Hi, My distcc server and client are configured to communicate through a reversed SSH tunnel. See [1]. In this setup, dev-util/strace-4.13 is failing to build with : > ioctlsort0.o: file not recognized: File format not recognized 1. https://wiki.gentoo.org/wiki/Talk:Distcc#Another_SSH_usage_example Reproducible: Always #

the build doesn't care how your compiler is configured. if your system is producing bad objects, then you should track that down. if you need help triaging your system, please try the forums or the gentoo-user mailing list. if you're also using ccache, try clearing your caches on all sides.
I do not use ccache anywhere. And yes, the build system sets a specific compiler to build ioctlsort.c. Please see the following commands : > # pwd > /var/tmp/portage/dev-util/strace-4.13/work/strace-4.13 > > # grep AX_PROG_CC_FOR_BUILD configure.ac > AX_PROG_CC_FOR_BUILD > > # grep CC_FOR_BUILD Makefile.am > ioctlsort_CC = $(CC_FOR_BUILD) > > # grep CC_FOR_BUILD Makefile > CC_FOR_BUILD = gcc > ac_ct_CC_FOR_BUILD = gcc > ioctlsort_CC = $(CC_FOR_BUILD) So, strace is unable to cross-compile (and distcc is finally not the problem).
(In reply to Fab from comment #3) the strace behavior is correct -- it needs to compile & run ioctlsort locally. it doesn't install it. we should change it to use $(tc-getBUILD_CC) explicitly so it uses a better default than just `gcc`.
i've pushed this rework: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=2201dbb7de7aaf045761d78735a445cecca16f44 can you see if that makes a difference for you ?

Yes, builds fine with distcc up now : > Dec 24 12:23:49 coreI5 distccd[3307]: (dcc_job_summary) client: 127.0.0.1:52320 COMPILE_OK exit:0 sig:0 core:0 ret:0 time:1959ms armv7a-hardfloat-linux-gnueabi-gcc ./ioctlsort.c Thank you.
