-Subject: [PATCH] Fix sentinel errors for builds against musl libc
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This change fixes failing builds on systems with musl libc, where one
-can experience lots of errors similar to following one:
-
-```
-FAILED: src/libnrtype/CMakeFiles/nrtype_LIB.dir/font-lister.cpp.o
-/usr/bin/c++ ... -c ../src/libnrtype/font-lister.cpp
-../src/libnrtype/font-lister.cpp: In function ‘void font_lister_cell_data_func2(GtkCellLayout*, GtkCellRenderer*, GtkTreeModel*, GtkTreeIter*, gpointer)’:
-../src/libnrtype/font-lister.cpp:1236:64: error: missing sentinel in function call [-Werror=format=]
- 1236 |     g_object_set(G_OBJECT(cell), "markup", markup.c_str(), NULL);
-      |                                                                ^
-```
-
-Those errors are triggered by the compiler, because musl does not use
-GCC's or Clang's __null extension for NULL definition, because it seems
-non-conforming to the standard's requirements [1]. However, it is
-possible to trigger this error with -Wstrict-null-sentinel GCC flag on
-systems with glibc.
