FirmwareUpgradeLog: PX4 releases github download failed "Error during download. Error: 99"

Same problem with firmware and parameter download. OS: ArchLinux.

DonLakeFlyer commented 6 years ago

As far as I know these are expected to already be on the OS. Works fine on Ubuntu 16.04. From the errors it's not that they aren't there. They are just imcompatible with Qt.

patrickelectric commented 6 years ago

This guy https://github.com/bluerobotics/ardusub/issues/147#issuecomment-382294275 have the same problem with debian. In my system I can see that I have /usb/lib/libcrypto.so.1, that's the weird thing. Running QGC with strace do not result in anything related to sll or crypto also. Besides that, adding libcrypto is not a solution, AppImageKit Desktop-Linux-Platform-Issues.

patrickelectric commented 6 years ago

From here.

    // Try to find the libssl library on the system.
    //
    // Up until Qt 4.3, this only searched for the "ssl" library at version -1, that
    // is, libssl.so on most Unix systems.  However, the .so file isn't present in
    // user installations because it's considered a development file.
    //
    // The right thing to do is to load the library at the major version we know how
    // to work with: the SHLIB_VERSION_NUMBER version (macro defined in opensslv.h)
    //
    // However, OpenSSL is a well-known case of binary-compatibility breakage. To
    // avoid such problems, many system integrators and Linux distributions change
    // the soname of the binary, letting the full version number be the soname. So
    // we'll find libssl.so.0.9.7, libssl.so.0.9.8, etc. in the system. For that
    // reason, we will search a few common paths (see findAllLibSsl() above) in hopes
    // we find one that works.
    //
    // It is important, however, to try the canonical name and the unversioned name
    // without going through the loop. By not specifying a path, we let the system
    // dlopen(3) function determine it for us. This will include any DT_RUNPATH or
    // DT_RPATH tags on our library header as well as other system-specific search
    // paths. See the man page for dlopen(3) on your system for more information.
patrickelectric commented 6 years ago

@DonLakeFlyer The problem appears to be with openssl 1.1 that does not have binary compatibility with 1.0; It appears that Qt5.10 does not have this problem. https://github.com/probonopd/linuxdeployqt/issues/209

patrickelectric commented 6 years ago

I created a AppImage with 5.10.1 with linuxdeployqt of QGC, it appears to be solved the problem, I'll do more tests with it.

DonLakeFlyer commented 6 years ago

The AppImage we drop is only tested/supported on Ubuntu. Up until now that has mostly worked on other Linux distros as well. Can we update docs to specify an install of libopenssl 1.0 prior to using QGC on those distros?

patrickelectric commented 6 years ago

What we can do is to alarm the user about this issue with new versions of libopenssl, and ask to export LD_LIBRARY_PATH=openssl-1.0_path_in_your_system. In ArchLinux, the OS have both versions available in the default package manager repository.

DonLakeFlyer commented 6 years ago

I wonder if we just move latest master to 5.10 instead of trying to deal with this some other way.

patrickelectric commented 6 years ago

I'm using it with 5.10 without problems.

jaxxzer commented 6 years ago

I'll add for encouragement that when we get past 5.9.4, we will have the debug symbols for Qt.

DonLakeFlyer commented 6 years ago

Wow, really? That's a big deal.

jaxxzer commented 6 years ago

As far as I understand: https://bugreports.qt.io/browse/QTBUG-3934

DonLakeFlyer commented 6 years ago

Now on 5.11

@patrickelectric replicated the issue.

@DonLakeFlyer Can we re-open this?

DonLakeFlyer commented 5 years ago

Some Linux folks are going to have to figure out how to fix this without breaking Ubuntu which is working fine. I don't really know anything about AppImage or how it works. I'm not sure the answer is to include the libs in the AppImage.

@thomasgubler I seem to remember from long, long, long ago that maybe you were an archlinux user. Any ideas?

patrickelectric commented 5 years ago

@Williangalvani can you confirm if https://github.com/mavlink/qgroundcontrol/issues/6337#issuecomment-385387313 works ? Should we include openssl-1.0 ?

Williangalvani commented 5 years ago

@Williangalvani can you confirm if #6337 (comment) works ? Should we include openssl-1.0 ?

Yes, it works fine with export LD_LIBRARY_PATH=/usr/lib/openssl-1.0

kikislater commented 5 years ago

Even with building from AUR repository with 3.4.4, it fails with libssl 1.1 at this time. Was previously working !

kikislater commented 5 years ago

@Williangalvani : export works fine on archlinux. Thank you for it

DonLakeFlyer commented 5 years ago

@patrickelectric This would seem to be a Qt bug wouldn't it?

patrickelectric commented 5 years ago

@patrickelectric This would seem to be a Qt bug wouldn't it?

this is related to the openssl library, when you compile and configure Qt, there is a "-DOPENSSL_API_COMPAT" parameter to select the compatibility with different versions

akontsevich commented 4 years ago

Is there any working solution for this? Some URL to see the example? As I still get the error if build Qt and QGC in CentOS 7. I'm building AppImage with appimagetool-x86_64.AppImage - replaced ancient AppImageAssistant still used in QGC here: https://github.com/mavlink/qgroundcontrol/blob/master/deploy/create_linux_appimage.sh. Whether linuxdeployqt solves this problem? Thanks!
