Source: graphviz
Version: 2.38.0-3
Severity: important
User: debian-al...@lists.debian.org
Usertags: alpha
Justification: fails to build from source but used to build
graphviz FTBFS on Alpha with a failed link of cmd/dot. From the build
log [1]

/usr/bin/ld: dot-dot.o: undefined reference to symbol
'feenableexcept@@GLIBC_2.2'
//lib/alpha-linux-gnu/libm.so.6.1: error adding symbols: DSO missing from
command line
This is a failure to link to feenableexcept() from the standard C maths
library.
Note that there is no "-lm" in the link command, but quoting from the
manpage for feenableexcept:
Link with -lm.
I attach a patch that adds the math library into the link of cmd/dot.
With the patch graphviz successfully builds on Alpha.
Interestingly graphviz only failed on Alpha for this reason; I do not
know how it succeeded to build on all other architectures!
Cheers
Michael
