Wt Compile Help

Added by Michael De Paola almost 10 years ago

I wrote a Wt application based on the charts example and everything works as it should and it runs well when I compile using make -C examples/charts from the build directory. I now want to make my code portable with its own makefile so I can check it in to a repository, and then check it out anywhere and build it.

So I made a makefile, and got the application to compile, but when I run this application (even if I move the binary to where the original charts.wt builds to in wt/build/examples/charts) it gets a segmentation fault before even reaching the first line of code (which I made a print to cerr statement to check). Also, I get build warnings that I don't get when building from the original directory.

Any insight would be appreciated. and I've put my makefile and the compile output below

Below is my makefile:

#Wt Charts application makefile

#usage: make clean
#       make all
#       make install

I would try to compile in the debug mode first and get the stack trace from the crash.

RE: Wt Compile Help - Added by Michael De Paola almost 10 years ago

I removed the -O2 from the makefile and put in -ggdb instead, but when I run the stack trace all I get is

Starting program: /home/user1/share/Software/SIL UI Client/chartsdimbuild/chartsdim.wt --docroot . --http-address 0.0.0.0 --http-port 8080

which doesn't help much

RE: Wt Compile Help - Added by Michael De Paola almost 10 years ago

To make things easier and do it one step at a time I've simplified my makefile to the below:

CXX = g++
CXXFLAGS = -Wall -g -std=c++11 -I/home/user1/Downloads/git_wt/build -I/home/user1/Downloads/git_wt/src -isystem /usr/include/qt4 -isystem /usr/include/qt4/QtGui -isystem /usr/include/qt4/QtCore
CXX_DEFINES = -DBOOST_SPIRIT_THREADSAFE -DQT_CORE_LIB -DQT_GUI_LIB -DQT_NO_DEBUG -DWT_DEPRECATED_3_0_0 -DWT_WITH_OLD_INTERNALPATH_API -D_REENTRANT
LIBS = -I/usr/local/include -L/usr/local/lib -L/usr/lib/ -lwthttp -lwt -lboost_regex -lboost_signals -lboost_system -lboost_thread -lboost_program_options -lboost_date_time -L../../RealTimePlatform/SilTcpClient/ -lsiltcpclient
LDFLAGS = -Wl,-rpath=$ORIGIN/../../RealTimePlatform/SilTcpClient/:/home/user1/Downloads/git_wt/build/src/http:/home/user1/Downloads/git_wt/build/src

chartsdim.wt: ChartConfig.o ChartsExample.o CsvUtil.o PanelList.o
    $(CXX) $(CXXFLAGS) $(CXX_DEFINES) $(LDFLAGS) src/ChartsApplication.cpp ChartConfig.o ChartsExample.o CsvUtil.o PanelList.o $(LIBS) -o chartsdim.wt 

ChartConfig.o: src/ChartConfig.cpp src/PanelList.cpp include/PanelList.h include/ChartConfig.h
    $(CXX) $(CXXFLAGS) -c src/ChartConfig.cpp 

ChartsExample.o: src/ChartsExample.cpp src/ChartConfig.cpp src/CsvUtil.cpp include/ChartsExample.h include/ChartConfig.h include/CsvUtil.h
    $(CXX) $(CXXFLAGS) -c src/ChartsExample.cpp

CsvUtil.o: src/CsvUtil.cpp include/CsvUtil.h
    $(CXX) $(CXXFLAGS) -c src/CsvUtil.cpp

PanelList.o: src/PanelList.cpp include/PanelList.h
    $(CXX) $(CXXFLAGS) -c src/PanelList.cpp

clean:
    rm -f *.o
    rm -f chartsdim.wt

and it doesn't crash on execution anymore though there's another issue somewhere else but I think I can find this one on my own.

Thanks for the help!

RE: Wt Compile Help - Added by Michael De Paola almost 10 years ago

My last issue was just due to a hardcoded array that I've been meaning to change to be dynamically allocated since a while back so my only issue that I'm unsure about was due to my original makefile. I copied that from a template and modified it so I'm not sure what I did wrong there, but the one I made from scratch had the program runnning as expected while that modified one causes a segfault immediately on execution before reaching main though I think I'll leave that mystery unsolved.

RE: Wt Compile Help - Added by Trigve Siver almost 10 years ago

I would recommend to get the symbols/(dev version of the libs/so) to be able to use stack trace in the future.

I haven't study your makefile but maybe you're mixing static/dynamic libraries and it is crashing somewhere in init code?
