NAME
cheatmake - fool make into not rebuilding certain files
SYNOPSIS
cheatmake [hidechangefile] [show] [whyfile]
DESCRIPTION
cheatmake is used to save time when recompiling. It can fool make into
skipping files that haven't changed in a meaningful way. This can be
used for instance when you change a comment in a file but none of the
actual code.
This utility is part of the KDE Software Development Kit.
OPTIONS
hidechange file
Hides the fact that file was changed by setting the timestamp
into the past. Use with care!
show Lists what files make currently needs to rebuild
why file
Explains why make must rebuild file
ENVIRONMENT
One of the following variables (but not both) should be set if the
source directory is different from the build directory. If the build
directory is simply a subdirectory of the source directory, the simpler
variable OBJ_SUBDIR should be used.
OBJ_SUBJDIR
Indicates that the build directory is in the given subdirectory
of the source directory. For instance, if the source directory
is kdesdk and the build directory is kdesdk/obj-i386-linux, then
OBJ_SUBDIR should be set to obj-i386-linux.
OBJ_REPLACEMENT
A sed expression that is used to transform the source directory
into the build directory. For instance, if the source directory
is kdesdk/obj-i386-linux, then OBJ_REPLACEMENT should be set to
s#kdesdk#kdesdk-obj#.
