+ | ===== Known Problems ===== | ||
+ | |||
+ | ==== udunits1 and FMRC ==== | ||
+ | |||
+ | udunits1 does not differ between a date and a timespan, e.g. | ||
+ | < | ||
+ | $ ./udunits | ||
+ | You have: hours | ||
+ | You want: hours since 2010-01-01 00:00:00 | ||
+ | <hours since 2010-01-01 00: | ||
+ | <hours since 2010-01-01 00: | ||
+ | </ | ||
+ | |||
+ | Therefore, data with two time-axis, e.g. in [[http:// | ||
+ | test-failure: | ||
+ | < | ||
+ | unknown location:0: fatal error in " | ||
+ | testCoordinateSystemSliceBuilder.cc: | ||
+ | |||
+ | *** 1 failure detected in test suite " | ||
+ | FAIL: testCoordinateSystemSliceBuilder | ||
+ | </ | ||
+ | |||
+ | If you don't intend to use FMRC, you can ignore this error, otherwise, you should upgrade to udunits2. | ||
+ | |||
+ | |||
+ | ==== udunits1 and udunits2 ==== | ||
+ | |||
+ | If both udunits1 and udunits2 are available on the machine, fimex might prefer udunits1 unless explicitly disabled. To explicitly disable udunits1, use: | ||
+ | < | ||
+ | ./configure --without-udunits --with-udunits2 ... | ||
+ | </ | ||
+ | |||
+ | ==== MacOS X and gcc ==== | ||
+ | |||
+ | Under MacOS X strings may come in different flavour for gcc, either static or fully dynamic. Libraries compiled with one type of strings don't work well with programs/ | ||
+ | < | ||

+ | ./b2 install | ||
+ | </ | ||

+ | |||
+ | |||
+ | ==== AIX ==== | ||
+ | |||
+ | The boost libraries (1.44) are not compatible with the AIX XL/C++ compiler V10 and we had to compile boost and fimex with gcc to get it working under AIX. This might have been improved with newer versions of the AIX compiler, but hasn't been tested: http:// |
