QT版本:qt-x11-free-3.3.8

操作系统:HP-UX at-vl02 B.11.31 U ia64 3890095976 unlimited-user license

编译器:aCC

现象:QT程序调用mmap函数时，会提示空间不够错误!!

解决方法:

1、在aCC编译时,CXXFLAGS和LFLAGS 加-N选项。

-N             Cause the output file from the linker to be marked as                     unshareable.  For details and system defaults, see                     ld(1).

2、在aCC编译时,LFLAGS 加+s, +b选项（chatr所必须）

-s             Cause the output of the linker to be stripped of symbol                     table information.  See strip(1) for more details.  The                     use of this option prevents the use of a symbolic                     debugger on the resulting program.  Also see ld(1) for                     additional details.      -b             Causes the linker ld(1) to create a shared library                     rather than a normal executable file.  Object files                     processed with this option must contain position                     independent code (PIC).  For details see ld(1), HP-UX                     Linker and Libraries Online User's Guide and the                     Programming on HP-UX manual.

3、执行"chatr +as mpas 生成的可执行文件名"

chatr_ia: chatr - change program's internal attributes on Integrity systems

4、正确执行后，可看到的结果有一行为:

address space model: MAPS

而不是

address space model: default
