I followed instructions and got the same error as above.
Grepping for IconButton, as suggested, does not find anything. That
is, the file moc_FancyLineEdit.cpp
is where it should, but it does not contain any ref to IconButton
Please, can you report the output of the following command?
$ which bc
For example, I get:
$ which bc
/usr/bin/bc
No output, I don't have that program installed, it seems.
What is it?
$ whatis bc
bc (1) - An arbitrary precision calculator language
bc (1posix) - arbitrary-precision arithmetic language
Install bc and it will work. It is used to get the Qt version in hex format from
the x.y.z decimal format and pass it to the moc compiler. Without bc you should
see moc invoked like this:
moc-qt4 -DQT_VERSION=0x0 -o moc_FancyLineEdit.cpp ...
Notice the -DQT_VERSION=0x0 flag, which should instead be something like
-DQT_VERSION=0x040704. So, moc would be instructed that you have Qt version
0.0.0
and thus some part of the sources are omitted from compilation.
Remember to remove the old moc_FancyLineEdit.cpp or to touch
src/frontends/qt4/FancyLineEdit.h before launching make.
Yes indeed, that's the reason: in ./src/frontends/qt4/Makefile you will find
QT_VERSION = $(shell IFS=.; set -- `echo $(QT4_VERSION)`; \
echo 0x0`echo "obase=16; $$1*65536+$$2*256+$$3" | bc`)
so no bc, no QT_VERSION. A very quick&dirty hack would be to edit the Makefile:
QT_VERSION = 0x040704
