Below is a list of available configuration settings. The corresponding
environment variable name is indicated in parentheses after each configuration
-setting key. Boolean options are indicated with ``[boolean]''

*base_dir* (*CCACHE_BASEDIR*)::
--

-*compression* (*CCACHE_COMPRESS*) [boolean]::
+*compression* (*CCACHE_COMPRESS* or *CCACHE_NOCOMPRESS*, see <<_boolean_values,Boolean values>> above)::
If true, ccache will compress object files and other compiler output it
puts in the cache. However, this setting has no effect on how files are
compiled, but that sometimes doesn't work. For example, when using the
``aCC'' compiler on HP-UX, set the cpp extension to *i*.
-*direct_mode* (*CCACHE_DIRECT*) [boolean]::
+*direct_mode* (*CCACHE_DIRECT* or *CCACHE_NODIRECT*, see <<_boolean_values,Boolean values>> above)::
If true, the direct mode will be used. The default is true. See
<<_the_direct_mode,THE DIRECT MODE>>.
-*disable* (*CCACHE_DISABLE*) [boolean]::
+*disable* (*CCACHE_DISABLE* or *CCACHE_NODISABLE*, see <<_boolean_values,Boolean values>> above)::
When true, ccache will just call the real compiler, bypassing the cache
completely. The default is false.
the hash sum that idetifies the build. The list separator is semicolon on
Windows systems and colon on other systems.
-*hard_link* (*CCACHE_HARDLINK*) [boolean]::
+*hard_link* (*CCACHE_HARDLINK* or *CCACHE_NOHARDLINK*, see <<_boolean_values,Boolean values>> above)::
If true, ccache will attempt to use hard links from the cache directory
when creating the compiler output rather than using a file copy. Using hard
compressed cache files. This means that you should not enable compression
if you want to use hard links. The default is false.
-*hash_dir* (*CCACHE_HASHDIR*) [boolean]::
+*hash_dir* (*CCACHE_HASHDIR* or *CCACHE_NOHASHDIR*, see <<_boolean_values,Boolean values>> above)::
If true, ccache will include the current working directory in the hash that
is used to distinguish two compilations. This prevents a problem with the
<<_using_ccache_with_other_compiler_wrappers,USING CCACHE WITH OTHER
COMPILER WRAPPERS>>.
-*read_only* (*CCACHE_READONLY*) [boolean]::
+*read_only* (*CCACHE_READONLY* or *CCACHE_NOREADONLY*, see <<_boolean_values,Boolean values>> above)::
If true, ccache will attempt to use existing cached object files, but it
will not to try to add anything new to the cache. If you are using this
because your ccache directory is read-only, then you need to set
*temporary_dir* as otherwise ccache will fail to create temporary files.
-*read_only_direct* (*CCACHE_READONLY_DIRECT*) [boolean]::
+*read_only_direct* (*CCACHE_READONLY_DIRECT* or *CCACHE_NOREADONLY_DIRECT*, see <<_boolean_values,Boolean values>> above)::
Just like *read_only* except that ccache will only try to retrieve results
from the cache using the direct mode, not the preprocessor mode. See
documentation for *read_only* regarding using a read-only ccache directory.
-*recache* (*CCACHE_RECACHE*) [boolean]::
+*recache* (*CCACHE_RECACHE* or *CCACHE_NORECACHE*, see <<_boolean_values,Boolean values>> above)::
If true, ccache will not use any previously stored result. New results will
still be cached, possibly overwriting any pre-existing results.
-*run_second_cpp* (*CCACHE_CPP2*) [boolean]::
+*run_second_cpp* (*CCACHE_CPP2* or *CCACHE_NOCPP2*, see <<_boolean_values,Boolean values>> above)::
If true, ccache will not use the optimisation of avoiding the second call
to the preprocessor by compiling the preprocessed output that was used for
See the discussion under <<_troubleshooting,TROUBLESHOOTING>> for more
information.
-*stats* (*CCACHE_STATS*) [boolean]::
+*stats* (*CCACHE_STATS* or *CCACHE_NOSTATS*, see <<_boolean_values,Boolean values>> above)::
If true, ccache will update the statistics counters on each compilation.
The default is true.

the object files created from your compilations.
-*unify* (*CCACHE_UNIFY*) [boolean]::
+*unify* (*CCACHE_UNIFY* or *CCACHE_NOUNIFY*, see <<_boolean_values,Boolean values>> above)::
If true, ccache will use a C/C++ unifier when hashing the preprocessor
output if the *-g* option is not used. The unifier is slower than a normal
output, which contains data from the old header file; the wrong object file
is stored in the cache.)

Some settings are boolean values (i\&.e\&. truth values)\&. In a configuration file, such values must be set to the string \fBtrue\fR or \fBfalse\fR\&. For the corresponding environment variables, the semantics are a bit different: a set environment variable means \(lqtrue\(rq regardless of the value (even if set to the empty string), and an unset environment variable means \(lqfalse\(rq\&. Each boolean environment variable also has a negated form starting with \fBCCACHE_NO\fR\&. For example, \fBCCACHE_COMPRESS\fR can be set to force compression and \fBCCACHE_NOCOMPRESS\fR can be set to force no compression\&.

