problem with make

[zjlahey]

Trying to make and receive the following error:

g++ -Wall -O3 -fopenmp -Ilib -ldl -o ntcard ntcard.cpp lib/Uncompress.cpp lib/SignalHandler.cpp lib/Fcontrol.cpp
/usr/bin/ld: /tmp/cczwFT7G.o: undefined reference to symbol 'dlsym@@GLIBC_2.2.5'
/usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/libdl.so: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
Makefile:12: recipe for target 'ntcard' failed
make: *** [ntcard] Error 1

Any help would be appreciated. Thank you!

There's a bug in the Makefile. The -l options need to appear after the source file ntcard.cpp

g++ -Wall -O3 -fopenmp -o ntcard ntcard.cpp lib/Uncompress.cpp lib/SignalHandler.cpp lib/Fcontrol.cpp -Ilib -ldl

You may want to try using Linuxbrew to install ntcard See http://linuxbrew.sh then brew install homebrew/science/ntcard

Thanks for you help, but I still can't get it to work. I installed linuxbrew and it doesn't recognize ntcard:

brew install homebrew/science/ntcard
Error: No available formula with the name "homebrew/science/ntcard" 
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...
Error: No formulae found in taps.

I've also tried editing the make file to no avail.

I just pushed the AUTOTOOLS version to build ntCard. Please follow the instruction in README.md to build ntcard and let me know if it works.

It works, thanks!

My mistake, ntcard wasn't yet in Homebrew, but it is now! See https://github.com/Homebrew/homebrew-science/pull/4846 Try once again

brew install homebrew/science/ntcard
