1.36.1 installation issue

Dear all,

I’m having problems installing Mothur version 1.36.1 on our linux server (/bin folder). I download the 1.36.1 “source code” .zip-file from Github, and extract to my “/bin/mothur”-folder on the server. Then, I nano open the “makefile”, comment out the “TARGET_ARCH” line (as I am not using Windows) and uncomment the “CXXFLAGS” line (as I am installing on a linux system).

I then run the “make” command, the code starts compiling, but after a while I get the following error message:

/usr/bin/ld: cannot find -lm
collect2: ld returned 1 exit status
strip: ‘uchime’: No such file
ls: cannot access uchime: No such file or directory
sum: uchime: No such file or directory
make: *** [uchime] Error 1

Does anyone know why this happends, and/or have suggestions to how I may install Mothur 1.36.1 correctly?

All answers are appreciated!

Basically it can’t find the library m.

On Debain libm.so is provided by libc6-dev, fedora/rpm based I believe it’s glibc-devel
