Question

在boost-libs（link to cvs repo）的源代码安装过程中，我在包管理器make中使用的bmake（pkgsrc）的长输出结束时得到以下内容我使用）和构建似乎失败了：

...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，在数千条输出行（full output）中，重复出现了一些错误行。我只是除了一些（他们不会像以下一样背靠背发生）：

```

已经构建并安装了其他boost相关的软件包（即boost-headers，boost-jam，boost-docs，boost-build）。 boost-python失败，但我认为这不是依赖。

使用QNX 6.5.0 SDP SP1

谢谢。

更新）回应@Igor R的评论。在许多stdint.h中找到了这样的内容：

# 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

我intleast8_t中定义了/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假设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/usr/include/stdint.h中看到的内容，QNX已经弃用了这些类型，现在只有在定义了__EXT_QNX时才定义它们。因此，以下针对boost/cstdint.hpp的临时补丁可能有所帮助：

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QNX版本的标准类型是什么，并定义更强大的条件。

boost-libs无法构建
