[Qgis-user] QGIS installation error from own build

[Sachin Kumar]

I am building *QGIS 3.10.5* on Windows 10 Pro and Visual Studio 2015.
Everything is going right and solution build successful and installed in
OSGeo4W/apps/qgis-test folder. After that I had run perl creatensis.pl in
command prompt and it create a package with name
*“QGIS-OSGeo4W-3.10.5-1-Setup-x86_64”* with is default download, which run
successful after installation.

When I copied my build files from qgis-test folder to
“..\ms-windows\osgeo4w\unpacked-x86_64\apps\qgis” and copied
“OSGeo4W/apps/qgis-test/bin/qgis.exe” to
“..\ms-windows\osgeo4w\unpacked-x86_64\bin and rename *qgis.exe*to
*qgis-bin*”. After that run perl creatensis.pl I get
“QGIS-OSGeo4W-3.10.5-2-Setup-x86_64.exe”.

After installation I get following error:

Error loading QGIS
Oops, looks like an error loading QGIS
Details:
Could not load qgis_app.dll
Windows Error: The specified module could not be found.
Help:
Check C:\Program Files\QGIS 3.10\bin\qgis-bin.env for correct environment
paths

Earlier I also get the same error hence I format my system and install
fresh Window 10 Pro, but now again I am getting the same error. Is there
any bug during packaging? Any solution
