This option controls the behavior of malloc when asked to return an allocation of zero size. Because some options depend on the settings of other options, some of the options listed here may not be displayed in your configuration. The name of the operating system or ABI used on the system. It is normally safe to leave this option unset. Use the same technique discussed earlier: Because there is only one Perl toolset, you will not need to evaluate different toolsets to figure out which one best suits your needs.

The make rules themselves are very much the same ones you would find in a standard, native Makefile. This package includes the utilities most often used to manipulate binary object files.

Wind River Linux Toolchain and Build System User’s Guide, – Wind River Knowledge Library

Note Older versions of uClibc provided a wrapper around various toolchain components that allowed you to build applications against uClibc without the need for a custom toolchain. Query network devices via the newer Netlink interface rather then the old ioctl interface.

Simon Cozens implemented the microperl build option, based on an idea by Ilya Zakhareivh. Although the binutils package is the leanest in terms of installation documentation, it is also the least likely to cause any problems. Crosstool is cmopile of a couple of shell ckmpile and data files used by those scripts. If you chose a specific target model in the Target Processor Type option, this field may be preset for you. Enable support for keeping the user password in a shadow file, separate from the master user database, for better security.


Often, just searching or browsing the archive will immediately help you locate answers to your questions. Crosstool is a set of scripts that build and test several versions of GCC and glibc for most architectures supported by glibc.

Diet libc has now been installed in the proper directory. For this reason, it is preferable to exit your GUI, completely log out, and then log back in. Enable these options to display verbose error messages and signal descriptions at the cost of about 3. Set this to a subdirectory under your project build-tools directory.

[meta-networking] samba: add PACKAGECONFIG for valgrind

The combination of component versions used in the example toolchain build in the following section has been taken mostly from this resource. So, the Winfriver library also affects the size of application executable files and other libraries.

Useful for targets with no FPU, and preferred over using Linux-kernel-based emulation on these systems for performance reasons.

The uClibc library originates from the uClinux project, which provides a Linux that runs on processors lacking a memory management unit MMU.

The file contains the information needed to configure Crosstool for a specific architecture. Sign up using Facebook. Even so, most applications that can be compiled against the GNU C library will also compile and run using uClibc. As our last step, therefore, we will create a shortcut by making a soft link from the tools directory to the bin directory of the toolchain:. These options enable support for very rarely used aliases to the argv[0] argument containing a program name.


Ptxdist is organized around the concept of a projecta set of configuration files and patches required to build a certain set of software. Strips symbols from object files.

The next chapter discusses building the target filesystem. Your configure arguments are not right for cross-compilation. This sample of enhancements gives you an idea of what prebuilt environments offer. Pick a threading library implementation.

The platform project directory must not exist on an NFS mount. By using an NFS-mounted root filesystem, the target can access as much storage space as the server allows. However, as we said earlier, there are known file transfer problems between minicom and at least one bootloader, so it may not be right for you.

Hence, you could alter the steps and set up the Linux headers right before the C library setup. Now pick a sample toolchain to build from the included examples.

In addition, because Eclipse is a Java-based application, it can be deployed on a Windows platform just as easily as on Linux.
