When building the libapparmor package with musl the following error
would appear:
```
test_multi.c: In function 'main':
test_multi.c:27:30: error: implicit declaration of function 'basename' [-Wimplicit-function-declaration]
27 | printf("File: %s\n", basename(argv[1]));
| ^~~~~~~~
test_multi.c:27:24: warning: format '%s' expects argument of type 'char *', but argument 2 has type 'int' [-Wformat=]
27 | printf("File: %s\n", basename(argv[1]));
| ~^ ~~~~~~~~~~~~~~~~~
| | |
| | int
| char *
| %d
make[3]: *** [Makefile:466: test_multi_multi-test_multi.o] Error 1
```
This error can be reproduced with the following:
```
cat >.config <<EOF
BR2_aarch64=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_AARCH64_MUSL_BLEEDING_EDGE=y
BR2_PACKAGE_LIBAPPARMOR=y
EOF
make olddefconfig
make libapparmor
```
On musl libc the function `basename` is provided by included libgen.h.
This error has been addressed upstream in [1] by re-defining the
function `basename`.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
