What version of libpng is required by Mapserver 6.4.1? we have a problem with a client_wms call through a newly compiled Mapserver v6.4.1 on our Unbuntu server. Here is a layer from my map file:
LAYER NAME lakes GROUP "vector" TYPE RASTER STATUS ON CONNECTION "remote/WMSServer?" CONNECTIONTYPE WMS METADATA "wms_srs" "EPSG:2193" "wms_name" "14,15" "wms_server_version" "1.1.1" "wms_format" "image/png" END END This worked fine under 6.0.1, but now fails with 6.4.1. This is the error message: <?xml version='1.0' encoding="ISO-8859-1" standalone="no" ?> <!DOCTYPE ServiceExceptionReport SYSTEM "http://schemas.opengis.net/wms/1.1.1/exception_1_1_1.dtd";> <ServiceExceptionReport version="1.1.1"> <ServiceException> msDrawMap(): WMS connection error. Failed to draw WMS layer named 'lakes'. This most likely happened because the remote WMS server returned an invalid image, and XML exception or another unexpected result in response to the GetMap request. Also check and make sure that the layer's connection URL is valid. msDrawRasterLayerLow(): Unable to access file. Corrupt, empty or missing file '/vsimem/msout/5306bf40_6ceb_0.img.tmp' for layer 'lakes'. The PNG driver failed to in png_create_read_struct(). This may be due to version compatibility problems. </ServiceException> </ServiceExceptionReport> Any clues?
