I have a makefile which makes either executables or a shared library.
i.e. make -f unix.mak will create the executables and
make -f unix.mak libolsv will create the shared library.
Since these have to be made i.e both executable and the shared library, I need to make the executables and then a clean ( make -f unix.mak cleanobj) and then make the shared library.
But I want to avoid the intermediate step of make -f unix.mak clean; i.e. the user should not do it explicitly. Is there any way I can include it in the rule for the shared library.
This is what I have.
This is what I have tried:
and also this
and I get the following error in both the cases:
gcc: OdbcSvApp.o: No such file or directory
gcc: SvSocket.o: No such file or directory
gcc: SvStmt.o: No such file or directory
gcc: SvOdbcWrapper.o: No such file or directory
gcc: OdbcCallReader.o: No such file or directory
gcc: MgrCalls.o: No such file or directory
gcc: OdbcSvProxy.o: No such file or directory
make: *** [libolsv20.so] Error 1
So how do I get around this. I want to include the clean rule in $(DAEMON_SO)

I can't seem to get a rule in my Makefile to ever run... even if I change the rule to force make to re-enter the rule, or if I change the dependent files the rule depends on. Any ideas why the second rule is being ignored here?
