我的嵌入式设备有一个gcc 4.3.3工具链,但我没有python(并且不需要它).

我正在寻找一种无需python(编译和交叉编译)配置boostbuild的方法.

python是强制性的吗？

我必须编译每个单独的部分,但boost-python？(我希望不是).

提前致谢.

由于木星,我做了什么

./bootstrap.sh --without-libraries=python
./b2

我得到了

Component configuration:

    - chrono                   : building
    - context                  : building
    - date_time                : building
    - exception                : building
    - filesystem               : building
    - graph                    : building
    - graph_parallel           : building
    - iostreams                : building
    - locale                   : building
    - math                     : building
    - mpi                      : building
    - program_options          : building
    - python                   : not building
    - random                   : building
    - regex                    : building
    - serialization            : building
    - signals …

我有以下代码使用std :: list容器测试内存释放:

#include <iostream>
#include <list>
#include <string>

#include <boost/bind.hpp>

/* count of element to put into container
 */
static const unsigned long SIZE = 50000000;

/* element use for test
 */
class Element
{
public:
    Element()
    : mId(0)
    {}
    Element( long id )
    : mId(id)
    {}
    virtual ~Element()
    {
    }
    inline long getId() const
    {
        return this->mId;
    }

    inline bool operator<( const Element & rightOperand ) const
    {
        return this->mId < rightOperand.mId;
    }

    inline bool isEven() const
    { …

在我的项目中,有一个来自另一个项目的文件夹的符号链接.该文件夹的名称位于.cvsignore中

但是此文件夹(符号链接)包含来自其他项目的cvs元数据(CVS文件夹).

cvs命令没有问题,并忽略该文件夹.

但是eclipse想要同步它.

问题是,ecplise可以在同步时忽略文件夹,或者如何使eclipse尊重.cvsignore文件？

文件夹(符号链接)名称是共享的,在我的.cvsignore中包含一个带有它名称的行

我们使用符号链接技巧在我们的软件和单独构建的插件之间共享源代码(单独的autotools项目).

有没有办法用autotools(automake)来改变这条大线

进入这个

请注意,使用librsvg文件只是一个例子.

我看到了这个问题,但是对于Makefile编写者来说,Makefile.am编写器是否有解决方案

I am trying to use the Boost property trees to read INIfiles containing properties within sections have a "composed" path name.

For example my INIfile looks like this:

[my.section.subsection1]
someProp1=0

[my.section.subsection2]
anotherProp=1

I read it with the following code:

namespace pt = boost::property_tree;

pt::ptree propTree;
pt::read_ini(filePath, propTree);
boost::optional<uint32_t> someProp1 = pt.get_optional<uint32_t>("my.section.subsection1.someProp1");

The problem is that I never get the value of someProp1...

When I iterate over the first tree level I see the the entire section name …
