Tim, Darrell, All, python-tqt fails to build from source. It looks like it may be related to a sip problem (see 1st two lines below). I haven't changed my build scripts of either sip or python-tqt. What should I check? Full error follows: sip: TQ_LONG is undefined Error: Unable to create the C++ code. This is the GPL version of PyTQt 3.18.1 (licensed under the GNU General Public License) for Python 2.7.3 on linux2. Type 'L' to view the license. Type 'yes' to accept the terms of the license. Type 'no' to decline the terms of the license. Do you accept the terms of the license? qextscintillaglobal.h could not be found in /opt/tqt3/include and so the qtext module will not be built.
