Разработка на Linux Mint 20.2 с подключенным USB Samsung GT-P3113. Android-студия(Artic Fox 2020.3.1) установлена, но вы хотите запустить Ndk-сборку (/home/george/Android/Sdk/ndk/23.0.7599858/ndk-сборка) из командной строки терминала GNOME. Я могу успешно (создавать/устанавливать/запускать) учебные пособия _1, _2 и _3, если я изменю $(GSTREAMER_NDK_BUILD_PATH)/gstreamer-1.0.mk:

 from:
GSTREAMER_LD                  := -fuse-ld=gold$(EXE_SUFFIX) -Wl,-soname,lib$(GSTREAMER_ANDROID_MODULE_NAME).so
to:
GSTREAMER_LD                  := -fuse-ld=$(EXE_SUFFIX) -Wl,-soname,lib$(GSTREAMER_ANDROID_MODULE_NAME).so
 

Однако tutorial_4 и tutorial_5 создают ошибку ld:

 GStreamer      : [GEN] => gst-build-armeabi-v7a/gstreamer_android.c
GStreamer      : [COMPILE] => gst-build-armeabi-v7a/gstreamer_android.c

ld: error: unable to find library -lgcc

Я пробовал версии gstreamer-1.0-android-universal-1.16.3, 1.18.4 и 1.18.5 с тем же результатом. Ошибка возникает при использовании плагина $(GSTREAMER_PLUGINS_NET). Чтобы сузить проблему, я заменил GSTREAMER_PLUGINS_NET на GSTREAMER_PLUGINS_NET_RESTRICTED.

Это было успешно (компиляция,ссылка,установка), но вызвало ожидаемую ошибку во время выполнения:

Ошибка, полученная от элемента urldecodebin0:для «https» не реализован обработчик URI

Где находится библиотека «gcc» в загруженном gstreamer-1.0-android-universal-1.18.X? Нужно ли его компилировать? Как мне действовать дальше?
