Summary - mbedtls: building with ccache: /staging_dir/host/bin/ccache: invalid option -- 'd'
Task Type - Build Failure
Category - Toolchain
Status - Unconfirmed

Operating System - All
Severity - Very Low
Priority - Very Low
Reported Version - Trunk
Due in Version - Undecided
Due Date - Undecided
Details - I am currently trying to compile OpenWRT for

  CONFIG_TARGET_LANTIQ=Y
  CONFIG_TARGET_LANTIQ_XWAY=Y
  CONFIG_TARGET_lantiq_xway_DEVICE_arcadyan_arv752dpw22=y

I am using

  CONFIG_DEVEL=y
  CONFIG_CCACHE=y

I am building in the following way:

The build was carried out on a ''git clone git://github.com/openwrt/openwrt.git'', later brought up to date with a ''git pull'', with latest commit from 2018-03-05T10:44:20+01:00, commit hash 5cbd22bb0f.

Into this ''git clone'' a previously generated .config seed, made previously by ''make menuconfig'' and ''./scripts/diffconfig.sh'', was copied over to ''./.config''.

>From there on, the following commands were issued:

  ./scripts/feeds update -a
  ./scripts/feeds install -a
  make -j1 V=s defconfig
  make -j1 V=s download
  make -j1 V=s IGNORE_ERRORS=m | tee make.log

When it comed to building mbedtls, there are the following lines of output which indicate something is wrong:

  [...]
  make[3]: [Makefile:75: /home/felics/download/router/OS/OpenWRT/source_build/source/batch_builds/2018-02-26_12-04-45_-_custom-wo-pie_feeds-rooter-custom/build_dir/target-mips_24kc_musl/mbedtls-2.7.0/.configured_68b329da9893e34099c7d8ad5cb9c940] Error 123 (ignored)
  [...]
  /home/felics/download/router/OS/OpenWRT/source_build/source/batch_builds/2018-02-26_12-04-45_-_custom-wo-pie_feeds-rooter-custom/staging_dir/host/bin/ccache: invalid option -- 'd'
  Usage:
      ccache [options]
  [...]

Build continues, (seemingliy) successfully: Indicated by the further output of ''make'', and issuing later a ''make -j1 V=s'' (i.e. without ''IGNORE_ERRORS=m''), does not bring this up again.

The toolchain (''./staging_dir/toolchain-*'') is ''mips_24kc_gcc-5.5.0_musl''.

Build is carried out on an x86_64 Arch Linux machine.

Attached are the following files:

  * ''.config-diffconfig-seed'': The .config-seed used for make defconfig,
  * ''.config'': The ''.config'' created by the make defconfig and used for the build,
  * ''mbedtls.log'': The pa[.config-diffconfig-seed.txt](https://github.com/openwrt/packages/files/1782373/default.config-diffconfig-rt of the output of ''make -j1 V=s IGNORE_ERRORS=m'' regarding building mbedtls,
  * ''make.log.stdout.xz'': For your interest, the full output of ''make -j1 V=s IGNORE_ERRORS=m'' (.xz compressed; decompresses to about 29 MB) (Note that at the end another build error occurs, which seems not to be related to embedtls),
  * ''feeds.conf'': The ''feeds.conf'' used.

(Note that I just forgot to capture stderr too, but the error messages seem to be present in stdout. Since a full rebuild takes a day on my machine, I won't do that if not necessary.)

One or more files have been attached.
