Hi. We are having som problems building our rootfs now that our custom distro (based on poky-tiny) no longer includes wide character support in libc. Here is an example of the errors we get:
| arm-poky-linux-gnueabi-libtool: link: arm-poky-linux-gnueabi-gcc -march=armv7-a -mthumb-interwork -mfloat-abi=softfp -mtune=cortex-a9 --sysroot=/home/qhanbec/poky/build/tmp/sysroots/zynq-zc706 -std=gnu99 -fsigned-char -fno-common -Wall -Werror=sequence-point -Wextra -Wmissing-declarations -Wmissing-parameter-type -Wmissing-prototypes -Wno-missing-field-initializers -Wredundant-decls -Wsign-compare -Wtype-limits -Wuninitialized -Wunused-but-set-parameter -Wunused-but-set-variable -Wunused-parameter -Wunused-result -Wunused-variable -O2 -pipe -g -feliminate-unused-debug-types -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed -o ul text-utils/ul.o -ltinfo | text-utils/rev.o: In function `main': | /home/poky/build/tmp/work/cortexa9-vfp-poky-linux-gnueabi/util-linux/2.22.2-r3/util-linux-2.22.2/text-utils/rev.c:139: undefined reference to `fgetws' | /home/poky/build/tmp/work/cortexa9-vfp-poky-linux-gnueabi/util-linux/2.22.2-r3/util-linux-2.22.2/text-utils/rev.c:151: undefined reference to `fgetws' | /home//poky/build/tmp/work/cortexa9-vfp-poky-linux-gnueabi/util-linux/2.22.2-r3/util-linux-2.22.2/text-utils/rev.c:154: undefined reference to `wcslen' | /home/poky/build/tmp/work/cortexa9-vfp-poky-linux-gnueabi/util-linux/2.22.2-r3/util-linux-2.22.2/text-utils/rev.c:160: undefined reference to `putwchar' | /home/poky/build/tmp/work/cortexa9-vfp-poky-linux-gnueabi/util-linux/2.22.2-r3/util-linux-2.22.2/text-utils/rev.c:162: undefined reference to `putwchar' | collect2: error: ld returned 1 exit status The problem is that util-linux still thinks we have wide character support (from configure.ac): AC_COMPILE_IFELSE([AC_LANG_PROGRAM([[ #include <wchar.h> #include <wctype.h> #include <stdio.h> ]], [[ wchar_t wc; wint_t w; w = fgetwc(stdin); if (w == WEOF) exit(1); wc = w; fputwc(wc,stdout); ]])], [AC_DEFINE(HAVE_WIDECHAR,1,Do we have wide character support?) ]) Since no linking is performed due to x-compilation, all that this does is basically checking if wchar.h exists or not. And that is also were the problem is. Even if we have disabled wide character support in eglibc, the wchar.h header files is still copied to our sysroot!? Is that really how it should be when DISTRO_FEATURES_LIBC does not include 'libc-posix-clang-wchar libc-posix-wchar-io'? Here is our DISTRO_FEATURES (as reported by bitbake -e) and build environment: DISTRO_FEATURES="ipv4 usbhost usbgadget ${DISTRO_FEATURES_WIFI} libc-libm libc-crypt libc-utmp libc-getlogin libc-posix-regexp libc-inet libc-nis sysvinit largefile nfs" Build Configuration: BB_VERSION = "1.19.0" BUILD_SYS = "x86_64-linux" NATIVELSBSTRING = "SUSE-LINUX-11" TARGET_SYS = "arm-poky-linux-gnueabi" MACHINE = "zynq-zc706" DISTRO = "poky-chris" DISTRO_VERSION = "1.4+snapshot-20130917" TUNE_FEATURES = "armv7a vfp cortexa9" TARGET_FPU = "vfp" meta meta-yocto meta-yocto-bsp = "master:3b38c898a4647c6a639d0dbd416b0bbacbf278f5" meta-oe = "master:7c292ce28756824b1fa377d516aedd979fa41f19" Any ideas how what might be wrong here?
