Compiling Qt in Linux: Unable to compile moc.cpp

[paulocarvalho_br_2009]

People, during compilation of Qt 4.8.5 in a Linux RHE 5.0 64-bit there goes the following linking command:


gmake[1]: Entering directory `/Work/ur5m/qt4.8.5/src/tools/moc'
gcc -g -m64 -Wl,-Bdynamic -Wl,-u,___pseudo_link -L/usr/lib64 -Wl,-rpath,/usr/lib64 -Wl,-rpath-link,/Work/ur5m/qt4.8.5/lib -Wl,-O1 -Wl,-rpath,/Work/ur5m/qt4.8.5_install/lib -Wl,-rpath,/Work/ur5m/qt4.8.5_install/lib -o ../../../bin/moc release-shared/moc.o release-shared/preprocessor.o release-shared/generator.o release-shared/parser.o release-shared/token.o release-shared/main.o****-L/Work/ur5m/qt4.8.5/src/tools/bootstrap -lbootstrap -lz -lz

I put four red asterisks to mark four suspicious spaces in the configure-generated Makefile command, possibly indicating some environment variable left blank or something alike. But what?

The command fails with these linking error messages:

Please, help!

Fixed: Problem caused by incorrectly set environment variables causing make to use gcc (instead of g++) to compile and link C++ code.
