# Description:
|
|
|
|
# All .cpp and .h files in the current directory and subdirectories
|
|
# are checked to see which include statements could be omitted without
|
|
# causing a build error. Many of these omissions would not be desired.
|
|
# For example, currently if you don't include Undo.h in Undo.cpp, there
|
|
# is no error because Undo.h is included in Cursor.h which is included
|
|
# in Undo.cpp. But clearly we do want to include Undo.h in Undo.cpp.
|
|
|
|
# The results are stored in header_check.sh.log
|
|

# Exclude common headers with regex

# LyX was compiled on exotic environments and these sometimes

# require headers not needed on win/linux. So check the logs before

# deleting "redundant" standard libraries, Qt headers or includes around
