failed to compile `diesel_cli v0.6.1`./usr/bin/ld: cannot find -lpq, cannot find -lsqlite3

Hi, I'm very love rust and very interesting in your project. Currently I'm building a simulation training system using iron, diesel and other rust crates. But when I try to install diesel_cli followed your "getting start" doc, using "cargo install diesel_cli" in bash. But it failed:

error: failed to compile `diesel_cli v0.6.1`, intermediate artifacts can be found at `/tmp/cargo-install.j1yQaQUZOGv2`

Caused by:
  Could not compile `diesel_cli`.

I've noticed this issue: #286. But how can make sure pg_config is on the path, or libpq is in /usr/local/include or some other path that ld can see.
I'm using ubuntu 15.10, postgresql and sqlite3 have been installed. libpq and libsqlite3 are in path "/usr/lib/x86_64-linux-gnu".
My "/etc/ld.so.conf"are:

include /etc/ld.so.conf.d/*.conf

My "/etc/ld.so.conf.d/x86_64-linux-gnu.conf" are:

# Multiarch support
/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu

So, how can i solve this problem, thank you!

Most of the time pg_config will be installed to /usr/bin/pg_config, which is almost definitely on your $PATH. To try and find it on your machine, you could run sudo updatedb && sudo locate pg_config, which will list the absolute paths of files that match. If it's not anywhere, that means you're missing libpq-dev, and will need to install that.

If you're not looking for sqlite support, you should install diesel_cli with

cargo install diesel_cli --no-default-features --features postgres

which won't compile the sqlite libs. If you do want sqlite support, you'll also need to install sqlite on your machine.

@mcasper pg_config is installed to /usr/bin/pg_config in my machine. And it is on my $PATH. But the error still exists.

fuying@fuying-linux:~$ echo $PATH
/home/fuying/.multirust/toolchains/nightly/cargo/bin:/home/fuying/.multirust/toolchains/nightly/bin:/home/fuying/.cargo/bin:/usr/lib/postgresql/9.4/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

Do you also have libpq installed?

[mann-ed]

I had the same issue. I found that my postgresql lib was under /usr/pgsql-9.3/lib/. So i symlink the libpq.so.5 to /usr/lib/libpq.so

sudo ln -s /usr/pgsql-9.3/lib/libpq.so.5 /usr/lib/libpq.so

Then it compiled just fine. I'm on Fedora and have postgresql93-libs installed.

Hope that helps.

[fuyingfuying]

@sgrif Yes, I have installed libpq. I used the method of @mann-ed . And it works. Thanks for your help

[fuyingfuying]

@mann-ed Use your method, and it works, Thanks for your help

[sgrif]

I do want to see if we can improve this scenario, as it's a common stumbling point. Can you tell me what the output of pg_config --libdir is when the symlink isn't there? We may need to ask pg_config for the specific file to link against or something.

[fuyingfuying]

@sgrif
On my computer, 'pg_config' is not installed:

fuying@fuying-linux:~$ pg_config --libdir
You need to install postgresql-server-dev-X.Y for building a server-side extension or libpq-dev for building a client-side application.

[sgrif]

@fuyingfuying In #321 (comment) you said it was... Anyway that looks like the root of the problem here, and the message given is definitely the correct solution. I'll see if I can improve the error message in pq-sys when pg_config isn't installed

[fuyingfuying]

@sgrif
ok

[xahon]

I just stucked into the same error. I had already installed libpq5 and libmysqlclient20 on my pc. Solution was sudo apt install libpq-dev libmysqlclient-dev and everything compiled successfully with cargo install diesel_cli without extra parameters

[alejandrotamayo]

@mann-ed method worked for me in linux mint.
thank you very much!!!
