I installed clamav from dvd. updated via online-update. I downloaded source for patched clamav .7. ran configure on clamav .7 source installed zlib-devel re-ran configure on clamav .7 source sucessfully copied clamdmail to source dir ran ./install (as per INSTALL file) I get clamdmail.c: In function `clamdscan': clamdmail.c:89: warning: cast to pointer from integer of different size clamdmail.c:154: warning: assignment makes pointer from integer without a cast clamdmail.c:184: error: dereferencing pointer to incomplete type clamdmail.c:184: error: dereferencing pointer to incomplete type clamdmail.c: In function `spoolstdin': clamdmail.c:296: error: `mprintf_stdout' undeclared (first use in this function) clamdmail.c:296: error: (Each undeclared identifier is reported only once clamdmail.c:296: error: for each function it appears in.) clamdmail.c: In function `printtag': clamdmail.c:442: error: `mprintf_stdout' undeclared (first use in this function) clamdmail.c: In function `help': clamdmail.c:458: error: `mprintf_stdout' undeclared (first use in this function) make: *** [clamdmail.o] Error 1 I assume that the installed (patched) version I have is for amd64 and the sourceforge version of clamdmail is for 32bit. Is this true? Is there a 64bit version of clamdmail? Is the solution to un-install re-install clamav as 32bit for compatability with clamdmail? Or is there a quick fix/patch for amd64 - clamdmail B-)
