Source: ghdl
Version: 0.36+20190617
Severity: serious
Tags: ftbfs
Justification: fails to build from source (but built successfully in the past)
When Debianized GHDL package is build it fails with message
Error: No installed ghdl backend found. Terminating!
in context
install -m 755 -p libghdl-0_37_dev.so ../../debian/tmp/usr/lib/ghdl/mcode/
../../debian/tmp/usr/bin/ghdl --disp-standard --std=87 >
../../debian/tmp/usr/lib/ghdl/mcode/vhdl/src/std/standard.v87
Error: No installed ghdl backend found. Terminating!

dpkg-buildpackage: error: fakeroot debian/rules binary subprocess returned
exit status 2
The reason for the problem is the file /debian/ghdl.wrapper which prevents
install when there is not already installed some "ghdl" package because
it ignores "ghdl-mcode" already redy to be run in "debian/tmp/usr/bin"
directory.
Extending of file to find executables in the wrapper directory
solves the problem
