poco 1.3.2 build failure

[astricker@…]

The package fails to build with

make[1]: *** No rule to make target \
`/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.o',\
 needed by \
`/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_devel_poco/work\
/poco-1.3.2/XML/obj/Darwin/i386/debug_shared/AbstractContainerNode.o'.  Stop.

(wrap to multiple lines by me, marked with \ at end of line)

Somehow the wrong dependency /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.o is generated.

I noticed that the patch provided in /opt/local/var/macports/sources/rsync.macports.org/release/ports/devel/poco/files/patch-rules-deps-universal.diff is not applied. This solve the wrong dependency problem, but directly leads to the next problem during linking of tests with CppUnit. Various symbols from CppUnit cannot be resolved, while a CppUnit library is found. (No idea if it's the one provided with poco distribution or the one I've installed with ports myself).

It seems that there is something messed up with this port.

Note: I previously synced (port sync -d) and upgraded (port upgrade installed) macports. I also ran a cleanup for poco (port clean --all poco).

Please test again with poco 1.3.3p1.

[astricker@…]

I did test with 1.3.3p1 now (Portfile from subversion trunk).

The dependency problem is fixed.

The linking failure with CppUnit still remains while linking poco-1.3.3p1-all/Foundation/testsuite/bin/Darwin/i386/testrunner:

Undefined symbols:

Yeah, I found the link failure:

1. I've installed the cppunit port. Those libraries resides in /opt/local/lib.
2. poco comes with it's own CppUnit library (older/newer than macport one). This one gets compiled to $(LIBPATH)
3. as $(LINKFLAGS) contains /opt/local/lib and comes before $(LIBRARY) (in build/rules/exec), the installed libcppunit from port is found first

I found a solution requiring a modification to build/config/Darwin. I prepend $(LIBPATH) to $(LINKFLAGS). This gives first priority to own libraries, then to other port libraries.

Now poco builds successful.

Fixed in r50102. Thanks for contributing.
