linguini1 opened a new pull request, #3270:
URL: https://github.com/apache/nuttx-apps/pull/3270
## Summary
This commit introduces a Kconfig switch to include the cmocka binary built
from cmocka_main.c. The default behaviour is now changed so that cmocka is
built as a library only, which would be the desired behaviour for users
creating their own cmocka projects.
## Impact
Cmocka is now only built as a library, so the `cmocka` binary is no longer
included by default.
PR # to the NuttX kernel preserves the compilation of the `cmocka` binary for
the two existing defconfigs which use the cmocka application.
## Testing
Compilation of the cmocka libary without the binary using `sim:nsh` as a
basis:
```console
$ make -j
Create version.h
LN: platform/board to /home/linguini/coding/nuttx-space/apps/platform/dummy
Register: dd
Register: nsh
Register: sh
Register: gcov
Register: hello
Register: dumpstack
Register: gpio
Register: ostest
CP: /home/linguini/coding/nuttx-space/nuttx/include/nuttx/config.h
CP: /home/linguini/coding/nuttx-space/nuttx/include/nuttx/fs/hostfs.h
LD: nuttx
Pac SIM with dynamic libs..
'/usr/lib/libm.so.6' -> 'sim-pac/libs/libm.so.6'
'/usr/lib/libz.so.1' -> 'sim-pac/libs/libz.so.1'
'/usr/lib/libc.so.6' -> 'sim-pac/libs/libc.so.6'
'/usr/lib64/ld-linux-x86-64.so.2' -> 'sim-pac/libs/ld-linux-x86-64.so.2'
'/lib64/ld-linux-x86-64.so.2' -> 'sim-pac/ld-linux-x86-64.so.2'
SIM elf with dynamic libs archive in nuttx.tgz
```
Then, when disabling `CONFIG_TESTING_CMOCKA_ASLIB`, the compilation is:
```
$ make -j
Create version.h
LN: platform/board to /home/linguini/coding/nuttx-space/apps/platform/dummy
Register: cmocka
Register: hello
Register: nsh
Register: sh
Register: dd
Register: gcov
Register: gpio
Register: dumpstack
Register: ostest
CP: /home/linguini/coding/nuttx-space/nuttx/include/nuttx/config.h
LD: nuttx
Pac SIM with dynamic libs..
'/usr/lib/libm.so.6' -> 'sim-pac/libs/libm.so.6'
'/usr/lib/libz.so.1' -> 'sim-pac/libs/libz.so.1'
'/usr/lib/libc.so.6' -> 'sim-pac/libs/libc.so.6'
'/usr/lib64/ld-linux-x86-64.so.2' -> 'sim-pac/libs/ld-linux-x86-64.so.2'
'/lib64/ld-linux-x86-64.so.2' -> 'sim-pac/ld-linux-x86-64.so.2'
SIM elf with dynamic libs archive in nuttx.tgz
```
and I can run the cmocka application on sim:
```
nsh> cmocka --help
an elegant unit testing framework for C with support for mock objects
Usage: cmocka [OPTION [ARG]] ...
-?, --help show this help statement
-l, --list display only the names of testcases and testsuite,
don't execute them
-t, --test A only run cases where case function name matches A pattern
-p, --skip B don't run cases where case function name matches B pattern
-s, --suite C only run suites where PROGNAME matches C pattern
-f, --output-path use xml report instead of standard output
-d, --shuffle-seed shuffling test sequence,between 0 and 99999,
when seed is 0,use time(NULL) as the seed for
the random number generator
Example: cmocka --suite mm|sched --test Test* --skip TestNuttxMm0[123]
nsh>
```
