你可能喜欢pgi fortran 安装的问题，感觉很奇怪
pgi fortran 安装的问题，感觉很奇怪
pgi fortran 5.2
提示出现如下错误pgf90-linux86-64: license manager problem:
&&failed to check out license
&&feature start data in the future
feature: pgf90-linux86-64
license path :/usr/pgi/license.dat:license.dat
flexlm error -31,34
我的环境变量什么都设置好了
别的机器都好用
就两台机器不好用
这是这么回事？
尤其是license path 那一行，很奇怪的。
清高手指点
装了好几次都这样。
license可以解为许可证。
许可证问题。
Linux或许只是美国人的一种非Windows的选择，因为微软是他们国家的。微软绝不会干危害美国国家安全的事，微软暴利也只是美国人把钱从一个口袋中转移到另一个口袋中而已。美国人在Linux问题上可以超然。中国人，你有超然的资本吗？

我也知道是这个问题啊
我安装了别的机器都没有问题
就这个有问题
license path :/usr/pgi/license.dat:license.dat
这一行有问题
正确的应该是：
license file :/usr/pgi/license.dat
license Path 应该是/usr/pgi
我删除的时候是直接删除/usr/pgi文件夹
是不是错误的安装导致的问题？
安装用./install安装的
真的感觉有问题
这种问题很难说的。
我只装过intel的fortran编译器。别的真是不知道。

没有人知道吗？
我怀疑是系统的问题
不知道怎么回事啊
pgi应该是很好安装的，用install安装到默认目录就可以了，关于环境变量的设置在安装目录下有一个设置，直接把其中两部分cp到用户目录下的 .bashrc文件的最后，修改就可以了，我这里只需将前面的%去掉就行了，不应该出现什么问题。
如果还有问题，请检查系统时间是否正确，与当前时间不符的系统时间可能会造成此类问题，还有就是检查license文件的读写权限PGI Visual Fortran 2010(Fortran编译器) 免费绿色版
世界领先的独立的高性能计算技术编译器及开发工具供应商Portland Group&(PGI)，PGI Visual Fortran&(PVF&)全面上市销售。PVF将 PGI的高性能64位及32位Fortran并行编译器及开发工具套件与Microsoft Visual Studio 2005整合在一起，为科学工作者和工程师从32位升级到64位Microsoft Windows平台提供一套高效的系统开发解决方案。
科研工作者将PGI编译器及开发工具广泛用于内置英特尔和AMD高性能微处理器的64位和32位 Linux工作站、服务器和集群器上。该版软件使Portland Group对运行在Windows平台上的64位和32位Fortran应用程序的开发支持扩展到英特尔和AMD的64位和32位微处理器，新软件运行在深受市场欢迎的Microsoft Visual Studio 2005集成开发环境(IDE)。PGI Visual Fortran 套件整合了多种兼容性能，使从现有的支持Windows的32位Fortran升级到64位平台变得十分简单，具体兼容功能包括支持Windows 32位应用编程接口(API)、调用规则、汇编命令以及公认的标准实用工具库。
Microsoft Visual Studio是世界上应用最广泛的集成开发环境。Visual Studio 2005工具及技术（ 包括一个并行调试器 ）使开发人员可以利用他们现有的Windows开发技能及经验开发在Windows Compute Cluster Server 2003平台上运行的HPC（高性能计算）应用程序。
PGI Visual Fortran包括最新版的PGI本机OpenMP，以及支持FORTRAN77和Fortran95编程语言的自动并行化编译器，主要特性包括一整套:
由面向Fortran的文本编辑器、Fortran本征函数提示和选择关键字组成的Visual Studio Fortran项目系统；
Fortran 应用程序自定义创建引擎；
自定义调试引擎，提供Fortran所需的语言专用调试功能；
支持单线程、多线程及OpenMP并行应用程序调试；
兼容Microsoft Visual C++ 2008；
支持调试PGI Fortran和Visual C++ 2005的混合应用程序
PGI的编译器及开发工具都具有如下特性：完全本机支持OpenMP并行编程扩展、在多核心处理器上的自动并行化、完全支持64位寻址、本机集成标量和矢量SSE/SSE2/SSE3代码生成，以及PGI 世界领先的优化基础设施。
PGI Visual Fortran是为64位的AMD64和英特尔的EM64T及32位的x86处理器高度优化的，其创建PGI Unified Binary&的功能是业内独一无二的。PGI Unified Binary&是一个能够在两个处理器平台上运行的可执行文件，内含针对AMD64和EM64T处理器优化的代码序列。PGI Unified Binary使独立软件开发商(ISV)和自定义应用程序开发人员认识到一个64位平台的优点，同时还能充分利用英特尔和AMD公司开带来的最新创新技术