+Below is a list of available configuration settings\&. The corresponding environment variable name is indicated in parentheses after each configuration setting key\&.
.PP
\fBbase_dir\fR (\fBCCACHE_BASEDIR\fR)
.RS 4
.RE
.RE
.PP
-\fBcompression\fR (\fBCCACHE_COMPRESS\fR) [boolean]
+\fBcompression\fR (\fBCCACHE_COMPRESS\fR or \fBCCACHE_NOCOMPRESS\fR, see Boolean values above)
.RS 4
If true, ccache will compress object files and other compiler output it puts in the cache\&. However, this setting has no effect on how files are retrieved from the cache; compressed and uncompressed results will still be usable regardless of this setting\&. The default is false\&.
.RE
\fBi\fR\&.
.RE
.PP
-\fBdirect_mode\fR (\fBCCACHE_DIRECT\fR) [boolean]
+\fBdirect_mode\fR (\fBCCACHE_DIRECT\fR or \fBCCACHE_NODIRECT\fR, see Boolean values above)
.RS 4
If true, the direct mode will be used\&. The default is true\&. See
THE DIRECT MODE\&.
.RE
.PP
-\fBdisable\fR (\fBCCACHE_DISABLE\fR) [boolean]
+\fBdisable\fR (\fBCCACHE_DISABLE\fR or \fBCCACHE_NODISABLE\fR, see Boolean values above)
.RS 4
When true, ccache will just call the real compiler, bypassing the cache completely\&. The default is false\&.
.RE
This setting is a list of paths to files that ccache will include in the the hash sum that idetifies the build\&. The list separator is semicolon on Windows systems and colon on other systems\&.
.RE
.PP
-\fBhard_link\fR (\fBCCACHE_HARDLINK\fR) [boolean]
+\fBhard_link\fR (\fBCCACHE_HARDLINK\fR or \fBCCACHE_NOHARDLINK\fR, see Boolean values above)
.RS 4
If true, ccache will attempt to use hard links from the cache directory when creating the compiler output rather than using a file copy\&. Using hard links may be slightly faster in some situations, but can confuse programs like \(lqmake\(rq that rely on modification times\&. Another thing to keep in mind is that if the resulting object file is modified in any way, this corrupts the cached object file as well\&. Hard links are never made for compressed cache files\&. This means that you should not enable compression if you want to use hard links\&. The default is false\&.
.RE
.PP
-\fBhash_dir\fR (\fBCCACHE_HASHDIR\fR) [boolean]
+\fBhash_dir\fR (\fBCCACHE_HASHDIR\fR or \fBCCACHE_NOHASHDIR\fR, see Boolean values above)
.RS 4
If true, ccache will include the current working directory in the hash that is used to distinguish two compilations\&. This prevents a problem with the storage of the current working directory in the debug info of a object file, which can lead ccache to give a cached object file that has the working directory in the debug info set incorrectly\&. This option is off by default as the incorrect setting of this debug info rarely causes problems\&. If you strike problems with GDB not using the correct directory then enable this option\&.
.RE
USING CCACHE WITH OTHER COMPILER WRAPPERS\&.
.RE
.PP
-\fBread_only\fR (\fBCCACHE_READONLY\fR) [boolean]
+\fBread_only\fR (\fBCCACHE_READONLY\fR or \fBCCACHE_NOREADONLY\fR, see Boolean values above)
.RS 4
If true, ccache will attempt to use existing cached object files, but it will not to try to add anything new to the cache\&. If you are using this because your ccache directory is read\-only, then you need to set
\fBtemporary_dir\fR
as otherwise ccache will fail to create temporary files\&.
.RE
.PP
-\fBread_only_direct\fR (\fBCCACHE_READONLY_DIRECT\fR) [boolean]
+\fBread_only_direct\fR (\fBCCACHE_READONLY_DIRECT\fR or \fBCCACHE_NOREADONLY_DIRECT\fR, see Boolean values above)
.RS 4
Just like
\fBread_only\fR
regarding using a read\-only ccache directory\&.
.RE
.PP
-\fBrecache\fR (\fBCCACHE_RECACHE\fR) [boolean]
+\fBrecache\fR (\fBCCACHE_RECACHE\fR or \fBCCACHE_NORECACHE\fR, see Boolean values above)
.RS 4
If true, ccache will not use any previously stored result\&. New results will still be cached, possibly overwriting any pre\-existing results\&.
.RE
.PP
-\fBrun_second_cpp\fR (\fBCCACHE_CPP2\fR) [boolean]
+\fBrun_second_cpp\fR (\fBCCACHE_CPP2\fR or \fBCCACHE_NOCPP2\fR, see Boolean values above)
.RS 4
If true, ccache will not use the optimisation of avoiding the second call to the preprocessor by compiling the preprocessed output that was used for finding the hash in the case of a cache miss\&. This is primarily a debugging option, although it is possible that some unusual compilers will have problems with compiling the preprocessed output, in which case this option could allow ccache to be used anyway\&.
.RE
for more information\&.
.RE
.PP
-\fBstats\fR (\fBCCACHE_STATS\fR) [boolean]
+\fBstats\fR (\fBCCACHE_STATS\fR or \fBCCACHE_NOSTATS\fR, see Boolean values above)
.RS 4
If true, ccache will update the statistics counters on each compilation\&. The default is true\&.
.RE
This setting specifies the umask for ccache and all child processes (such as the compiler)\&. This is mostly useful when you wish to share your cache with other users\&. Note that this also affects the file permissions set on the object files created from your compilations\&.
.RE
.PP
-\fBunify\fR (\fBCCACHE_UNIFY\fR) [boolean]
+\fBunify\fR (\fBCCACHE_UNIFY\fR or \fBCCACHE_NOUNIFY\fR, see Boolean values above)
.RS 4
If true, ccache will use a C/C++ unifier when hashing the preprocessor output if the
\fB\-g\fR

The
\fB__TIME__\fR
-preprocessor macro is (potentially) being used\&. ccache turns off direct mode if \(lq__TIME__\(rq is present in the source code outside comments and string literals\&. This is done as a safety measure since the string indicates that a

The
\fB__FILE__\fR
