Hi John, That works - to an extent. gcc fails and the current configuration is: -Werror -Wdeclaration-after-statement -Wno-pointer-sign -D_FORTIFY_SOURCE=2
Configure doesn't fail, but that the flags are far fewer than earlier. Is this, what we want to go ahead with? If anyone wants to look at the changes in macros/m4_ax_check_compile_flag.m4 and configure.ac, I have pushed the changes to master repo on my github (https://github.com/bhardwajs/gnucash). Cheers, Sumit P.S. - Apologies for a two-month hiatus. Work drained a lot of time and energy. Should be better now. :) On Sun, Jul 6, 2014 at 1:05 AM, John Ralls <jra...@ceridwen.us> wrote: > > On Jul 5, 2014, at 11:34 PM, Sumit Bhardwaj <bhardw...@gmail.com> wrote: > > > Sure, John.
