Bug ID: 101389 Summary: Parallel build doesn't work Product: gcc Version: 12.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: modula2 Assignee: unassigned at gcc dot gnu.org Reporter: ro at gcc dot gnu.org Target Milestone: --- I initially tried the builds of the devel/modula-2 branch on both Solaris 11 and Linux/x86_64 in parallel mode (-j48/-j64/-j32). This failed like this make[5]: *** No rule to make target 'ASCII.lo', needed by 'libm2pim.la'. Stop. make[5]: Leaving directory '/var/gcc/gcc-12.0.0-20210708/11.4-gm2/i386-pc-solaris2.11/libgm2/libm2pim' make[4]: *** [Makefile:538: all] Error 2 ASCII.mod lives in gcc/m2/gm2-libs, but there's no ASCII.lo anywhere in the tree at this time. Running the build sequentially allows it to continue past this error.
