Re: [GNC-dev] Sample Report with Examples
Let me ask you, have you ever coded for a non-procedural language? If not, if scheme is your first, there is going to be learning curve, and much of your experience with procedural languages not as much help as you might think. I'd suggest you get an elementary LISP text (scheme is a dialect of LISP) But essentially. a) It is a functional language. Instead of carrying out some procedure you are evaluating some function*. A scheme (LISP) program is a function. To make matters worse, sometimes the result of the evaluation is irrelevant and what is wanted are "side effects" resulting form the evaluation. b) The fundamental data type is "list" c) Those top level definitions are the definitions of named functions that will be used in the main evaluation. Like in a procedural language you might define subroutines that would be called. BUT you can also "define on the fly" (a "lambda" function, not named, so only can be used in this place) Like I said, get an elementary LISP text and get well beyond the equivalent of :hello world" before you try to understand scheme Michael D Novack * The computer science among us will know that these can be proven equivalent (that's what LISP was all about originally). BTW, although c is usually used as a procedural language it can be used as a functional language. While learning c and on a list discussing what we were learning I got challenged to rewrite one of my exercises as a pure function (to convince me c could be used that way) PS: the 'nix users who are comfortable at the command line and writing scripts well your shell language plus library of standard utilities constitute a non-procedural language of fundamental data type "string". So what you learned doing that not completely useless. Also 'nix users who use Emacs/XEmacs, well you ARE in a LISP environment when you do that.

[GNC-dev] New warnings on cmake master - Fedora 36
Commit https://github.com/Gnucash/gnucash/commit/ fed4daf4e7dea7c85a56ad08f1817319272f7567 Added a number of boost libraries in the cmake check. Since that commit a cmake run will spew these warnings: CMake Warning at /usr/share/cmake/Modules/FindBoost.cmake:2217 (message): No header defined for algorithm; skipping header check (note: header-only libraries have no designated component) Call Stack (most recent call first): CMakeLists.txt:549 (find_package) CMake Warning at /usr/share/cmake/Modules/FindBoost.cmake:2217 (message): No header defined for asio; skipping header check (note: header-only libraries have no designated component) Call Stack (most recent call first): CMakeLists.txt:549 (find_package) CMake Warning at /usr/share/cmake/Modules/FindBoost.cmake:2217 (message): No header defined for process; skipping header check (note: header-only libraries have no designated component) Call Stack (most recent call first): CMakeLists.txt:549 (find_package) CMake Warning at /usr/share/cmake/Modules/FindBoost.cmake:2217 (message): No header defined for property_tree; skipping header check (note: header-only libraries have no designated component) Call Stack (most recent call first): CMakeLists.txt:549 (find_package) As the warning suggests, header only libraries shouldn't be added to FindBoost. That's at least the case on Fedora. Did you have problems with finding these header-only libraries on other platforms ?
