Hi, I met a error while install a native app to webOS(qemux86), my steps are the followings: 1. build & install webOS(./mcf -p 2 -b 2 qemux86), [Building webOS OSE | webOS Open Source Edition](https://www.webosose.org/docs/guides/setup/building-webos-ose/) 2. build & install NDK(./mcf -p 2 -b 2 qemux86), [Native Development Kit Setup | webOS Open Source Edition](https://www.webosose.org/docs/guides/setup/setting-up-native-development-kit/) 3. write a simple native app(just print "Hello world"), build it and package it, [Developing External Native Apps | webOS Open Source Edition](https://www.webosose.org/docs/tutorials/native-apps/developing-external-native-apps/) 4. check what arch the executable file is jaychou@jaychou-VirtualBox:~/samples/native-apps/external/com.sample.helloworld/BUILD$ cd .. jaychou@jaychou-VirtualBox:~/samples/native-apps/external/com.sample.helloworld$ ll 总用量 64 drwxrwxr-x 6 jaychou jaychou 4096 5月 17 10:23 ./ drwxrwxr-x 4 jaychou jaychou 4096 5月 11 10:48 ../ -rw-rw-r-- 1 jaychou jaychou 175 5月 11 10:58 appinfo.json drwxrwxr-x 3 jaychou jaychou 4096 5月 17 10:33 BUILD/ -rw-rw-r-- 1 jaychou jaychou 1640 5月 11 11:03 CMakeLists.txt -rw-rw-r-- 1 jaychou jaychou 8928 5月 11 11:17 com.sample.helloworld\_0.0.1\_arm.ipk -rw-rw-r-- 1 jaychou jaychou 8696 5月 17 10:23 com.sample.helloworld\_0.0.1\_x86.ipk -rw-rw-r-- 1 jaychou jaychou 2375 4月 19 10:29 icon.png drwxrwxr-x 2 jaychou jaychou 4096 5月 11 11:17 pkg\_arm/ drwxrwxr-x 2 jaychou jaychou 4096 5月 17 10:34 pkg\_x86/ -rw-rw-r-- 1 jaychou jaychou 1626 4月 19 10:29 README.md drwxrwxr-x 2 jaychou jaychou 4096 5月 11 20:42 src/ jaychou@jaychou-VirtualBox:~/samples/native-apps/external/com.sample.helloworld$ cd pkg\_x86/ jaychou@jaychou-VirtualBox:~/samples/native-apps/external/com.sample.helloworld/pkg\_x86$ ll 总用量 32 drwxrwxr-x 2 jaychou jaychou 4096 5月 17 10:34 ./ drwxrwxr-x 6 jaychou jaychou 4096 5月 17 10:23 ../ -rw-rw-r-- 1 jaychou jaychou 175 5月 11 10:58 appinfo.json -rwxrwxr-x 1 jaychou jaychou 13100 5月 17 10:34 helloworld\* -rw-rw-r-- 1 jaychou jaychou 2375 4月 19 10:29 icon.png jaychou@jaychou-VirtualBox:~/samples/native-apps/external/com.sample.helloworld/pkg\_x86$ file helloworld helloworld: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=e9ce17cdf9076f6d5ad5e08a503a0f61998af63b, with debug\_info, not stripped 5. check if it can run jaychou@jaychou-VirtualBox:~/samples/native-apps/external/com.sample.helloworld/pkg\_x86$ ./helloworld Hello world!jaychou@jaychou-VirtualBox:~/samples/native-apps/external/com.sample.helloworld/pkg\_x86$ ^C 6. package it to IPK jaychou@jaychou-VirtualBox:~/samples/native-apps/external/com.sample.helloworld/pkg\_x86$ cd .. jaychou@jaychou-VirtualBox:~/samples/native-apps/external/com.sample.helloworld$ ares-package pkg\_x86/ Create com.sample.helloworld\_0.0.1\_x86.ipk to /home/jaychou/samples/native-apps/external/com.sample.helloworld Success 7. install to webOS emualter but failed PS C:\Users\1\> ares-install.cmd E:\VirtualBox\Ubuntu\share\com.sample.helloworld\_0.0.1\_x86.ipk Installing package E:\VirtualBox\Ubuntu\share\com.sample.helloworld\_0.0.1\_x86.ipk ares-install ERR!

@initialjie , ~~This error is similar to [Failed to install a native app into webOS(emulator)](https://forum.webosose.org/t/failed-to-install-a-native-app-into-webos-emulator/1370/).~~ ~~So it also will be fixed in OSE 2.11.0 release.~~ It need more time to figure out. If we fix this error, we'll let you know in this post. Thanks! ---

Long time no see! This issue was resolved in webOS OSE build #359. You can check the resolved version in webOS OSE 2.11.0 release. 😁 (at the end of June) Thanks for reporting the issue and have a nice day!
