【问题描述】：
我试图让 MongoDB 驱动程序在 ARM 平台上运行，但构建系统 SCons 拒绝我的 Boost 库。
我摆弄了 libpath、extrapath 和 extrapathdyn 的不同组合，但无济于事。
gwue@Anubis:~/mongo$ scons -j4 --cc=/home/gwue/armgcc/lin/bin/arm-xilinx-linux-gnueabi-gcc --cxx=/home/gwue/armgcc/lin/bin/arm-xilinx-linux-gnueabi-g++ --prefix=/tmp/mongo --sharedclient --use-system-boost --cpppath=/home/gwue/boost1_54 --libpath=/home/gwue/boost1_54/stage/lib --extrapathdyn=/home/gwue/boost1_54/stage/lib --full install-mongoclient
结果：
scons: Reading SConscript files ...

我像这样编译了 Boost 库：
./bootstrap.sh
./b2 --without-python --without-iostreams -j4 toolset=gcc-arm
user-config.jam 包含：
using gcc : arm : /home/gwue/armgcc/lin/bin/arm-xilinx-linux-gnueabi-g++ ;
该问题仅在尝试交叉编译时出现。使用 x86_64 库和编译器，一切正常。 我怀疑我的 ARM Boost 库本质上是坏的，因为我们已经在一个已经存在的项目中使用它们就好了。
关于如何说服 scons 接受这些库的任何想法？
【问题讨论】：
-
我认为在您
ed 的部分中，您删除了编译行（对 g++ 的实际调用）。通过检查编译行，我们可以查看是否使用了正确的库路径（-L）。你能告诉我们编译输出吗？ -
我在问题取消前添加了最后几行。据我所知，scons 甚至没有尝试链接。
