Subject: [PATCH] configure.ac: add library if header found (#10)
|
|
|
|
If the pthread.h header is found, make sure library containing
|
|
"pthread_atfork" is added to the list of libraries against which to link.
|
|
On some hosts (e.g. openSUSE 15.1) "-lpthread" needs to be explicitly added
|
|
in order for the code to compile correctly.
