brave enough, you can try and debug them. They are hidden behind CT_BROKEN,
which itself is hiddent behind EXPERIMENTAL.
+Re-building an existing toolchain |
+----------------------------------+
+
+If you have an existing toolchain, you can re-use the options used to build it
+to create a new toolchain. That needs a very little bit of effort on your side
+but is quite easy. The options to build a toolchain are saved in the build log
+file that is saved within the toolchain. crosstool-NG can extract those options
+to recreate a new configuration:
+ ct-ng extractconfig </path/to/your/build.log
+
+will extract those options, prompt you for the new ones, which you can later
+edit with menuconfig.
+
+Of course, if your build log was compressed, you'd have to use something like:
+ bzcat /path/to/your/build.log.bz2 |ct-ng extractconfig
+
