#47 Segmentation fault

[Anonymous]

Hello,
I got segmentation fault for this code:

#include <iostream>
#define PACKAGE_VERSION "2.3.4"

#include "xlslib.h"

using namespace std;
using namespace xlslib_core;

int main (int argc, char * const argv[]) {
workbook wb;
worksheet* sh = wb.sheet("Тексты");
worksheet* sh2 = wb.sheet("Контактная информация");

int err = wb.Dump("testCPP.xls");
return 0;
}

Can you please help me.

This is documented somewhere. you MUST create at least one cell in each sheet. This is a bug in xlslib, but a very difficult bug to find! I have personally fixed it once several years ago but it keeps popping up!

Thanks for reply but this code also throws this fault:

#include <iostream>
#define PACKAGE_VERSION "2.3.4"
#include "xlslib.h"

using namespace std;
using namespace xlslib_core;

int main (int argc, char * const argv[]) {
workbook wb;
worksheet* sh = wb.sheet("Sheet 1");
worksheet* sh2 = wb.sheet("Sheet 2");
worksheet* sh3 = wb.sheet("Sheet 3");
// Title
sh->blank(0, 0);
sh->label(0,1,"test");

sh2->blank(0, 0);
sh2->label(0, 1, "test1");

sh3->blank(0, 0);
sh3->label(0, 1, "test2");

int err = wb.Dump("testCPP.xls");
return 0;
}

Your latest code looks fine. I really don't have any clue what the problem might be. Ah, the joy of open source that needs to run on huge numbers of software platforms.

All I can say is that hundreds of people are using this library and its quite stable now.

Did the test programs build? You did run ,/configure right? So, assuming you did:

./configure
make

did you try
make check

did it pass?

If that crashed, then try to bootstrap config:

./bootstrap
./configure
make
make check

Is the directory you are trying to dump the file to writeable? You might try: wb.Dump("/tmp/testCPP.xls");

If all else fails,I believe you are going to need to run this program with a debugger like gdb to find out where and why its crashing.

I'm quite newby in this area. Maybe it is my fault. I'll investigate. Thanks!

It was my fault.
