[sqlite] [SQLite]Basic query
Hi, I'm about to use sqlite-amalgamation(sqlite3.c) on Visual C++. But although the compiling was successfully finished, even if I set break point on the source code, I can't trace the working line in sqlite3.c correctly. I suspected that the sqlite3.c was optimized, but there is no opiton like that. Always the active line doesn't match to source code in debug mode. Is the code optimized automatically? if so, how can I deactivate it? If anyone knows above phenomenon, then could you please answer me?? Thanks, ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users

How exactly are you using SQLite in your program? If you are not using the SQLite C API (sqlite3_* functions) directly, it is likely that there is a second copy of the SQLite library inside that other database driver.

Re: [sqlite] [SQLite]Basic query
Hi Shinichiro, which Version of VC++ do you use? As far as I know, older versions do not support debugging source files with more than 65535 lines. Also, why do you want to debug into the sqlite.c file? The file sqlite.c is just another source file for your compiler; optimizations would occcur only if you set them in your compiler options.

Re: [sqlite] [SQLite]Basic query
Hi, Clemens and Martin, Thank you for your prompt responses. How exactly are you using SQLite in your program? If you are not using the SQLite C API (sqlite3_* functions) directly, I'm using sqlite APIs for calling from C source code directly. which Version of VC++ do you use? I'm using Visual studio express 2010. why do you want to debug into the sqlite.c file? Since opening database API is failed, I'm trying to figure out the cause. The file sqlite.c is just another source file for your compiler; optimizations would occcur only if you set them in your compiler options. Yeah.. I completely agree with you, but I can't find such setting in VC++ property, So I'm asking this query...

Re: [sqlite] [SQLite]Basic query
Hi Shinichiro, If opening the database failed with sqlite3_open() != SQLITE_OK, it is probably best to check the return code and error message using sqlite3_errmsg(). It will give a strong hint. Debugging into the sqlite3 code itself never worked for me. Make sure that - the directory the database file redsides in exists - the the user executing the program has the permission to read/write in the directory and the database file This is not really the answer to your question, but you can probably solve your problem without debugging into sqlite.

As someone else said, the problem is that the Visual C++ debugger doesn't play nice with files in excess of 64KiB lines. When I had this need a couple years ago, I carefully split the sqlite3.c file into several pieces and compiled them separately.
