Construí una biblioteca espacial y luego una biblioteca gdal con soporte espacial. También se construyó el servidor de mapas que depende de gdal con éxito. No hubo ningún problema con la vinculación.
Cuando intento ejecutar una utilidad gdal me sale:
$ ogrinfo.exe
/usr/local/bin/ogrinfo.exe: error while loading shared libraries: cyggdal-1.dll: cannot open shared object file: No such file or directory
Pero todo parece estar bien:

Si copio el cyggdal-1.dll a la carpeta actual:
$ ogrinfo.exe
/usr/local/bin/ogrinfo.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory
Entonces, ¿qué es un '?' ¿biblioteca?
$ ldd cyggdal-1.dll

kernel32.dll => /cygdrive/c/WINDOWS/system32/kernel32.dll (0x7c800000)
