I use sc-im-0.8.2 but the same issue happens also if I clone the source from github. I'm on gentoo. I use this: https://gitweb.gentoo.org/repo/proj/guru.git/tree/dev-libs/libxlsxwriter/libxlsxwriter-1.1.4.ebuild?h=dev&id=fd50b5c39e810314d0fcb852064b52cbe684a1ad to install libxlsxwriter.

Please check you have libzip installed. It shows undefined reference to all of its functions..

I have libzip 1.8.0 installed.

*  dev-libs/libzip
      Latest version available: 1.8.0-r1
      Latest version installed: 1.8.0-r1
      Size of files: 743 KiB
      Homepage:      https://nih.at/libzip/
      Description:   Library for manipulating zip archives
      License:       BSD

with these use flags:

 * Found these USE flags for dev-libs/libzip-1.8.0-r1:
 U I
 + + bzip2       : Use the bzlib compression library
 - - gnutls      : Prefer net-libs/gnutls as SSL/TLS provider (ineffective with USE=-ssl)
 - - lzma        : Support for LZMA (de)compression algorithm
 - - mbedtls     : Use net-libs/mbedtls as TLS provider
 + + ssl         : Add support for SSL/TLS connections (Secure Socket Layer / Transport Layer Security)
 - - static-libs : Build static versions of dynamic libraries as well
 - - test        : Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
 - - tools       : Install binary tools to compare, modify and merge zip files 
 - - zstd        : Enable support for ZSTD compression

Although one interesting thing is that I get no cflags for libzip with pkg-config:

$ pkg-config --cflags libzip

$

And no flags for libxlsxwriter either:

$ pkg-config --cflags xlsxwriter

$

and the libs for both give me the output:

$ pkg-config --libs xlsxwriter
-L/usr/lib -lxlsxwriter -lz 
$ pkg-config --libs libzip
-lzip

Another thing that may interest you is that I can't fine any .so files for libxlsxwriter. All I have is

.rw-r--r-- 660k root  7 May 08:09  /usr/lib64/libxlsxwriter.a

After my comment it dawned on me that I wasn't building libxlsxwriter with dynamic libraries. Adding -DBUILD_SHARED_LIBS="ON" to cmake args fixed the issue.
