[QGIS-Developer] QGIS FCGI Server 3.9.0 - JPEG renders but PNG empty

[Tomas Straupis]

Hello, Tom

  You could probably try the method described by Jorge in QGIS-user list:

  1. Compile QGIS with debug info.

  2. Create a script with all FcgidInitialEnv taken from apache config
converted to export's like:
  export QGIS_SERVER_LOG_FILE=/tmp/qgis-000.log

  3. Add query string variable and project file:
  export QUERY_STRING="SERVICE=WMS&VERSION=1.3.0&REQUEST=GetCapabilities"
  export QGIS_PROJECT_FILE="/var/www/wms/oracle.qgs"

  4. execute qgis_mapserv.fcgi with debug on:
  export QGIS_DEBUG=9
  export QGIS_LOG_FILE=/tmp/qgis.log
 ./qgis_mapserv.fcgi

  This gives both server logs as well as debug information in separate
files.
