Re: edm and other extensions on 64-bit SL machines

Hi Pierrick,

If your configuration configure/* contains entries like X11_LIB=/usr/lib 
then the linker will search in the wrong path on a 64 bit system.
If you want to use the same configuration files for both, 64 and 32 bit 
systems, you need separate files for linux-x86 and linux-x86_64. In 
configure/CONFIG_EXTENSIONS I have these lines:
include $(TOP)/configure/RELEASE
-include $(TOP)/configure/RELEASE.$(EPICS_HOST_ARCH)

This allows me to put X11_LIB=/usr/lib into RELEASE but 
X11_LIB=/usr/lib64 into RELEASE.linux-x86_64
Regards,
Dirk
