Slavek, Darrell, I am having fits with a handful of packages in 3.5.13 with the configure error: configure: error: Qt (>= Qt 3.3 and < 4.0) (library tqt-mt) not found Of course it isn't found, the file is qt-mt (/opt/qt3/lib/libqt-mt.so). The configure.log discloses the actual error: configure: 22827: /opt/qt3/include/qstyle.h taking that configure:23062: rm -rf SunWS_cache; g++ -o conftest -Wno-long-long -Wundef -ansi -D_XOPEN_SOURCE=500 -D_BSD_SOURCE -Wcast-align -Wchar-subscripts -Wall -W -Wpointer-arith -fno-builtin -g3 -fno-inline -march=i686 -mtune=generic -O2 -pipe -fstack-protector --param=ssp-buffer-size=4 -D_FORTIFY_SOURCE=2 -Wformat-security -Wmissing-format-attribute -Wno-non-virtual-dtor -fno-exceptions -fno-check-new -fno-common -I/usr/include/tqt -I/opt/qt3/include -I. -DQT_THREAD_SUPPORT -D_REENTRANT -Wl,-O1,--sort-common,--as-needed,-z,relro -L/opt/qt3/lib conftest.cpp -ltqt-mt -lpng -lz -lm -ljpeg -ldl -lXext -lX11 -lSM -lICE -lpthread 1>&5 /usr/bin/ld: cannot find -ltqt-mt The problem is that nowhere in the code that I can find is there anything that would generate -ltqt-mt instead of -lqt-mt?? Meaning -- All of the pkgconfig files are correct. The pkgconfig files at issue are: /opt/qt3/lib/pkgconfig/qt-mt.pc /usr/lib/pkgconfig/tqt.pc BOTH CORRECTLY list -lqt-mt and NOT -ltqt-mt... cat /opt/qt3/lib/pkgconfig/qt-mt.pc prefix=/opt/qt3 exec_prefix=${prefix} libdir=${prefix}/lib includedir=${prefix}/include qt_config=qt warn_on release incremental link_prl thread nocrosscompiler dlopen_opengl minimal-config small-config medium-config large-config full-config styles tools kernel widgets dialogs iconview workspace inputmethod network canvas table xml opengl sql release dll thread largefile stl system-mng system-jpeg system-png gif system-zlib nis cups bigcodecs x11sm xshape xinerama xcursor xrandr xrender xftfreetype xkb inputmethod dylib create_prl link_prl qt warn_on depend_includepath qmake_cache x11 x11inc create_libtool create_pc moc x11lib Name: Qt Description: Libqt-mt.so.3.3.8 Library Version: 3.3.8 Libs: -L${libdir} -lqt-mt -L/usr/lib/mysql -L/usr/X11R6/lib -lpq -lmysqlclient -lz -lXrender -lXrandr -lXcursor -lXinerama -lXft -lfreetype -lfontconfig -lXext -lX11 -lm -lSM -lICE -ldl -lpthread Cflags: -DQT_SHARED -DQT_NO_DEBUG -DQT_THREAD_SUPPORT -D_REENTRANT -I${includedir} cat /usr/lib/pkgconfig/tqt.pc prefix=/usr exec_prefix=${prefix} libdir=${prefix}/lib includedir=${prefix}/include/tqt tmoc_executable=/usr/bin/tmoc moc_executable=/opt/qt3/bin/moc uic_executable=/opt/qt3/bin/uic Name: TQt Description: Interface and abstraction library for Qt and Trinity Version: 3.5.13 Libs: -L${libdir} -ltqt -L/opt/qt3/lib -lqt-mt Cflags: -DQT_NO_ASCII_CAST -DQT_CLEAN_NAMESPACE -DQT_NO_STL -DQT_NO_COMPAT -DQT_NO_TRANSLATION -DQT_THREAD_SUPPORT -D_REENTRANT -I/opt/qt3/include -I${includedir} -include tqt.h So my question is "How in the heck can the build generate a config that looks for -ltqt-mt when the only thing the pkgconfig files point to is -lqt-mt?" -- David C.
