Hi, sorry if this is a silly question, I have been looking around the mailing list and in google and can't find the answer. I am trying to build poppler to be able to display pdf files in a small bibliography application I have been writing. My application is written with Qt4, and use the mingw/msys toolchain to compile. When I run ./configure all seems to work fine, as the Makefiles get generated. I can then build poppler with just a small tweak: I need to remove the -ansi option from the compile line, otherwise strdup is not visible to the compiler (I think this is a bug in mingw), and also need to copy libstdc++.dll.a to libstdc++.dll.la (again, this seems to be related to the way libtool works in mingw). With those minor glitches all builds and the tests seem to work fine. The problem I have now is that configure can't find my installation of QT. I run configure as: ./configure --enable-poppler-qt4 POPPLER_QT4_CXXFLAGS=-I/c/Qt/4.6.2/include POPPLER_QT4_CXXFLAGS=-L/c/Qt/4.6.2/lib When it gets to detecting qt4 I get the following error: configure:20472: checking for POPPLER_QT4 configure:20541: error: in `/c/Users/crega/workspace/poppler-0.14.2': configure:20552: error: The pkg-config script could not be found or is too old.  Make sure it is in your PATH or set the PKG_CONFIG environment variable to the full path to pkg-config. Alternatively, you may set the environment variables POPPLER_QT4_CFLAGS and POPPLER_QT4_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. To get pkg-config, see <<a href="http://pkg-config.freedesktop.org/">http://pkg-config.freedesktop.org/</a>>. See `config.log' for more details. I have set the env variables in the call to configure, and checking in config.log the variables are set, the Qt installation is working, because I build my app with it, so I am at a loss how to build the Qt4 wrapper. I would appreciate any pointers as to what I should try next.
