Unable to load proj4 in MapInfo for transformation coordinates

  • 1.  Unable to load proj4 in MapInfo for transformation coordinates

    Posted 14 days ago
    For the past period We used MapInfo 8.5, now we upgrade it to v17.1.0. In old version of MapInfo we used proj4 (PROJ - PROJ.4 5.2.0 documentation) opensource program to transform coordinate from Gauss to WGS84 and reverse, but the same project issue doesn't work on new version of MapInfo softver.
    I recompile new version the opensource proj4 in x86, using VS17, but I still have a problem to load in MapInfo v17.1.0, in this case MapInfo expected x32 library but when I put x32 library I have the same error.
    Also I download OseGeo package x64 where is new x86 proj.dll but in that case when I call this project MapInfo stop responding.
    Help me If you can to solve this problem.

    MIPro  17.x is 64 bit architecture.  I would believe you need to build proj4 as 64 bit to make this work.
