strong>xxx</strong> library, see
<a href="GNUmakefile_002epreamble.html#GNUmakefile_002epreamble">ADDITIONAL_CFLAGS</a>, to see how to specify global
compiler flags.  Replace the <strong>xxx</strong> with the name of the library
as listed by the <code>LIBRARY_NAME</code> variable.
</p></dd></dl>

<dl>
<dt><a name="index-LDFLAGS"></a>Library project: <strong>LDFLAGS</strong></dt>
<dd><p><code>xxx_LDFLAGS</code> are additional flags that will be passed to the
linker when it creates the <strong>xxx</strong> library.  Adding flags here does
not override the default <code>LDFLAGS</code>, see <a href="Overridable-Flags.html#Overridable-Flags">LDFLAGS</a>, they are in addition to <code>LDFLAGS</code>.  These flags
are specific to the <strong>xxx</strong> library, see
<a href="GNUmakefile_002epreamble.html#GNUmakefile_002epreamble">ADDITIONAL_LDFLAGS</a>, to see how to specify
global linker flags.  Replace the <strong>xxx</strong> with the name of the
library as listed by the <code>LIBRARY_NAME</code> variable.
</p></dd></dl>

<dl>
<dt><a name="index-INCLUDE_005fDIRS"></a>Library project: <strong>INCLUDE_DIRS</strong></dt>
<dd><p><code>xxx_INCLUDE_DIRS</code> is the list of additional directories that the
compiler will search when it is looking for include files; these flags
are specific to the <strong>xxx</strong> library, see
<a href="GNUmakefile_002epreamble.html#GNUmakefile_002epreamble">ADDITIONAL_INCLUDE_DIRS</a>, to see how to specify
additional global include directories.  The directories should be
specified as &lsquo;<samp>-I</samp>&rsquo; flags to the compiler.  The additional include
directories will be placed before the normal GNUstep and system include
directories, and before any global include directories specified with
<code>ADDITIONAL_INCLUDE_DIRS</code>, so they will always be searched first.
Replace the <strong>xxx</strong> with the name of the library as listed by the
<code>LIBRARY_NAME</code> variable.
