For C and C++ files yes... But even with CDE currently, we do not use gcc -E, we directly call cpp and pass the output through sed scripts. And we preporocess many file types other than C/C++. tradcpp was designed as a portable replacement for Imake's use of cpp, which is pretty much everything, especially non-C/C++ files. It should build for all machines, and reduces our reliance on whatever compiler is in use. So you are not really missing anything - I just found calling one portable program easier/cleaner than using a cpp/sed pipeline. -jon > -mrt > > > > Original Message > > > > From: j...@radscan.com > Sent: November 1, 2019 6:48 PM > To: cdesktopenv-devel@lists.sourceforge.net > Subject: Re: [cdesktopenv-devel] [PATCH] [autotools-conversion] > > > On 10/23/19 4:23 PM, Jon Trulson wrote: >> On 10/23/19 4:18 PM, Chase wrote: >>> Most of it should work in theory™, but the most testing I did was to make >>> sure that we could get past the configure.ac file, but I made some changes >>> afterwards.
