The HDF5 C library intentionally performs these exceptions. - Therefore, the "-ieee=full" nagfor switch is necessary when compiling a program - to avoid stopping on an exception. - CMake files do not behave correctly with paths containing spaces. Do not use spaces in paths because the required escaping for handling spaces results in very complex and fragile build files. |
