I was trying to compile ifeffit 1.2.5a again on top of Matt's installer based pgplot and I am having some trouble. I have fink installed and hence another pgplot. In order not to use my fink pgplot, it is necessary to use the configure options: ./configure --prefix=/Applications/Ifeffit --with-pgplot=/Applications/Ifeffit/lib --with-pgplot-link=/Applications/Ifeffit/lib/libpgplot_iff.a with this set of options the compile proceeds smoothly until it reaches the src/test directory upon which there are a lot of linking errors (shown below). Any advice Matt? cc -g -O2 -o ifftest1 ifftest1.o ../lib/libifeffit.a /Applications/Ifeffit/lib/libpgplot_iff.a -L/sw/lib/gcc/powerpc-apple-darwin7.3.0/3.4.0 -L/sw/lib/gcc/powerpc-apple-darwin7.3.0/3.4.0/../../.. -lfrtbegin -lg2c -lSystem ld: Undefined symbols: ..objc_class_name_AQTAdapter ..objc_class_name_NSAutoreleasePool ..objc_class_name_NSConstantString ..objc_class_name_NSString _AQTRoundLineCapStyle _NSLog _NSPointFromString _NSStringFromRect _NSStringFromSize _NSZeroPoint __NSConstantStringClassReference _objc_msgSend restFP saveFP _png_create_info_struct _png_create_write_struct _png_destroy_write_struct _png_init_io _png_set_IHDR _png_set_PLTE _png_set_tRNS _png_set_text _png_write_end _png_write_info _png_write_row _XAllocColor _XChangeGC _XCheckWindowEvent _XClearWindow _XCloseDisplay _XCopyArea _XCreateGC _XCreateImage _XCreateSimpleWindow _XDefineCursor _XDeleteProperty _XDisplayName _XDrawLine _XDrawPoint _XDrawRectangle _XFillArc _XFillPolygon _XFillRectangle _XFlush _XFree _XFreeColors _XFreeGC _XGetErrorText _XGetSelectionOwner _XGetVisualInfo _XGetWindowAttributes _XGetWindowProperty _XInternAtom _XLookupString _XMapRaised _XNextEvent _XOpenDisplay _XPutImage _XQueryPointer _XResizeWindow _XSelectInput _XSendEvent _XSetErrorHandler _XSetForeground _XSetWindowBackground _XStoreColors _XSync _XVisualIDFromVisual _XWarpPointer make: *** [ifftest1] Error 1
