Subject: [PATCH] spawn: fix link error on uclibc
|
||
|
|
|
||
|
|
* m4/spawn_h.m4 (gl_HAVE_POSIX_SPAWN): use AC_SEARCH_LIBS,
|
||
|
|
to incorporate -lrt if needed (on uclibc for example).
|
||
|
|
* modules/posix_spawn: Reference the substituted LIB.
|
||
|
|
|
||
|
|
Patch status: upstream (gnulib commit d6eab2e70fc5ccc82a73e5c988b76a229e4cd3d5)
