Я побудував бібліотеку просторітів, потім бібліотеку gdal з підтримкою просторіту. Також побудований mapserver, який успішно залежить від gdal. Проблем із зв’язком не було.
Коли я намагаюся виконати утиліту gdal, я отримую:
$ 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
Але все здається нормально:
$ ldd /usr/local/bin/ogrinfo.exe
ntdll.dll => /cygdrive/c/WINDOWS/system32/ntdll.dll (0x7c900000)
kernel32.dll => /cygdrive/c/WINDOWS/system32/kernel32.dll (0x7c800000)
cyggdal-1.dll => /usr/local/bin/cyggdal-1.dll (0x710c0000)
cygcurl-4.dll => /usr/bin/cygcurl-4.dll (0x63d80000)
cyggcc_s-1.dll => /usr/bin/cyggcc_s-1.dll (0x67f00000)

cygpng12.dll => /usr/bin/cygpng12.dll (0x6f200000)
Якщо я скопіюю cyggdal-1.dll у поточну папку:
$ ogrinfo.exe
/usr/local/bin/ogrinfo.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory
Отже, що таке "?" бібліотека?
$ ldd cyggdal-1.dll
ntdll.dll => /cygdrive/c/WINDOWS/system32/ntdll.dll (0x7c900000)
kernel32.dll => /cygdrive/c/WINDOWS/system32/kernel32.dll (0x7c800000)

Що це за "???" ? Як вирішити цю проблему?
