dnl Synopsis: mdw_CHECK_MANYLIBS(FUNC, LIBS, [IF-FOUND], [IF-NOT-FOUND]) |
| 261 |
dnl |
| 262 |
dnl Arguments: FUNC = a function to try to find |
| 263 |
dnl LIBS = a whitespace-separated list of libraries to search |
| 264 |
dnl IF-FOUND = what to do when the function is found |
| 265 |
dnl IF-NOT-FOUND = what to do when the function isn't found |
| 266 |
dnl |
| 267 |
dnl Use: Searches for a library which defines FUNC. It first tries |
| 268 |
dnl without any libraries; then it tries each library specified |
| 269 |
dnl in LIBS in turn. If it finds a match, it adds the |
| 270 |
dnl appropriate library to `LIBS'. |
| 271 |
dnl |
| 272 |
dnl This is particularly handy under DIREIX: if you link with |
| 273 |
dnl `-lnsl' then you get non-NIS-aware versions of getpwnam and |
| 274 |
dnl so on, which is clearly a Bad Thing. |
| 275 |
dnl |
| 276 |
dnl Modified: by Evgeny Stambulchik to add (found) libraries to `LIBS' |
| 277 |
dnl *only* if `IF-FOUND' is absent. As well, if no additional |
| 278 |
dnl library is needed for `FUNC', `mdw_cv_lib_$1' sets to "". |
