Hi, I ran into a slight difficulty with shared libraries on IBM AIX systems using libtool 2.2.6 (I'm not even sure if this is really where I should be asking questions about this)
If I have a main Fortran routine containing a common block and call a Fortran subroutine in a shared library also referencing this common block, the values in the common block were not being inherited in the subroutine (Fortran common blocks across shared libraries may not be ideal, but I was testing something out thinking about libltdl). I did however find that manually adding -brtl to LDFLAGS allowed this to work. The documentation I had available stated that -brtl is used to "determine which algorithm will be used to find libraries", however there was more info on the ibm site which cleared up some confusion for me. Should libtool be adding this flag, or is this something I should be manually adding via AM_LDFLAGS? Every other aspect of the shared library build is handled fine by libtool. If anyone has any suggestions on this I would be grateful to hear them. A secondary problem (while trying to do something particularly non-standard I suspect) was to access Fortran common blocks from within shared library C routines, but that does not appear to be anything to do with libtool. If anyone is interested I have available a cut down test case to duplicate what happens.
