Hi, after having worked around the "apparent CFLAGS mismatch" problem, I hitanother cross-compilation error while trying to build cyrus-sasl in buildroot:
$ make cyrus-sasl-dirclean $ make cyrus-sasl 2>&1 | tee cyrus-sasl.log [...]/home/murray/devel/buildroot/output/host/usr/bin/ccache /home/murray/devel/buildroot/output/host/usr/bin/arm-linux-gcc -Wall -W -Os -pipe -Os -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -o makemd5 makemd5.o -lresolv
rm -f md5global.h ./makemd5 md5global.h /bin/bash: ./makemd5: cannot execute binary file make[3]: *** [md5global.h] Error 126 [...]The problem here is pretty clear: makemd5, which is meant to run on the host,
has been cross-compiled instead: $ file output/build/cyrus-sasl-2.1.24rc1/include/makemd5output/build/cyrus-sasl-2.1.24rc1/include/makemd5: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.31, not stripped
Attached is my patch to allow makemd5 to correctly (non-cross) compiled. Basically, it consists in replacing $(CC) with $(HOSTCC) in cyrus-sasl's include/Makefile.in. Note that I'm not the first that faced this problem. My patch has been inspired by: http://tech.dir.groups.yahoo.com/group/nslu2-linux/message/4044?var=0 The build log is attached too. Luca
