ChucK-1.3.3.0 - Problem with source & compilation [Linux-Mint]
by Lionel Atty 29 Nov '13

29 Nov '13

Hey Guyz ! A minor problem in the source code for linux compilation: util_string.cpp: In function ‘std::string get_full_path(const string&)’: util_string.cpp:393:14: erreur: ‘PATH_MAX’ was not declared in this scope util_string.cpp:395:42: erreur: ‘buf’ was not declared in this scope make: *** [util_string.o] Erreur 1 Just need to add this lines in util_string.cpp at lines 387: #ifndef PATH_MAX #include <linux/limits.h> // for PATH_MAX definition #endif Enjoy, YOOoOYoOoOo

chuck --shell writes to root directory under Windows
by Steve Nicholson 26 Nov '13

26 Nov '13

When investigating the issue I reported earlier today, my classmates and I discovered that under Windows chuck --shell writes its temporary file to c:\. This will most likely fail if the user doesn't have admin rights. This is apparently because the tmpnam function under Windows only returns a file name whereas under OS X it returns a file name that includes a complete path to the system's temporary directory. I used the information from this article (http://msdn.microsoft.com/en-us/library/windows/desktop/aa363875(v=vs.85).a…) to create a temporary file name that includes a path to an appropriate directory. Here is the diff for chuck_shell.cpp: 606a607,623 > #if defined __PLATFORM_WIN32__ > char * tmp_filepath = NULL; > TCHAR tempFileName[MAX_PATH]; > TCHAR tempPathBuffer[MAX_PATH]; > DWORD dwRetVal = 0; > UINT uRetVal = 0; > dwRetVal = GetTempPath(MAX_PATH, tempPathBuffer); > if (dwRetVal > 0 && dwRetVal < MAX_PATH) > { > uRetVal = GetTempFileName(tempPathBuffer, TEXT("ChucK"), 0, tempFileName); > if (uRetVal != 0) > { > //Successfully created temp file name. Point tmp_filepath at it. > tmp_filepath = tempFileName; > } > } > #else 607a625,626 > #endif > -Steve

Error in chuck --shell under Windows - with potential fix
by Steve Nicholson 26 Nov '13

26 Nov '13

One of my fellow students in the Coursera ChucK class found a bug in chuck --shell under Windows. When using "{" and "}" to enter ChucK code to be interpreted, he got the error: [chuck]: unrecognized escape sequence: \s [chuck]: malformed filename + argumentlist... --> '\s2i8.7'add: error: command failed I tracked it down to util_string.cpp. The extract_args function is interpreting backslashes as the beginning of an escape sequence, not taking into account that Windows file paths can contain backslashes. I made this change which works. I've only done basic testing, though. 266c266,270 < if( s[i] == '\\' && (i+1) < s.length() ) --- > #ifdef __PLATFORM_WIN32__ > if( s[i] == '\\' && (i+1) < s.length() && filename != "") // Wait until after parsing a filename before looking for escape sequences > #else > if( s[i] == '\\' && (i+1) < s.length()) > #endif -Steve

Bug with Bowed
by Philipp Kroos 24 Nov '13

24 Nov '13

I think there is a bug in the ugen_stk code for Bowed, is that known? Someone in the currently ongoing coursera class found that .rate is not accepted by the compiler. I looked into the code and actually it seems as if the according members are not announced/created for the ChucK VM. I could fix it adding these lines, though I don't know if it's working correctly. But at least you'll know what I mean :) func = make_new_mfun( "float", "rate", Bowed_ctrl_rate ); //! rate func->add_arg( "float", "value" ); if( !type_engine_import_mfun( env, func ) ) goto error; func = make_new_mfun( "float", "rate", Bowed_cget_rate ); //! rate if( !type_engine_import_mfun( env, func ) ) goto error; Best, Philipp

weird crash
by Philipp Kroos 24 Nov '13

24 Nov '13

Hi guys, I can reliably crash the VM with the following file if I uncomment the crashes()-function call. Sorry for the formatting. The really most weird thing is that the crash is 'triggered' only if I loop more then 4 times... Following the file you'll find the output of uname -a and chuck --version, and the backtrace. I wasn't sure if I should post here or on the users list, but since I'm a programmer I decided for this list. So let me know if you have any ideas that I could try out. Cheers, Philipp /* chuck file start */ fun int dontCallMe () { } fun int iamOk () { return 0; } fun void crashes () { for (0 => int j; j < 5; j++) { dontCallMe (); 1::ms => now; } } fun void
