Hi Stefan,

When I compiled DRS4 software version 4.0.0 on Linux (Debian Squeeze) I got this compilation error:

g++ -g -O2 -Wall -Wuninitialized -fno-strict-aliasing -Iinclude -DOS_LINUX -DHAVE_LIBUSB -DUSE_DRS_MUTEX musbstd.o mxml.o strlcpy.o DRS.o ConfigDialog.o DOFrame.o DOScreen.o DRSOsc.o MeasureDialog.o Measurement.o Osci.o InfoDialog.o DisplayDialog.o AboutDialog.o EPThread.o rb.o main.o -o drsosc -lpthread -lutil -lusb -pthread   -lwx_gtk2u_richtext-2.8 -lwx_gtk2u_aui-2.8 -lwx_gtk2u_xrc-2.8 -lwx_gtk2u_qa-2.8 -lwx_gtk2u_html-2.8 -lwx_gtk2u_adv-2.8 -lwx_gtk2u_core-2.8 -lwx_baseu_xml-2.8 -lwx_baseu_net-2.8 -lwx_baseu-2.8
DOFrame.o: In function `DOFrame':
/srv/zatserkl/work/drs4/drs-4.0.0/src/DOFrame.cpp:237: undefined reference to `TriggerDialog::TriggerDialog(wxWindow*)'
/srv/zatserkl/work/drs4/drs-4.0.0/src/DOFrame.cpp:237: undefined reference to `TriggerDialog::TriggerDialog(wxWindow*)'
collect2: ld returned 1 exit status
make: *** [drsosc] Error 1

To fix it I added TriggerDialog.o into CPP_OBJ line of the Makefile:

CPP_OBJ       = DRS.o ConfigDialog.o DOFrame.o DOScreen.o DRSOsc.o MeasureDialog.o Measurement.o Osci.o InfoDialog.o DisplayDialog.o AboutDialog.o EPThread.o rb.o TriggerDialog.o

Best,

Andriy.
