[SOLVED] ag: error while loading shared libraries: libpcre.so.3

Hi there!

I just tried to install ag (silver searcher). I installed it like suggested:

pacman -S the_silver_searcher

Now if I run `ag`, I get this error:

> ag: error while loading shared libraries: libpcre.so.3: cannot open shared object file: No such file or directory

I tried to fix this by installing `pcre` and `pcre2` package, without luck.

Does anyone know why libcre is missing and where I could get it from?

Re: [SOLVED] ag: error while loading shared libraries: libpcre.so.3

Could be a packaging bug, the current pcre package doesn't contain that file...

slithery@red:~$ pacman -Ql pcre | grep so
pcre /usr/lib/libpcre.so
pcre /usr/lib/libpcre.so.1
pcre /usr/lib/libpcre.so.1.2.9
pcre /usr/lib/libpcre16.so
pcre /usr/lib/libpcre16.so.0
pcre /usr/lib/libpcre16.so.0.2.9
pcre /usr/lib/libpcre32.so
pcre /usr/lib/libpcre32.so.0
pcre /usr/lib/libpcre32.so.0.0.9
pcre /usr/lib/libpcrecpp.so
pcre /usr/lib/libpcrecpp.so.0
pcre /usr/lib/libpcrecpp.so.0.0.1
pcre /usr/lib/libpcreposix.so
pcre /usr/lib/libpcreposix.so.0
pcre /usr/lib/libpcreposix.so.0.0.5

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

$ ldd usr/bin/ag 
	linux-vdso.so.1 (0x00007fff0cdac000)
	libpcre.so.1 => /usr/lib/libpcre.so.1 (0x00007f49bd68c000)
	liblzma.so.5 => /usr/lib/liblzma.so.5 (0x00007f49bd466000)

@slithery as ag from the arch package the_silver_searcher-2.1.0-1-x86_64.pkg.tar.xz does not appear to be linked to libpcre.so.3 third party library or binary

It's not missing, libpcre.so.3 is a the debian version of libpcre.so.0 (yeah, I don't get it either), nothing on Arch should depend on it.

feluxe, please install pax-utils and use lddtree to identify where this dependency is coming from.

# pacman -S pax-utils
$ lddtree /usr/bin/ag

Re: [SOLVED] ag: error while loading shared libraries: libpcre.so.3

Slithery, you are right, that file is not in the current pcre package.  It is also not linked to by the current the_silver_searcher package.

feluxe, don't be a smart-ass.  Implement the correct solution provided and say thank you. (edit: after the follow up I realize I may have interpreted sacasm in feluxe's post where it wasn't intended.  If so, sorry feluxe.)

(EDIT: whoa, double snaked on that one)

pacman -Syu

This did the trick. I only saw jasonwryan's comment when I posted my last post. Thought it was clear. Thanks anyways
