Subject: [PATCH] configure: fix AC_CHECK_LIB usage
|
|
|
483b06 |
|
|
|
483b06 |
Replace empty string with a single space in the third argument of
|
|
|
483b06 |
`AC_CHECK_LIB` (`action-if-found`) where applicable.
|
|
|
483b06 |
|
|
|
483b06 |
Empty string in the argument causes `AC_CHECK_LIB` to use the default
|
|
|
483b06 |
action when a library is found which includes adding the library to `LIBS`,
|
|
|
483b06 |
which specifies libraries to be linked in every binary and library in the
|
|
|
483b06 |
project.
|
|
|
483b06 |
|
|
|
483b06 |
This fixes libkrad, liblber, libldap_r and libsss_nss_idmap being linked to
|
|
|
483b06 |
every binary and library in IPA, even where unused.
