Simple Browser revisited.

[Tom]

At the very least you need the packages qt5-qtbase , qt5-qtbase-gui , qt5-qtbase-common. Plus additional dependencies for libc, libcx and many more.

And of course also qt5-qtwebengine-os2 and qt5-qtwebengine-chromium-os2.

[mauro]

That new error message indicates that qtweb5c.dll cannot find the procedure LIBCX0._shmem_close .

Just guessing now: did you perhaps *only* install qt5-qtwebengine-examples and qt5-qtwebengine-debuginfo ? That is not enough!

YES, I'm sorry having understood that those two QT5 packages could install every QT5 (and libs) package-dependency needed for working. That is how I expected an rpm installation behaves.

You should install these packages (although the first one is already enough - the debuginfo is only needed when writing a support ticket) *in addition to* a normal install of qt5. At the very least you need the packages qt5-qtbase , qt5-qtbase-gui , qt5-qtbase-common.

Ok, I would go for it but.....

Plus additional dependencies for libc, libcx and many more.

....go nowhere if I don't know exactly what to do here.  Any guide or how to that I can read to get ready for running the simple browser?

And of course also qt5-qtwebengine-os2 and qt5-qtwebengine-chromium-os2

ok, after all above.
Thank you

Doesn't the error lie inside stdcpp6.dll, which is part of the package libstdc++ ? It reports a problem with the procedure "GCC1.___gthread_os2_mutex_lock" inside stdcpp6.dll.
Gcc1.dll (which is part of the package libgcc) does not look like the culprit.

It may indeed be that the problem is being caused by another version of stdcpp6.dll somewhere else on mauro's  system.

Stdcpp6 is trying to load the export ___gthread_os2_mutex_lock from libgcc and not finding it. This is usually caused by mismatched DLL versions

Was wondering it I screwed up and used netlabs-exp at some point, so a new install of ArcaOS 5.0.6.16 EN, which is actually a beta of 5.1 and includes the QT5 libs and now defaults to Pentium4.
Doing yum install qt5-qtwebengine-examples resulted in

And after marking everything to load high resulted in a working simplebrowser that is much more stable and where I am posting this from.
Not sure why mauro is getting so many sys2070's as netlabs_rel should be up to date enough. Guess I should compare to a new install of 5.0.7 later.

Consider I'm on a Warp 4.52 VirtualBox machine, if it may take difference

Sorry, I don't have that information. I had to use trial and error when a testversion became available beginning of 2021 (based on the readme.txt in that package).

One way is what Dave describes below: install the latest version of ArcaOS.
Another way is to use ANPM to install the metapackage QT5: that installs an obsolete version of QT5 (I think 5.11.x ?) and after that use ANPM to update the installed QT5-packages to their latest  versions (5.15-2) which also pulls in required versions of other packages.

After that exercise, check with a tool like pmdll or check32dll which required dlls simplebrowser.exe needs.

Quite a bit of work! Sorry I cannot be of more help.

[Dave Yeo]

Hi Mauro, the yum/rpm environment should still work on Warp 4.52, everything will need to be up to date, including the QT5 libs and make sure that your @unixroot\usr\lib is at the front of LIBPATH, even having a dot first can cause problems if something loads an old DLL.
You will have problems due to the kernel, leaking high memory for example and everything that can be (not libc, libcx, libgcc) loaded high needs to be.

Hi Igor, yea it is crashy and sometimes just vanishes. Need as much marked to load high as possible. After doing the *turbo install, which marks all the DLLs that Mozilla uses to load high, I did this to load most everything I could think of to load high,

Code: [Select]

highmem -c av*dll
highmem -c evnt*dll
highmem -c xvidcore.dll xslt1.dll xslt.dll vorbis0.dll vorbise2.dll vorbisf3.dll webp7.dll webpdec3.dll webpdem2.dll webpmux3.dll
highmem -c swresa1.dll swresa3.dll swscal3.dll swscal5.dll x264160.dll sqlite30.dll qt5*dll
highmem -c theora0.dll theorad1.dll theorae1.dll opus0.dll ogg0.dll libvpx6.dll libvpx4.dll libvpx2.dll kai1.dll hunspel0.dll
need to check if highmem.exe accepts response files, it should, then turn this into a response file.
I also killed ffturbo here as I don't use Firefox much, killing other xxturbo programs might be a good idea to free memory. And of course have the minimal running when testing.

in fact now, after having checked which dependencies those two packages have installed, I found qt5-qtbase , qt5-qtbase-gui , qt5-qtbase-common there, with other QT5 stuff.
As it should be.
No qt5-qtwebengine-os2 and qt5-qtwebengine-chromium-os2 packages available.

