Hi there, I have added the CMake file to misc maths and the missing source files to utils so that cmake runs ok without errors. However on make i get the following [sled 10.2 x86_64 , fsl 4.1.3 (sources) ] error. Could you point me in the right direction ? Cheers, Spiro Linking C static library ../../lib/libprob.a [ 14%] Built target prob Scanning dependencies of target miscmaths [ 15%] Building CXX object fsl/miscmaths/CMakeFiles/miscmaths.dir/miscmaths.o In file included from /gpfs/software/fsl/4.1.3/src/fslview/fsl/miscmaths/miscmaths.cc:14: /gpfs/software/fsl/4.1.3/src/fslview/fsl/miscmaths/miscprob.h:16:21: error: libprob.h: No such file or directory make[2]: *** [fsl/miscmaths/CMakeFiles/miscmaths.dir/miscmaths.o] Error 1 make[1]: *** [fsl/miscmaths/CMakeFiles/miscmaths.dir/all] Error 2 make: *** [all] Error 2
