Dear All, there is an "#if" in the "tutorials/guitest.C" that gives a hint it's possible to build a standalone application if to #define STANDALONE: //------------------------------------------- #ifdef STANDALONE TROOT root("GUI", "GUI test environement"); int main(int argc, char **argv) { TApplication theApp("App", &argc, argv); if (gROOT->IsBatch()) { fprintf(stderr, "%s: cannot run in batch mode\n", argv[0]); return 1; } guitest(); theApp.Run(); return 0; } #endif //------------------------------------------- In order to build a standalone application I've tried the following naive way: 1) (I've) installed qt-free-3.3.3 with the "./configure -qt-gif -thread"; 2) installed ROOT-4.00.08 with "./configure --enable-qt --enable-table"; 3) copied ".rootrc" given at http://root.bnl.gov/QtRoot/QtRoot.html#switch into the working directory ("$ROOTSYS/tutorials"); 4) copied Makefile and Makefile.arch from "../test" to the working dir.; and built an executable by "make guitest" (lazy guy); I've used the gcc version 2.96 20000731 (Red Hat Linux 7.2 2.96-112.7.1) I haven't got any compilation error message, but a core dump while trying to run the "./guitest": ------------- ** $Id: TGQt.cxx,v 1.2 2004/07/11 04:14:11 brun Exp $ this=0x8a4ed90 Error in <TUnixSystem::DynamicPathName>: QtGui[.so | .sl | .dl | .a] does not exist in .:/usr/local/ROOT/new/lib:/usr/local/ROOT/new/lib:./:/usr/lib/qt-3.3.3/lib *** Break *** segmentation violation Generating stack trace... 0x41593958 in <unknown> from /lib/i686/libc.so.6 0x0805c32b in guitest(void) + 0x37 from ./guitest 0x0805c3ed in main + 0x81 from ./guitest 0x41581657 in __libc_start_main at /usr/src/build/230306-i686/BUILD/glibc-2.2.4/csu/../sysdeps/generic/libc-start.c:129 from /lib/i686/libc.so.6 0x0804eb81 in TGGroupFrame::TGGroupFrame(TGWindow const *, TGString *, unsigned int, unsigned long, unsigned long, unsigned long) + 0x3d from ./guitest Aborted (core dumped) ------------- What is a correct way to build a standalone version of "guitest.C" with signals/slots? Thank you, Vassili.
