placement_classification_table.cpp does not compile

[dougwyu]

i downloaded placement_classification_table.cpp from https://gist.github.com/lczech/24c12a912e4eb0ed38d517d887c42db5

placed into genesis-0.19.0/apps and ran make update

compiled failed

(compiled has succeeded for all the cpp files in the doc/demos folder and also for merge_jplace_files.cpp)

Hi @dougwyu,

the program was written for genesis v0.11.0, which is mentioned in the description of the file, but probably not well visible there... So, simply download the respective release from here, then it should work!

hi Lucas,

I tried compiling genesis 0.11.0 and 0.11.1, and i got errors.

I'm running cmake 3.3.1 and gcc 4.9.3

Hi,

it seems that the wrong compiler was used. The second line of your output says The CXX compiler identification is GNU 4.4.7, which is too low for genesis. You might need to have a look at your CMake environment and set the compiler properly. Usually, something like export CXX=... in your shell prior to building works.

ah, that was it. i fixed the CC and CXX variables.

thanks

Nice! So I guess, this issue can be closed? If you have any more trouble with this, feel free to reopen ;-)

[dougwyu]

for others who might have trouble with this:

get your gcc and g++ paths and record them

which gcc # e.g. my path is: /gpfs/software/compilers/gcc/4.9.3/bin/gcc which g++

then run these in your shell, substituting in the paths to your gcc and g++

export CC = /gpfs/software/compilers/gcc/4.9.3/bin/gcc
export CXX = /gpfs/software/compilers/gcc/4.9.3/bin/g++
