Hi Jeremy,About your said "Also, if it is possible to get it working, is there a way to resume from the point where the build failed? Since it took 10 hours to get there..."
several tricks to save time when build crosstool-ng: in ct-ng menuconfig, to config like this: 1.use multiple thread compile Paths and misc options (4) Number of parallel jobs 4 means 4 threads to compile crosstool-ng about thread number: "A good rule of thumb is twice the number of processors you have." here my cpu is Intel two core, so use 4. 2.resume from fail step Paths and misc options [*] Debug crosstool-NG [*] Save intermediate steps how to restore fail step, then continue build: basic logic is: ct-ng last_successful_step+ detail is : (1) see existing steps CLi@PC-CLI-1 ~/develop/crosstool-ng/crosstool-ng-1.18.0_build $ ct-ng list-steps Available build steps, in order: - libc_check_config - companion_libs_for_build - binutils_for_build - companion_libs_for_host - binutils_for_host - cc_core_pass_1 - kernel_headers - libc_start_files - cc_core_pass_2 - libc - cc_for_build - cc_for_host - libelf_for_target - binutils_for_target - debug - test_suite - finish Use "<step>" as action to execute only that step. Use "+<step>" as action to execute up to that step. Use "<step>+" as action to execute from that step onward. (2) when fail, let's say, on step cc_core_pass_1 so last successful step is: binutils_for_host so, after you fix problem, then do: ct-ng binutils_for_host+ so can restore binutils_for_host, then continue compile3.use interactive shell when fail -> when error, can fix error then continue build
Paths and misc options [*] Debug crosstool-NG [*] Interactive shell on failed commands then: when build fail, will show a interactive shell, like this: ...... [ERROR] >> Error happened in: CT_DoExecLog[scripts/functions@257][ERROR] >> called from: do_kernel_install[scripts/build/kernel/linux.sh@112] [ERROR] >> called from: do_kernel_headers[scripts/build/kernel/linux.sh@91]

exited with error code: 2 Please fix it up and finish by exiting the shell with one of these values: 1 fixed, continue with next build command 2 repeat this build command 3 abort build ct-ng:~/develop/crosstool-ng/crosstool-ng-1.18.0_build> then, after you fix error, let's say, vi to edit the xxx.c to fix some bug, then do: exit 2 to re-run the last fail command, to continue compile your xxx.c then can go through, can continue build. more detailed explain can refer my tutorial:(note: written in Chinese, you can use google translate to english if necessary)

As mentioned in a previous message, I am trying (for complicated reasons) to build a PowerPC compiler to run under Cygwin. Previously, recent versions of Crosstool-NG wouldn't build at all on my system. Thanks to Albert Dorrington for linking this patch which allowed crosstools to build: http://sourceware.org/ml/crossgcc/2012-05/msg00012.html I ran 'ct-ng menuconfig' and set my target to be PowerPC, turned off debug facilities, and basically used defaults for everything else. I also used eglibc (I think it was already selected by default). However, running 'ct-ng build' still failed with an error. Here's the output: $ ct-ng build [INFO ] Performing some trivial sanity checks [INFO ] Build started 20130701.085943 [INFO ] Building environment variables [INFO ] ================================================================= [INFO ] Retrieving needed toolchain components' tarballs [INFO ] Retrieving needed toolchain components' tarballs: done in 1190.11s (at 20:24) [INFO ] ================================================================= [INFO ] Extracting and patching toolchain components [32:18] / Useless use of /d modifier in transliteration operator at /usr/share/automake-1.9/Automake/Wrap.pm line 60.
