在boost-libs（链接到 cvs repo）的源代码安装期间，我在 bmake 的长输出（在我使用make的包管理器pkgsrc中使用）的最后得到以下内容，并且构建似乎失败：

...skipped <pbin.v2/libs/wave/build/gcc-4.4.2/release/link-static/threading-multi>libboost_wave.a for lack of <pbin.v2/libs/wave/build/gcc-4.4.2/release/link-static/threading-multi>instantiate_cpp_exprgrammar.o...
...skipped <pstage/lib>libboost_wave.a for lack of <pbin.v2/libs/wave/build/gcc-4.4.2/release/link-static/threading-multi>libboost_wave.a...
...failed updating 181 targets...
...skipped 280 targets...
*** Error code 1

Stop.
bmake: stopped in /usr/pkgsrc/devel/boost-libs
*** Error code 1

我注意到，在数以千计的输出行（完整输出）中，一些错误行反复出现。我只是除了一些（它们不会像下面那样背靠背发生）：

```

其他boost相关的包（即 boost-headers、boost-jam、boost-docs、boost-build）已经构建和安装。boost-python失败，但我认为这不取决于。

使用QNX6.5.0 SDP SP1

谢谢你。

更新）回应@Igor R 的评论。在许多stdint.h这样的发现中：

# find /usr -iname 'stdint.h'
/usr/share/pkgsrc/archivers/gtar-base/work/tar-1.26/gnu/stdint.h
/usr/qnx650/target/qnx6/usr/include/c++/4.4.2/tr1/stdint.h
/usr/qnx650/target/qnx6/usr/include/stdint.h
/usr/include/c++/4.4.2/tr1/stdint.h
/usr/include/stdint.h

在我看来，它intleast8_t的定义是/usr/include/stdint.h：

# more /usr/include/stdint.h
:
#if defined(__EXT_QNX)
/*
 * These types are deprecated and applications should use the
 * int_/uint_ types defined below.
 */
typedef _Intleast8t             intleast8_t;
typedef _Uintleast8t            uintleast8_t;

Boost 假定 QNX 定义了非标准类型名称：

#ifdef __QNX__

// QNX (Dinkumware stdlib) defines these as non-standard names.
// Reflect to the standard names.

typedef ::intleast8_t int_least8_t;
typedef ::intfast8_t int_fast8_t;

但是根据您在 中看到的内容/usr/include/stdint.h，QNX 已经弃用了这些类型，现在它们仅在定义时才__EXT_QNX被定义。因此，以下临时补丁boost/cstdint.hpp可能会有所帮助：

9 9   # endif 
10 10    
11    - #ifdef __QNX__ 
11    + #if defined(__QNX__) && defined(__EXT_QNX) 
12 12    
13 13   // QNX (Dinkumware stdlib) defines these as non-standard names.

然而，更好的方法是了解标准类型可用的 QNX 版本，并定义更稳健的条件。
