modxslt-config1

Usage

Overview

modxslt-config can be used to query the status of an installed libmodxslt and to access its compile time parameters/options.

The main idea behind modxslt-config (or any other foo-config) is to provide an easy way for configre scripts and makefiles to use a given library. The configure script of a package using libmodxslt should try to search for modxslt-config, while the makefiles will try to compile the package using the variables found using the modxslt-config command.

Options

--prefix

Returns libmodxslt install prefix, as specified to the configure script

--exec-prefix

Returns libmodxslt install exec-prefix, as specified to the configure script

--libs

Returns the parameters to be used with ld to link your binaries with libmodxslt

--libtool-libs

Returns the parameters to be used with libtool to link your binaries with libmodxslt

--includes

Returns the parameters to be used with cc to allow your .c files to include libmodxslt headers

--cppflags

Returns the parameters to be used with cpp (the c preprocessor) to succesfully compile your .c files using libmodxslt headers

--cflags

Returns the parameters specified to cc during libmodxslt compilation

--list

modxslt-config allows you to access any other variable specified or detected by the libmodxslt configure script. This options lists all known varaibles and their raw values (with shell variables not substituted)

--query=VAR

shows the value of variable VAR, expanding any shell variables therein

--show=VAR

same as --query, but shell variables are not expanded

--version

Show version of libmodxslt installed on this system

If called without parameters, the help screen is displayed. More than one parameter can be specified at the same time.

Examples

$ modxslt-config --query=sysconfdir
/usr/local/etc
$ modxslt-config --show=sysconfdir
${prefix}/etc
$ modxslt-config --prefix
/usr/local
$ modxslt-config --cflags
-g -O2 -D_REENTRANT
$ cc `modxslt-config --includes` `modxslt-config --libs` \
  `modxslt-config --cppflags` myownprogram.c -o myownprogram

Return values

modxslt-config exits with status 1 in case no argument was supplied and the help screen was displayed. Status 2 is returned whenever an argument wich does not need any additional parameter is encountered with an unnecessary parameter (like --prefix=fuffa). Status 3 is returned when an argument which needs an additional parameter is encountered without the needed parameter (like --query), while 4 is returned when an unknown argument is specified. Any other exit status should be interpreted accordingly to the shell being used.
