GOA provides version information, primarily useful in configure

Packit Service |
c6b9b0 |
Checks that the GOA library in use is compatible with the

|
Packit Service |
c6b9b0 |
given version. Generally you would pass in the constants
|
|
Packit Service |
c6b9b0 |
GOA_MAJOR_VERSION, GOA_MINOR_VERSION, GOA_MICRO_VERSION
|
|
Packit Service |
c6b9b0 |
as the three arguments to this function; that produces
|
|
Packit Service |
c6b9b0 |
a check that the library in use is compatible with
|
|
Packit Service |
c6b9b0 |
the version of GOA the application or module was compiled
|
|
Packit Service |
c6b9b0 |
against.
|
|
Packit Service |
c6b9b0 |
Compatibility is defined by two things: first the version
|
|
Packit Service |
c6b9b0 |
of the running library is newer than the version
|

Packit Service |
c6b9b0 |
required_major

c6b9b0 |
.required_minor
|
|
Packit Service |
c6b9b0 |
.required_micro
|
|
Packit Service |
c6b9b0 |
. Second
|
|
Packit Service |
c6b9b0 |
the running library must be binary compatible with the
|
|
Packit Service |
c6b9b0 |
version required_major
