GNUPro

GNUPro is a commercial software?
GNUPro is Red Hat's commercial software development suite of tools that is built around the open source gnu standard. GNUPro products are tested, certified and produced as an integrated toolsuite specifically for commercial developers of both desktop and embedded products.
----不知道commercial software 和 free software冲突不冲突……不过从GNUPro的文档上看去，好像没有对GPL的条款附加什么，这让我很怀疑这段话的用意，郁闷……

继续看redhat公司的 服务支持页面，介绍GNUPro 产品家族►。应该可以放心使用GNUPro suite了：除了service，你可以自由的使用。而实际上我们只是把它当作各个平台下的编译工具来使用，不必担心生成的程序受到GPL“感染”，这算是FSF free software哲学下最仁慈的一面了。

GNUPro Developer Tools

Multi-platform Software Development Tools GNUPro Toolkit 04r2 Documentation

gnu-based development tools are critical for open source development. Red Hat employs the highest caliber tools engineering capability of any company to continually develop and extend the range of the standard gnu tools such as GCC, G++ and GDB. This product family is known as GNUPro.

In addition to the cross-development tools for embedded systems development, native versions of this technology has been ported to a wide range of Unix and Windows platforms and can substantially enhance the process of migrating from these platforms to Red Hat Enterprise linux.

Details of GNUPro

Red Hat GNUPro is the leading compiler/debugger tool suite of software developers worldwide. Red Hat is the premier provider of gnu technologies, designed for both desktop application development environments and embedded systems. GNUPro is an open-source C and C++ tool suite that contains the latest technology developed by expert Red Hat engineers, with enhancements and extensions contributed by open source developers from around the world.

GNUPro includes a compiler suite made up of the GNUPro C compiler, the GNUPro C++ compiler, and a range of additional tools and utilities, including the gnu assembler (gas), gnu linker (ld) for most platforms, and binary utilities (binutils). The compilation technology in the GNUPro toolsuite is based on the gcc project, an open source development project driving the leading edge in compiler technology.

GNUPro also includes the technology and tools for effective, efficient debug sessions. The standard command-line debugger, gdb, supports the same range of host systems and target microprocessors as gcc/g++. GDB allows the developer complete access to program state, including source and assembly level, variables, registers, and memory. In addition GNUPro also includes Simulators and the Insight graphical debugger. The tools are also compatible with the Eclipse IDE provided by Red Hat.

Red Hat delivers GNUPro for embedded or cross-platform developers through a value added subscription service, which entitles your team to the latest upgrades as they become available and access to Red Hat Open Source Support.
