Hi Team,

I am compiling my C++ code with purify(7.0) in Solaris to find the memory leaks.

using make purify command,
It created the object files and purify object file both sucessfully, say for tcpclient.cc
tcpclient.o
tcpclient_pure_p9_c0_104192125_32.o

but later it gives linking error:

ld: warning: file /udir/Rational/releases/purify.sol.7.0/cache//omcws06/lib/libdl.so.1_pure_p3_c0_104192125_510_32: attempted multiple inclusion of file

I don't know why this linking error is coming.

Please help me in resolving this issue.

Thanks,
Henry

I think your cache contains mixed files. It means you have already used purify for another app with the same cache and something "strange" left in it. Try to remove everything from the cache and rebuild again. (you gave a very limited information, so probably my tip won't help, but otherwise you will need to give more info: what is the makefile, how do you build your app, what are the purify flags you set... )

Hi Pan,

Can you please tell me which cache you are talking about and how to clear that.

The Makefile has the following entry for purify:
purify::
$(VB2)purify_homedir=`$(PURIFY) -printhomedir`; \
if [ $$? != 0 ]; then $(ECHO) "ERROR : can't find $(PURIFY) in your path."; exit 1; fi; \
$(ECHO) "Using `$(PURIFY) -version` from $$purify_homedir"; \
$(MAKE) CXX="$(PURIFY) $(PURIFY_FLAGS) $(CXX)" CC="$(PURIFY) $(PURIFY_FLAGS) $(CC)" ALL_DEFINES="$(ALL_DEFINES) -I$$purify_homedir -DPURIFY_ON" PURIFY_LIBS="$$purify_homedir/purify_stubs.a"


Thanks,
Henry

this dir is a cache wich is used by purify: /udir/Rational/releases/purify.sol.7.0/cache. You can either move/remove the content or define another emtpy directory instead. Also I would like to know those PURIFY_FLAGS

Hi,

I deleted the contents from /udir/Rational/releases/purify.sol.7.0/cache directory, but still " attempted multiple inclusion of file " error comes.


I am not able to get the entry for PURIFY_FLAGS in Makefile.

It is kept as blank.
PURIFY_FLAGS =

Thanks,
Henry

run your build process with -v (so add -v flag to the command line) and copy the output here

Hi,

I have finally found the fix for this issue.

find . |xargs grep -il "libdl.so"

here more then 1 Makefile has this .so, so delete the .so entry from the not required Makefile and linking error will be gone.

Thanks,

P.S : Issue is solved.
