Problems with cross-compiling
I've been using Yocto, which does cross-compiling. It has support for compiling LTP, but I've noticed it has a couple of patches. I found that one patch was needed for actually compile LTP, which applies to the file utils/Makefile.
The patch is for an older version of LTP, but I re-implemented it for the new version. Looking at the following rule:
$(FFSB): $(abs_srcdir)/$(FFSBDIR)
mkdir -p $(FFSBDIR)
cd $(FFSBDIR) && "$^/configure" && $(MAKE) top_srcdir="$^" allThis calls configure without parameters, which is most likely wrong for a cross-compile environment. It is this configure that fails. By simple removing it, everything works within Yocto.
Is there any reason for keeping this configure here? Or should I make a patch for removing it?
Regards
Mats Liljegren

The ffsb configure should be called from the top-level configure the same way it's done for the realtime directory.
Does following work for cross-compilation?
1. Remove the configure from the Makefile
2. Add AC_CONFIG_SUBDIRS([utils/ffsb-6.0-rc2]) into the configure.ac
3. Regenerate top level configure by make autotools
4. ./configure && make

PATCH 1/1 utils/Makefile: Move ffsb configure to configure.ac
I have now tried moving configure call from utils/Makefile to configure.ac, and it compiles both natively as well as a cross-compile. I also managed to start the fs_ext4 test case. Not sure whether this tells anything about ffsb since I'm not sure what it is, but it looked like it was related to ext4.

PATCH 1/1 utils/Makefile: Move ffsb configure to configure.ac
The configure call was done from make file without appropriate parameters, which breaks cross-compiling. Include ffsb into configure.ac so that it is included in the main configure call.
This fix is based on a patch by Fathi Boudra <[email protected]> for an earlier version of LTP.
