Subject: [PATCH] configure.ac: use pow() instead of matherr() for libm check
|
||
|
|
|
||
|
|
In certain configurations of uClibc, the matherr() function may not be
|
||
|
|
provided by the C library, which makes the current configure.ac check
|
||
|
|
for libm fail. However, iprutils does not use matherr(), so using this
|
||
|
|
function for the test makes little sense.
|
||
|
|
|
||
|
|
This patch adjusts configure.ac to test for pow() instead, which is
|
||
|
|
actually used by iprutils, and more commonly available, including in
|
||
|
|
uClibc.
