Created attachment 579610 [details] emerge --info swh-lv2 I'm in process of world rebuild with new toolchain (all latest, except gcc is still 7.3.0), swh-lv2 failed to build due to missing object files (obviously not made due to make parallelization). First attempt failed at gverb-swh (meaningful excerpt from build log): x86_64-pc-linux-gnu-gcc plugins/gverb-swh.lv2/plugin.o -shared -lm -O2 gverb/gverbdsp.o gverb/gverb.o -o plugins/gverb-swh.lv2/plugin.so x86_64-pc-linux-gnu-gcc: error: gverb/gverbdsp.o: No such file or directory make: *** [Makefile:83: plugins/gverb-swh.lv2/plugin.so] Error 1 Second - at bandpass_a_iir-swh (which succeed at previous attempt): x86_64-pc-linux-gnu-gcc plugins/bandpass_a_iir-swh.lv2/plugin.o -shared -lm -O2 util/iir.o -o plugins/bandpass_a_iir-swh.lv2/plugin.so x86_64-pc-linux-gnu-gcc: error: util/iir.o: No such file or directory make: *** [Makefile:83: plugins/bandpass_a_iir-swh.lv2/plugin.so] Error 1 Looking at first log for more mentions of util/iir.o, it may be found in very begining: x86_64-pc-linux-gnu-gcc -Wall -I. -Iinclude -fPIC -DPIC -DFFTW3 -O2 -march=native -fomit-frame-pointer -pipe -fno-delete-null-pointer-checks -Wno-error -Wno-error -Wno-error -Wno-error -Wno-error util/iir.c -c -o util/iir.o In makefiles both missing files are mentioned as LDFLAGS in extra.mk. Sorry to some gcc options spam - just don't want unexpected fails due to hardcoded -Werror :).

Created attachment 579614 [details] build log (second attempt)
I made experiments with various make -j and -l options, and it seems only some -lx -jy combinations trigger the failure. Yet when I did it with fresh git copy (24 commits since release), it failed only at util/iir.o. failed combinations: -j3 -l1.8 -j3 -l3 -j10 -l3 (I have only 2 cores) while these are working: -jN (any N) -j3 -l5 -j2 -l1
