[QGIS-Developer] QGIS-Server 2.99: Apache Internal Server Error

Tue Jul 25 08:01:13 PDT 2017

Hi everybody,

I have some problems to run QGIS-Server 2.99.

I'm not sure where the problems exactly come from: mod_fcgid, QGIS-Server
or my own settings?
With the LTR-Version of QGIS-Server everything works just fine, so I guess
the issues are in my environment variables or the current QGIS-Server
itself.
Hopefully someone is able to answer this question.

The Systems I tried with are (both were clean before):
1.
Debian stretch
Own QGIS-master build AND nightly apt-packages
Apache (v2.4.25) with mod_fcgid (v2.3.9)

2.
Windows 7
Latest OSGeo4W QGIS-Dev Version
Apache 2.4.18 with mod_fcgid (v2.3.7)

----DEBIAN----

When I run the qgis_mapserv.fcgi directly in the command line, everything
is fine and I get the right response back.

##Direct Request
QUERY_STRING="SERVICE=WMS&VERSION=1.3.0&MAP=/usr/lib/
cgi-bin/test.qgs&REQUEST=GetProjectSettings" QGIS_SERVER_LOG_LEVEL="1"
QGIS_SERVER_LOG_FILE="/tmp/qgis_server.log" /usr/lib/cgi-bin/qgis_mapserv.
fcgi
(Btw: Another Problem is to store the response of a GetMap-Request in
*.png-File 'QUERY_STRING="......REQUEST=GetMap" ./qgis_mapserv.fcgi >
/tmp/test.png' because the first four lines are ASCII-Informations about
QGIS Server. Maybe someone knows a solutions for that as well?)

##With Apache
When I try the same request via Apache I get an "Internal Server Error"
Request:
http://localhost/qgis_mapserv.fcgi?SERVICE=WMS&VERSION=1.3.
0&MAP=test.qgs&REQUEST=GetProjectSettings

apache-config:

apache-error.log:

The same error I get on the Windows-Machine. The only difference is, that
I'm not able to run the qgis_mapserv.fcgi.exe directly there (=>
Qt5Core.dll error)

----WINDOWS----

I spent a lot of time already in "playing around" with the
configuration-files, but without any result.

Thanks,
Benedikt
