For possibly irrational reasons, nmake is a tool I’m uncomfortable with, so I tried to build proj4.dll by creating VS solution and project files. I separated the five outputs (proj.dll, geod.exe, nad2bin.exe, nad2nad.exe and cs2cs) into separate VS projects.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>Building somehow works for proj.4, meaning that the dll is successfully created, but no stub library (proj_i.lib). Hence the remaining programs (cs2cs, nad2nad etc) either complain about proj_i.lib not found, or about unresolved externals. Also, DUMPBIN on the created proj.dll shows an empty list of exported symbols.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>I have specified /IMPLIB:proj_i.lib, but this is ignored by VS, apparently connected to the fact that nothing is exported from proj.dll. From other libraries, I am used to find __declspec(dllexport) at the declaration of the exported symbols, but there is none of the like in the proj.4 source code. Is this Windows or VS specific?<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>Still the nmake utility obviously know what to export, DUMPBIN on the nmake-built proj.dll shows a well populated list. I have tried reading the .configure and makefile.vc files, but lack the skill to understand them.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>I guess I could read the output from DUPMBIN on the nmake-generated proj.dll and insert a __declspec(dllexport) in the source code declarations for all these symbols. Is this the only (non-nmake) way of getting these symbols exported from proj.4 under VS?<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>If I #defined a PROJ_DLL inside some #ifdef to mean __declspec(dllexport) if (WIN32 and VS-IDE) and nothing otherwise, would anyone be interested in updated proj_api.h and the .sln+.vcproj files?<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>Regards,<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>Sjur K :-)<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p></div></body></html>
