| 28 | ### SOD_CHECK([ACTION-IF-LIBRARY-FOUND], [ACTION-IF-LIBRARY-NOT-FOUND]) | |
| 29 | ### | |
| 30 | ### Check that (a) the sod(1) translator and (b) the `libsod' library are | |
| 31 | ### available. | |
| 32 | ### | |
| 33 | ### If sod(1) can't be found, this isn't a problem: we assume that the | |
| 34 | ### generated output files are included in the distribution, and use a fake | |
| 35 | ### definition which will report an error if the files need rebuilding, as a | |
| 36 | ### poor person's version of the `missing' script. | |
| 37 | ### | |
| 38 | ### If the library can't be found, we have a more serious problem. The | |
| 39 | ### default behaviour is to (let `PKG_CHECK_MODULES') report a fatal error, | |
| 40 | ### but packages can override this behaviour by setting ACTION-IF-LIBRARY- | |
| 41 | ### NOT-FOUND to something non-empty. If the library /is/ found then do | |
| 42 | ### ACTION-IF-LIBRARY-FOUND; the default is to add the necessary compiler | |
| 43 | ### flags to `AM_CFLAGS'. (You are expected to make your own arrangements to | |
| 44 | ### link against `$SOD_LIBS'.) | |
