====== Daniel Verkamp: Automated regression testing ====== ===== Journal Week 3 ===== ==== Monday, June 8 ==== mkbootfs build on hold for now, since even rebuilding uClibc with the RPC setting enabled does not satisfy the mkbootfs busybox build; switching to detailed test descriptions until I get uclibc working properly. Worked on instructions for testing [[:soc:2009:dverkamp:notes:windows_xp_iscsi|Windows XP boot from iSCSI]] in QEMU, which seems to work up until the first actual boot from iSCSI, where Windows boots to the point of showing the desktop background image, then blue-screens: http://drv.nu/temp/qemu-winxp-iscsi-bsod.png I am considering attempting the procedure with real hardware instead of QEMU to see if that makes a diference. Update: Followed same procedure on real hardware, and the end result worked fine. Seems to be some problem with QEMU in that case; will investigate further as time allows, but for now, the real hardware test is working fine. ==== Tuesday, June 9 ==== Wrote detailed [[:soc:2009:dverkamp:notes:windows_pe|WinPE]] setup instructions. ==== Wednesday, June 10 ==== Continued debugging mkbootfs build; current uClibc wrapper script looks like this: export PATH=~/src/buildroot/buildroot-2009.05/build_i686/staging_dir/usr/bin:$PATH export CROSS_COMPILE=i686-linux-uclibc- export CC=i686-linux-uclibc-gcc $@ However, this still breaks during the install phase of busybox's build; somehow, unprefixed ''gcc'' is used instead of the cross-targeted gcc, resulting in an attempt to link with glibc instead of uClibc. Compilation before this point is using the correct cross gcc (''i686-linux-uclibc-gcc''). make -C busybox install make[1]: Entering directory `/home/daniel/src/mkbootfs/mkbootfs/busybox' rm -f .kernelrelease echo 1.9.0.svn > .kernelrelease make -f scripts/Makefile.build obj=scripts/basic make -f scripts/Makefile.build obj=. make -f scripts/Makefile.build obj=scripts make -f scripts/Makefile.build obj=applets gcc -Wp,-MD,applets/.applets.o.d -std=gnu99 -Iinclude -Ilibbb -I/home/daniel/src/mkbootfs/mkbootfs/busybox/libbb -include include/autoconf.h -D_GNU_SOURCE -DNDEBUG -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -D"BB_VER=KBUILD_STR(1.9.0.svn)" -DBB_BT=AUTOCONF_TIMESTAMP -D_FORTIFY_SOURCE=2 -Wall -Wshadow -Wwrite-strings -Wundef -Wstrict-prototypes -Wold-style-definition -Wmissing-prototypes -Wmissing-declarations -Os -fno-builtin-strlen -finline-limit=0 -fomit-frame-pointer -ffunction-sections -fdata-sections -fno-guess-branch-probability -funsigned-char -static-libgcc -falign-functions=1 -falign-jumps=1 -falign-labels=1 -falign-loops=1 -march=i386 -mpreferred-stack-boundary=2 -Wdeclaration-after-statement -Wno-pointer-sign -D"KBUILD_STR(s)=#s" -D"KBUILD_BASENAME=KBUILD_STR(applets)" -D"KBUILD_MODNAME=KBUILD_STR(applets)" -c -o applets/applets.o applets/applets.c applets/applets.c:15:2: warning: #warning Static linking against glibc produces buggy executables applets/applets.c:16:2: warning: #warning (glibc does not cope well with ld --gc-sections). applets/applets.c:17:2: warning: #warning See sources.redhat.com/bugzilla/show_bug.cgi?id=3400 applets/applets.c:18:2: warning: #warning Note that glibc is unsuitable for static linking anyway. applets/applets.c:19:2: warning: #warning If you still want to do it, remove -Wl,--gc-sections applets/applets.c:20:2: warning: #warning from scripts/trylink and remove this warning. applets/applets.c:21:2: error: #error Aborting compilation. make[2]: *** [applets/applets.o] Error 1
