Program received signal SIGSEGV, Segmentation fault. 0x0047b2ea in ParseCommandLine (cmdline=<value optimized out>, argv=0x0) at ./src/main/win32/SDL_win32_main.c:100 100 while ( *bufp && ( *bufp != '"' || *lastp == '\\' ) ) { (gdb) bt #0 0x0047b2ea in ParseCommandLine (cmdline=<value optimized out>, argv=0x0) at ./src/main/win32/SDL_win32_main.c:100 #1 0x0047b5bb in WinMain@16 (hInst=0x400000, hPrev=0x0, szCmdLine=0x81c530e0 "a \"\" b", sw=10) at ./src/main/win32/SDL_win32_main.c:374 #2 0x0047af28 in main () --- The problem is that on Windows when you make a shortcut, and want it to accept drag-and-dropped files, the good way to make it work work with files that have spaces in their names or paths is make this argument "%1" (with the surrounding quotes). But then when you run it without dropping a file into it, it's resolved as "", and triggers this bug. --HG-- branch : SDL-1.2
Simple DirectMedia Layer
(SDL)
Version 1.2
---
http://www.libsdl.org/
This is the Simple DirectMedia Layer, a general API that provides low
level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL,
and 2D framebuffer across multiple platforms.
The current version supports Linux, Windows CE/95/98/ME/XP/Vista, BeOS,
MacOS Classic, Mac OS X, FreeBSD, NetBSD, OpenBSD, BSD/OS, Solaris, IRIX,
and QNX. The code contains support for Dreamcast, Atari, AIX, OSF/Tru64,
RISC OS, SymbianOS, Nintendo DS, and OS/2, but these are not officially
supported.
SDL is written in C, but works with C++ natively, and has bindings to
several other languages, including Ada, C#, Eiffel, Erlang, Euphoria,
Guile, Haskell, Java, Lisp, Lua, ML, Objective C, Pascal, Perl, PHP,
Pike, Pliant, Python, Ruby, and Smalltalk.
This library is distributed under GNU LGPL version 2, which can be
found in the file "COPYING". This license allows you to use SDL
freely in commercial programs as long as you link with the dynamic
library.
The best way to learn how to use SDL is to check out the header files in
the "include" subdirectory and the programs in the "test" subdirectory.
The header files and test programs are well commented and always up to date.
More documentation is available in HTML format in "docs/index.html", and
a documentation wiki is available online at:
http://www.libsdl.org/cgi/docwiki.cgi
The test programs in the "test" subdirectory are in the public domain.
Frequently asked questions are answered online:
http://www.libsdl.org/faq.php
If you need help with the library, or just want to discuss SDL related
issues, you can join the developers mailing list:
