Error building with hypre 2.24.0

[BBBBBbruce]

Hello, I am trying to build the cuda parallel version. The packages are mfem-4-3 hypre-2.24.0 metis-5.1.0.
however I received lots of errors

linalg/hypre.cpp:1268:9: error: ‘hypre_ParCSRMatrixOwnsColStarts’ was not declared in this scope; did you mean ‘hypre_ParCSRMatrixColStarts’? 1268 | hypre_ParCSRMatrixOwnsColStarts(A))) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | hypre_ParCSRMatrixColStarts linalg/hypre.cpp:1292:37: error: incompatible types in assignment of ‘HYPRE_BigInt*’ {aka ‘int*’} to ‘HYPRE_BigInt [2]’ {aka ‘int [2]’} 1292 | hypre_ParCSRMatrixRowStarts(A) = new_row_starts; | ^~~~~~~~~~~~~~ linalg/hypre.cpp:1293:4: error: ‘hypre_ParCSRMatrixOwnsRowStarts’ was not declared in this scope; did you mean ‘hypre_ParCSRMatrixRowStarts’? 1293 | hypre_ParCSRMatrixOwnsRowStarts(A) = 1; | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | hypre_ParCSRMatrixRowStarts linalg/hypre.cpp:1297:40: error: incompatible types in assignment of ‘HYPRE_BigInt*’ {aka ‘int*’} to ‘HYPRE_BigInt [2]’ {aka ‘int [2]’} 1297 | hypre_ParCSRMatrixColStarts(A) = new_row_starts; | ^~~~~~~~~~~~~~ linalg/hypre.cpp:1298:7: error: ‘hypre_ParCSRMatrixOwnsColStarts’ was not declared in this scope; did you mean ‘hypre_ParCSRMatrixColStarts’? 1298 | hypre_ParCSRMatrixOwnsColStarts(A) = 0; | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | hypre_ParCSRMatrixColStarts linalg/hypre.cpp: In member function ‘void mfem::HypreParMatrix::CopyColStarts()’: linalg/hypre.cpp:1304:14: error: ‘hypre_ParCSRMatrixOwnsColStarts’ was not declared in this scope; did you mean ‘hypre_ParCSRMatrixColStarts’? 1304 | if (!A || hypre_ParCSRMatrixOwnsColStarts(A) || | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | hypre_ParCSRMatrixColStarts

Looks like some re-naming issues, and there were too many of them.
These error goes off when I switch to hypre-2.16.0 as same in the instruction. I wonder if there is some features in the later version of hypre is needed? Or 2.16.0 is sufficient?

Thanks

also, I wonder if there is a tutorial on how can I build mfem as an external library that I can used for my own project? is it enough for me to just in include libmfem.a and the header files?

Hi @BBBBBbruce,

With hypre v2.24.0 you should use the newer mfem v4.4.

Regarding using mfem from your project: if you use GNU make, you can include the file config.mk (from the directory config/ in the build-tree or from the directory share/mfem/ in the install tree) -- this file provides a number of useful definitions (MFEM_*) that you can use to build with mfem; for example, see how the makefile in the examples/ directory use that file. If you are using CMake you can use the file MFEMConfig.cmake exported by mfem (in the root directory in the build-tree or in the directory lib/cmake/mfem/ in the install tree); for example, see how the CMake file in GLVis uses the MFEM exported CMake file: https://github.com/GLVis/glvis/blob/master/CMakeLists.txt.
