GnuCash Compiler Dependency
|
|
---------------------------
|
|
|
|
The GnuCash developers use gcc (http://gcc.gnu.org) for developing and
|
|
testing GnuCash. For convenience, we have relied on certain features
|
|
of gcc that are not part of any official standard and may not be
|
|
available with other standard-compliant compilers. Anyone desiring to
|
|
compile GnuCash with some other compiler may have to remove these
|
|
"gcc-isms", some of which are documented here.
|
|
|
|
Pointer-typed NULL sentinel values
|
|
----------------------------------
|
|
|
|
Gcc provides an implementation of `stddef.h' that defines NULL to
|
|
always expand to a pointer-typed null constant. This is precisely
|
|
what is needed in order to make sentinel value arguments to variadic
|
|
functions correct for both 32 and 64 bit platforms. However, another
|
|
implementation may define NULL to expand to `0'. In that case, all
|
|
sentinel value arguments must have an explicit `(void *)' cast.
|
|
|
|
C++ style comments
|
|
------------------
|
|
|
|
C++ style comments (`// comment to end of line') are discouraged but
|
|
not actively eradicated.
|
|
|
|
Variadic Macros
|
|
---------------
|
|
|
|
GnuCash uses variadic macros for debugging and logging support (via
|
|
qof).
|
|
|
|
Declarations after Code
|
|
-----------------------
|
|
|
|
The use of declarations after code (`int i; i = 0; char *foo;') is
|
|
strongly discouraged and actively removed whenever it's caught.
|
|
|
|
|
|

GnuCash Library Dependency Policy
|
|
---------------------------------
|
|
|
|
GnuCash desires to only depend on library versions and packages that are
|
|
practically available. Specifically, we choose to depend only on versions
|
|
that have been in the major distributions for 6 months. (This is motivated in
|
|
part by the 1.6 release, which required a large set of relatively-recent
|
|
dependencies. Specifically, as most user's (distributions) did not have the
|
|
required versions packaged, it was exceedingly painful for end users to
|
|
upgrade to the anticipated release, leading to a reputation that gnucash
|
|
still has.)
|
|
|
|
This document serves to keep track of the major distributions, the date of
|
|
their major release[s], and the relevant library versions as part of that
|
|
release (or an official package-upgrade path)
