From mboxrd@z Thu Jan 1 00:00:00 1970 From: Yann E. MORIN Date: Sun, 17 Jul 2016 19:56:00 +0200 Subject: [Buildroot] [PATCH] package/acpitool: not available for bfin Message-ID: <1468778160-32413-1-git-send-email-yann.morin.1998@free.fr> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net bfin is the only arch on which acpitool fails to build with the autobuilders: http://autobuild.buildroot.org/?reason=acpitool-0.5.1 http://autobuild.buildroot.org/results/802/802f6bbc74ad8e89b2bb6a2f592ac91ef9cd88e3/ http://autobuild.buildroot.org/results/d2c/d2c708fc2aa18ecfc368a4ce93400cfc44366102/ [...] The cryptic error message; configure: error: C++ compiler cannot create executables is due to the order in which AC_PROG_CXX and AC_PROG_CC are called. Calling AC_PROG_CC first fixes this error message. But then we get linking errors: /home/ymorin/dev/buildroot/O/host/usr/bin/bfin-linux-g++ -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os -o acpitool main.o acpitool.o ac_adapter.o toshiba.o asus.o thinkpad.o cpu.o battery.o freq.o -lgcc acpitool.o: In function `Has_ACPI(char*)': acpitool.cpp:(.text+0x1be): undefined reference to `_Unwind_Resume' acpitool.o: In function `Get_Kernel_Version(char*, int)': acpitool.cpp:(.text+0x2aa): undefined reference to `_Unwind_Resume' acpitool.o: In function `Set_Kernel_Version()': acpitool.cpp:(.text+0x43e): undefined reference to `_Unwind_Resume' acpitool.o: In function `Do_Fan_Info(int)': acpitool.cpp:(.text+0x60a): undefined reference to `_Unwind_Resume' acpitool.o: In function `Show_WakeUp_Devices(int)': acpitool.cpp:(.text+0x770): undefined reference to `_Unwind_Resume' acpitool.o:acpitool.cpp:(.text+0x9ca): more undefined references to `_Unwind_Resume' follow /home/ymorin/dev/buildroot/O/host/opt/ext-toolchain/bin/../lib/gcc/bfin-buildroot-linux-uclibc/6.1.0/../../../../bfin-buildroot-linux-uclibc/bin/ld: acpitool: hidden symbol `___udivsi3' in /home/ymorin/dev/buildroot/O/host/opt/ext-toolchain/bin/../lib/gcc/bfin-buildroot-linux-uclibc/6.1.0/libgcc.a(_udivsi3.o) is referenced by DSO /home/ymorin/dev/buildroot/O/host/opt/ext-toolchain/bin/../lib/gcc/bfin-buildroot-linux-uclibc/6.1.0/../../../../bfin-buildroot-linux-uclibc/bin/ld: final link failed: Bad value collect2: error: ld returned 1 exit status The last one of those (the hidden ___udivsi3 symbol) is mopst concerning, and even the unwind stuff is not trivial. Because there's not many chances that a bfin board has ACPI, we just disable acpitoll for bfin. Signed-off-by: "Yann E.
