However, the method using Makefile.msc accomplishes a few things that the do-it-all-almost CL invocation does not. For example, it compiles sqlite3.rc as a resource source and causes information such as the file version, source id, copyright, etc. to be linked into the DLL as a resource. (This can be seen in Windows file explorer by right-clicking on the DLL, clicking the “Properties” button, then clicking the “Details” tab.) With either method, it is possible to set a great many compile options. The makefile has provisions for setting them in a consistent way. And as ‘make’ aficionados know, it is a very convenient place to keep track of and reuse how you want to build something. That said, standalone CL invocation is great for just getting something made quickly when bothering with more files is just excess bother. ___ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users

Or you can input a .def file to the linker with the name of the symbols to export. Unlike "-shared" on *nix, the linker does not export entrypoints unless told to do so. The above command should yield the .dll and the .lib import library. If you also get a .manifest then you need to attach it to the .dll using the mt command thusly: mt -nologo -manifest SQLite3.dll.manifest -outputresource:SQLite3.dll;2 --- The fact that there's a Highway to Hell but only a Stairway to Heaven says a lot about anticipated traffic volume. ___ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
[sqlite] Windows dll - Export Symbol
Lloyd writes: I wish to build SQLite as a dll in Windows. As per the documentation here https://www.sqlite.org/howtocompile.html, I have executed the command cl sqlite3.c -link -dll -out:sqlite3.dll on Visual Studio x86 command prompt. It seems that the dll built doesn't export any symbols! I checked it using the dumpbin utility. But the dll downloaded from www.sqlite.org exports symbols. How can I build the dll correctly? The project publishes a file, Makefile.msc, which is written in the language understood by NMAKE.exe, (which ships with Visual Studio.) It defines a target, ‘dll’ (sans quotes), recipe for which builds the DLL you want. You could either study that file to see the relevant flags for CL.exe (and LINK.exe and a couple other tools), or you could invoke NMAKE in a command-line shell thusly: nmake -f Makefile.msc dll For the latter, you would first run the VS batch file that sets the environment so those tools can find necessary files. ___ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
[sqlite] Windows dll - Export Symbol
Hi, I wish to build SQLite as a dll in Windows. As per the documentation here https://www.sqlite.org/howtocompile.html, I have executed the command cl sqlite3.c -link -dll -out:sqlite3.dll on Visual Studio x86 command prompt. It seems that the dll built doesn't export any symbols! I checked it using the dumpbin utility. But the dll downloaded from www.sqlite.org exports symbols. How can I build the dll correctly? Thanks, Lloyd ___ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
