Thanks for your help, Andrew!

With what you told me, I was eventually able to figure out I needed to add the following rule to our custom set of rules:

# This is necessary in R3.15.x as a consequence of TDCT producing .db files directly
$(COMMON_DIR)/%.db$(RAW)$(DEP): $(COMMON_DIR)/%.db$(RAW)
        @$(RM) $@
        $(MSI3_15) -D $(DBFLAGS) -o $(COMMONDEP_TARGET) $< > $@

Although, I now get complaints about circular dependencies being dropped that I don't yet understand:

make[3]: Circular ../O.Common/bctest.db <- ../O.Common/bctest.db dependency dropped.

The build rules changed between 3.14 and 3.15 specifically for $(DEP) = .d files; previously we would create a .d file in the same rule as the target itself and the build didn’t worry if there was no .d file. Since 3.15 we have a separate set of rules for creating .d files – look for the rules for targets %.db$(RAW)$(DEP) in Base/configure/RULES.Db and make sure you have equivalents in your ruleset.

Note that 3.15 comes with a newer version of the msi program which was required to generate .d files. In the build this is referred to with $(MSI3_15) since the older msi $(MSI) from extensions is not compatible. The associated changes may be what you’re missing.

IIRC there were quite a lot of changes to the build system between 3.14 and 3.15, I hope you have looked at those while updating your ruleset.

HTH,

- Andrew
