Subject: Fix cross compilation problem in parse-types.sh
X-Git-Tag: v1.42.10~25
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=91f04685bfa86ed4b19a54d11b4093b9d904f3df;p=thirdparty%2Fe2fsprogs.git

Fix cross compilation problem in parse-types.sh

The checking of types in parse-types.sh doesn't make much sense in a
cross-compilation environment, because the generated binary is
executed on build machine.

So even if asm_types.h has got correct statements for types, it's
possible that the generated binary will report an error, because these
types are for the target machine.
