configure: line 3335: syntax error near unexpected token `LZ4,'

After installing msys (standalone, not the one from devkitPro), devkitPro, devkitA64 and libnx on a Windows 10 Pro PC I wanted to build switch-tools so I ran autogen.sh and then configure.

configure gives me this output:

$ ./configure

./configure: line 3335: syntax error near unexpected token `LZ4,'
./configure: line 3335: `PKG_CHECK_MODULES(LZ4,'

To make sure this isn't a Windows error, I also tried building switch-tools on a Ubuntu 17.10 x64 virtual machine, but without installing libnx. Here the same error occurred.

I'm not really familiar with make, configure and the rest so I can not say what exactly the syntax error is or why it happens.

Build and install liblz4 from https://github.com/lz4/lz4

FWIW, devkitPro is not something you can build or install. devkitPro is an organisation dedicated to providing homebrew toolchains.

Installing liblz4 did not fix this syntax error, neither on Windows nor on Ubuntu.

What I meant by "installing devkitPro" is that I ran the devkitPro installer (the script on Ubuntu) and installed devkitARM, just to be sure where to copy the devkitA64 folder.

Hello,
Got the same issue here with last version of LZ4 (from github link repo WinterMute said) installed on Ubuntu 17.10.
Line failing at configure is (in my case) 3536. Message is the same.

checking dependency style of gcc... gcc3
./configure: line 3536: syntax error near unexpected token LZ4,' ./configure: line 3536: PKG_CHECK_MODULES(LZ4,'

Anything I can provide for further investigation?
Thanks for your effort.
Kapeas.

sudo apt-get install pkg-config

Thanks for the help. It worked :) Will keep testing the rest of the tools

I'm getting the same error, I tried running sudo apt-get install pkg-config and I even built liblz4 from source, but I'm still getting this syntax error.
