[nmag-users] Nmag compile error with recent versions of gcc, and solution

[Fangohr H.]

Dear all,

when using recent versions of gcc, for example, 4.8.2, the compile reports an error when processing the h5diff.c file from the hdf5-1.8.7 sources that come with the nmag all-in-one installation tar ball.

The error looks like the output attached at the end of this message.

The fix for this is to edit nmag-0.2.1/hdf5/tools/lib/h5diff.c and to change line 638 from

//int i1, i2;

to

/*int i1, i2;*/

The compilation should then proceed without errors (just type ‘make’ again).

This is required, for example, to compile nmag-0.2.1 on Ubuntu 14.04.

Best wishes,

Hans
