Execute AppImage file, get the error message "execv error: No such file or directory"

[HungerKiller]

I download the 'appimagetool-x86_64.AppImage'. And use it to make my appimage file successfully. However, when I execute 'myfile.AppImage' by typing "./myfile.AppImage", it returns:

• "execv error: No such file or directory" Anyone encounter this situation? Or anyone has some ideas? Thanks alot.

Is there an AppRun file in the AppDir? Is that file executable?

You should follow good practices and provide an MWE that has the bug, e.g., by uploading your AppImage somewhere and providing a link. Otherwise, we're just guessing wildly here.

[probonopd]

Which application are you packaging, and is the script you are using to do this available?

[probonopd]

@HungerKiller?

Closing due to inactivity. Please reopen in case you still think this is a bug.

[HungerKiller]

Thank you for your anwsers and sorry for inactivity. I have used other way to package the software. I cant upload the app recently, because it is a entreprise project, and the time is very busy for the projet. I will try with a small personal project later. Thanks alot and sry...

Here, I do a summary. ----------------The context---------------- Write code in QT5.9.1 and compile the code on mode Release. In the folder "Release", it contains all files needed by program. If double-click the executable file, the program can be launch. ----------------What I have done to produce the error---------------- Then use "appimagetool-x86_64.AppImage" to package the program: "./appimagetool-x86_64.AppImage Release/". It can produce a .appimage file, but when execute it, the error is "No such file or directory" ----------------What I have done to package the program successfully---------------- Use the tool "linuxdeployqt-continuous-x86_64.AppImage": "./linuxdeployqt-continuous-x86_64.AppImage Release/MyProgram". It can package the program successfully, but the package is not only one appimage file, it is a folder. Copy the folder to other PC, it works.

[probonopd]

I think what you are trying to do is ./linuxdeployqt-continuous-x86_64.AppImage Release/MyProgram -appimage? By the way, the linuxdeployqt project is located at https://github.com/probonopd/linuxdeployqt. Be sure to check the documentation at https://github.com/probonopd/linuxdeployqt#usage.

[HungerKiller]

Yes, exactly!

@probonopd I'm facing the same error while trying to run a previously AppImage'd app (this one for the record).

I'm following the "manual steps" described here. The output of appimagetool-x86_64.AppImage <appdir> seems successful, except for a couple of warnings:

Please consider submitting your AppImage to AppImageHub, the crowd-sourced
central directory of available AppImages, by opening a pull request
at https://github.com/AppImage/appimage.github.io

I also double-checked the absence of hard-coded paths in the binary that would prevent it from being relocateable. Running the appImage's version always yields execv error: No such file or directory.

Here is the .AppImage dir I'm currently using: giada-appimage.zip

[probonopd]

Multiple issues:

1. Not all dependencies are bundled, e.g.,

xubuntu@xubuntu:~$ /home/xubuntu/Downloads/Giada.AppDir/AppRun-x86_64
giada: error while loading shared libraries: libfltk.so.1.3: cannot open shared object file: No such file or directory

Checking for additional missing libraries yields:

xubuntu@xubuntu:~$ export LD_LIBRARY_PATH=/home/xubuntu/Downloads/Giada.AppDir/usr/lib/ ; find /home/xubuntu/Downloads/Giada.AppDir/ -type f -executable -exec ldd {} \; | grep "not found"
    libfltk.so.1.3 => not found
    librtmidi.so.4 => not found
    libjansson.so.4 => not found

These libraries, as well as their dependencies, need to be bundled as well.

It may be much easier to use https://github.com/probonopd/linuxdeployqt instead, which would do the required work automatically for you. Please check out the Travis CI example in its documentation; you should be able to copy-and-paste it almost 1:1 and go from there.

2. AppRun-x86_64 needs to be renamed to AppRun

[monocasual]

@probonopd thanks for your quick reply (and sorry for my late one)! You are right, there are still some missing dependencies. I'll also look into https://github.com/probonopd/linuxdeployqt more closely.

Hey! I'm trying to make an AppImage of a C++ executable which also uses glade XML files for GTK+ user interface. When I try to run the executable directly, it runs fine, but when I try to use AppRun it fails to locate the glade files. `(QuizTech:10130): GLib-GObject-WARNING **: invalid (NULL) pointer instance

(QuizTech:10130): GLib-GObject-CRITICAL **: g_signal_connect_data: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed

(QuizTech:10130): GLib-GObject-WARNING **: invalid (NULL) pointer instance

(QuizTech:10130): Gtk-CRITICAL **: gtk_widget_show_all: assertion 'GTK_IS_WIDGET (widget)' failed `

Also the appimage created does not execute with: execv error: No such file or directory I have use appimagetool to create it. The source code for my little project is available at github.com/shivangsgangadia/quiz_tech

Here is my appdir: QuizTech.AppDir.zip

[probonopd]

me@host:~$ strace -eopen -f /home/me/Downloads/QuizTech.AppDir/AppRun 2>&1 | grep glade
open("login.glade", O_RDONLY)           = -1 ENOENT (No such file or directory)

suggests that this is trying to load login.glade from the current working directory. This is not going to work. You need to make it load from a path relative to the main executable.

[shivangsgangadia]

I tried changing the file name from "login.glade" to a path "./login.glade" inside the source code. Still no improvement.

[probonopd]

Again, you need to make it load from a path relative to the main executable. Not relative to . (currrent working directory = where the user is in at the moment).

[shivangsgangadia]

Got it solved using getpwd(). The path must be relative to the AppRun executable. Thanks a lot!

[dvrsv]

For me the problem was somehow in AppRun the second line of code got tangled with the #!/bin/bash on the first line.

[pktiuk]

I had a similar problem, but I found solution here: https://github.com/OpenShot/openshot-qt/issues/93#issuecomment-198639916

Running chmod a+x ./activitywatch/AppRun helped.
To be honest, I think, that linuxdeploy should add these flags to this file. It would be a minor change in code but it could prevent some problems with packaging.

[probonopd]

The AppRun file permissions should be 0755. linuxdeploy just converts a working AppDir to an AppImage. Without the correct permissions you don't have a working AppDir to begin with. There are higher-level tools which set the permissions on this file; linuxdeploy is a low-level tool that most users should not be using directly.

You're right, and I've always wanted to do this. I was about to ask you to create an issue, but let's just fix this once and for all.

There are higher-level tools which set the permissions on this file; linuxdeploy is a low-level tool that most users should not be using directly.

A little convenience doesn't hurt IMO. This should be the final step of the AppRun deployment process.

[probonopd]

True ;-)

[Gold-Samiar]

I found it is permission problem on linux. fuse2 may be solve this problem but it is good idea if we set permissions before pack.
