现象： 创建Makefile文件，但是出现如下错误（缺少popt库）： [root@localhost oprofile-0.9.3]# ./configure --with-kernel-support --target=arm-linux --host=arm-9tdmi-linux-gnu --build=i686-pc-linux-gnu --prefix=/work/OProfile/myOProfile checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for gawk... gawk checking whether make sets $(MAKE)... yes checking for arm-9tdmi-linux-gnu-strip... arm-9tdmi-linux-gnu-strip checking for arm-9tdmi-linux-gnu-ranlib... arm-9tdmi-linux-gnu-ranlib checking for arm-9tdmi-linux-gnu-gcc... arm-9tdmi-linux-gnu-gcc checking for C compiler default output file name... a.out checking whether the C compiler works... yes checking whether we are cross compiling... yes checking for suffix of executables... checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether arm-9tdmi-linux-gnu-gcc accepts -g... yes checking for arm-9tdmi-linux-gnu-gcc option to accept ANSI C... none needed checking for style of include used by make...

System requirements Linux kernel 2.2/2.4 OProfile uses a kernel module that can be compiled for 2.2.11 or later and 2.4. Versions 2.4.10 or above are recommended, and required if you use the boot-time kernel option nosmp. AMD Hammer support requires a recent (>= 2.4.19) kernel with the line EXPORT_SYMBOL(do_fork); present in kernel/ksyms.c. Such a kernel is present in the x86-64.org CVS repository. 2.5 kernels are supported with the in-kernel OProfile driver. modutils 2.4.6 or above You should have installed modutils 2.4.6 or higher (in fact earlier versions work well in almost all cases). Supported architecture For Intel IA32, a CPU with either a P6 generation or Pentium 4 core is required. In marketing terms this translates to anything between an Intel Pentium Pro (not Pentium Classics) and a Pentium 4 / Xeon, including all Celerons. The AMD Athlon, Duron, and Hammer CPUs are also supported. Other IA32 CPU types only support the RTC mode of OProfile; please see later in this manual for details. Hyper-threaded Pentium IVs are not supported in 2.4. For 2.4 kernels, the Intel IA-64 CPUs are also supported. For 2.5 kernels, there is additionally support for Alpha processors, and sparc64, ppc64, and PA-RISC in timer mode. Uniprocessor or SMP SMP machines are fully supported. Required libraries These libraries are required : popt, bfd, liberty (debian users: libiberty is provided in binutils-dev package), dl, plus the standard C++ libraries. Bash version 2 The opcontrol script requires bash version 2 at least to be installed as /bin/bash or /bin/bash2 OProfile GUI The use of the GUI to start the profiler requires the Qt 2 library. Qt 3 should also work. ELF Probably not too strenuous a requirement, but older A.OUT binaries/libraries are not supported. K&R coding style OK, so it's not really a requirement, but I wish it was...
