@sseemayer Hi，I met a problem when using CCMpred: (base) czh@X12DAi-N6:~/CCMpred$ make [ 7%] Building C object lib/libconjugrad/CMakeFiles/conjugrad.dir/src/conjugrad.c.o In file included from /home/czh/CCMpred/lib/libconjugrad/src/conjugrad.c:4: /home/czh/CCMpred/lib/libconjugrad/include/conjugrad.h:21:15: error: conflicting types for ‘sqrt’; have ‘float(double)’ 21 | #define fsqrt sqrt | ^~~~ In file included from /usr/include/features.h:486, from /usr/include/x86_64-linux-gnu/bits/libc-header-start.h:33, from /usr/include/math.h:27, from /home/czh/CCMpred/lib/libconjugrad/src/conjugrad.c:4: /usr/include/x86_64-linux-gnu/bits/mathcalls.h:143:1: note: previous declaration of ‘sqrt’ with type ‘double(double)’ 143 | MATHCALL (sqrt,, (Mdouble x)); | ^~~~~~ make[2]: [lib/libconjugrad/CMakeFiles/conjugrad.dir/build.make:76：lib/libconjugrad/CMakeFiles/conjugrad.dir/src/conjugrad.c.o] Error 1 make[1]: [CMakeFiles/Makefile2:129：lib/libconjugrad/CMakeFiles/conjugrad.dir/all] Error 2 make: *** [Makefile:156：all] Error 2

Could you help me? Thanks!

Have you solved your problem？ I have the same problem as you，and I am not able to solve it. If you have saved it,can you teach me?

[Benny0323]

Sorry, I still solve it unsuccessfully. May be you can ask other people for help.

[ylx0925]

OK,thank you!

Hi, not sure if you still care, but I also stumbled upon this problem. What worked for me was opening the file "include/conjugrad.h" and simply commenting out the offending line by adding // in front of it.
