MSG compile problem

[rroman]

When I try to compile gdal-1.5.0 on fedora core 5 with msg format support the following problem occur.

On the internet I found that it was previously discussed but did not find the solution. Any help would be apprececiated. Thanks Raymond

Bas,

Any thoughts? Mateusz, could you try and fix this up based on what Bas suggests unless Bas takes care of it?

[retsios]

The "previous discussion" mentioned was "[Bug 889] Patch to get msg format to build under Linux".

The solution was a so-called forward declaration of MSGDataset (simply adding "class MSGDataset;" at line 44).

Please try this. Unfortunately I do not have a linux machine to try it, so feel free to change anything else required to make it compile, and to "commit" the result.

Note that for the MSG driver you need to 1) enable the driver in GDAL, 2) download the (free) wavelet transform library from eumetsat (see ​http://www.gdal.org/frmt_msg.html, but it could be that eumetsat has moved the file).

Frank,

It seems that I'm not able to reproduce this problem because I'm unable to build and test the MSG driver mentioned. The problem is that EUMETSAT has changed their licensing policy and now the ​Wavelet Transform Software is licensed software available after registration and formal acceptance by EUMETSAT (see Apply for online licence link). I've submitted the form more than 3 weeks ago and got no response so far.

I'm not sure what to do now.

[Mateusz Łoskot]

I forgot to add that I've updated the ​frmt_msg.html with fresh links and notes on the Wavelet Transform Software.

Docs update (r14854)

Lichun / Bas,

Any thoughts on this?

[Mateusz Łoskot]

Folks,

Just for records, as Bas suggested, eumetsat.int is not Firefox friendly but requires IE. So, ​Apply for online licence form works only with IE. Anyone who will be submitting it should check that she gets 3 steps: 1) fill form, 2) confirm data input is valid and click ACCEPT button 3) see page with final confirmation the form has been submitted. I've reported that problem to EUMETSAT, hopefully they will fix it.

[Mateusz Łoskot]

Added MSG driver support to configure.in (r15062). EUMETSAT Wavelet Trasform software is only detected on request, option --with-msg specified.

[Mateusz Łoskot]

Fix for compilation problems and a bunch of improvements submitted to trunk (r15064).

MSG docs updated (r15065)

Also, I've started MSG Wiki page dedicated to building and using MSG driver. Feel free to document your experiences.

Successfully tested building MSG driver with GCC 4.1.2 on Linux Ubuntu 7.04

[Mateusz Łoskot]

Patch for EUMETSAT Wavelet Transform Software (version 2.03) that enables compilation with GCC 4.1.x . Original version of WT software does not compiler out of the box.

[Mateusz Łoskot]

Patch for EUMETSAT Wavelet Transform Software (version 2.03) that enables compilation with GCC 4.3.x . Original version of WT software does not compile with this compiler.

[Mateusz Łoskot]

Updated MSG driver for GCC 4.3.1 (r15066) This submission is related to attached patch for the EUMETSAT WT Software (eumetsat-wt203-gcc431-mloskot.patch). So, anyone who needs MSG driver build with GCC 4.3.1 need to do this:

• apply the patch to EUMETSAT WT Software (frmts/msg/PublicDecompWT)
• use GDAL from SVN trunk, at least revision 15066
• call ./configure with --with-msg option
• call make
