mbedtls: building with ccache: /staging_dir/host/bin/ccache: invalid option -- 'd'

[mbedtls: building with ccache: /staging_dir/host/bin/ccache: invalid option -- 'd'] Tags: mbedtls; ccache; build;

Maintainer: ?? Environment: The toolchain (./staging_dir/toolchain-*) is mips_24kc_gcc-5.5.0_musl, OpenWRT version: git clone git://github.com/openwrt/openwrt.git with recent git pull, with latest commit from 2018-03-05T10:44:20+01:00, commit hash 5cbd22bb0f.

Description:

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.txt: The .config-seed used for make defconfig,
.config.txt: The .config created by the make defconfig and used for the build,
mbedtls.log.txt: The part of the output of make -j1 V=s IGNORE_ERRORS=m regarding building mbedtls,
make.log.stdout.gz: 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.txt: 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.)
