我正在尝试在ARM平台上运行MongoDB驱动程序，但构建系统SCons拒绝我的Boost库。
我用libpath，extrapath和extrapathdyn的不同组合摆弄无济于事。
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++ ;
只有在尝试交叉编译时才会出现问题。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，因为我们已经在已经存在的项目中使用它们就好了。
关于如何说服scons接受libs的任何想法？
答案 0 :(得分：0)
我仍然无法让它发挥作用。 至少有一个没有依赖关系的纯实现http://docs.mongodb.org/ecosystem/drivers/c/。 这个编译很好，所以我们可能会采用它。
