Elmer Discussion Forum

Hello everyone,
I am facing some problems when installing Elmer on my macOS 12.6.
I am using cmake version 3.24.3 and Apple clang version 14.0.0 (clang-1400.0.29.102).

After cloning the code and generating the make files, make or make install gives this error:

[ 58%] Building C object fem/src/CMakeFiles/elmersolver.dir/CPUTime.c.o
/Users/victor/elmer/elmerfem/fem/src/Load.c:591:3: error: implicit declaration of function 'var_copy_transpose' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
var_copy_transpose(name,values,*nrows,*ncols);

I tried to solve this problem for a long time, but with no success. Can somebody give me a hint how to finish installing?
Thank you!

Hi

The "var_copy_transpose" is defined under matc. I wonder what is different on macOS compared to other systems that it does not find it. -Peter

Thanks for your quick reply!

Any idea how to tell macOS what it is..?

When I do the grep command, I get:
victor@victors-MBP-2 build % grep -r var_copy_transpose
Binary file ./matc/src/CMakeFiles/matc.dir/variable.c.o matches
Binary file ./matc/src/libmatc.dylib matches

Thanks for your answer.
I followed the hint given in that post. Now it finds several C99 "errors", wrong declarations, and so on in the Load.c file. It must be some problem with the compiler or so...
It's a fresh clone, homebrew, cmake freshly updated... No idea why it doesn't work.
