Deployment problem on MAC OSX with macdeployqt Qt5.4.2 (and 5.3.2)

stephane78

the package crashes on another Mac but I have not this other Mac here today and I cannot see the command line information.I think there are libraries of /usr/lib like libc++ or others or OpenGl that are not installed on this another mac.
Can I add libraries (of /usr/lib or other) to the bundle ?

SGaist

What exact libraries are missing ?

stephane78

@SGaist, Hi , I don't know if it comes from a missing library and I am not sure because the error message is :
QSqlError("-1", "Error opening database", "out of memory")

failed to connect.

Abort trap: 6
we use sqlite in the software and the plugin is in the bundle.
I have freed memory and even with 4Gb free memory I have this message
this is not a development Mac, and it is with MacOS 10.11.3 and 8 GB memory
I have copied the software on the desktop and I run it in command line.
On two other (developments) Mac the software is ok.

SGaist

AFAIK, that's unrelated.

Where are your trying to open your database ?
Do you check that the open operation is successful before calling a query on it ?

stephane78

Hi, @SGaist , I must add a new QMessageBox in the case it doesn't find the sqlite driver.
I think this case comes when it creates the log database and if it doesn't find the sqlite driver and then cannot open the database or when it opens the log database (if the file already exists and is corrupted).

stephane78

@SGaist ,I have added a QMessageBox, if it doesn't find the sqldriver plugin and I have done an otool -L on the sqlite plugin and I have seen that it is linked with the libc++1.dylib and libSystemB.dylib.
is it possible that this two libraries are not on the Mac (10.11.3) or are not compatible with those of my development Mac (10.10.4) ?

stephane78

@SGaist, HI, I have the same problem on a VM with an older MacOS(10.9),so I have the problem on 2 MacOSes where Qt was not installed before...so I think it needs a library or there is a problem with the bundle.

stephane78

@SGaist, I have added Libraries = Frameworks to the qt.conf and I will test it on the VM

stephane78

@SGaist, Hi it does nothing.
I have now added libsqlite3.dylib to the bundle and it is not ok .
but my bundle contains other qt sql plugins and perhaps should I remove them (mysql,postgres,odbc) of the bundle ?
I have tested without the other plugins in the bundle and I have still this error....

stephane78

the software runs on two developments MacOs (with Qt and Xcode) and crashes on two other MacOS without Qt and Xcode.....

@SGaist, Hi, When I use macdeployqt (Qt5.6.0) I have this errors and warning :

WARNING: Plugin "libqsqlodbc.dylib" uses private API and is not Mac App store compliant.
WARNING: Plugin "libqsqlpsql.dylib" uses private API and is not Mac App store compliant.
ERROR: no file at "/opt/local/lib/mysql55/mysql/libmysqlclient.18.dylib"
ERROR: no file at "/usr/local/lib/libpq.5.dylib"

but I use only the sqlite plugin

SGaist

Just remove the plugins you won't use.

Where did you put the SQLite library ?

stephane78

Should I remove the other plugins from the bundle?
I have tried too with the libsqlite3.dylib in the bundle (in frameworks) but it did'nt solve the problem, I don't know if I should put it in the bundle.

stephane78

I have tested without the other sql plugins and I have the same error...

stephane78

The two MacOS on which that doesn't run are MacOS 10.9 and Mac OS 10.11.3 without Qt.
But the software and bundle was made on a Mac OS 10.10.4.
does the problem come from the MacOs version ?

SGaist

No it should not.

Things I'd do now:

Delete the bundle
Do a full re-build
Run macdeployqt on it
Delete unused plugins
Run otool -L on the remaining plugins
Check whether there's any path to a non-system library that looks fishy
Run otool -L on the application executable
Check whether there's any path to a non-system library that looks fishy

stephane78

already done several times the first three levels.
an otool -L on the sqlite plugin gives paths to Qt libraries with "@rpath" but I suppose it 's ok.

stephane78

and the sqlite plugin is linked with /usr/lib/libcc++.1.dylib and /usr/lib/libSystem.B.dylib too (and QtCore and QtSql)

stephane78

I have build with Qt5.5.1 and I have the same problem than with Qt5.6.0

stephane78

We will try later with a VM with MacOS 10.10 to see if it is a version problem