[Dave Yeo]

I see qt5webengine and qt5webengine-examples installed, it should be good enough as long as your LIBPATH is correct.

No qt5-qtwebengine-os2 and qt5-qtwebengine-chromium-os2 packages available.

My mistake: I meant qt5-qtwebengine and qt5-qtwebengine-chromium (without '-os2' at the end). I looked up those names on bitwisework's qt5-os2 repository at github.com, and there they have that '-os2' part at the end of their names, but apparently that is not included in the names of the rpm-packages.

I tried to install qt5-qtwebengine-examples on a laptop, and the list of packages that were to be installed or updated mentioned

dbus-libs
libc
libkai
pcre2-syntax
pcre2-utf16
qt5-qtbase
qt5-qtbase-common
qt5-qtbase-gui
qt5-qtdeclarative
qt5-qtwebchannel
qt5-qtwebengine
qt5-qtwebengine-examples

Several other packages that are needed were not mentioned because they were already installed and at their latest versions (like libxslt and minizip).

So apparently qt5-qtwebengine-chromium is not needed, although I expected that it would be needed.

[mauro]

I see qt5webengine and qt5webengine-examples installed, it should be good enough as long as your LIBPATH is correct.

I discovered LIBPATH line in config.sys a bit messed (yes: there was a dot just after the = ) and I corrected it as you wrote, with C:\USR\LIB as first call.
But no improve.
In addition, if it means something, Firefox does not run anymore, see error message image.  It can't load anymore its xul.dll , faulty module LIBVPX4

[Pete]

Hi

Firefox cannot run because you have removed it's ability to find it's dll files.
Reinstate the "." at the start of libpath eg:-
   LIBPATH=.;
Then Firefox (and other apps?) can find required dll files.

The "." in LIBPATH means an app looks in it's own/current directory for supporting dll files.


Regards

Pete
 

[Dave Yeo]

Hi Pete, Firefox can find its program DLLs without LIBPATH. All the others should be in @unixroot\usr\lib which should be close to the beginning of the LIBPATH, often @unixroot\usr\local\lib is in front and by default is empty.

Hi Mauro, sounds like you don't have libvpx-legacy-4 installed. It also sounds like you have a mess, guessing, from installing the DLL's needed by Firefox manually. Things like libvpx4.dll should not be in the Firefox program directory.
Here's a which2.exe which can list DLL's in the libpath, eg

Code: [Select]

which2 -la libvpx4.dll
Do similar for other DLL's that give you a sys2070

@Pete, I've restored the line LIBPATH=.; ......      as it was before, keeping C:\USR\LIB as first call

@Dave , in the actual system (after the qt5-qtwebengine-examples installation) :

[C:\OS2\WHICH2]which2 -la libvpx4.dll
libvpx4.dll is NOT FOUND in:
 ., c:/usr/lib, c:/usr/local/lib, c:/ibmlan/netlib, c:/muglib/d
 c:/ibmgsk50/lib, c:/ibmgsk40/lib, c:/ibmgsk/lib, c:/mptn/dll,
 c:/ibmcom/dll, c:/os2/mdos, c:/, c:/os2/apps/dll, c:/mmos2/dll
 c:/vlc2/usr/local/lib, c:/ndfs, c:/odin/system32, c:/office51

in the previous state system, the one I've cloned for working with this task:

[C:\OS2\WHICH2]which2 -la libvpx4.dll
c:/usr/lib/libvpx4.dll

and of course Firefox runs.

While for libcx0.dll , mentioned in the latest error message when trying to start simplebrowser.exe
[C:\OS2\WHICH2]which2 -la libcx0.dll
c:/usr/lib/libcx0.dll

appears to be in the right place
