I just built base 7.0.7 on Centos 7 with no changes to the files in configure/os.

 

My IOCs now are not built with libreadline, while in base 7.0.6.1 they were, again with no changes to the configure/os files.

 

I see this change between base 7.0.6.1 and base 7.0.7

The release notes say:

Automatic COMMANDLINE_LIBRARY w/ newer compilers

When built with a compiler supporting __has_include<>, the presence of the <readline/readline.h> will be used to automatically determine a default value for COMMANDLINE_LIBRARY.

Mingw builds with readline support now link -ltermcap instead of -lcurses.

This should not effect sites which set explicitly set COMMANDLINE_LIBRARY as the only definition in Base now has the form COMMANDLINE_LIBRARY ?= ....

I interpret the first sentence here to mean that the test for COMMANDLINE_LIBRARY is done in the compiler if possible, but it does not say that the previous way of doing it in the CONFIG_SITE file (for older compilers) has been removed

 

Does this mean that I now need to edit CONFIG_SITE.Common.linux-x86_64 to manually set COMMANDLINE_LIBRARY?

 

Thanks,
