Building sip4-tqt

Is sip4-tqt an interface layer or a full replacement to sip? I thought an interface layer yet I saw this in the build output: This is SIP 4.10.5 for Python 2.6.4 on linux2. sip-4.10.2 is installed on my system. I have TQt3 installed. I tried building sip4-tqt and saw the following failures: Creating sipconfig.py... Creating top level Makefile... Creating sip code generator Makefile... Creating sip module Makefile... make[1]: Entering directory `/dev/shm/sip4-tqt/sipgen' gcc -c -O2 -march=i486 -mtune=i686 -I/usr/include/tqt -I/usr/include/tqt3 -I/usr/include/qt3 -O2 -w -DNDEBUG -I. -o main.o main.c gcc -c -O2 -march=i486 -mtune=i686 -I/usr/include/tqt -I/usr/include/tqt3 -I/usr/include/qt3 -O2 -w -DNDEBUG -I. -o transform.o transform.c gcc -c -O2 -march=i486 -mtune=i686 -I/usr/include/tqt -I/usr/include/tqt3 -I/usr/include/qt3 -O2 -w -DNDEBUG -I. -o gencode.o gencode.c In file included from sip.h:26, from transform.c:24: /usr/include/tqt/tqt.h:54:23: error: ntqglobal.h: No such file or directory In file included from sip.h:26, from main.c:26: /usr/include/tqt/tqt.h:54:23: error: ntqglobal.h: No such file or directory In file included from sip.h:26, from gencode.c:27: /usr/include/tqt/tqt.h:54:23: error: ntqglobal.h: No such file or directory make[1]: *** [main.o] Error 1 make[1]: *** Waiting for unfinished jobs.... make[1]: *** [transform.o] Error 1 make[1]: *** [gencode.o] Error 1 make[1]: Leaving directory `/dev/shm/sip4-tqt/sipgen' make: *** [all] Error 2 Darrell
