| Hello, I had a problem in blue using the new parser: as soon as there was a literal floating point value in the orchestra, i got an error about numeric values. It's a locale problem because in French, the decimal separator is a comma instead of a dot. I first thought that the problem was specific to blue and I transmitted the problem to Steven. But then Joachim Heintz signaled that he add the same problem with csoundQt and Tito Latini suggested that a solution might be to export LC_NUMERIC=C to force C syntax for floating point literals. I investigated in the csound sources and I found that the error comes from the strtod function used by csound in different files of the csound5/Engine dir: csound_orc_compile.c, express.c, linevent.c, otran.c, sread.c, and in csound5/Opcodes/ftgen.c We find this statement in csound5/Engine/otran.c (line306): setlocale(LC_NUMERIC, "C"); /* Ensure C syntax */ So, if otran is not used by the new parser, this could explain that we have not this problem with the old parser. I suggest to solve the problem by inserting the setlocale(LC_NUMERIC, "C"); statement in the csoundCreate function of the csound5/Top/csound.c source file, so that we are sure to have C syntax for literal floating point values in all cases (i.e. csound being launched from console, from a system call or through the API). I tried the solution here and it seems to work. If other developpers don't have any objection, I'll commit the patch to git when I'm back home this evening. Regards Francois |
