[Bug-glpk] Re: problem on compiling glpk 4.2 in Debian and Red Hat

[Andrew Makhorin]

Thank you for your bug report.

To avoid the bug please use the command:

   make LDFLAGS=-lm ...

The bug appears because the standard math library libm is not specified
in Makefile. (Interesting to note that on testing glpk 4.2 under Debian
GNU/Linux 2.2 there were no errors.)
