Subject: [PATCH 3/6] cmake: do not try to run arithchk when cross-compiling to
|
||
|
|
generate sources
|
||
|
|
|
||
|
|
Instead, use a predefined arith.h if provided, or generate a default one.
|
||
|
|
|
||
|
|
The arithchk binary is still built (but not installed) to allow the user to
|
||
|
|
run it on its target and use it; so then allowing to build an optimized
|
||
|
|
blas library.
