preserve toolchain

Hello mailinglist,

For a shorter development cycle I like to preserve the toolchain generated by buildroot for the next run. I naivly copied the output/toolchain to some other directory and set the toolchain directory in the buildroot config. The bin-directory does not include the gcc-binaries. Do I have to create links in the bin-directory to the gccs?

Is it possible to take the same toolchain for package build the next time? Can I recycle the toolchain generated by buildroot?

Thanks for any reply.

Regards,
Marcus

I used to try to do that, and had many problems with it. As a result, I switched to using crosstool-ng to build the toolchain.

I managed to do it, but it required a number of customizations to the external toolchain makefile, and there were still some minor issues that required work-arounds in a shell-script that I was using to do builds. I eventually gave up and heeded the advice of the
maintainers: now I use crosstool-ng to build my external toolchain.

Using crosstool-ng to build an external toolchain is the normal way of accomplishing what you want to accomplish.