Parallel Fortran Compilers and Tools for Microsoft Windows
PGI Visual Fortran& (PVF&) brings the PGI suite of high-performance 64-bit and 32-bit parallel Fortran compilers to Microsoft* Windows* developers using Microsoft Visual Studio*.
High-performance PGI Compilers PVF features the latest version of PGI's native OpenMP and auto-parallel Fortran compilers. PGI compilers are supported on and can generate fully optimized code for a broad range of popular high-performance computing platforms including 64-bit x64 and 32-bit x86 processor-based systems.
PGI Fortran compilers offer world-class performance and features including both automatic and OpenMP 3.0 parallelization support for optimizing performance on multi-core processors. State-of-the-art compiler technologies found in PVF include vectorization, parallelization, interprocedural analysis, memory hierarchy optimization, cross file function inlining, CPU-specific optimization and more. PGI Unified Binary& technology streamlines cross-platform support by combining into a single executable file code optimized for any number of different x64 processors.
PVF augments the Visual Studio debugger by adding a Fortran language specific custom debug engine. The PVF debug engine supports debugging of single and multi-thread, OpenMP, multi-thread MSMPI and hybrid MSMPI+OpenMP Fortran applications. It enables debugging of 64-bit or 32-bit applications using source code or assembly code, and provides full access to the registers and hardware state of the processors. Other multi-process MSMPI capabilities include Visual Studio property pages for configuring compile-time options, launching applications either locally on a workstation or on a distributed-memory Windows HPC Server 2008 cluster system, and debugging of programs running either locally or on a cluster.
Visual Studio Integration
PVF includes features to enable rapid code development. PVF adds syntax coloring, Fortran intrinsics tips and keyword completion to the Visual Studio editor. PVF includes a complete Fortran build environment for Visual Studio with Fortran specific features such as automatic build dependency management. PVF is interoperable with Microsoft Visual C++ so Fortran sub-programs can call C functions and vice versa. PVF includes a number of DVF/CVF compatibility features including full support for the Win32 API. Sample projects include building Fortran dialog boxes, console and Windows applications, DLLs and static libraries.
PVF augments the Visual Studio debugger with a custom debug engine that provides Fortran language specific debugging capability. The PVF debug engine supports debugging of single-thread, multi-thread, and OpenMP applications. It enables debugging of 64-bit or 32-bit applications using source code or assembly code, and it provides full access to the registers and hardware state of the processor. The PVF debug engine can debug executable files built for native Windows, Windows Subsystem for UNIX-based Applications (SUA) and Windows Services for UNIX (SFU). The PVF debug engine is interoperable with the Visual C++.
A Complete Fortran Development Solution PGI Visual Fortran includes the Visual Studio 2008 Shell&&a complete stand-alone Windows Fortran development environment. No additional software is required. PVF also supports existing installations of Visual Studio 2008, Visual Studio 2005 or both.
Documentation includes the PVF User's Guide, PVF Release Notes, PVF Installation Guide and the PGI Fortran Language Reference manual. The PVF User's Guide and PGI Fortran Reference are also part of the Visual Studio help system.
License options include single user node-locked and multi-user network floating. Compiling 64-bit applications requires a 64-bit Windows operating system (e.g. Microsoft Windows Vista, Microsoft Windows Server 2003 x64 Edition or Microsoft Windows XP Professional x64 Edition).
