When emerging a package with distcc that uses autoconf and DISTCC_VERBOSE=1, generally get error like: /usr/lib/gcc/x86_64-pc-linux-gnu/9.3.0/../../../../x86_64-pc-linux-gnu/bin/ld:

After digging I found that a quick solution is to force -fPIC for the packages with problem with CFLAGS="${CFLAGS} -fPIC" CXXFLAGS="${CXXFLAGS} -fPIC" But for some packages it is not enought, I have to emerge without distcc. By digging further, I found that configure does not find -fPIC is working. Extract of configure output: checking for x86_64-pc-linux-gnu-gcc option to produce PIC... -fPIC -DPIC checking if x86_64-pc-linux-gnu-gcc PIC flag -fPIC -DPIC works... no checking if x86_64-pc-linux-gnu-gcc static flag -static works... no checking if x86_64-pc-linux-gnu-gcc supports -c -o file.o... no checking if x86_64-pc-linux-gnu-gcc supports -c -o file.o... (cached) no Looking in the configure script, I found that it is due to distcc output in verbose mode that perturbs configure script. configure interpret differences between 2 compilations outputs as due to errors. But outputs of distcc in verbose mode are different between several runs, as can be seen below. First distcc output used in configure as reference : distcc[12000] (dcc_trace_version) distcc 3.4 x86_64-pc-linux-gnu; built Oct 13 2021 16:15:47 distcc[12000] (dcc_recursion_safeguard) safeguard level=0 distcc[12000] (main) compiler name is "x86_64-pc-linux-gnu-g++" distcc[12000] (dcc_set_path) setting PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/opt/bin:/usr/lib64/opencascade-7.5.2/bin:/usr/lib/llvm/12/bin:/usr/lib/llvm/11/bin:/usr/lib/llvm/10/bin distcc[12000] (dcc_scan_args) scanning arguments: x86_64-pc-linux-gnu-g++ -c -m64 -O2 -march=k8 -mtune=k8 conftest.cpp distcc[12000] (dcc_scan_args) found input file "conftest.cpp" distcc[12000] (dcc_source_needs_local) autoconf tests are run locally: conftest.cpp distcc[12000] (dcc_get_hostlist) not reading /home/sylvain/.distcc/hosts: No such file or directory distcc[12000] (dcc_parse_hosts_file) load hosts from /etc/distcc/hosts distcc[12000] (dcc_parse_hosts) found tcp token "10.42.0.2/24,cpp,lzo" distcc[12000] (dcc_parse_options) got CPP option distcc[12000] (dcc_parse_options) got LZO option distcc[12000] (dcc_parse_hosts) found tcp token "10.42.0.1/12,cpp,lzo" distcc[12000] (dcc_parse_options) got CPP option distcc[12000] (dcc_parse_options) got LZO option distcc[12000] (dcc_lock_host) got cpu lock on localhost slot 0 as fd3 distcc[12000] exec on localhost: x86_64-pc-linux-gnu-g++ -c -m64 -O2 -march=k8 -mtune=k8 conftest.cpp distcc[12000] (dcc_note_state) note state 5, file "conftest.cpp", host "localhost" distcc[12000] (dcc_spawn_child) forking to execute: x86_64-pc-linux-gnu-g++ -c -m64 -O2 -march=k8 -mtune=k8 conftest.cpp distcc[12000] (dcc_spawn_child) child started as pid12001 distcc[12001] (dcc_increment_safeguard) setting safeguard: _DISTCC_SAFEGUARD=1 distcc[12000] (dcc_collect_child) cc child 12001 terminated with status 0 distcc[12000] (dcc_collect_child) cc times: user 0.000000s, system 0.000000s, 0 minflt, 0 majflt distcc[12000] compile conftest.cpp on localhost completed ok distcc[12000] (dcc_unlock) release lock fd3 distcc[12000] elapsed compilation time 0.009451s distcc[12000] (dcc_exit) exit: code 0; self: 0.000721 user 0.000000 sys; children: 0.007215 user 0.002086 sys distcc[12000] (dcc_cleanup_tempfiles_inner) deleted 0 temporary files Second output of distcc in configure to test -fPIC: distcc[12114] (dcc_trace_version) distcc 3.4 x86_64-pc-linux-gnu; built Oct 13 2021 16:15:47 distcc[12114] (dcc_recursion_safeguard) safeguard level=0 distcc[12114] (main) compiler