acpitool requires threads. However, it does not check for threads in its configure script, so forgets to link with -pthreads, so fails to build in static-only scenarii. However, upstream has been dead for the past 7+ years now, so there is not much point trying to fix this. Besides, a system with ACPI is most probably a biggish system, so shared libs will probably be enabled, so we just require shared libs. As for bfin, the cryptic configure failure: 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 in this specific case. However, this is a toolchain issue, as this does not occur for other toolchains. Still, inverting the call would anyway then cause 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 Again, because upstream is dead, there's not much point trying to fix this... And since there's not many chances that a bfin board has ACPI, we just disable acpitool for bfin.
