Installed, just not linked

Question

Note: I\'m not so good at using shell.

I was trying to install Valgrind using brew on Yosemite.

brew install --HEAD valgrind<

Answer 1

I had same problem and i resolved with next solution: Run brew doctor from Terminal to check all your errors

then run next command:

sudo chown -R $USER:admin /usr/local/bin /usr/local/etc /usr/local/sbin /usr/local/share

after run:

brew link <package_name>

Answer 2

Looks like a permission issue. I would try doing this

chmod 755 /usr/local/lib/pkgconfig

This should make that available, then try

brew link valgrind

If that doesn't work I would try doing a check on it

brew doctor

Answer 3

In my case, brew doctor got it right. At some point /usr/local/lib/pkgconfig was set to be owned by root rather than my account. The prescribed remedy worked -

sudo chown -R $(whoami) /usr/local/lib/pkgconfig

Answer 4

I got a similar problem,

$ brew install sqlite Updating Homebrew... ==> Auto-updated Homebrew! Updated 1 tap (homebrew/core). No changes to formulae.

Warning: sqlite-3.17.0 already installed, it's just not linked.

I tried to link it,

$ brew link sqlite Warning: sqlite is keg-only and must be linked with --force Note that doing so can interfere with building software.

Then do it by force,

$ brew link --force sqlite Linking /usr/local/Cellar/sqlite/3.17.0... 8 symlinks created

Answer 5

I had same a problem about permission, but after I give my permission, still error permission. And here I do, first:

brew unlink valgrind

and then,

brew link valgrind

hope this help.

Answer 6

Type

link valgrind

It will show an error that it can't be linked because such-and-such directory is not writable. Cool, we make it writable now. Type

sudo chmod a+w the/directory/shown/as/error

If the directory is not writable, you wont be able to change its permission and make it writable either. Sudo will make this operation possible. chmod will change the mode and will make all(a) users be able to write(w) it.

Next you will be prompted to type your system's password. After this, again type

link valgrind

and it will work this time.
