[gentoo-dev] problems crosscompiling libXt

[David Thomas]

Hey all,

Here is a fix for libXt, similar to the problems I had with libX11 
last week.  I don't see an obvious way to patch the Makefile.am.
Please send comments.

Symptom:
../util/makestrs -i ..  < ../util/string.list > StringDefs.c
/bin/sh: ../util/makestrs: cannot execute binary file
make[2]: *** [StringDefs.c] Error 126

For this to work, have a look at the ebuild in the forwarded msg.

yeah, no good ... you need to add logic for a CC_FOR_BUILD which would
then be used to compile the helper programs like makestrs
