32-bit apps on 64-bit Fedora 28

Paul_Rodman · August 30, 2018, 4:40pm

For the life of me I cannot get 32-bit apps (compiled with Xojo 2017r1.1) to run on Fedora 28 64-bit. I tried the suggested installation on to no avail, i.e.

sudo yum install glib2.i686 libgcc.i686 libstdc++.i686 gtk3.i686 webkitgtk3.i686

(it couldn’t find webkitgtk3.i686).

Can someone give me the definitive answer (and procedure) to get this going? Alas, I have no first-born to give away, but you’ll have the thanks of several frustrated users and an ignorant developer.

Hi Paul,

If you start your app from a Terminal, what errors are displayed?

Paul_Rodman · August 30, 2018, 5:19pm

I cd to the directory containing the app binary, and type in the binary file’s name. I get

bash: xxxxx: command not found...

where xxxxx is the filename.

The permissions are 777 (i.e. executable).

I’m a total Linux ignoramus, so go gently…

Tim_Jones · August 30, 2018, 5:20pm

You have to precede the binary with either the full path, or in this case “./”, so try:

./xxxxx

Paul_Rodman · August 30, 2018, 5:39pm

bash: ./xxxxx: No such file or directory

The file is there, trust me ;^)

Paul_Rodman · August 30, 2018, 5:42pm

64-bit apps work fine. The logs don’t throw any light either.

I haven’t used Linux, but I have read several posts about ldd your-app, maybe you can execute that to see if anything is missing?

Paul_Rodman · August 30, 2018, 5:56pm

ldd xxxxx

returns

‘not a dynamic executable’

Tim_Jones · August 30, 2018, 6:02pm

We’ve made some assumptions here - is your Web app a standalone app or a CGI app?

Jason_Parsley · August 30, 2018, 6:31pm

Can you please post the results of this:

cd [full path to where your application is]
ls -al

Paul_Rodman · August 30, 2018, 7:00pm

It’s a desktop app, not a web app.

Here’s the ls -al result:

EKM Dash is the executable. (yes, I used both ‘EKM Dash’ and EKM\ Dash in my above travails to get past the embedded space).

Paul_Rodman · August 30, 2018, 7:03pm

You can download the linux version of the app I’m trying to get going here

Tim_Jones · August 30, 2018, 7:09pm

When you launch an app with spaces, you must either escape the space or place the command into quotes, so:

./EKM\ Dash
or
“./EKM Dash”
Sorry - I missed that last line.

Do this:

file ./EKM\ Dash

Paul_Rodman · August 30, 2018, 7:15pm

file ./EKM\ Dash

./EKM Dash: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.6.15, BuildID[sha1]=2547358de8b0cf1a01ab0c200f1e8ce26a853e7c, not stripped

Jason_Parsley · August 30, 2018, 7:40pm

Does removing the single quotes from the actual file name make any difference?

Tim_Jones · August 30, 2018, 7:47pm

So “ldd” reports not a dynamic executable, but “file” clearly reports “dynamically linked” - try ldd again with proper quoting.

Tim_Jones · August 30, 2018, 7:58pm

Can you rebuild it again and make the app name EKM-Dash instead of using a space?

Paul_Rodman · August 30, 2018, 8:18pm

@Tim Jones

[parallels@localhost EKM Dash]$ ldd ./EKM\\ Dash not a dynamic executable [parallels@localhost EKM Dash]$ ldd EKM\\ Dash not a dynamic executable [parallels@localhost EKM Dash]$ ldd 'EKM Dash' not a dynamic executable

I can rebuild it. Stay tuned.

@Jason Parsley
No, quotes don’t help.

Paul_Rodman · August 30, 2018, 8:22pm

OK, rebuilt with the name EKM-Dash. No change:

Jason_Parsley · August 30, 2018, 8:41pm

This seems to be a key line:

bash: ./EKM-Dash: No such file or directory

Are you compiling this on macOS? On Linux? If on macOS, how are you getting it on the Linux VM?
