I've been trying to get QT to compile using cygwin. I've checked the mailing lists and online information on porting it, and gotten pretty far, but now i'm stuck on a problem I have no idea how to fix. It seems to be trying to call a function that it can't find. I think(I'm a newbie at this) that the '_imp__' prefix to all the errors means that its is trying to access exported functions from another file. --Output from running 'make'-- make[5]: Entering directory `/usr/local/qt/tools/designer' if [ -d util ]; then cd util ; make; fi make[6]: Entering directory `/usr/local/qt/tools/designer/util' make[6]: Nothing to be done for `all'. make[6]: Leaving directory `/usr/local/qt/tools/designer/util' make[5]: Leaving directory `/usr/local/qt/tools/designer' make uic make[5]: Entering directory `/usr/local/qt/tools/designer' if [ -d uic ]; then cd uic ; make; fi make[6]: Entering directory `/usr/local/qt/tools/designer/uic' g++ -L/usr/local/qt/lib -Wl,-rpath,/usr/local/qt/lib -o /usr/local/qt/bin/uic uic.o ../shared/widgetdatabase.o ../shared/domtool.o ../integration/kdevelop/kde widgets.o -lqutil -L../lib -lqt -L/usr/X11R6/lib -I/usr/X11R6/include -l SM - lICE -lXft -L/usr/X11R6/lib -lGLU -lGL -lXmu -lXext -lX11 -lm /usr/local/qt/lib/libqt.a(qpngio.o)(.text+0x38):qpngio.cpp: undefined reference to `_imp__png_get_io_ptr' /usr/local/qt/lib/libqt.a(qpngio.o)(.text+0x70):qpngio.cpp: undefined reference to `_imp__png_error' /usr/local/qt/lib/libqt.a(qpngio.o)(.text+0xab):qpngio.cpp: undefined reference to `_imp__png_get_io_ptr' /usr/local/qt/lib/libqt.a(qpngio.o)(.text+0xdb):qpngio.cpp: undefined reference to `_imp__png_error' /usr/local/qt/lib/libqt.a(qpngio.o)(.text+0xfa):qpngio.cpp: undefined reference to `_imp__png_get_io_ptr' /usr/local/qt/lib/libqt.a(qpngio.o)(.text+0x13f):qpngio.cpp: undefined reference to `_imp__png_get_valid' /usr/local/qt/lib/libqt.a(qpngio.o)(.text+0x15c):qpngio.cpp: undefined reference to `_imp__png_get_gAMA' /usr/local/qt/lib/libqt.a(qpngio.o)(.text+0x17f):qpngio.cpp: undefined reference to `_imp__png_set_gamma' /usr/local/qt/lib/libqt.a(qpngio.o)(.text+0x1b0):qpngio.cpp: undefined reference to `_imp__png_get_IHDR' /usr/local/qt/lib/libqt.a(qpngio.o)(.text+0x451):qpngio.cpp: undefined reference to `_imp__png_set_packing' /usr/local/qt/lib/libqt.a(qpngio.o)(.text+0x466):qpngio.cpp: undefined reference to `_imp__png_read_update_info' -- ** GOES ON LIKE THIS FOR PAGES ** -- /usr/local/qt/lib/libqt.a(qpngio.o)(.text+0x2f45):qpngio.cpp: undefined referenc e to `_imp__png_get_x_pixels_per_meter' /usr/local/qt/lib/libqt.a(qpngio.o)(.text+0x2f64):qpngio.cpp: undefined referenc e to `_imp__png_get_y_pixels_per_meter' /usr/local/qt/lib/libqt.a(qpngio.o)(.text+0x2f8c):qpngio.cpp: undefined referenc e to `_imp__png_get_text' collect2: ld returned 1 exit status make[6]: *** [/usr/local/qt/bin/uic] Error 1 make[6]: Leaving directory `/usr/local/qt/tools/designer/uic' From what I can figure out the functions that it is trying to call are located in 'src/3rdparty/libpng/png.c'. Has anyone come across this problem, or know how to fix it? The header files include in qpngio.cpp, png.h has a bunch of stuff like this( which i have no idea what it does, and therefore can't fix ): /* Return the user pointer associated with the I/O functions */ extern PNG_EXPORT(png_voidp,png_get_io_ptr) PNGARG((png_structp png_ptr)); /* Fatal error in PNG image of libpng - can't continue */ extern PNG_EXPORT(void,png_error) PNGARG((png_structp png_ptr, png_const_charp error)); Thnx for the help... *wave* ~Michael Chavez, Resident Newbie -- Want to unsubscribe from this list?
