            Bug ID: 98409
           Summary: Installing g++-mapper-server fails when cross
                    compiling to Windows
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: markus.boeck02 at gmail dot com
  Target Milestone: ---

Current version of trunk GCC (1b021bbd85a79c9d16c1359cbc23b608685dfd9f) fails
to compile when cross compiling GCC to Windows due to a install command trying
to install g++-mapper-server even though the file is named
g++-mapper-server.exe which does exist. 

 make:
/usr/bin/install: cannot stat 'g++-mapper-server': No such file or directory
make[2]: *** [../gcc/g++-mapper-server] Error 1
make[1]: *** [all-c++tools] Error 2
make[1]: *** Waiting for unfinished jobs....

That is weird,
$ grep mapper-server Makefile.in 
        rm -f g++-mapper-server$(exeext)
all::g++-mapper-server$(exeext)
g++-mapper-server$(exeext): $(MAPPER.O) $(CODYLIB)
all::../gcc/g++-mapper-server$(exeext)
../gcc/g++-mapper-server$(exeext): g++-mapper-server$(exeext)
        $(INSTALL_PROGRAM) g++-mapper-server$(exeext)
$(DESTDIR)$(libexecsubdir)

What is exeext set for you in c++tools/Makefile ?

--- Comment #2 from Markus Böck <markus.boeck02 at gmail dot com> ---
That is indeed weird.

At the top of the Makefile it says:
EXEEXT := .exe

and further down in the Makefile:

g++-mapper-server$(exeext): $(MAPPER.O) $(CODYLIB)
        +$(CXX) $(LDFLAGS) -o $@ $^ $(VERSION.O) $(LIBIBERTY)

# copy to gcc dir so tests there can run
all::../gcc/g++-mapper-server$(exeext)

../gcc/g++-mapper-server$(exeext): g++-mapper-server$(exeext)
        $(INSTALL) $< $@

install::
        $(SHELL) $(srcdir)/../mkinstalldirs $(DESTDIR)$(libexecsubdir)
        $(INSTALL_PROGRAM) g++-mapper-server$(exeext)
$(DESTDIR)$(libexecsubdir)

which seems correct to me?

Yet running make gives:

I am using GNU Make 4.1 on an Ubuntu 18.04 WSL 1 Host in case that could be
important

--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Ah, no weird at all.
It should have been
exeext = @EXEEXT@
instead, if @EXEEXT@ is what one wants to use.  For crosses, especially
canadian, bet the exeext needed is the host exeext, not sure which one
configure computes here.
E.g. gcc/Makefile.in has separate:
gcc/Makefile.in:exeext = @host_exeext@
gcc/Makefile.in:build_exeext = @build_exeext@

It's me having a thinko about case sensitivity.

    c++tools: Fix exe suffix [PR 98409]

    I had a thinko about variable case, and, coupled with Make's behaviour
    of just consing up variables out of nothing, and linux not having an
    executable extension, didn't notice.
