questions about installing llvm

Project Infrastructure LLVM Dev List Archives

Hi,

I tried to install LLVM in our server, but after successfully compiling it, the installation failed. The reported error is:

llvm[1]: Installing HTML documentation

/usr/dcs/software/supported/bin/ginstall: invalid option – C

Try `/usr/dcs/software/supported/bin/ginstall --help’ for more information.

gmake[1]: *** [install-html] Error 1

gmake[1]: Leaving directory `/home/software/llvm/docs’

gmake: *** [install] Error 1

I am wondering if some specific version of the install program is required. Please help me to check out what is going wrong here. Thanks!

/usr/dcs/software/supported/bin/ginstall is version 4.0, whereas Fedora
Core 1 (which is QUITE old) has /usr/bin/install version 5.0 .

Even install-4.5.3 has the -C switch. For now, manually change your
Makefile.config in your build directory to have the line

INSTALL := /usr/bin/install -c

instead of

INSTALL := /usr/dcs/software/supported/bin/ginstall -c

and you should be fine, assuming your /usr/bin/install is more recent.

In the future, we should allow a configure switch choose the install
program, and it might already do that with --with-install=[path], but I
am not sure and haven't checked.

Actually, Misha, that won't work.

The -C option is used directly in docs/Makefile. So the change will have
to go into docs/Makefile. Either that or upgrade install to version 5.

Sorry, Reid, but I think it will, for the following reason:

I don't really know what the -c (lowercase) option does, but install
says it's ignored anyway, so that's irrelevant for GNU install. We're
talking about the -C option (uppercase).

The -C option is used directly in docs/Makefile. So the change will have
to go into docs/Makefile. Either that or upgrade install to version 5.

docs/Makefile uses $(INSTALL) -C (uppercase).

My point is that /usr/dcs/..../ginstall doesn't accept -C but
/usr/bin/install does.

Changing it in Makefile.config will do the trick.

You were advocating changing the INSTALL variable to use -c instead of
-C, so in docs/Makefile the command:

$(INSTALL) -C ...

would be expanded as:

/usr/bin/install -c -C ...

which still won't work.

Reid.

Okay, my bad. I didn't realize that /usr/bin/install was the *new*
version of install and would accept -C as an option.

It works. Thanks!

However, although the configuration and installation process doesn't report
any error/warning, the llvmc cannot work. It just says: Unexpected unknown
exception occurred :frowning:

Do you have any clue about that?

Have you compiled and installed llvm-gcc/llvm-g++? llvmc is not a
compiler, it's just a compiler driver, so it expects all the tools to be
in the path (llvm-gcc, gccas, gccld, opt, etc.)

Furthermore, if llvmc does not work for you, just use llvm-gcc directly,
assuming the rest of llvm tools are in your path.

Can you send us information on how to reproduce the bug? We'd like to get it fixed if possible. Are you using mainline CVS?

Yes. I forgot to mention that the frontend (llvm-gcc, llvm-g++) works well
:slight_smile: I will try other tools later. Thanks!
