2 | # URIPARSER_CHECK ([DEFAULT-ACTION], [MINIMUM-VERSION], | ||
3 | # [ACTION-IF-YES], [ACTION-IF-NO]) | ||
4 | # Checks for uriparser library. DEFAULT-ACTION is the string yes or no to | ||
5 | # specify whether to default to --with-uriparser or --without-liburiparser. | ||
6 | # If not supplied, DEFAULT-ACTION is yes. MINIMUM-VERSION is the | ||
7 | # minimum version of uriparser to accept. Pass the version as a regular | ||
8 | # version number like 0.8.5. If not supplied, any version is | ||
9 | # accepted. ACTION-IF-YES is a list of shell commands to run if | ||
10 | # uriparser was successfully found and passed the various tests. | ||
11 | # ACTION-IF-NO is a list of shell commands that are run otherwise. | ||
12 | # Note that using --without-uriparser does run ACTION-IF-NO. | ||
13 | # | ||
14 | # This macro #defines HAVE_URIPARSER if a working uriparser setup is | ||
15 | # found, and sets @URIPARSER@ and @URIPARSER_CPPFLAGS@ to the necessary | ||
16 | # values. | ||
17 | # | ||
18 | # Users may override the detected values by doing something like: | ||
19 | # URIPARSER="-luriparser" URIPARSER_CPPFLAGS="-I/usr/myinclude" ./configure | ||
