With all features enabled, the library size can be less than 350KiB, depending on the target platform and compiler optimization settings. Think of SQLite not as a replacement for Oracle but as a replacement for fopen() These features make SQLite a popular choice as an Application File Format. The database file format is cross-platform - you can freely copy a database between 32-bit and 64-bit systems or between big-endian and little-endian architectures. A complete SQL database with multiple tables, indices, triggers, and views, is contained in a single disk file. SQLite reads and writes directly to ordinary disk files. Unlike most other SQL databases, SQLite does not have a separate server process. SQLite is an embedded SQL database engine. SQLite is currently found in more applications than we can count, including several high-profile projects. SQLITE DOWNLOAD FOR WINDOWS 10 64 BIT CODEThe code for SQLite is in the public domain and is thus free for use for any purpose, commercial or private. If all of that fails, or if you just want to verify against a supposedly correctly compiled setup, try precompiled 64-bit binaries here or from here.SQLite is a in-process library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. Installation is as simple as finding the right ZIP, unpacking it, and setting the path. Make sure you have the x86_64/amd64 version of the Mingw toolchain. If that doesn't work, you may have the wrong compiler altogether. You can also try adding the -m64 option to the gcc commandline, that should force gcc to target the amd64 target. Do you have any way to check that? On Linux you can run the "file" command. SQLITE DOWNLOAD FOR WINDOWS 10 64 BIT 64 BITI would also make 100% sure that the built DLL is actually a 64 bit DLL and not a 32 bit DLL. The -Wl argument to gcc is what tells gcc to pass on the further arguments -out-implib,libexample_dll.a to the linker. SQLITE DOWNLOAD FOR WINDOWS 10 64 BIT HOW TO(Further down, there is an example on how to export all global functions to the DLL, like usually happens in Unix.) The page also explains that functions you want your DLL to export, must be declared with _declspec(dllexport). Gcc -shared -o example_dll.dll example_dll.o -Wl,-out-implib,libexample_dll.a Quoted from Mingw site: (Sort of, I replaced g++ with gcc) gcc -c -DBUILDING_EXAMPLE_DLL example_dll.cpp You need to pass special linker options to gcc to make it create DLLs. Calling it a DLL won't magically make it a DLL. shell.c sqlite3.c -o sqlite3_x86.dll -Wl,-out-implib,sqlite3_x86.a shell.c sqlite3.c -o sqlite3_圆4.dll -Wl,-out-implib,sqlite3_圆4.aģ2-bit: gcc -shared -DWIN32 -D_WINDOWS -D_USRDLL -DNO_TCL -D_CRT_SECURE_NO_DEPRECATE -DTHREADSAFE=1 -DTEMP_STORE=1 -DSQLITE_MAX_EXPR_DEPTH=0 -m32 -I. Adding the flag -m64 sets the compiler into 64-bit mode.Ħ4-bit: gcc -shared -DWIN64 -DNDEBUG -D_WINDOWS -D_USRDLL -DNO_TCL -D_CRT_SECURE_NO_DEPRECATE -DTHREADSAFE=1 -DTEMP_STORE=1 -DSQLITE_MAX_EXPR_DEPTH=0 -m64 -I. Getting a 64-bit version then allowed me to make SQLite for 64-bit. Turns out my MinGW build was 32-bit only. Resulted in a 740KB DLL file which still gives a BadImageFormatException. shell.c sqlite3.c -o sqlite_圆4.dll -Wl,-out-implib,sqlite3.a Used the following command instead: gcc -shared -DWIN64 -DNDEBUG -D_WINDOWS -D_USRDLL -DNO_TCL -D_CRT_SECURE_NO_DEPRECATE -DTHREADSAFE=1 -DTEMP_STORE=1 -DSQLITE_MAX_EXPR_DEPTH=0 -I. Once again, I got a 733KB DLL file (that's odd?) and once again, I got a BadImageFormatException. I also then tried doing an x86 compilation using the same method. Nice! Did it actually work? Did it nuts - I got a BadImageFormatException. I then compiled the source with the following command: gcc sqlitew64.h sqlite3.h sqlite3ext.h shell.c sqlite3.c -o sqlite_圆4.dll I eventually took an educated guess, made a new file (for neatness) called sqlite3w64.h and pasted in the following: #define WIN64 NDEBUG Here are the compiler pre-processor defines I use for a 32-bit release build: Here are the compiler pre-processor defines I use for a 64-bit release build: But apparently that will never work for Windows binaries.)Īnyway, I've been told I need the following preprocessor defines: (I first started using the autoconf amalgamation and used the configure & make tool on Linux. I'm fairly new to this sort of compilation and my efforts so far have resulted in failure. I have MinGW and I wish to compile the SQLite amalgamation source into a 64-bit dll.
