[LLVMdev] llvm-config!

[Reza Sheykhi]

 Hi,

I am trying to install a program that works just with llvm-2.8. I have installed it but while i am trying to run llvm-config it says no such file or directory:

bash: /usr/bin/llvm-config: No such file or directory Does any body know how to solve this problem? I can use apt-get but it gives me either 2.9 or 3.0 or higher versions.

Thank you,
Reza

Could you give us more information? If your package manager does not
have 2.8 (I would hope it doesn't! that version is very old!), I would
recommend downloading 2.8 from http://llvm.org/releases/, and then
building it yourself.

Are the other llvm executables installed on /usr/bin ?

Does llvm-config exists on the `bin' subdirectory you used for
building LLVM? When you execute `make install' is it listed along the
other LLVM files that are copied to the destination directories?

And the basics: how are you building LLVM? (list explicit commands, etc)

Hi,

Thank you for your repky. I downloaded llvm-2.8 and installed it by first ./configure and then ./make it. It was installed in /usr/local as i expected. However, when i tried to run llvm-config-2.8, for example --version, it was not ran. Then, I used apt-get to installed the llvm-2.8-dev to have llvm-config. Did i do anything wrong? Also i do not know if these two installed llvms are linked together!

Thank you,
Reza

What's the output of this commands:

which perl

which llvm-config

which llvm-as

/usr/local/bin/llvm-config --version

/usr/bin/llvm-config --version


?

[Reza Sheykhi]

I got the following answers:

which perl
/usr/bin/perl

which llvm-config
/usr/local/bin/llvm-config

which llvm-as
/usr/local/bin/llvm-as

/usr/bin/llvm-confing --version
bash: /usr/bin/llvm-confing: No such file or directory

/usr/local/bin/llvm-config --version
2.8

Uh, there is a typo on the command above, it should be

/usr/bin/llvm-config --version

> /usr/local/bin/llvm-config --version
> 2.8

Okay, so lets suppose that something tried to use /usr/bin/llvm-config,
which doesn't exists, when it should use /usr/local/bin/llvm-config.

Do you see the message about the nonexistent /usr/bin/llvm-config when
you try to build or execute the other package that depends on LLVM?
Maybe it has the path to llvm-config hard-coded. Does it provide an
option for declaring where LLVM is installed? If no, you can solve the
problem with symlinks, although it may be tedious, or you may install
LLVM on /usr instead of /usr/local. This is achieved by configuring LLVM
with --prefix=/usr on your LLVM `configure' script invocation.

Hi,
Actyally you were right about the typo. When I fixid it, it worked and
i could get 2.8 for the "llvm-config --version" command. So i could
get 2.8 for both the path! What can be the problem then? I will copy
the error that i get to the end of this email, but let me ask some
other questions before copying it:

- How can I make sure that my LLVM is working correctly? I tried to
run the hello-world example. I could get the exe file and execute it,
but when I want to use the .bc file it gives me segmentation fault!

- Can I use llvm-g++ instead of clang? or any other instruction which
was availble when llvm-2.8 was released?

- My ubuntu (wubi) is 64. Could the problem be related to it? or llvm
works perfectly of 64 too?

- the error that i get for installing PinaVM, which can just use
llvm-2.8, is about linking and is as follows:
