Hi, I've built a static gsl-1.11 on Win32 (Vista) in the MSYS shell using the MinGW port of gcc-3.4.5. But the library seems to be mssing the following symbols (which are to be found in gsl_block_complex_long_double.h and gsl_block_long_double.h): `gsl_block_complex_long_double_fscanf' `gsl_block_complex_long_double_fprintf' `gsl_block_complex_long_double_raw_fscanf' `gsl_block_complex_long_double_raw_fprintf' `gsl_block_long_double_fscanf' `gsl_block_long_double_fprintf' `gsl_block_long_double_raw_fscanf' Anyone know why that might be ? Microsoft Compilers won't be able to handle long doubles - though MinGW certainly can. (However, MinGW uses the Microsoft C runtime, and I'm not sure how that might impact on fprintf and fscanf of long doubles.) The config.log is attached. During the running of 'make check', the 'monte' test fails, but all other tests pass. Cheers, Rob
