Hi all,

I am trying to add an .hpp and .cpp file to Common/include and Common/src, but am have trouble building SU2. I'm 99% sure the issue lies within my Common/lib/Makefile.am. I've edited Makefile.am to list my added files and I have gone through the autotools documentation a few times, but still not sure what I'm doing wrong.

The error I get when trying to make SU2 is:
make[1]: *** No rule to make target '../src/MYNEWFILE.cpp', needed by '../src/libSU2Core_a-MYNEWFILE.o'. Stop.
Makefile:441: recipe for target 'install-recursive' failed
make: *** [install-recursive] Error 1

My procedure for building everything is as follows:
$ ./bootstrap (according to the documentation this will also call autreconf and remake Configuration and Makefile.in 's )
$ ./configure --prefix=/home/user/Documents/SU2-6.2.0 CXXFLAGS="-O3" --enable-mpi --with-cc=/usr/bin/mpicc --with-cxx=/usr/bin/mpicxx
$ make -j 16 install

Could someone please give me a very explicit example of editing Makefile.am and re-building SU2?

Thank you

Update:


Took my code from Ubuntu 16.04 to a CentOS 7 machine and everything compiled just fine. I don't understand why its working now, but I'm not complaining

Always good to do a "make clean" after changes to make files, just in case...

What the error you had often indicates is that the object (*.o) files from a previous compilation are confusing the compiler because of a change in the dependencies between files. The compiler will often not recompile an object if it's source hasn't been updated - but as you have found this can miss things when there is a new file dependency that was not there before. You can get around this either by using 'make clean' as a previous commentor stated (which removes ALL the object files), or by deleting just the .o file that's causing the problem if you'd like to try and save some time during the compilation process. Using 'make clean' is generally the safer bet. You can also use 'touch filename.cpp' to update the timestamp on the files giving the errors and trick the compiler into thinking it's been updated recently.
