<div dir="ltr">If any of you can share any pointers on how to even get it to compile I'd appreciate it. I just need to access a esri file geodatabase that has curves and see if I can get them into postgis. If I have to have a separate build of gdal just for that I don't care.

<p style="margin-top:0px;margin-bottom:0px;margin-left:0px;margin-right:0px;text-indent:0px">In fact, libFileGDBAPI.so doesn't seem to embed all public proj.4 symbols. The functions are missing. But 5 or 6 global array structures, like the list of datums (pj_datums) are exposed in the data read-only section. The issue is that pj_datums doesn't seem to have the same structure: 2 columns per record in the ESRI version whereas official proj.4 expects 4 columns</p>
