Able to use umfpack in debug configuration, but not in release configuration

[Lucas Myers]

Hi all,

I've used the #include <deal.II/lac/sparse_direct.h> command in a program in order to use UMFPack. I'm able to compile and run everything fine in Debug mode (provided by Eclipse via the cmake4eclipse add-on). However, when I try to switch to Release mode to optimize the program, it gives me the following warning:

/usr/local/include/deal.II/lac/sparse_direct.h:31:12: fatal error: umfpack.h: No such file or directory

 #  include <umfpack.h>

            ^~~~~~~~~~~

This is confusing to me because, given that I can use UMFPack in Debug mode, I must've installed it properly during the dealii installation.

Let me know if you have any tips on how to fix, or if you need more information.

Thanks so much for any help,

Lucas

Hi folks,

Excuse me, the problem was on my end -- when using cmake4eclipse, you have to specify that you want to use the "CMAKE_EXPORT_COMPILE_COMMANDS parser" as the provider in the "Preprocessor Includes, Paths, Macros, etc." tab for your project for both the Release and Debug configurations.

Given that the problem was a silly mistake on my end, ought I delete the forum post?

Thanks,

Lucas

Hi Lucas,

I’m glad that you managed to solve this issue yourself.

Given that you’ve explained what you did to fix the problem, this is useful information for all. So we’ll leave the thread in place just in case someone has a similar issue in the future.

Best,

Jean-Paul