name is "x86_64-pc-linux-gnu-g++" distcc[12114] (dcc_set_path) setting PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/opt/bin:/usr/lib64/opencascade-7.5.2/bin:/usr/lib/llvm/12/bin:/usr/lib/llvm/11/bin:/usr/lib/llvm/10/bin distcc[12114] (dcc_scan_args) scanning arguments: x86_64-pc-linux-gnu-g++ -c -m64 -O2 -march=k8 -mtune=k8 -fPIC -DPIC -DPIC conftest.cpp distcc[12114] (dcc_scan_args) found input file "conftest.cpp" distcc[12114] (dcc_source_needs_local) autoconf tests are run locally: conftest.cpp distcc[12114] (dcc_get_hostlist) not reading /home/sylvain/.distcc/hosts: No such file or directory distcc[12114] (dcc_parse_hosts_file) load hosts from /etc/distcc/hosts distcc[12114] (dcc_parse_hosts) found tcp token "10.42.0.2/24,cpp,lzo" distcc[12114] (dcc_parse_options) got CPP option distcc[12114] (dcc_parse_options) got LZO option distcc[12114] (dcc_parse_hosts) found tcp token "10.42.0.1/12,cpp,lzo" distcc[12114] (dcc_parse_options) got CPP option distcc[12114] (dcc_parse_options) got LZO option distcc[12114] (dcc_lock_host) got cpu lock on localhost slot 0 as fd3 distcc[12114] exec on localhost: x86_64-pc-linux-gnu-g++ -c -m64 -O2 -march=k8 -mtune=k8 -fPIC -DPIC -DPIC conftest.cpp distcc[12114] (dcc_note_state) note state 5, file "conftest.cpp", host "localhost" distcc[12114] (dcc_spawn_child) forking to execute: x86_64-pc-linux-gnu-g++ -c -m64 -O2 -march=k8 -mtune=k8 -fPIC -DPIC -DPIC conftest.cpp distcc[12114] (dcc_spawn_child) child started as pid12115 distcc[12115] (dcc_increment_safeguard) setting safeguard: _DISTCC_SAFEGUARD=1 distcc[12114] (dcc_collect_child) cc child 12115 terminated with status 0 distcc[12114] (dcc_collect_child) cc times: user 0.000000s, system 0.000000s, 0 minflt, 0 majflt distcc[12114] compile conftest.cpp on localhost completed ok distcc[12114] (dcc_unlock) release lock fd3 distcc[12114] elapsed compilation time 0.010154s distcc[12114] (dcc_exit) exit: code 0; self: 0.000000 user 0.000742 sys; children: 0.005493 user 0.003699 sys distcc[12114] (dcc_cleanup_tempfiles_inner) deleted 0 temporary files Solving cleanly this bug is out of my knowledge. I do not know if it is - distcc that must change where to output verbose information (if possible). - autoconf that must adapt to this distcc output - gentoo that can prevent the use of DISTCC_VERBOSE=1 when using distcc in portage (either in distcc or portage package) Setting DISTCC_VERBOSE=0 with sudo distcc-config --set-env DISTCC_VERBOSE 1 seems to solve the problem (I did not try to re-emerge all the concerned packages). I couldn't confirm if DISTCC_VERBOSE=1 is the default or not when installing distcc. As my understanding of the distcc ebuild it is default to 0, but it was set to 1 in /etc/env.d/02distcc, and I don't remember touching this file. I only modifyed /etc/systemd/system/distccd.service.d/00gentoo.conf that seems to be overriden by /etc/env.d/02distcc. In the meantime, it could be nice to prevent users in the wiki of distcc, as this problem concerns lots of packages. Best regards, Sylvain
I also opened a bug for distcc https://github.com/distcc/distcc/issues/441
Indeed it seems by default DISTCC_VERBOSE=0, and so no problem by default. I have changed it in /etc/env.d/02distcc I do not remember how and when. But current bug is still annoying if ones add DISTCC_VERBOSE=1 to see what happens when setting up distcc. Bug I reported in distcc have been closed as not seeing it as a bug of distcc. Conclusion I see is DISTCC_VERBOSE=1 should not be set for usual use of distcc with emerge. Only in case of distcc problems.
It sounds like you misconfigured your system, so closing this as invalid.
