Original GitHub issue: https://github.com/jmcnamara/libxlsxwriter/issues/241

Originally assigned to: @jmcnamara on GitHub.

When I issue a 'workbook_close' on linux, I get a segmentation fault when zipOpen is called:

Line 109 in packager.c:

    /* Create a zip container for the xlsx file. */
#ifdef _WIN32
    packager->zipfile = _open_zipfile_win32(packager->filename);
#else
-->    packager->zipfile = zipOpen(packager->filename, 0);
#endif

I don't understand why. I built the latest github clone, using the following commands:

mkdir buildd
cd buildd
cmake .. -DMAKE_BUILD_TYPE=Debug
cmake --build . --config Debug

Build log:

What is the return code/error when you compile and run the anatomy.c program in the examples directory?:

I tried using the system minizip, e.g. it could be using the wrong minizip functions at runtime?

hans@rhialto:~/devel/libxlsxwriter/third_party/minizip$ aptitude search minizip
p   libminizip-dev                                               - compression library - minizip development files                        
i A libminizip1                                                  - compression library - minizip library                                  
p   minizip                                                      - compression library - minizip tools

because minizip is installed as library on the system?

So I installed libminizip-dev and compiled again using -DUSE_SYSTEM_MINIZIP=On

But it didn't change the behaviour.

https://github.com/jmcnamara/libxlsxwriter/blob/master/examples/anatomy.c

works fine.

It could be some overlap. Multiple minizip's in the linked libraries (included as "third party"). I'm also using QuaZip in my project.

anatomy.c works fine.

In that case it is probably a build/link issue in your app and I'm probably not going to be able to help you much.

But if you can reproduce it with a simple program or find an issue in the CMake build let me know and I'll take a look.

Closing for now.

You can leave it closed. It was indeed a problem with multiple linked libraries that were included as 'third-party' (clash quazip / libxlsxwriter).
